BACKGROUND OF THE INVENTION
Field of the Art
[0002] The disclosure relates to the field of health and fitness
devices, and more particularly to the field of devices designed to
provide feedback regarding range of motion and balance.
Discussion of the State of the Art
[0003] It is currently the case that exercising machines and
systems exist that allow individuals of many different physical
abilities to exercise many different parts of their body, or their
entire body, at once. Some systems that allow this integrate with
phone systems and some manner of online user profile, or a local
user profile, which allows users to keep track of exercise they
have completed or their approximate fitness level based on their
performance. However, for elderly and at-risk individuals, there
are no systems which simultaneously may be capable of warning an
individual if they are about to stumble or fall based on posture or
exercise performance, or help train their balance by providing
feedback and warnings so that such stumbles and falls do not take
place. Elderly and at-risk individuals may for example, take
advantage of a treadmill, but there is currently no treadmill or
walking exercise device which warns or assists a user in training
their balance if they are prone to falling or stumbling during
routine exercise. This proves to be a problem for many individuals
who need to continue routine exercise but who may have difficulty
performing it for physical reasons.
[0004] What is needed then, is a system and method for range of
motion analysis and balance training while exercising.
SUMMARY OF THE INVENTION
[0005] Accordingly, the inventor has conceived and reduced to
practice, a system and method range of motion analysis and balance
training while exercising.
[0006] According to a preferred embodiment, a system for range of
motion analysis and balance training while exercising has been
devised, comprising: an exercise machine; and a first sensor
connected to or integrated into the exercise machine, and
configured to detect the angle of a user's torso away from
vertical; and at least one additional sensor connected to or
integrated into the exercise machine configured to detect the range
of motion of at least one portion of the user's body; and a range
of motion analyzer, comprising at least a plurality of programming
instructions stored in the memory of, and operating on at least one
processor of, a computing device, wherein the plurality of
programming instructions, when operating on the processor, cause
the computing device to: receive data from the at least one
additional sensor; receive or obtain statistical data regarding
range of motion norms for people of different ages; receive or
obtain stored user profile data for the current user of the
compatible exercise machine; perform a plurality of analyses of the
user's range of motion; create a profile of the user's range of
motion relative to statistical norms, prior history, and the
virtual reality or mixed reality environment associated with the
user's exercise; display the results to the user in graphical or
textual form; and a balance trainer, comprising at least a
plurality of programming instructions stored in the memory of, and
operating on at least one processor of, a computing device, wherein
the plurality of programming instructions, when operating on the
processor, cause the computing device to: receive data from the
first sensor; calculate, based on the data from the first sensor
and the rate of change of that data, when the user is likely to
stumble or fall; and display a warning to the user in graphical or
textual form to train the user to learn to anticipate and correct
stumbles and falls.
[0007] A method for range of motion analysis and balance training
while exercising has been devised, comprising the steps of:
detecting and characterizing the angle of a user's torso away from
vertical position, using a sensor and exercise machine; detecting
and characterizing the range of motion of at least one portion of a
user's body, using an additional sensor and an exercise machine;
receiving or obtaining statistical data regarding range of motion
norms for people of different ages, using a range of motion
analyzer; receiving or obtaining stored user profile data for the
current user of the compatible exercise machine, using a range of
motion analyzer; performing a plurality of analyses of the user's
range of motion, using a range of motion analyzer; creating a
profile of the user's range of motion relative to statistical
norms, prior history, and the virtual reality or mixed reality
environment associated with the user's exercise, using a range of
motion analyzer; displaying the results to the user in graphical or
textual form; informing a user if they are likely to fall, based at
least in part on data from the first sensor and the rate of change
of that data, using a balance trainer and a first sensor; and
displaying a warning to a user in graphical or textual form in
order to improve a user's ability to anticipate and correct
stumbles or falls through improved exercise form, using a balance
trainer and display.

[0041] Conceptual Architecture
[0042] FIG. 1 is a side view of a variable-resistance exercise
machine with wireless communication for smart device control and
interactive software applications 100, according to a preferred
embodiment of the invention. According to the embodiment, an
exercise machine 100 may have a stable base 101 to provide a
platform for a user to safely stand or move about upon.
[0043] Additional safety may be provided through the use of a
plurality of integrally-formed or detachable side rails 102, for
example having safety rails on the left and right sides (with
respect to a user's point of view) of exercise machine 100 to
provide a stable surface for a user to grasp as needed.
Additionally, side rails 102 may comprise a plurality of open
regions 105a-n formed to provide additional locations for a user to
grasp or for the attachment of additional equipment such as a
user's smart device (not shown) through the use of a mountable or
clamping case or mount. Formed or removable supports 106a-n may be
used for additional grip or mounting locations, for example to
affix a plurality of tethers (not shown) for use in interaction
with software applications while a user is using exercise machine
100 (as described below, referring to FIG. 3).
[0044] Exercise machine 100 may further comprise a rigid handlebar
103 affixed or integrally-formed on one end of exercise machine
100, for a user to hold onto while facing forward during use.
Handlebar 103 may further comprise a stand or mount 104 for a
user's smart device such as (for example) a smartphone or tablet
computer, so they may safely support and stow the device during use
while keeping it readily accessible for interaction (for example,
to configure or interact with a software application they are
using, or to select different applications, or to control media
playback during use, or other various uses). Handlebar 103 may be
used to provide a stable handle for a user to hold onto during use
for safety or stability, as well as providing a rigid point for the
user to "push off" during use as needed, for example to begin using
a moving treadmill surface (described below in FIG. 2). During use,
a user may also face away from handlebar 103, using exercise
machine 100 in the reverse without their view or range of motion
being obscured or obstructed by handlebar 103 (for example, for use
with a virtual reality game that requires a wide degree of movement
from the user's hands for interaction).
[0045] As illustrated, the base 101 of exercise machine 100 may be
formed with a mild, symmetrical curvature, to better approximate
the natural range of movement of a user's body during use. Common
exercise machines such as treadmills generally employ a flat
surface, which can be uncomfortably during prolonged or vigorous
use, and may cause complications with multi-directional movement or
interaction while a user's view is obscured, as with a headset
(described below in FIG. 3). By incorporating a gradual curvature,
a user's movements may feel more natural and require less
reorientation or accommodation to become fluid and proficient, and
stress to the body may be reduced.
[0046] FIG. 3 is a diagram illustrating an exemplary system for a
virtual reality or mixed reality enhanced exercise machine 100 with
wireless communication for smart device control and interactive
software applications using a smart device, illustrating the use of
a plurality of connected smart devices and tethers, and showing
interaction via the user's body as a control stick. According to
the embodiment, a user 301 may be standing, walking, or running on
a variable-resistance exercise machine 100 with wireless
communication for smart device control and virtual reality
applications with a stable base 101 and two separate moveable
surfaces 203a, 203b for separate movement of the user's legs.
Exercise machine 100 may have fixed handlebars with affixed or
integrally-formed controllers 305a, 305b for use as connected smart
devices for interaction, and support rails 201a, 201b for a user to
hold onto or affix tethers for safety or interaction when needed.
User 401 may interact with software applications using a variety of
means, including manual interaction via controller devices 305a,
305b that may be held in the hand for example to use as
motion-input control devices or (as illustrated) may be affixed or
integrally-formed into exercise machine 100. This may provide a
user with traditional means of interacting with software
applications while using exercise machine 100. Additionally, a
user's body position or movement may be tracked and used as input,
for example via a plurality of tethers 304a-n affixed to handlebars
201a, 201b and a belt, harness or saddle 303 worn by user 301, or
using a headset device 302 that may track the position or movement
of a user's head as well as provide video (and optionally audio)
output to the user, such as a virtual reality headset that displays
images while blocking the user's view of the outside world, or an
augmented reality or mixed reality headset that combines presented
information with the user's view using transparent or
semitransparent displays (for example, using transparent OLED
displays, hologram displays, projected displays, or other various
forms of overlaying a display within a user's normal field of
vision without obstructing the user's view). Body tracking may be
used to recognize additional input data from user 301 (in addition
to manual input via controllers 305a, 305b), by tracking the
position and movement of user 301 during use. For example, motion
tracking within a headset device 302 may be used to recognize a
variety of translational 310 or rotational 320 movement of user's
301 head, such as leaning to the side, or looking over the
shoulder. Tethers 304a-n may recognize a variety of movement of
user's 301 torso, such as leaning, crouching, sidestepping, or
other body movement. This body tracking may then be utilized either
as feedback to rehab programs (for example, to track a user's
posture for physical therapy coaching or exercises such as holding
yoga poses) or input similar to a control stick or joystick in
manual controller arrangements, for example by interpreting the
user's entire body as the "stick" and processing their body
movements as if they were stick movements done manually (such as to
control in-game character posture or movement, or to direct
movement in certain applications such as vehicle simulations that
may turn or accelerate in response to stick movements).
[0047] For example, a user 301 on exercise machine 100 may be
playing a virtual reality skiing game or rehab program wherein they
are given audio and video output via a headset 302 to immerse them
in a virtual ski resort. When user 301 is not skiing, they may be
able to use manual controls 305a, 305b for such operations as
selecting from an on-screen menu, or typing text input such as to
input their name or to chat with other players using text. When
they begin skiing within the game, user 301 may be instructed in
proper ski posture or technique, and may then use their body to
control various aspects of their virtual skiing, such as leaning to
the side 320 to alter their course and avoid trees or other skiers,
or jumping 310 to clear rocks or gaps. Movement of their head may
be detected by a headset 302 and used to control their view
independently of their body as it is tracked by tethers 304a-n,
allowing user 301 to look around freely without interfering with
their other controls. In this manner, the user's entire body may
serve as an input control device for the game, allowing and
encouraging them to use natural body movements to control their
gameplay in an immersive manner while still retaining the option to
use more familiar manual control means as needed. Alternatively,
specific body functions such as hip twisting are used as user
feedback for rehabilitating programs, including rehab games.
[0048] FIG. 12 is a diagram illustrating an exemplary system 1200
for a virtual reality or mixed reality enhanced exercise machine
100, illustrating the use of a plurality of optical sensors to
detect body movement of a user during use of an exercise machine.
As above (with reference to FIG. 3), a user 301 may be standing,
walking or running, sitting, or otherwise physically active during
use of an exercise machine 100. During use, the user's position,
posture, movement, cadence, technique, or any other movement or
position-related information may be detected, observed, or measured
using a plurality of body movement sensors such as (for example,
including but not limited to) tethers 304a-n that may optionally be
affixed to handlebars 201a-b or other features of an exercise
machine 100, hardware sensors integrated into controllers 305a-b or
a headset 302 the user may be using during exercise for virtual
reality or mixed reality applications, or using a plurality of
optical sensors 1201a-n that may be affixed to an exercise machine
100 or adjacent equipment, or that may be affixed to or positioned
within an environment around exercise machine 100 to observe the
user 301 during use. Optical sensors 1201a-n may be used in a
variety of configurations or arrangements, such as using a single
wide-angle sensor positioned to observe a user's movement or
posture from a particular angle (which may be useful for coaching
or physical therapy applications), or using more than one sensor
placed about a user to observe their movement in three-dimensional
space. A variety of hardware may be utilized in optical sensors
1201a-n, for example including (but not limited to) an infrared or
other optical camera that may directly observe the user's movement,
a structured-light emitter that projects a structured-light grid
1202 or other arrangement onto the user, exercise machine, or
environment (and corresponding scanner or receiver that may observe
the user's movement through detected changes in the
structured-light projection), or a light-field sensor that detects
or measures depth to observe a user's movement in three-dimensions.
It should also be appreciated that various combination of optical
sensors 1201a-n may be utilized to achieve a desired effect, for
example using both structured light and a light-field sensor to
observe a user's movement in precise detail in three dimensions.
Additionally, some or all optical sensors 1201a-n utilized in some
arrangements may be integrated into a user's headset 302 or an
exercise machine 100 to provide "inside-out" tracking where
tracking sensors are associated with the user rather than the
environment, or they may be external devices as illustrated that
may be introduced to enhance an existing exercise machine or
environment.
[0049] Utilizing an exercise machine 100 in this manner allows for
a variety of novel forms of user interaction within virtual reality
or mixed reality applications. For example, a user's body movement
during exercise may be tracked in three dimensions and along or
around various axes to record movement with six degrees of freedom
(6DOF) comprising both translation along, and rotation about, each
of three spatial axes. This may be used with torso tracking as
described above (referring to FIGS. 3-7) to produce a 6DOF "torso
joystick" virtual device that directs movement or other inputs
within a software application. This may be used in a number of
ways, for example including but not limited to aiding exercise
through interactive coaching (either with a human coach or using
software to simulate a coach by providing feedback to detected user
movements), providing physical therapy, interacting with games or
other applications during exercise, or using exercise combined with
software interaction for an immersive virtual reality or mixed
reality experience. For example, a user may control movement or
expression of a virtual avatar or other user representation within
a software application, such as using their own body movements to
direct movement of a virtual character. Physical therapy or fitness
coaching may utilize detected movements to assist a user with
improving their abilities or technique, or to measure progress.
Social interaction applications may utilize body movements during
exercise, for example a chat or voice call application may utilize
body movement as a form of nonverbal expression similar to emoji or
other icons. Safety may also be enhanced by controlling the
operation of software in response to detected user movements, for
example displaying caution information or pausing an application if
a user is detected to move outside a configured safety parameter
(such as stepping off a running treadmill, for example).
[0050] FIG. 8 is a block diagram of an exemplary system
architecture 800 for natural body interaction for mixed or virtual
reality applications, according to a preferred embodiment of the
invention. According to the embodiment, a composition server 801
comprising programming instructions stored in a memory 11 and
operating on a processor 12 of a computing device 10 (as described
below, with reference to FIG. 13), may be configured to receive a
plurality of input data from various connected devices. Such input
devices may include (but are not limited to) a variety of hardware
controller devices 804 (such as a gaming controller [such as GOJI
PLAY.TM. controllers], motion tracking controller, or traditional
computer input devices such as a keyboard or mouse), a headset
device 803 such as an augmented reality or mixed or virtual reality
headset (for example, OCULUS RIFT.TM., HTC VIVE.TM., SAMSUNG GEAR
VR.TM., MICROSOFT MIXED REALITY.TM., or other headset devices), a
variety of fitness devices 805 (for example, fitness tracking
wearable devices such as FITBIT.TM., MICROSOFT BAND.TM., APPLE
WATCH.TM., or other wearable devices), or a variety of body input
802 tracking devices or arrangements, such as using a plurality of
tethers attached to the environment and a harness worn by a user,
configured to track movement and position of the user's body.
[0051] Various input devices may be connected to composition server
801 interchangeably as desired for a particular arrangement or use
case, for example a user may wish to use a controller 804 in each
hand and a headset 803, but omit the use of fitness devices 805
altogether. During operation, composition server 801 may identify
connected devices and load any stored configuration corresponding
to a particular device or device type, for example using
preconfigured parameters for use as a default configuration for a
new controller, or using historical configuration for a headset
based on previous configuration or use. For example, a user may be
prompted (or may volunteer) to provide configuration data for a
particular device, such as by selecting from a list of options (for
example, "choose which type of device this is", or "where are you
wearing/holding this device", or other multiple-choice type
selection), or composition server 801 may employ machine learning
to automatically determine or update device configuration as
needed. For example, during use, input values may be received that
are determined to be "out of bounds", for example an erroneous
sensor reading that might indicate that a user has dramatically
shifted position in a way that should be impossible (for example,
an erroneous reading that appears to indicate the user has moved
across the room and back again within a fraction of a second, or
has fallen through the floor, or other data anomalies). These data
values may be discarded, and configuration updated to reduce the
frequency of such errors in the future, increasing the reliability
of input data through use.
[0052] Composition server 801 may receive a wide variety of input
data from various connected devices, and by comparing against
configuration data may discard undesirable or erroneous readings as
well as analyze received input data to determine more complex or
fine-grained measurements. For example, combining input from
motion-sensing controllers 804 with a motion-sensing headset 803
may reveal information about how a user is moving their arms
relative to their head or face, such as covering their face to
shield against a bright light or an attack (within a game, for
example), which might otherwise be impossible to determine with any
reliability using only the controllers themselves (as it may be
observed that a user is raising their hands easily enough, but
there is no reference for the position or movement of their head).
These derived input values may then be combined into a single
composite input data stream for use by various software
applications, such as augmented reality or mixed or virtual reality
productivity applications (for example, applications that assist a
user in performing manual tasks by presenting virtual information
overlays onto their field of vision, or by playing audio directions
to instruct them while observing their behavior through input
devices, or other such applications), or mixed or virtual reality
applications or games, such as simulation games that translate a
user's movement or position into in-game interaction, for example
by moving a user's in-game character or avatar based on their
physical movements as received from input devices. In some
arrangements, composition server 801 may operate such software
applications in a standalone manner, functioning as a computer or
gaming console as needed. In other arrangements, composition server
801 may provide the composite data for use by an external computer
810, such as a connected gaming console, mixed or virtual reality
device, personal computer, or a server operating via a network in
the cloud (such as for online gaming arrangements, for example). In
this manner, the composite data functions of the embodiment may be
utilized with existing hardware if desired, or may be provided in a
standalone package such as for demonstrations or public use, or for
convenient setup using a single device to provide the full
interaction experience (in a manner similar to a household gaming
console, wherein all the functions of computer components may be
prepackaged and setup to minimize difficulty for a new user).
[0053] It should be appreciated that while reference is made to
virtual reality applications, a wide variety of use cases may be
possible according to the embodiment. For example, torso tracking
may be used for fitness and health applications, to monitor a
user's posture or gait while walking, without the use of additional
virtual reality equipment or software. In some arrangements, some
or all interaction between a user and a software application may be
nonvisual, and in some arrangements no display device may be
present. In such an arrangement, a user may interact with software
entirely using feedback and movement of a worn harness 420 or
tethers 304a-n, using resistance or software-guided actuation of
tethers 304a-n (as described below, with reference to FIGS. 4-7) or
other elements. In other arrangements, various combinations of
display devices and other electronic devices may be used for a
mixed-reality setup, for example where a user's movement and
interaction may be used by software to incorporate elements of the
physical world into a digital representation of the user or
environment. For example, a user may interact with games or fitness
applications, participate in social media such as chat, calls,
online discussion boards, social network postings, or other social
content, or they may use body tracking to navigate user interface
elements of software such as a web browser or media player.
Software used in this manner may not need to be
specially-configured to utilize body tracking, for example to
navigate a web browser a user's body movements or reactions to
feedback may be processed by a composition server 801 and mapped to
generic inputs such as keystrokes or mouse clicks, for use in any
standard software application without the need for special
configuration.
[0054] It should be further appreciated that while reference is
made to a treadmill-type exercise machine 100, such an exercise
machine is exemplary and any of a number of exercise machines may
be utilized according to the aspects disclosed herein, for example
including (but not limited to) a treadmill, a stationary bicycle,
an elliptical machine, a rowing machine, or even non-electronic
exercise equipment such as a pull-up bar or weight machine.
Traditional exercise equipment may be outfitted with additional
components to facilitate virtual reality or mixed reality
interaction according to the aspects disclosed herein, for example
by affixing a plurality of tethers 304a-n to a weight machine so
that a user's movement during exercise may be used as interaction
as described below (with reference to FIGS. 3-7).
Detailed Description of Exemplary Embodiments
[0055] FIG. 2 is a top-down view of a variable-resistance exercise
machine 100 with wireless communication for smart device control
and interactive software applications, according to a preferred
embodiment of the invention. According to the embodiment, exercise
machine 100 may comprise a stable base 101 to provide a platform
for a user to safely stand or move about upon. Exercise machine 100
may further comprise right 201a and left 201b hand rails for a user
to brace against or grip during use, to provide a stable support
for safety as well as a mounting point for external devices such as
a plurality of tethers, as described below with reference to FIG.
3. A plurality of steps 202a-n may be used to provide a user with a
safe and easy means to approach or dismount exercise machine 100,
as well as a nonmoving "staging area" where a user may stand while
they configure operation or wait for exercise machine 100 to start
operation. Unlike traditional treadmill machines common in the art,
exercise machine 100 may be made with greater width to accommodate
a wider range of free movement of a user's entire body (whereas
traditional treadmills are designed to best accommodate only a
jogging or running posture, with minimal lateral motion), and a
plurality of separate moving surfaces 203a-b may be utilized to
provide multiple separate surfaces that may move and be controlled
independently of one another during use. For example, a user may
move each of their legs independently without resistance applied,
with separate moving surfaces 203a-b moving freely underfoot as a
user applies pressure during their movement. This may provide the
illusion of movement to a user while in reality they remain
stationary with respect to their surroundings. Another use may be
multiple separate moving surfaces 203a-b, with separate speeds of
movement or degrees of resistance, so that as a user moves about
during use they may experience physical feedback in the form of
changing speed or resistance, indicating where they are standing or
in what direction they are moving (for example, to orient a user
wearing a virtual reality headset, as described below with
reference to FIG. 3). Moving surfaces 203a-b may be formed with a
texture 204 to increase traction, which may improve user safety and
stability during use as well as improve the operation of moving
surfaces 203a-b for use in multidirectional movement (as the user's
foot is less likely to slide across a surface rather than taking
purchase and applying directional pressure to produce movement).
Use of multiple, multidirectional moving surfaces 203a-b may also
be used in various therapeutic or rehabilitation roles, for example
to aid a user in developing balance or range of motion. For
example, a user who is recovering from an injury or surgery (such
as a joint repair or replacement surgery) may require regular
physical therapy during recovery. Use of multidirectional moving
surfaces 203a-b along with appropriate guidance from a
rehabilitation specialist or physical therapist (or optionally a
virtual or remote coach using a software application) may make
regular therapy more convenient and accessible to the user, rather
than requiring in-home care or regular visits to a clinic. For
example, by enabling a therapist or coach to manually vary the
movement and resistance of the moving surfaces 203a-b, they can
examine a user's ability to overcome resistance to different
movements such as at odd angles or across varying range of motion,
to examine the user's physical health or ability. By further
varying the resistance it becomes possible to assist the user with
rehabilitation by providing targeted resistance training to
specific movements, positions, or muscle groups to assist in
recovery and development of the user's abilities.
[0056] Exercise machine 100 may be designed without a control
interface commonly utilized by exercise machines in the art,
instead being configured with any of a variety of wireless network
interfaces such as Wi-Fi or BLUETOOTH.TM. for connection to a
user's smart device, such as a smartphone or tablet computer. When
connected, a user may use a software application on their device to
configure or direct the operation of exercise machine 100, for
example by manually configuring a variety of operation settings
such as speed or resistance, or by interacting with a software
application that automatically directs the operation of exercise
machine 100 without exposing the particular details of operation to
a user. Additionally, communication may be bi-directional, with a
smart device directing the operation of exercise machine 100 and
with exercise machine 100 providing input to a smart device based
at least in part on a user's activity or interaction. For example,
a user may interact with a game on their smart device, which
directs the operation of exercise machine 100 during play as a form
of interaction with, and feedback to, the user. For example, in a
racing game, exercise machine 100 may alter the resistance of
moving surfaces 203a-b as a user's speed changes within the game.
In another example, a user may be moving about on moving surfaces
203a-b while playing a simulation or roleplaying game, and their
movement may be provided to the connected smart device for use in
controlling an in-game character's movement. Another example may be
two-way interactive media control, wherein a user may select media
such as music for listening on their smart device, and then while
using exercise machine 100 their level of exertion (for example,
the speed at which they run or jog) may be used to provide input to
their smart device for controlling the playback of media. For
example, if the user slows down music may be played slowly,
distorting the audio unless the user increases their pace. In this
manner, exercise machine 100 may be used interchangeably as a
control and feedback device or both simultaneously, providing an
immersive environment for a wide variety of software applications
such as virtual reality, video games, fitness and health
applications, or interactive media consumption.
[0057] FIG. 4 is a diagram of an exemplary hardware arrangement 400
for natural torso tracking and feedback for electronic interaction
according to a preferred embodiment of the invention, illustrating
the use of multiple tethers 410a-n and a movable torso harness 420.
According to the embodiment, a plurality of tethers 410a-n may be
affixed or integrally-formed as part of a handle or railing 430,
such as handlebars found on exercise equipment such as a treadmill,
elliptical trainer, stair-climbing machine, or the like. In
alternate arrangements, specifically-designed equipment with
integral tethers 410a-n may be used, but it may be appreciated that
a modular design with tethers 410a-n that may be affixed and
removed freely may be desirable for facilitating use with a variety
of fitness equipment or structural elements of a building,
according to a user's particular use case or circumstance. Tethers
410a-n may then be affixed or integrally-formed to a torso harness
420, as illustrated in the form of a belt, that may be worn by a
user such that movement of their body affects tethers 410a-n and
applies stress to them in a variety of manners. It should be
appreciated that while a belt design for a torso harness 420 is
shown for clarity, a variety of physical arrangements may be used
such as including (but not limited to) a vest, a series of
harness-like straps similar to climbing or rappelling equipment, a
backpack, straps designed to be worn on a user's body underneath or
in place of clothing (for example, for use in medical settings for
collecting precise data) or a plurality of specially-formed clips
or attachment points that may be readily affixed to a user's
clothing. Additionally, a torso harness 420 may be constructed with
movable parts, for example having an inner belt 421 that permits a
user some degree of motion within the harness 420 without
restricting their movement. Movement of inner belt 421 (or other
movable portions) may be measured in a variety of ways, such as
using accelerometers, gyroscopes, or optical sensors, and this data
may be used as interaction with software applications in addition
to data collected from tethers 410a-n as described below. In some
embodiments, a saddle-like surface on which a user may sit may be
used, with motion of the saddle-like surface measured as described
generally herein.
[0058] As a user moves, his or her body naturally shifts position
and orientation. These shifts may be detected and measured via
tethers 410a-n, for example by detecting patterns of tension or
strain on tethers 410a-n to indicate body orientation, or by
measuring small changes in strain on tethers 410a-n to determine
more precise movements such as body posture while a user is
speaking, or specific characteristics of a user's stride or gait.
Additionally, through varying the quantity and arrangement of
tethers 410a-n, more precise or specialized forms of movement may
be detected and measured (such as, for example, using a specific
arrangement of multiple tethers connected to a particular area of a
user's body to detect extremely small movements for medical
diagnosis or fitness coaching). This data may be used as
interaction with software applications, such as for virtual reality
applications as input for a user to control a character in a game.
In such an arrangement, when a user moves, this movement may be
translated to an in-game character or avatar to convey a more
natural sense of interaction and presence. For example, in a
multiplayer roleplaying game, this may be used to facilitate
nonverbal communication and recognition between players, as their
distinct mannerisms and gestures may be conveyed in the game
through detection of natural torso position and movement. In
fitness or health applications, this data may be used to track and
monitor a user's posture or ergonomic qualities, or to assist in
coaching them for specific fitness activities such as holding a
pose for yoga, stretching, or proper running form during use with a
treadmill. In medical applications, this data may be used to assist
in diagnosing injuries or deficiencies that may require attention,
such as by detecting anomalies in movement or physiological
adaptations to an unrecognized injury (such as when a user
subconsciously shifts their weight off an injured foot or knee,
without consciously realizing an issue is present).
[0059] Through various arrangements of tethers 410a-n and tether
sensors (as described below, referring to FIGS. 5-7), it may be
possible to enable a variety of immersive ways for a user to
interact with software applications, as well as to receive haptic
feedback from applications. For example, by detecting rotation,
tension, stress, or angle of tethers a user may interact with
applications such as virtual reality games or simulations, by using
natural body movements and positioning such as leaning, jumping,
crouching, kneeling, turning, or shifting their weight in various
directions to trigger actions within a software application
configured to accept torso tracking input. By applying haptic
feedback of varying form and intensity (as is described in greater
detail below, referring to FIG. 5), applications may provide
physical indication to a user of software events, such as applying
tension to resist movement, pulling or tugging on a tether to move
or "jerk" a user in a direction, or varying feedback to multiple
tethers such as tugging and releasing in varying order or sequence
to simulate more complex effects such as (for example, in a gaming
use case) explosions, riding in a vehicle, or walking through
foliage.
[0060] FIG. 5 is a diagram illustrating a variety of alternate
tether arrangements. According to various use cases and hardware
arrangements, tethers 410a-n may utilize a variety of
purpose-driven designs as illustrated. For example, a "stretchable"
tether 510 may be used to measure strain during a user's movement,
as the tether 510 is stretched or compressed (for example, using
piezoelectric materials and measuring electrical changes). Such an
arrangement may be suitable for precise measurements, but may lack
the mechanical strength or durability for gross movement detection
or prolonged use. An alternate construction may utilize a
non-deforming tether 520 such as a steel cable or similar
non-stretching material. Instead of measuring strain on the tether
520, instead tether 520 may be permitted a degree of movement
within an enclosure 522 (for example, an attachment point on a
torso harness 420 or handlebar 430), and the position or movement
521 of the tether 520 may be measured such as via optical sensors.
In a third exemplary arrangement, a tether 530 may be wound about
an axle or pulley 531, and may be let out when force is applied
during a user's movement. Rotation of the pulley 531 may be
measured, or alternately a tension device such as a coil spring may
be utilized (not shown) and the tension or strain on that device
may be measured as tether 530 is extended or retracted. In this
manner, it may be appreciated that a variety of mechanical means
may be used to facilitate tethers and attachments for use in
detecting and measuring natural torso position and movement, and it
should be appreciated that a variety of additional or alternate
hardware arrangements may be utilized according to the embodiments
disclosed herein.
[0061] Additionally, through the use of various hardware
construction it becomes possible to utilize both "passive" tethers
that merely measure movement or strain, as well as "active" tethers
that may apply resistance or movement to provide haptic feedback to
a user. For example, in an arrangement utilizing a coiled spring or
pulley 531, the spring or pulley 531 may be wound to retract a
tether and direct or impede a user's movement as desired. In this
manner, various new forms of feedback-based interaction become
possible, and in virtual reality use cases user engagement and
immersion are increased through more natural physical feedback
during their interaction.
[0062] By applying various forms and intensities of feedback using
various tether arrangements, a variety of feedback types may be
used to provide haptic output to a user in response to software
events. For example, tension on a tether may be used to simulate
restrained movement such as wading through water or dense foliage,
walking up an inclined surface, magnetic or gravitational forces,
or other forms of physical resistance or impedance that may be
simulated through directional or non-directional tension. Tugging,
retracting, or pulling on a tether may be used to simulate sudden
forces such as recoil from gunfire, explosions, being grabbed or
struck by a software entity such as an object or character,
deploying a parachute, bungee jumping, sliding or falling, or other
momentary forces or events that may be conveyed with a tugging or
pulling sensation. By utilizing various patterns of haptic
feedback, more complex events may be communicated to a user, such
as riding on horseback or in a vehicle, standing on the deck of a
ship at sea, turbulence in an aircraft, weather, or other virtual
events that may be represented using haptic feedback. In this
manner, virtual environments and events may be made more immersive
and tangible for a user, both by enabling a user to interact using
natural body movements and positioning, as well as by providing
haptic feedback in a manner that feels natural and expected to the
user. For example, if a user is controlling a character in a gaming
application through a first-person viewpoint, it would seem natural
that when their character is struck there would be a physical
sensation corresponding to the event; however, this is not possible
with traditional interaction devices, detracting from any sense of
immersion or realism for the user. By providing this physical
sensation alongside the virtual event, the experience becomes more
engaging and users are encouraged to interact more naturally as
their actions results in natural and believable feedback, meeting
their subconscious expectations and avoiding excessive
"immersion-breaking" moments, which in turn reduces the likelihood
of users adopting unusual behaviors or unhealthy posture as a
result of adapting to limited interaction schema.
[0063] Haptic feedback may be provided to notify a user of
non-gaming events, such as for desktop notifications for email or
application updates, or to provide feedback on their posture for
use in fitness or health coaching. For example, a user may be
encouraged to maintain a particular stance, pose, or posture while
working or for a set length of time (for example, for a yoga
exercise application), and if their posture deviates from an
acceptable range, feedback is provided to remind them to adjust
their posture. This may be used in sports, fitness, health, or
ergonomic applications that need not utilize other aspects of
virtual reality and may operate as traditional software
applications on nonspecialized computing hardware. For example, a
user at their desk may use an ergonomic training application that
monitors their body posture throughout the work day and provides
haptic reminders to correct poor posture as it is detected, helping
the user to maintain a healthy working posture to reduce fatigue or
injuries due to poor posture (for example, repetitive-stress
injuries that may be linked to poor posture while working at a
computer).
[0064] FIG. 6 is a diagram of an additional exemplary hardware
arrangement 600 for natural torso tracking and feedback for
electronic interaction according to a preferred embodiment of the
invention, illustrating the use of angle sensors 612, 621a-n to
detect angled movement of a tether 620. According to one exemplary
arrangement, a tether 610 may be affixed to or passed through a
rotating joint such as a ball bearing 611 or similar, to permit
free angular movement. During movement, the angular movement or
deflection 612 of a protruding bar, rod, or tether segment 613 may
be measured (for example, using optical, magnetic, or other
sensors) to determine the corresponding angle of tether 610. In
this manner, precise angle measurements may be collected without
impeding range of motion or introducing unnecessary mechanical
complexity.
[0065] In an alternate hardware arrangement, the use of angle
sensors 621a-n enables tracking of a vertical angle of a tether
620, to detect and optionally measure vertical movement or
orientation of a user's torso. When tether 620 contacts a sensor
621a-n, this may be registered and used to detect a general
vertical movement (that is, whether the tether is angled up or
down). For more precise measurements, the specific hardware
construction of a sensor 621a-n may be varied, for example using a
pressure-sensing switch to detect how much force is applied and use
this measurement to determine the corresponding angle (as may be
possible given a tether 620 of known construction). It should be
appreciated that various combinations of hardware may be used to
provide a desired method or degree of angle detection or
measurement, for example using a conductive tether 620 and a
capacitive sensor 621a-n to detect contact, or using a mechanical
or rubber-dome switch (as are commonly used in keyboard
construction) to detect physical contact without a conductive
tether 620.
[0066] The use of angle detection or measurement may expand
interaction possibilities to encompass more detailed and natural
movements of a user's body. For example, if a user crouches, then
all tethers 410a-n may detect a downward angle simultaneously.
Additionally, data precision or availability may be enhanced by
combining input from multiple available sensors when possible (for
example, utilizing adaptive software to collect data from any
sensors that it detects, without requiring specific sensor types
for operation), for example by combining data from tethers 410a-n
and hardware sensors such as an accelerometer or gyroscope,
enabling multiple methods of achieving similar or varied types or
precision levels of position or movement detection. Similarly, when
a user jumps then all tethers may detect an upward angle
simultaneously. However, if a user leans in one direction, it may
be appreciated that not all tethers 410a-n will detect the same
angle. For example, tethers 410a-n in the direction the user is
leaning may detect a downward angle, while those on the opposite
side would detect an upward angle (due to the orientation of the
user's torso and thus a worn torso harness 420). In this manner,
more precise torso interaction may be facilitated through improved
detection and recognition of orientation and movement.
Additionally, it may be appreciated that sensors 621a-n may be
utilized for other angle measurements, such as to detect horizontal
angle. For example, if a user is wearing a non-rotating torso
harness 420, when they twist their body a similar stress may be
applied to all attached tethers 410a-n. Without angle detection the
precise nature of this movement will be vague, but with horizontal
angle detection it becomes possible to recognize that all tethers
410a-n are being strained in a similar direction (for example, in a
clockwise pattern when viewed from above, as a user might view
tethers 410a-n during use), and therefore interpret the interaction
as a twisting motion (rather than, for example, a user squatting or
kneeling, which might apply a similar stress to the tethers 410a-n
but would have different angle measurements).
[0067] FIG. 7 is a diagram illustrating an exemplary hardware
arrangement of an apparatus for natural torso tracking and feedback
for electronic interaction according to a preferred embodiment of
the invention, illustrating the use of multiple tethers 410a-n and
a movable torso harness 420 comprising a plurality of angle sensors
701a-n positioned within the movable torso harness 420. According
to the embodiment, a plurality of tethers 410a-n may be affixed or
integrally-formed as part of a handle or railing 430, such as
handlebars found on exercise equipment such as a treadmill,
elliptical trainer, stair-climbing machine, or the like. In
alternate arrangements, specifically-designed equipment with
affixed or integral tethers 410a-n may be used, but it may be
appreciated that a modular design with tethers 410a-n that may be
affixed and removed freely may be desirable for facilitating use
with a variety of fitness equipment or structural elements of a
building, according to a user's particular use case or circumstance
as well as weight-holding strength of the tethers. Tethers 410a-n
may then be affixed or integrally-formed to angle sensors 701a-n
placed within or integrally-formed as a component of torso harness
420 (as illustrated in the form of a belt) that may be worn by a
user such that movement of their body affects tethers 410a-n and
applies detectable or measurable stress to tethers 410a-n and
angular motion to angle sensors 701a-n. In this manner, it may be
appreciated that angle sensors 701a-n may be utilized as integral
or removable components of a torso harness 420, as an alternative
arrangement to utilizing angle sensors 701a-n placed or formed
within railings 430 or other equipment components connected to
distal ends of tethers 410a-n (with respect to the user's torso).
According to various embodiments, sensors may be placed optionally
on a belt, vest, harness, or saddle-like surface or at attachment
points on safety railings, or indeed both.
[0068] FIG. 9 is a block diagram of an exemplary system
architecture 900 of an exercise machine 100 being connected over
local connections to a smartphone or computing device 930, an
output device other than a phone 910, and a server over a network
940, according to a preferred aspect. An exercise machine 100 may
connect over a network 920, which may be the Internet, a local area
connection, or some other network used for digital communication
between devices, to a server 940. Such connection may allow for
two-way communication between a server 940 and an exercise machine
800. An exercise machine 100 may also be connected over a network
920 to a smartphone or computing device 930, or may be connected
directly to a smartphone or computing device 930 either physically
or wirelessly such as with Bluetooth connections. An exercise
machine 100 also may be connected to an output device 910 which may
display graphical output from software executed on an exercise
machine 100, including Mixed or virtual reality software, and this
device may be different from a smartphone or computing device 930
or in some implementations may in fact be a smartphone or computing
device 930. A remote server 940 may contain a data store 941, and a
user verification component 942, which may contain typical
components in the art used for verifying a user's identity from a
phone connection or device connection, such as device ID from a
smartphone or computing device or logging in with a user's social
media account.
[0069] FIG. 10 is a diagram of an exemplary hardware arrangement of
a smart phone or computing device 1030 executing software 1010 and
communicating over a network 1020, according to a preferred aspect.
In an exemplary smart phone or computing device 1030, key
components include a wireless network interface 1031, which may
allow connection to one or a variety of wireless networks including
Wi-Fi and Bluetooth; a processor 1032, which is capable of
communicating with other physical hardware components in the
computing device 1030 and running instructions and software as
needed; system memory 1033, which stores temporary instructions or
data in volatile physical memory for recall by the system processor
1032 during software execution; and a display device 1034, such as
a Liquid Crystal Display (LCD) screen or similar, with which a user
may visually comprehend what the computing device 1030 is doing and
how to interact with it. It may or may not be a touch enabled
display, and there may be more components in a computing device
1030, beyond what are crucially necessary to operate such a device
at all. Software 1010 operating on a processor 1033 may include a
mixed or virtual reality application, a user verification system,
or other software which may communicate with a network-enabled
server 1040 and exercise machine 100 software for the purposes of
enhanced mixed or virtual reality.
[0070] FIG. 11 is a block diagram of a method of mixed or virtual
reality software operating to receive input through different
sources, and send output to devices, according to a preferred
aspect. Mixed or virtual reality software which may be run on a
phone or computing device 1030 or another device, outputs data to a
visual device for the purpose of graphically showing a user what
they are doing in the software 1110. Such display may be a phone
display 1034, or a separate display device such as a screen built
into an exercise machine 100 or connected some other way to the
system, or both display devices. During software execution, user
input may be received either through buttons 1130 on the exercise
machine 100, 1120, or through input from a belt-like harness 420,
such as user orientation or movements. Such received data may be
sent 1140 to either a mobile smart phone or computing device 1030,
or to a server 1040 over a network 1020, or both, for processing,
storage, or both. Data may be stored on a server with a data store
device 1041 and may be processed for numerous uses including user
verification with a user verification component 1042. Data may be
processed either by software running on an exercise machine 100, a
smart phone or computing device 1030, or some other connected
device which may be running mixed or virtual reality software, when
input is received from a user using either buttons on an exercise
machine 100, a belt-like harness 420, or both, and optionally using
hardware features of an exercise machine 100 such as handlebars,
pedals, or other features in mixed or virtual reality software for
tasks such as representing movement in a simulation.
[0071] FIG. 17 is a block diagram of an exemplary virtual reality
or mixed reality enhanced exercise machine, illustrating the use of
a stationary bicycle 1700 with hand controls on the handles 1720,
and a belt-like harness attachment 420. A stationary exercise
bicycle device 1700, which may be of any particular design
including a reclining, sitting, or even unicycle-like design,
possesses two pedals 1730 as is common for stationary exercise
bicycles of all designs. On handlebars of a stationary exercise
bicycle may exist buttons and controls 1720 for interacting with a
virtual reality or mixed reality augmented piece of software,
allowing a user to press buttons in addition to or instead of
pedaling, to interact with the software. A belt-like harness
attachment 420 is attached via a mechanical arm 1710 to a
stationary exercise bicycle 1700, which may monitor motion and
movements from a user during the execution of virtual reality
software. A mechanical arm 1710 may have an outer shell composed of
any material, the composition of which is not claimed, but must
have hinges 1711, 1712, 1713 which allow for dynamic movement in
any position a user may find themselves in, and angular sensors
inside of the arm at the hinge-points 1711, 1712, 1713 for
measuring the movement in the joints and therefore movement of the
user. A stationary bicycle device 1700 may also have a pressure
sensor in a seat 1740, the sensor itself being of no particularly
novel design necessarily, to measure pressure from a user and
placement of said pressure, to detect movements such as leaning or
sitting lop-sided rather than sitting evenly on the seat.
[0072] FIG. 18 is a diagram of another exemplary virtual reality or
mixed reality enhanced exercise machine, illustrating the use of a
treadmill exercise machine 100, 1800 a vest-type harness 1820 with
a plurality of pistons 1811 to provide a hardware-based torso
joystick with full-body tracking. According to this embodiment, a
treadmill or other exercise machine 100, 1800 may comprise a
plurality of rigid side tails 102 for a user to grip for support as
needed during use (for example, as a balance aid or to assist
getting on the machine and setting up other equipment properly) as
well as a rigid stand or mount 104 for a user's smartphone or other
computing device, that may be used to operate a virtual reality or
mixed reality software application. Exercise machine 100, 1800 may
further comprise a jointed arm 1810 or similar assembly that may be
integrally-formed or removably affixed to or installed upon
exercise machine 100, 1800. Arm 1810 may utilize a plurality of
pistons 1811 to provide for movement during use in order to follow
the movement's of a user's body, as well as to provide tension or
resistance to motion when appropriate (for example, to resist a
user's movements or to provide feedback) and motion detection of a
user's movement during use, according to various aspects described
previously (referring to FIGS. 3-7, for example) by measuring
movement of a piston 1811 or arm 1810 and optionally applying
tension or resistance to piston 1811 to retard movement of arm 1810
and constrain user movement or simulate specific forms of physical
feedback. For example, if a user is moving an avatar in a virtual
reality software application, when the avatar encounters an
obstacle such as another avatar, object, or part of the
environment, resistance may be applied to piston 1811 to prevent
the user from moving further, so that their avatar is effectively
prevented from moving through the obstacle and thereby facilitating
the immersive experience of a solid object in a virtual
environment. Additional arms may be used for a user's limbs 1921
and may incorporate straps 1922 to be affix about a user's arm,
wrist, or other body part, to incorporate more detailed movement
tracking of a user's arms and/or legs rather than just torso-based
tracking. A vest-type harness 1920 may be used in place of a belt
420, to allow for more natural movement or to provide greater area
upon which to affix additional arms 1821, pistons 1811, or any of a
variety of sensors, for example such as accelerometers 1822 or
gyroscopes 1823 for detecting body orientation (not all optional
sensors are shown for the sake of clarity). For example, a vest
1820 may have integrated feedback actuators 1812 for use in
first-person software applications to simulate impacts or recoil,
or it may incorporate heating or cooling elements to simulate
different virtual environments while worn. Additionally, vest 1820
may incorporate electrical connectors 1824 for various peripheral
devices such as controllers 305a-b or a headset 302, reducing the
risk of tangles or injury by keeping cables short and close to the
user so they cannot cause issues during movement or exercise.
[0073] FIG. 19 is a diagram of another exemplary virtual reality or
mixed reality enhanced exercise machine, illustrating the use of a
stationary bicycle This present application is a
continuation-in-part of Ser. No. 16/176,511, titled "VIRTUAL
REALITY AND MIXED REALITY ENHANCED EXERCISE MACHINE", and filed on
Oct. 31, 2018, which with a vest-type harness 1820 with a plurality
of strain sensors 1911 and tethers 1912, according to an aspect of
the invention. According to this embodiment, rather than a jointed
arm 1810 and pistons 1811, a solid flexible arm 1910 may be used to
detect user movement while positioned on a seat 1902 to use
exercise machine 100, for example while the user is seated to use
pedals 1901 on a stationary bike or elliptical training machine.
Through a plurality of strain gauges 1911 that detect the flexion
or extension of the solid arm. Tethers 1912 may be used for either
movement tracking or providing feedback to a user, or both, and may
optionally be connected or routed through joints or interconnects
1913 to allow for a greater variety of attachment options as well
more precise feedback (for example, by enabling multiple angles
from which a tether 1912 may apply force, to precisely simulate
different effects). Additional arms may be used for a user's limbs
1921 and may incorporate straps 1922 to be affix about a user's
arm, wrist, or other body part, to incorporate more detailed
movement tracking of a user's arms and/or legs rather than just
torso-based tracking. Additional arms 1921 may also incorporate
additional tethers 1912 and strain sensors 1911 to track movement
and apply feedback to specific body parts during use, further
increasing precision and user immersion. A vest-type harness 1820
may be used in place of a belt 420, to allow for more natural
movement or to provide greater area upon which to affix additional
arms 1921, tether 1912, or any of a variety of sensors, for example
such as accelerometers or gyroscopes for detecting body orientation
(not all optional sensors are shown for the sake of clarity). For
example, a vest 1820 may have integrated feedback actuators for use
in first-person software applications to simulate impacts or
recoil, or it may incorporate heating or cooling elements to
simulate different virtual environments while worn. Additionally,
vest 1820 may incorporate electrical connectors 1914 for various
peripheral devices such as controllers 305a-b or a headset 302,
reducing the risk of tangles or injury by keeping cables short and
close to the user so they cannot cause issues during movement or
exercise.
[0074] FIG. 20 is a flow diagram illustrating an exemplary method
2000 for operating a virtual and mixed-reality enhanced exercise
machine, according to one aspect. According to the aspect, a user
may wear 2001 a torso harness such as a belt 420 or vest 1820
harness, while they engage in the use 2002 of an exercise machine
100. While using the exercise machine 100, the user's movements may
be detected and measured 2003 through the use of a plurality of
body movement sensors such as (for example, including but not
limited to) strain sensors 1911, tethers 410a-c, 1912, pistons
1811, or optical sensors 1201a-n. These measured user movements may
then be mapped by a composition server 801 to correspond to a
plurality of movement inputs of a virtual joystick device 2004.
These virtual joystick inputs may then be transmitted 2005 to a
software application, for example a virtual reality or mixed
reality application operating on a user device such as (for
example, including but not limited to) a smartphone 930, personal
computing device, or headset 302. Composition server 801 may then
receive feedback from the software application 2006, and may direct
the operation of a plurality of feedback devices such as tethers
410a-c, 1912 or pistons 1811 to resist or direct the user's
movement 2007 to provide physical feedback to the user based on the
received software feedback.
[0075] FIG. 21 is a system diagram of a key components in the
analysis of a user's range of motion and balance training,
according to a preferred embodiment. A datastore containing
statistical data 2110 on a user's age category, gender, and other
demographic data, as well as a datastore containing balancing
algorithms 2120, are connected to a collection of components
integrated into an exercise system 2130, including a plurality of
sensors 2131, a movement profile generator 2132, a balance trainer
2133, and a tuner 2134. A plurality of sensors 2131 may be
connected to varying parts of an exercise system, tethered to a
user, or otherwise connected to or able to sense a user during
exercise, and may inform a movement profile generator 2132 of the
performance of a user's exercise during such exercise. A movement
profile generator 2132 may use data from a datastore containing
statistical data on a user 2110 to generate movement profile of how
a user performs and moves during exercise, in comparison with how
they may be expected to move, and pass this data on to a balance
trainer 2133 which is further connected to a datastore containing
balance algorithms 2120. A balance trainer 2133 accesses and
utilizes balance algorithms 2120 in conjunction with assembled
movement profile data 2132 and determines if a user is in need of
correcting their form or balance during exercise. A tuner 2134 is
connected to a datastore containing user profile data 2150 and also
connected to a balance tuner 2133, enabling a user's individual
preferences or specifications, or exercise needs, to inform
adjustments for a balance trainer 2133, for example if a user would
initially be detected as stumbling by a balance trainer 2133 but
the user were to specify that they are not falling, and continue to
exercise in this fashion for whatever reason (such as physical
limitations), a tuner 2134 may adjust the balance trainer 2133 in
this instance. Such information is stored in a user's profile data
2150. A display 2140 is connected to core components 2130 and may
display the warnings generated by a balance trainer 2133 or offer a
user the opportunity to offer adjustments or physical information
to a tuner 2134 for adjusting a balance trainer 2133.
[0076] FIG. 22 is a system diagram of a user moving during
exercise, in a form analogous to an inverted pendulum, according to
a preferred aspect. A user 2210 may be wearing a sensor 2131,
either on their torso, leg, or some other part of their body, and
move their body over an angle from vertical position 2220. Angular
momentum 2230 may be represented by .theta.'' 2230, a user's angle
deviation from vertical being represented by .theta. 2220, the
gravitational constant of Earth being represented by g 2240, and
the approximate height of a user's body-part acting similar to the
bar of an inverted pendulum being represented by L 2250. Using
these symbols, an equation of the form .theta.''=(g/L)sin .theta.
may be used in conjunction with a sensor 2131 which may contain an
accelerometer, gyroscope, or both, in order to characterize the
angle .theta. 2220 and angular acceleration .theta.'' 2230 of a
user 2210 as they perform an exercise. It is therefore possible to
analyze and characterize a user's motions that may lead to a
stumble or fall.
[0077] FIG. 23 is a system diagram of a sensor measuring the range
of motion of a user during a specific exercise, according to a
preferred aspect. A user performing an exercise with their leg is
shown, with a sensor 2131 and angular movement 2310. A sensor 2131
may be used to characterize the angle of the user's motion, or be
attached as an ankle weight for a more specific implementation (but
by no means the only implementation of this process of using a
sensor to measure an individual user's body parts during exercise),
to achieve more information about user form in addition to or
instead of using an inverted pendulum 2220 with a sensor 2131
inside, according to a preferred aspect.
[0078] FIG. 24 is a method diagram illustrating behavior and
performance of key components for range of motion analysis and
balance training, according to a preferred aspect. A user's
movements may first be detected on or with an exercise machine,
using a plurality of sensors 2131, 2410. Given a user's movements
2410, statistical data on a user's demographics may be gathered
2420 using a datastore containing such information 2110, to compare
a user's movements with expected or anticipated norms based on
acquired or default statistical data. A user's profile data 2150
may then be accessed 2430, and using a user's profile data 2150
which may contain individual preferences or information beyond
statistical norms 2110 or sensor-acquired exercise data 2131,
analyses of a user's range of motion may occur 2440. Such analyses
may include examining differences between a user's expected motion
during an exercise, with their actual motion, measuring individual,
anomalous movements during a user's exercise (such as a single
motion that does not match with the rest of the user's movements),
and other techniques to analyze anomalies in a user's displayed
exercise ability. A user's profile is also generated from these
analyses 2440, allowing a history of a user's exercise performance
to be recorded for future analysis and for comparison with future
observed exercise patterns and performance. A user's profile and
exercise performance, along with any other notes, may be displayed
2450 with a graphical or textual display 2140, allowing a user to
see for themselves their performance and deficiencies as determined
by the system. A further step may be to detect if a user is detect
to be likely to fall or stumble 2460, such as if a leg movement is
not proper for a running motion on a treadmill, and display or
sound a warning to a user 2470 using a display 2140 or any other
method that may be available to the exercise device for warning a
user of possible injury or failure. These warnings may further be
recorded in a user profile 2150 for access by a tuner 2134 and
balance trainer 2133 to help the user be aware of patterns of
exercise performance that may lead to similar incidents in the
future, before they happen, thereby helping to ensure safety of
physically at-risk exercise machine users.
Hardware Architecture
[0079] Generally, the techniques disclosed herein may be
implemented on hardware or a combination of software and hardware.
For example, they may be implemented in an operating system kernel,
in a separate user process, in a library package bound into network
applications, on a specially constructed machine, on an
application-specific integrated circuit (ASIC), or on a network
interface card.
[0080] Software/hardware hybrid implementations of at least some of
the embodiments disclosed herein may be implemented on a
programmable network-resident machine (which should be understood
to include intermittently connected network-aware machines)
selectively activated or reconfigured by a computer program stored
in memory. Such network devices may have multiple network
interfaces that may be configured or designed to utilize different
types of network communication protocols. A general architecture
for some of these machines may be described herein in order to
illustrate one or more exemplary means by which a given unit of
functionality may be implemented. According to specific
embodiments, at least some of the features or functionalities of
the various embodiments disclosed herein may be implemented on one
or more general-purpose computers associated with one or more
networks, such as for example an end-user computer system, a client
computer, a network server or other server system, a mobile
computing device (e.g., tablet computing device, mobile phone,
smartphone, laptop, or other appropriate computing device), a
consumer electronic device, a music player, or any other suitable
electronic device, router, switch, or other suitable device, or any
combination thereof. In at least some embodiments, at least some of
the features or functionalities of the various embodiments
disclosed herein may be implemented in one or more virtualized
computing environments (e.g., network computing clouds, virtual
machines hosted on one or more physical computing machines, or
other appropriate virtual environments).
[0081] Referring now to FIG. 13, there is shown a block diagram
depicting an exemplary computing device 10 suitable for
implementing at least a portion of the features or functionalities
disclosed herein. Computing device 10 may be, for example, any one
of the computing machines listed in the previous paragraph, or
indeed any other electronic device capable of executing software-
or hardware-based instructions according to one or more programs
stored in memory. Computing device 10 may be configured to
communicate with a plurality of other computing devices, such as
clients or servers, over communications networks such as a wide
area network a metropolitan area network, a local area network, a
wireless network, the Internet, or any other network, using known
protocols for such communication, whether wireless or wired.
[0082] In one embodiment, computing device 10 includes one or more
central processing units (CPU) 12, one or more interfaces 15, and
one or more busses 14 (such as a peripheral component interconnect
(PCI) bus). When acting under the control of appropriate software
or firmware, CPU 12 may be responsible for implementing specific
functions associated with the functions of a specifically
configured computing device or machine. For example, in at least
one embodiment, a computing device 10 may be configured or designed
to function as a server system utilizing CPU 12, local memory 11
and/or remote memory 16, and interface(s) 15. In at least one
embodiment, CPU 12 may be caused to perform one or more of the
different types of functions and/or operations under the control of
software modules or components, which for example, may include an
operating system and any appropriate applications software,
drivers, and the like.
[0083] CPU 12 may include one or more processors 13 such as, for
example, a processor from one of the Intel, ARM, Qualcomm, and AMD
families of microprocessors. In some embodiments, processors 13 may
include specially designed hardware such as application-specific
integrated circuits (ASICs), electrically erasable programmable
read-only memories (EEPROMs), field-programmable gate arrays
(FPGAs), and so forth, for controlling operations of computing
device 10. In a specific embodiment, a local memory 11 (such as
non-volatile random access memory (RAM) and/or read-only memory
(ROM), including for example one or more levels of cached memory)
may also form part of CPU 12. However, there are many different
ways in which memory may be coupled to system 10. Memory 11 may be
used for a variety of purposes such as, for example, caching and/or
storing data, programming instructions, and the like. It should be
further appreciated that CPU 12 may be one of a variety of
system-on-a-chip (SOC) type hardware that may include additional
hardware such as memory or graphics processing chips, such as a
QUALCOMM SNAPDRAGON.TM. or SAMSUNG EXYNOS.TM. CPU as are becoming
increasingly common in the art, such as for use in mobile devices
or integrated devices.
[0084] As used herein, the term "processor" is not limited merely
to those integrated circuits referred to in the art as a processor,
a mobile processor, or a microprocessor, but broadly refers to a
microcontroller, a microcomputer, a programmable logic controller,
an application-specific integrated circuit, and any other
programmable circuit.
[0085] In one embodiment, interfaces 15 are provided as network
interface cards (NICs). Generally, NICs control the sending and
receiving of data packets over a computer network; other types of
interfaces 15 may for example support other peripherals used with
computing device 10. Among the interfaces that may be provided are
Ethernet interfaces, frame relay interfaces, cable interfaces, DSL
interfaces, token ring interfaces, graphics interfaces, and the
like. In addition, various types of interfaces may be provided such
as, for example, universal serial bus (USB), Serial, Ethernet,
FIREWIRE.TM., THUNDERBOLT.TM., PCI, parallel, radio frequency (RF),
BLUETOOTH.TM., near-field communications (e.g., using near-field
magnetics), 802.11 (WiFi), frame relay, TCP/IP, ISDN, fast Ethernet
interfaces, Gigabit Ethernet interfaces, Serial ATA (SATA) or
external SATA (ESATA) interfaces, high-definition multimedia
interface (HDMI), digital visual interface (DVI), analog or digital
audio interfaces, asynchronous transfer mode (ATM) interfaces,
high-speed serial interface (HSSI) interfaces, Point of Sale (POS)
interfaces, fiber data distributed interfaces (FDDIs), and the
like. Generally, such interfaces 15 may include physical ports
appropriate for communication with appropriate media. In some
cases, they may also include an independent processor (such as a
dedicated audio or video processor, as is common in the art for
high-fidelity AN hardware interfaces) and, in some instances,
volatile and/or non-volatile memory (e.g., RAM).
[0086] Although the system shown in FIG. 13 illustrates one
specific architecture for a computing device 10 for implementing
one or more of the inventions described herein, it is by no means
the only device architecture on which at least a portion of the
features and techniques described herein may be implemented. For
example, architectures having one or any number of processors 13
may be used, and such processors 13 may be present in a single
device or distributed among any number of devices. In one
embodiment, a single processor 13 handles communications as well as
routing computations, while in other embodiments a separate
dedicated communications processor may be provided. In various
embodiments, different types of features or functionalities may be
implemented in a system according to the invention that includes a
client device (such as a tablet device or smartphone running client
software) and server systems (such as a server system described in
more detail below).
[0087] Regardless of network device configuration, the system of
the present invention may employ one or more memories or memory
modules (such as, for example, remote memory block 16 and local
memory 11) configured to store data, program instructions for the
general-purpose network operations, or other information relating
to the functionality of the embodiments described herein (or any
combinations of the above). Program instructions may control
execution of or comprise an operating system and/or one or more
applications, for example. Memory 16 or memories 11, 16 may also be
configured to store data structures, configuration data, encryption
data, historical system operations information, or any other
specific or generic non-program information described herein.
[0088] Because such information and program instructions may be
employed to implement one or more systems or methods described
herein, at least some network device embodiments may include
nontransitory machine-readable storage media, which, for example,
may be configured or designed to store program instructions, state
information, and the like for performing various operations
described herein. Examples of such nontransitory machine-readable
storage media include, but are not limited to, magnetic media such
as hard disks, floppy disks, and magnetic tape; optical media such
as CD-ROM disks; magneto-optical media such as optical disks, and
hardware devices that are specially configured to store and perform
program instructions, such as read-only memory devices (ROM), flash
memory (as is common in mobile devices and integrated systems),
solid state drives (SSD) and "hybrid SSD" storage drives that may
combine physical components of solid state and hard disk drives in
a single hardware device (as are becoming increasingly common in
the art with regard to personal computers), memristor memory,
random access memory (RAM), and the like. It should be appreciated
that such storage means may be integral and non-removable (such as
RAM hardware modules that may be soldered onto a motherboard or
otherwise integrated into an electronic device), or they may be
removable such as swappable flash memory modules (such as "thumb
drives" or other removable media designed for rapidly exchanging
physical storage devices), "hot-swappable" hard disk drives or
solid state drives, removable optical storage discs, or other such
removable media, and that such integral and removable storage media
may be utilized interchangeably. Examples of program instructions
include both object code, such as may be produced by a compiler,
machine code, such as may be produced by an assembler or a linker,
byte code, such as may be generated by for example a JAVA.TM.
compiler and may be executed using a Java virtual machine or
equivalent, or files containing higher level code that may be
executed by the computer using an interpreter (for example, scripts
written in Python, Perl, Ruby, Groovy, or any other scripting
language).
[0089] In some embodiments, systems according to the present
invention may be implemented on a standalone computing system.
Referring now to FIG. 14, there is shown a block diagram depicting
a typical exemplary architecture of one or more embodiments or
components thereof on a standalone computing system. Computing
device 20 includes processors 21 that may run software that carry
out one or more functions or applications of embodiments of the
invention, such as for example a client application 24. Processors
21 may carry out computing instructions under control of an
operating system 22 such as, for example, a version of MICROSOFT
WINDOWS.TM. operating system, APPLE MACOS.TM. or iOS.TM. operating
systems, some variety of the Linux operating system, ANDROID.TM.
operating system, or the like. In many cases, one or more shared
services 23 may be operable in system 20, and may be useful for
providing common services to client applications 24. Services 23
may for example be WINDOWS.TM. services, user-space common services
in a Linux environment, or any other type of common service
architecture used with operating system 21. Input devices 28 may be
of any type suitable for receiving user input, including for
example a keyboard, touchscreen, microphone (for example, for voice
input), mouse, touchpad, trackball, or any combination thereof.
Output devices 27 may be of any type suitable for providing output
to one or more users, whether remote or local to system 20, and may
include for example one or more screens for visual output,
speakers, printers, or any combination thereof. Memory 25 may be
random-access memory having any structure and architecture known in
the art, for use by processors 21, for example to run software.
Storage devices 26 may be any magnetic, optical, mechanical,
memristor, or electrical storage device for storage of data in
digital form (such as those described above, referring to FIG. 13).
Examples of storage devices 26 include flash memory, magnetic hard
drive, CD-ROM, and/or the like.
[0090] In some embodiments, systems of the present invention may be
implemented on a distributed computing network, such as one having
any number of clients and/or servers. Referring now to FIG. 15,
there is shown a block diagram depicting an exemplary architecture
30 for implementing at least a portion of a system according to an
embodiment of the invention on a distributed computing network.
According to the embodiment, any number of clients 33 may be
provided. Each client 33 may run software for implementing
client-side portions of the present invention; clients may comprise
a system 20 such as that illustrated in FIG. 14. In addition, any
number of servers 32 may be provided for handling requests received
from one or more clients 33. Clients 33 and servers 32 may
communicate with one another via one or more electronic networks
31, which may be in various embodiments any of the Internet, a wide
area network, a mobile telephony network (such as CDMA or GSM
cellular networks), a wireless network (such as WiFi, WiMAX, LTE,
and so forth), or a local area network (or indeed any network
topology known in the art; the invention does not prefer any one
network topology over any other). Networks 31 may be implemented
using any known network protocols, including for example wired
and/or wireless protocols.
[0091] In addition, in some embodiments, servers 32 may call
external services 37 when needed to obtain additional information,
or to refer to additional data concerning a particular call.
Communications with external services 37 may take place, for
example, via one or more networks 31. In various embodiments,
external services 37 may comprise web-enabled services or
functionality related to or installed on the hardware device
itself. For example, in an embodiment where client applications 24
are implemented on a smartphone or other electronic device, client
applications 24 may obtain information stored in a server system 32
in the cloud or on an external service 37 deployed on one or more
of a particular enterprise's or user's premises.
[0092] In some embodiments of the invention, clients 33 or servers
32 (or both) may make use of one or more specialized services or
appliances that may be deployed locally or remotely across one or
more networks 31. For example, one or more databases 34 may be used
or referred to by one or more embodiments of the invention. It
should be understood by one having ordinary skill in the art that
databases 34 may be arranged in a wide variety of architectures and
using a wide variety of data access and manipulation means. For
example, in various embodiments one or more databases 34 may
comprise a relational database system using a structured query
language (SQL), while others may comprise an alternative data
storage technology such as those referred to in the art as "NoSQL"
(for example, HADOOP CASSANDRA.TM., GOOGLE BIGTABLE.TM., and so
forth). In some embodiments, variant database architectures such as
column-oriented databases, in-memory databases, clustered
databases, distributed databases, or even flat file data
repositories may be used according to the invention. It will be
appreciated by one having ordinary skill in the art that any
combination of known or future database technologies may be used as
appropriate, unless a specific database technology or a specific
arrangement of components is specified for a particular embodiment
herein. Moreover, it should be appreciated that the term "database"
as used herein may refer to a physical database machine, a cluster
of machines acting as a single database system, or a logical
database within an overall database management system. Unless a
specific meaning is specified for a given use of the term
"database", it should be construed to mean any of these senses of
the word, all of which are understood as a plain meaning of the
term "database" by those having ordinary skill in the art.
[0093] Similarly, most embodiments of the invention may make use of
one or more security systems 36 and configuration systems 35.
Security and configuration management are common information
technology (IT) and web functions, and some amount of each are
generally associated with any IT or web systems. It should be
understood by one having ordinary skill in the art that any
configuration or security subsystems known in the art now or in the
future may be used in conjunction with embodiments of the invention
without limitation, unless a specific security 36 or configuration
system 35 or approach is specifically required by the description
of any specific embodiment.
[0094] FIG. 16 shows an exemplary overview of a computer system 40
as may be used in any of the various locations throughout the
system. It is exemplary of any computer that may execute code to
process data. Various modifications and changes may be made to
computer system 40 without departing from the broader scope of the
system and method disclosed herein. Central processor unit (CPU) 41
is connected to bus 42, to which bus is also connected memory 43,
nonvolatile memory 44, display 47, input/output (I/O) unit 48, and
network interface card (NIC) 53. I/O unit 48 may, typically, be
connected to keyboard 49, pointing device 50, hard disk 52, and
real-time clock 51. NIC 53 connects to network 54, which may be the
Internet or a local network, which local network may or may not
have connections to the Internet. Also shown as part of system 40
is power supply unit 45 connected, in this example, to a main
alternating current (AC) supply 46. Not shown are batteries that
could be present, and many other devices and modifications that are
well known but are not applicable to the specific novel functions
of the current system and method disclosed herein. It should be
appreciated that some or all components illustrated may be
combined, such as in various integrated applications, for example
Qualcomm or Samsung system-on-a-chip (SOC) devices, or whenever it
may be appropriate to combine multiple capabilities or functions
into a single hardware device (for instance, in mobile devices such
as smartphones, video game consoles, in-vehicle computer systems
such as navigation or multimedia systems in automobiles, or other
integrated hardware devices).
[0095] In various embodiments, functionality for implementing
systems or methods of the present invention may be distributed
among any number of client and/or server components. For example,
various software modules may be implemented for performing various
functions in connection with the present invention, and such
modules may be variously implemented to run on server and/or client
components.
[0096] The skilled person will be aware of a range of possible
modifications of the various embodiments described above.
Accordingly, the present invention is defined by the claims and
their equivalents.
