Description
RELATED PATENT DOCUMENTS
[0001] This is a divisional of U.S. patent application Ser. No.
10/185,899, filed on Jun. 28, 2002, to which Applicant claims
priority under 35 U.S.C. .sctn.120, and which is incorporated
herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates generally to communication of
user information via a mobile communication device and, more
particularly, to systems and methods for acquiring physiological
sensor data of a user for integration in an avatar representative
of the user with use of a mobile communication device.
BACKGROUND OF THE INVENTION
[0003] Good physical fitness is key to maintaining good health and
fighting disease. Medical evidence has shown that excess body fat,
for example, poses a major threat to health and longevity. Excess
body fat is linked to major physical threats, such as heart
disease, cancer, and diabetes. Consistent exercise is an important
factor in maintaining proper weight and good health.
[0004] Motivation plays a significant role in one's interest in
continuous and productive exercise. Although exercise videos,
programming, and literature abound, many people quickly lose
interest in such short-term motivational tools. Such conventional
exercise enhancements generally fail to provide the requisite
feedback needed to keep an individual motivated in a given exercise
regimen. The inability to provide real-life information concerning
fitness training that associates exercise to physical fitness
results in an easily perceivable manner limits the usefulness of
conventional exercise motivational techniques over the long
term.
[0005] As contemporary lifestyles have become increasingly
fast-paced and complicated, the number of personal electronic
devices carried on the person has increased. It is not uncommon for
an individual to carry a cellular phone, a PDA, some form of
calculator, a pager, and a portable personal medical device, such
as a body fat measuring device, heart rate monitor or pedometer,
for example. The inconvenience of physically transporting and
accounting for such devices often results in eliminating certain
devices from one's personal inventory of devices. In many cases,
personal medical devices, such as heart rate monitoring devices,
which can enhance exercise regimens and provide motivation for
healthier lifestyle habits, are cast aside in favor of more
utilitarian devices, such as the now ubiquitous cellular phone.
[0006] There is a need for integration of mobile communications and
health promoting devices, such as heart rate monitoring devices.
There is a need for improved motivational techniques that allow
individuals to associate real-life physiological data with the
individual's progress toward particular fitness goals. The present
invention addresses these and other needs, and provides additional
features and advantages over conventional implementations and
techniques.
SUMMARY OF THE INVENTION
[0007] The present invention is directed to a system and method for
acquiring physiological sensor data of a user for integration in an
avatar representative of the user with use of a mobile
communication device. According to one embodiment, a method
implemented with use of a mobile communication device and at least
one sensor configured to sense a parameter associated with a user's
physiology involves sensing one or more parameters associated with
the user's physiology, the sensed one or more parameters defining
physiological data associated with the user. The method further
involves analyzing the physiological data relative to training
regimen data, the training regimen data comprising one or both of
range limits and durations associated with an exercise regimen. The
method also involves transferring the physiological data to the
mobile communication device, and providing, by the mobile
communication device, the physiological data in a form suitable for
integration into an avatar representative of the user.
[0008] In accordance with another embodiment, a mobile system
includes a mobile communication device configured to receive
fitness data comprising training regimen data, the training regimen
data comprising one or both of range limits and durations
associated with an exercise regimen. A sensor apparatus is adapted
to contact a user and acquire physiological data when in contact
with the user. Transfer circuitry is configured to communicatively
couple the sensor apparatus and the mobile communication device.
The sensor apparatus is configured to receive the fitness data from
the mobile communication device via the transfer circuitry and
analyze the acquired physiologic data relative to the training
regimen data. The transfer circuitry is further configured to
transfer the acquired physiological data from the sensor apparatus
to the mobile communication device, and the mobile communication
device is configured to provide the physiological data in a form
suitable for integration into an avatar representative of the
user.
[0009] The present invention is further directed to a system and
method of interacting with a virtual physiological model of a user
with use of a mobile communication device. According to one
methodology of the present invention, physiological data associated
with the user is acquired from the user. The physiological data is
transmitted to the mobile communication device, preferably with use
of a wireless communication protocol. The methodology further
involves using the mobile communication device to communicate the
physiological data to a network server. The physiological data is
integrated into a virtual physiological model of the user.
[0010] The acquired physiological data can include one or more of
the user's weight, caloric consumption, blood pressure of the user,
information concerning the user's diet, and anatomical measurements
of the user, for example. A number of physical characteristics of
the user can be developed using the physiological data of the
virtual physiological model. Such physical characteristics of the
user can include one or more of muscle mass, percent body fat,
anatomical dimensions, energy consumption, stress level, heart rate
characteristics, and rate of recovery from an exercise regimen, for
example.
[0011] In accordance with another embodiment, a method of
interacting with a virtual physiological model of a user involves
acquiring physiological data associated with the user and
transmitting the physiological data to a network server using the
mobile communication device. The physiological data is integrated
into the virtual physiological model of the user. Fitness data is
generated using physiological data associated with the virtual
physiological model of the user. The fitness data is communicated
to the user.
[0012] The fitness data can include heart rate data associated with
a specified period of time, a rate at which the user recovers from
an exercise regimen, a mapping of heart rate data to each of a
number of physiological data states or user depictions developed
from the virtual physiological model. The fitness data can also
include stress level data associated with the user and one or both
of percent body fat data and muscle mass of the user.
[0013] Communicating fitness data to the user can involve
communicating a depiction of the user based on the physiological
data associated with the virtual physiological model of the user.
Changes to the user's depiction can be effected in response to
changes to the physiological data associated with the virtual
physiological model of the user. For example, changes to one or
more anatomical dimensions of the user can be depicted. The
depiction of the user can include one or both of graphical and
textual information based on the physiological data associated with
the virtual physiological model of the user.
[0014] Historical physiological data of the virtual physiological
model can be analyzed to predict changes in the fitness data over
time. For example, historical physiological data of the virtual
physiological model can be analyzed to predict changes in the
fitness data in response to a set of input data applied to the
virtual physiological model of the user. The set of input data can
include a set of current physiological data acquired from the user
or a set of test physiological data input by the user.
[0015] According to another embodiment of the present invention, a
mobile physiological information system includes a mobile
communication device and a physiological sensor device adapted for
acquiring physiological data associated with the user. The system
further includes a transfer device communicatively coupled to the
physiological sensor device and the mobile communication device.
The transfer device transmits the physiological data to the mobile
communication device for subsequent integration into a virtual
physiological model of the user.
[0016] In accordance with another embodiment of the present
invention, a mobile physiological information system communicates
with a network and a network server. The system includes a fitness
data engine operable at the network server, a mobile communication
device, and a physiological sensor device adapted for acquiring
physiological data associated with the user. The system further
includes a transfer device communicatively coupled to the
physiological sensor device and the mobile communication device.
The transfer device transmits the physiological data to the mobile
communication device, and the mobile communication device
communicates the physiological data to the fitness data engine. The
fitness data engine integrates the physiological data into a
virtual physiological model of the user and generates fitness data
using physiological data associated with the virtual physiological
model of the user for subsequent transmission to the user.
[0017] The above summary of the present invention is not intended
to describe each embodiment or every implementation of the present
invention. Advantages and attainments, together with a more
complete understanding of the invention, will become apparent and
appreciated by referring to the following detailed description and
claims taken in conjunction with the accompanying drawings.

[0025] While the invention is amenable to various modifications and
alternative forms, specifics thereof have been shown by way of
example in the drawings and will be described in detail. It is to
be understood, however, that the intention is not to limit the
invention to the particular embodiments described. On the contrary,
the intention is to cover all modifications, equivalents, and
alternatives falling within the scope of the invention as defined
by the appended claims.
DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS
[0026] In the following description of the illustrated embodiments,
reference is made to the accompanying drawings which form a part
hereof, and in which is shown by way of illustration, various
embodiments in which the invention may be practiced. It is to be
understood that the embodiments may be utilized and structural
changes may be made without departing from the scope of the present
invention.
[0027] The present invention is directed to systems and methods for
using mobile communication techniques to enhance an understanding
of the physiological state of an individual based on physiological
information acquired from the individual in real-time. The
principles of the present invention find particular applicability
in the context of development, refinement, and monitoring of
physical fitness regimens and training, and verification of the
effectiveness of such regimens and training over time.
[0028] Systems and methods of the present invention provide for the
generation of, and maintenance and modification to, a virtual
physiological model, referred to herein as an avatar, of an
individual. The virtual physiological model, in general,
characterizes the physiological state of an individual based on
physical statistics of the individual (e.g., weight, height,
gender, and age) and physiological data acquired from the user in
real-time.
[0029] Employment of a visual depiction or characterization of a
user's real-time physiological state in accordance with the
principles of the present invention provides a comprehensive visual
physical fitness feedback methodology heretofore unavailable using
conventional physiological monitoring techniques. The integration
of multiple sources of real-life physiological data for a given
user enables a much more accurate characterization, and, therefore,
understanding, of the user's state of physical fitness in real-time
and the effects of various training regimens undertaken by the
user.
[0030] As such, exercise and training regimens can be developed and
augmented over time to facilitate achievement of particular
physical fitness goals of a given user. The accuracy by which the
impact of fitness training of a user is measured can be
significantly improved by employment of the systems and method of
the present invention. Further, by presenting the impact of fitness
training in the form of an avatar, which provides a unique,
entertaining, and real-life characterization of the user's physical
state of being, a user is motivated to remain committed to improved
physical fitness.
[0031] Physiological data is preferably acquired from the user
through use of non-invasive techniques. Various types of
physiological data can be acquired from the user, including, in
particular, heart rate data. Blood pressure data can be acquired
from time to time and incorporated into the virtual physiological
model of the user. Body temperature, particularly when measured
during extended periods of exertion, can also be acquired. Oxygen
saturation and oxygen consumption can also be measured and
incorporated into the user's virtual physiological model. Further,
percent body fat can be determined and incorporated into the user's
virtual physiological model. Various other physiological parameters
can be acquired or developed for incorporation into the user's
avatar.
[0032] In addition, the virtual physiological model of the user
incorporates various information about the user's stature, age,
gender, weight, anatomical dimensions, and diet. For example the
model can incorporate the dimensions of the various parts of the
user's anatomy, such as waist, arms, legs, torso, and neck
dimensions, for example. The diet of the user, which can include a
percentage and caloric consumption of fats and carbohydrates, for
example, can be incorporated as data associated with the
avatar.
[0033] Physiological data is preferably acquired in real-time
throughout each day. The rate of sampling or recording of a user's
physiological data can be constant or, more preferably, varied
depending on a number of factors, such as time of day and activity
level of the user. For example, the rate, amount, and/or variety of
physiological data acquired from the user preferably increases
during periods of increased activity, such as during exercise,
training, and periods of elevated stress, and decreases during
periods of decreased activity, such as during sleep.
[0034] The acquired physiological data is used to generate various
types of fitness data. In one form, the fitness data can include
various types of physiological parameters, and changes to such
parameters over time, computed using the user's acquired
physiological data, such as average heart rate during exercise,
recovery rates from exertion, stress level, caloric consumption,
muscle mass, percent body fat, and oxygen consumption during
exertion. In another form, the fitness data can include graphical
or animation data, in which physical attributes of the user are
visually depicted in the form of an avatar. Changes to the avatar
can be effected in response to changes in the user's acquired
physiological data over time, to predictions based on historical
physiological data, and to predictions based on test physiological
data and/or training regimen parameters.
[0035] By way of example, a user can create an avatar
representative of the current physical state of the user. The user
can adjust the avatar to change the appearance of the avatar to a
more desired appearance. For example, the anatomical dimensions of
the avatar can be changed to reflect desired waist, chest, upper
arms, and thigh dimensions, for example. Given differences between
the desired avatar features and present avatar features, various
training, diet, and related fitness recommendations can be
developed to establish a training regimen(s) most suited to helping
the user achieve the desired fitness goals. Physiological data is
subsequently acquired and applied to the user's avatar, and
compared to the desired avatar's data, to determine if the training
regimen is effective in achieving the desired fitness goals.
Further alterations in the training regimen and/or diet can be
made, the effects of which can be monitored by subsequent
acquisition of the user's physiological data.
[0036] Turning now to the drawings, and more particularly to FIG.
1, there is illustrated a system 120 for acquiring physiological
data from a user and communicating the physiological data via a
mobile terminal to a network server for integration into a virtual
physiological model established for the user in accordance with an
embodiment of the present invention. FIG. 1 shows a physiological
sensor device 130 communicatively coupled to a mobile terminal 122.
The physiological sensor device 130 is intended to represent one or
more sensing devices that sense one or more physiological
parameters of a user, such as heart rate, for example. The
physiological sensor device 130 is communicatively coupled to
mobile terminal 122 via a wireless link, such as wireless link that
conforms to the Bluetooth wireless specification. In another
configuration, the physiological sensor device 130 can be coupled
to the mobile terminal 122 via a hard wired connection, although it
is perceived that a wireless link is more desirable in most
cases.
[0037] The physiological sensor device 130 acquires physiological
data (PD) from the user and transmits this data to the mobile
terminal 122. According to one approach, the mobile terminal 122
effectively functions as a modem by communicating the physiological
data received from the physiological sensor device 130 to a radio
network 124, such as a 2G or 3G network. It is noted that the
network 124 shown in the figures can alternatively be
representative of an IP or Mobil IP network, such as an IPv4, IPv6,
or hybrid IPv4/IPv6 network for example.
[0038] According to another approach, the mobile terminal 122
cooperates with the physiological sensor device 130 to buffer
physiological data received from the physiological sensor device
130, noting that portions of the physiological data acquired by the
physiological sensor device 130 in real-time can be stored/buffered
in memory of one or both of the mobile terminal 122 and
physiological sensor device 130. This cooperative use of
distributed memory is of particular use when significant amounts of
real-time physiological data obtained by several sensors are
acquired, and in situations where a communication link between the
mobile terminal 122 and network 124 cannot be established or is
unstable/unreliable.
[0039] The physiological data communicated from the mobile terminal
122 to the network 124 is routed to a server 126 which is
configured to accept and process this data. The server 126 stores
and executes processing software that, in general, operates on the
physiological data received from each of a number of users. The
processing software integrates currently or recently acquired
physiological data into the user's virtual physiological model
(i.e., avatar). The user can review the data associated with his or
her avatar using the mobile terminal 122 or other user
access/display device 128.
[0040] The server 126 also provides for the creation of a
user-specific avatar by each of a number of users, and further
provides for interaction between users and their respective
avatars. It can be appreciated that the information associated with
a user's avatar is highly personal in nature. As such, access to a
user's avatar and information associated with the avatar is
typically subject to tight access restrictions. For example, access
rights to a user's avatar and related information are typically
granted only to the user, who can typically grant access rights at
various security levels to others as desired.
[0041] The processing software further computes fitness data (FD)
of various types, including, textual, graphical, animation, audio,
video, or other form of fitness data. As previously discussed, the
fitness data can include various types of physiological parameters,
changes to such parameters over time, training and diet
recommendations, and various views of the user's avatar, among
other forms of data. The fitness data is communicated from the
server 126 to the user via the network 124. The fitness data can be
communicated to the mobile terminal 122 or some other user
access/display device 128.
[0042] According to one implementation, the mobile terminal 122 can
receive the fitness data in the form of a training regime and
upload this fitness data to the physiological sensor device 130.
The training regimen, according to this illustrative example, can
include a sequence of programmable heart rate range limits and
durations associated with a given exercise routine. The programmed
sequence can provide upper and lower heart rate limits for each
period defining the routine, in which an alarm is activated if the
user's recommended heart rate falls outside of an applicable heart
rate range for a given exercise period. In another implementation,
it may be desirable to view the user's avatar on a display coupled
to the physiological sensor device 130, rather than on the display
of the mobile terminal 122. This may be the case where the subject
physiological sensor device 130 is implemented as a table-top
system, rather than a portable or ambulatory device.
[0043] FIG. 2A is a depiction of a system for acquiring
physiological data from a user and communicating the physiological
data via a mobile terminal to a network server for integration into
a virtual physiological model established for the user in
accordance with another embodiment of the present invention.
According to this embodiment, a number of different physiological
sensor devices can be employed to acquire a variety of different
physiological parameters from a user. As shown in the illustrative
embodiment of FIG. 2A, a system of the present invention can
include a variety of physiological sensor devices, including
portable or ambulatory sensor devices, table-top or stationary
sensor devices, and a combination of these devices. The
physiological sensor devices are preferably non-invasive devices.
It is understood that a system of the present invention can range
in sophistication from simple configurations, in which one or
perhaps two physiological sensor devices are employed, to complex
configurations, in which several physiological sensor devices are
employed.
[0044] Each of the physiological sensor devices includes an
integral transfer device 203 which facilitates the transmission of
acquired physiological data to a mobile terminal 122. According to
this embodiment, the transfer device 203 includes a communication
device configured to operate in conformance with the Bluetooth
wireless specification. The mobile terminal 122 also has the
capability to communicate with the transfer device 203 in
conformance with the Bluetooth wireless specification. The transfer
device 203 can be configured to provide for unidirectional or
bi-directional communication with the mobile terminal 122.
[0045] As discussed previously, physiological data, such as heart
rate data, can be acquired and transmitted to the mobile terminal
122 via the transfer device 203 in real-time. Alternatively,
physiological data can be buffered in memory of one or both of the
physiological sensor device and mobile terminal 122. In a real-time
mode of operation, the mobile terminal 122 operates effectively as
a modem to facilitated the transfer of acquired physiological data
between the physiological sensor device, mobile terminal 122,
network 124, and server 126 in real-time.
[0046] A fitness data engine 220 supported by the server 126 can
receive the acquired physiological data in real-time, interact with
the user's avatar, such as by integrating the acquired
physiological data into the avatar, generate fitness data,
including various processed data and avatar depictions, and
transmit the fitness data to the mobile terminal 122 or other user
access/display device in real-time. It is understood that these
data can also be transmitted between the various communication
elements on a non real-time basis.
[0047] The mobile terminal 122 includes a display 212 and user
interface 216, among other standard components. The user interface
216 of the mobile terminal 122 can be used to input various types
of user related information needed to create, modify, or otherwise
interact with the user's avatar residing on the server 126. For
example, the user can input weight, height, age, gender, and other
physical and personal information to the user's virtual
physiological model via the mobile terminal's user interface 216.
Alternative or in addition, this information can be input using a
user interface of a given physiological sensor device that provides
such an interface.
[0048] Various commands to access and interact with the user's
virtual physiological model can be generated using the user
interface 216 of the mobile terminal 122. Various types of textual,
graphical, audio, motion video, and animation data received from
the fitness data engine 220 and server 126 can be displayed on the
display 212 of the mobile terminal 122, which also includes a
speaker. In addition, these various data types can be transmitted
from the server 126/fitness data engine 220 to a user by use of a
WEB terminal device 222, television 224, or other access interface
226 that employs a display 228.
[0049] As is shown in the embodiment of FIG. 2A, a physiological
data acquisition system of the present invention preferably
includes at least a heart rate monitor 202. The heart rate monitor
202 is preferably implemented as a personal non-invasive heart rate
measuring device. The heart rate monitor 202, for example, can be
implemented as a two-part device comprising a belt-type heart rate
transmitter containing EKG electrodes and a wristband-type receiver
unit in telemetric inductive or optical connection with the
transmitter. The receiver unit generally includes a microprocessor,
memory, a display, and a user interface.
[0050] In an alternative arrangement, the heart rate monitor 202
can be entirely integrated into a wristband, whereby a sensor, such
as EKG electrodes or a pressure sensor, is also arranged in the
wristband. Alternatively, all of the components can be integrated
into a heart-rate-measuring belt. The rate sensor can further be
implemented as an optical sensor that measures the user's heart
rate. Other configurations of a heart rate monitor 202 as are known
in the art may be employed.
[0051] The user's heart rate can be acquired according to a
monitoring program stored in memory of the heart rate monitor 202.
Heart rate data can, for example, be acquired on a continuous
basis, a variable basis, on command by the user, on the basis of
the user's activity level or in response to a remote command signal
received from by the heart rate monitor 202 from the network 124
via the mobile terminal 122.
[0052] A physiological data acquisition system of the present
invention can employ one or more other types of portable or
ambulatory physiological sensor devices 204. Such portable
physiological sensor devices 204 are typically worn by the user
using a wristband, belt, or other harness that provides for user
comfort and high mobility. In the case of a heart rate monitor 202,
for example, this physiological sensor device is in continuous
contact with the user's anatomy during use. In the case of other
portable physiological sensor devices 204, such devices can be
carried within the user's clothing, pouch or other carrying
arrangement, and be brought into contact with the user's anatomy
only when the physiological parameter of interest is to be
measured.
[0053] A physiological data acquisition system of the present
invention can include various types of non-invasive physiological
sensor devices 208. Such non-invasive physiological sensor devices
208 are typically portable, but need not be in all configurations.
A physiological data acquisition system of the present invention
can also include various types of table-top physiological sensor
devices 206, which are generally not considered highly portable.
Such table-top devices 206 can be situated at a location frequented
by a user, such as the user's home.
[0054] A sphygmomanometer, for example, can be employed as a
table-top physiological sensor device 206 that can be used
frequently to provide accurate measurement of the user's blood
pressure. The table-top physiological sensor device 206, in certain
configurations, can include a user interface 210, such as a user
input device and display, for example. It is noted that the
table-top physiological sensor device 206 or the portable
physiological sensor device 204 can employ an invasive approach to
sensing a particular physiological parameter of the user.
[0055] In accordance with a more complex configuration, a
physiological data acquisition system of the present invention can
include a blood sensing device 211. The blood sensing device 211 is
representative of one or more devices that can be used to measure a
number of blood related parameters. Such blood related parameters
can include oxygen saturation, oxygen consumption, blood chemistry,
and blood pressure, for example.
[0056] FIG. 2B illustrates a number of different physiological
sensor devices that can be employed in a physiological data
acquisition system 250 of the present invention. It is understood
that the devices depicted in FIG. 2B do not represent an exhaustive
listing of devices that can be employed. Moreover, it is understood
that a physiological data acquisition system 250 of the present
invention need not incorporate all of the devices shown in FIG. 2B,
but can incorporate one or multiple devices.
[0057] According to one configuration, the physiological data
acquisition system 250 is intended to represent a portable, and
preferably wearable, unit that provides for local acquisition of
physiological data from one or more physiological sensor devices.
The physiological sensor devices may be integral to or separate
from the physiological data acquisition system 250. Each of the
physiological sensor devices typically communicates with the
physiological data acquisition system 250 via an on-board
communication device, such as a device that conforms to the
Bluetooth wireless specification. The physiological data
acquisition system 250 includes a local interface/transceiver 258
that also operates in conformance with the Bluetooth wireless
specification. Depending on the type of physiological sensor device
employed, a hardwire connection can be established between a given
physiological sensor device and the physiological data acquisition
system 250 via the local interface/transceiver 258. A user
interface 256 and memory 254 are coupled to the processor 252. A
transfer device 257, such as a communication device configured to
operate in conformance with the Bluetooth wireless specification,
is coupled to the processor 252 and provides for uni-directional or
bi-directional communication with a mobile terminal 122.
[0058] In accordance with another configuration, the processor 252,
user interface 256, and memory 254 represent standard components of
a mobile terminal. The transceiver device 256, in this
configuration, represents standard communication circuitry that
provides for communication with a radio network, such as a 2G or 3G
network. In this particular case, block 122 would be representative
of a network, rather than a mobile terminal as is shown in FIG. 2B.
Each of the physiological sensor devices is communicatively coupled
to the processor 252 of the mobile terminal via wireless or
hardwired connections to the local interface/transceiver 258.
Wireless communication between the local interface/transceiver 258
and one or more of the physiological sensor devices is preferably
accomplished in accordance with the Bluetooth wireless
specification.
[0059] As was discussed previously, the physiological data
acquisition system 250 preferably includes a heart rate monitor 260
and may further include a blood pressure monitor 262. A body
temperature sensor 268 can also be used to monitor changes in the
user's body temperature over time, and to develop body temperature
profiles for the user during particular exercise regimens. For
example, monitoring the body temperature of a marathon runner and
developing temperature profiles therefrom can be useful in
developing optimal training regimens for such long distance
runners.
[0060] In a more sophisticated implementation, a physiological data
acquisition system 250 of the present invention can include an
oxygen saturation sensor 264 which non-invasively measures oxygen
saturation of the user's blood. A pulse oximeter, for example, can
be used to measure and compute the arterial oxygen saturation level
of the user's blood from signals received from the pulse
oximeter.
[0061] An oxygen consumption sensor device 266 can be employed to
measure the user's oxygen consumption. According to one
configuration, the oxygen consumption sensor device 266 employs a
breathing apparatus which provides oxygen consumption data to a
processor of the device 266. The breathing apparatus includes a
breathing unit through which the user breathes. In one
configuration, an oxygen consumption sensor directly measures the
user's oxygen consumption and provides output data indicative of
oxygen consumption. A suitable oxygen consumption sensor is
commercially available from Medical Graphics Corporation or Beckman
Instruments.
[0062] In accordance with another configuration, a breathing unit
of the oxygen consumption sensor device 266 is coupled to a flow
sensor which measures air flow passing through the sensor. Air flow
data is transmitted from the flow sensor to the processor of the
device 266. In accordance with this configuration, an ambient
oxygen sensor is used to determine the content of oxygen in the
ambient air, and a second oxygen sensor senses the content of
oxygen in the patient's expired air. Alternatively, the content of
oxygen in ambient air may be assumed to be 20.93%. The processor of
the oxygen consumption sensor device 266 uses the air flow data
acquired from the flow sensor, oxygen content data received from
second oxygen sensor 67, and assumed (i.e., 20.93%) or sensed
oxygen content data (i.e., via the ambient oxygen sensor) to
compute oxygen consumption of the user in real-time.
[0063] According to a more sophisticated implementation, a
physiological data acquisition system of the present invention can
include a blood chemistry sensor device 265 which enables various
non-invasive blood chemistry measurements. Such blood chemistry
measurements can include measurement of hemacrit, which is a
measure of the fractional level of red blood cells in the blood,
hemoglobin, tissue perfusion, and oxygenation. According to one
approach, non-invasive blood chemistry measurements are obtained
using NIR (near infrared) spectroscopy techniques.
[0064] By way of example, a sensor of the blood chemistry sensor
device 265 can employ photonic methods based on fluorescence. For
example, the blood chemistry sensor device 265 contains a colored
dye immobilized in a polymer film. A blue LED excites fluorescence
while a photodiode monitors the resulting red emission. Oxygen
interferes with the fluorescence. Greater concentrations of oxygen
diminish the red fluorescence emission. A suitable non-invasive
blood chemistry measurement device is commercially available from
PhotoSense LLC.
[0065] In yet another implementation, a physiological data
acquisition system 250 of the present invention can include a
percent body fat sensor 270. The percent body fat sensor 270
typically includes a number of electrodes that contact surfaces of
a user's two hands. Monitoring circuitry transmits monitoring
signals between a first pair of the electrodes when in contact with
the user's hands. In response to transmission of the monitoring
signals, the resistance between a second pair of the electrodes in
contact with the user's hands is detected. Percent body fat of the
user is computed using the detected resistance.
[0066] An activity sensor 272 can also be incorporated into a
physiological data acquisition system 250 of the present invention.
The activity sensor 272 can include an accelerometer, such as a
MEMS (Micro-ElectroMechanical Systems) accelerometer. The activity
sensor 272 senses changes in the activity level of the user, and
can be used for a number of purposes, such as optimizing
physiological sensor device sampling durations and rates, for
example.
[0067] Turning now to FIG. 3, there is depicted a display 300 on
which various types of fitness data within the context of the
present invention are displayed.
[0068] The display 300 represents a display of a mobile terminal, a
television, and WEB terminal device, or the display of another
access device. Various textual data can be presented, including the
data types 304 acquired by the physiological data acquisition
system and user input data, such as weight and age, for example.
Current fitness data 306 generated by the fitness data engine can
be presented on the display 300. Historical fitness data 308 can
also be presented on the display 300. Predicted fitness data 310
generated by the fitness data engine can be presented.
[0069] A visual representation of the user and user's state of
physical fitness can be graphically presented on the display 300.
Various physical attributes of the user can be visually depicted in
the form of an avatar 302. The present form of the avatar 302b can
be displayed, as can a past form 302a based on historical fitness
data. Changes to the avatar in response to changes in the user's
acquired physiological data over time can be visually depicted.
Predictions based on historical physiological data or test
physiological data and/or training regimen parameters can be
performed to produce data used to develop a future form of the
user's avatar 302c. A single avatar or multiple avatars can be
selectively presented on the display 300 by the user.
[0070] Methods of the present invention can be implemented using
the systems and devices described above. In accordance with one
particular embodiment, a small number of physiological measurements
is acquired from use of a physiological sensor device that requires
minimal user intervention, such as a heart rate monitor. By way of
example, a pedometer can be employed for calculating energy
consumption and heart rate monitoring at a frequency of once a day
for thirty seconds while resting. It is understood that the
frequency of sampling can be different, but that in this embodiment
only a minimal amount of physiological data is needed. Each of the
physiological sensing devices directly communicates with the mobile
terminal (e.g., via Bluetooth), which relays the information to the
network server. The fitness engine on the server calculates the
impact of the data on the avatar, and the user can access the
updated version of the avatar via one of several access interfaces
(e.g., mobile phone, WEB terminal device, TV, etc.). From the
perspective of the user's overall experience, it may be desirable
to modify the avatar only on a weekly or bi-weekly basis, rather
than upon receipt of each set of newly acquired physiological
data.
[0071] FIG. 4 illustrates a method of acquiring physiological data
from a user and communicating the physiological data via a mobile
terminal to a network server for integration into a virtual
physiological model established for the user in accordance with an
embodiment of the present invention. According to this approach,
which is consistent with a general implementation of the present
invention, physiological data of various types is acquired 402 from
the user. The physiological data is transmitted 404 to a mobile
communication device, such as mobile terminal. The physiological
data is communicated 406 from the mobile terminal to a network
server. The physiological data is integrated 408 into a virtual
physiological model of the user, such as an avatar.
[0072] FIG. 5 illustrates a method of acquiring heart rate data and
other data acquired from a user, and communicating this data via a
mobile terminal to a network server for integration into a virtual
physiological model established for the user in accordance with an
embodiment of the present invention. According to this method,
general information about the user, such as weight, gender, age,
and height, for example, is acquired 502 from the user. Heart rate
data is acquired 504 from the user, preferably throughout the day.
Other types of physiological data can also be acquired 506. The
general and physiological data is transmitted 508 to a mobile
terminal via a wireless link and from the mobile terminal to a
network server 510. These data are integrated 512 into a virtual
physiological model of the user.
[0073] FIG. 6 illustrates a method of generating fitness data and a
visual depiction of the user based on physiological data acquired
from a user, and communication of the generated fitness data to the
user for presentation on a local display device. According to this
method, physiological data is acquired 602 from the user and
transmitted to a network server via a mobile terminal. The
physiological data is integrated 604 into the virtual physiological
model representative of the user. Fitness data is generated 606
using data associated with the virtual physiological model. A
depiction of the user is generated 608 using virtual physiological
model data. Changed data or a changing depiction of the user (i.e.,
avatar) are generated 610 in response to changed virtual
physiological model data, prediction analysis or input of test
physiological data set(s).
[0074] The physiological data and user depictions are communicated
612 to the user via the mobile terminal or other access/display
device. Physiological data and user avatar(s) can be displayed 614
on a mobile terminal display, television, WEB terminal, or other
use access/display device.
[0075] The foregoing description of the various embodiments of the
invention has been presented for the purposes of illustration and
description. It is not intended to be exhaustive or to limit the
invention to the precise form disclosed. Many modifications and
variations are possible in light of the above teaching. It is
intended that the scope of the invention be limited not by this
detailed description, but rather by the claims appended hereto.
