Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application is a Continuation of U.S. patent
application Ser. No. 11/377,072, filed Mar. 15, 2006, which claims
the benefit of Provisional Application Nos. 60/661,652, filed Mar.
15, 2005 and 60/681,877, filed May 16, 2005, the disclosure
contents of which are hereby incorporated herein by reference in
their entity.
FIELD OF THE INVENTION
[0002] This invention relates generally to human work environments
and particularly to ergonomic workstations.
BACKGROUND OF THE INVENTION
[0003] One of the consequences of the technology in the workplace
has been the emergence of highly specialized machines and machine
control environments. These machines and machine controls such as
computer controlled systems have greatly increased the productivity
and efficiency of workers by grouping substantial operative and
control functions within a single compact environment minimizing
the amount of movement and travel required by the worker to control
diverse and complex functions. As workplace architects and creators
have endeavored to further increase the effectiveness and
efficiency of workers, greater numbers of controls and functions
have been more densely grouped into smaller and smaller workspace
type areas often referred to as workstations. Such work stations
have achieved considerable variation and have included
manufacturing system control facilities, computer work stations for
information process, secretarial and administrative office
environments as well as other facilitates throughout much of the
modern industrial scene including inspection and fabrication
stations, on assembly line type facilities, or the like.
[0004] While such highly efficient and compact workstation
environments have greatly increased worker productivity and
efficiency, the burdens imposed upon the worker in a workstation
environment, which essentially limits the ranges of motions, muscle
group changes, postural changes, and rest needed, by the worker.
This environment has given rise to substantial risks of injury and
other problems to the users of these workstations.
[0005] In particular, the tendency for such work stations to
utilize a restricted seating portion for the worker and the
manipulation of densely compacted controls such as a computer
keyboard or the like has given rise to a variety of maladies such
as the well known carpal tunnel syndrome as well as a variety of
musculo-skeletal ailments generally referred to as repetitive
motion syndrome.
[0006] One of the most common examples of such problems is the
painful injury which often afflicts those operating computer
keyboards for extended periods of time as the repeated high speed
limited motion of the computer operator's fingers in a fixed
keyboard position which gives rise to the carpal tunnel syndrome
type injury.
[0007] Practitioners in the art have endeavored to provide
workstation environments that are more ergonomic and provide
improved support and adjustability of the operating environment to
suit the physical dimensions and characteristics of the operator.
Practitioners have provided work station environments in which the
user is able to adjust the various operating dimensions of the work
space environment such as the table height, the keyboard height,
the height of footrest and chair seating surfaces as well as the
angle of chair back supports and the distance to the worktable and
so on.
[0008] For example, U.S. Pat. No. 5,098,160 discloses an ergonomic
seating system apparatus that includes a linear alignment member
with an interconnected seating device such as a chair. An
adjustable footrest is provided in combination with the linear
adjustment and alignment member. The chair and linear alignment
member and footrest are positioned with respect to a workplace
environment such as a desk and computer. The user is able to adjust
the chair position and height as well as the footrest height
independently to optimize the ergonomic position for the user. This
type of device still limits needed variation in position and other
adaptations for the user that could alleviate or avoid injury.
[0009] U.S. Pat. No. 4,779,922 discloses a work station system in
which a planar base supports a multiply articulated chair having an
angularly movable backrest and various adjustable independently
movable support pads and surfaces. An angularly movable support is
coupled to the chair and includes a computer monitor and keyboard
all capable of independent adjustment. This type of device still
limits needed variation in position and other adaptations for the
user that could alleviate or avoid injury. This device also lacks
user guidance to optimal positioning and limits adaptation to user
only initiated positioning.
[0010] U.S. Pat. No. 5,106,141 issued to Mostashari sets forth a
motorized mobile office for use in a van-type vehicle or the like.
The interior of the van is configured to receive and support a
complete workstation including a support chair and a computer
keyboard support with additional surrounding work surfaces. This
type of device still limits needed variation in position and other
adaptations for the user that could alleviate or avoid injury. This
device also lacks user guidance to optimal positioning and limits
adaptation to user only initiated positioning.
[0011] U.S. Pat. No. 5,122,786 sets forth an ergonomic keypads for
desktop and armrest applications in which a pair of left and right
ergonomic keypads are separately positioned on a desktop or armrest
of a chair to permit the user to operate the keypads while assuming
a more comfortable and natural hand and wrist position. The
separate keypads may be hingedly interlockingly to function as a
compact unitary keyboard for desktop use.
[0012] U.S. Pat. No. 4,585,363 discloses a therapeutic aid for use
by a patient in developing fine, medium and gross arm movements.
The device includes a pair of elongated adjustable length arms
pivotally coupled at their junction and securable at one end to a
chair backrest or the like. A pen or other therapeutic apparatus
may be secured to the remaining end of the pivotal arm combination
and serves as a guide for arm and hand movement on the part of the
user. This type of device still limits needed variation in position
and other adaptations for the user that could alleviate or avoid
injury. This device also lacks user guidance to optimal positioning
and limits adaptation to user only initiated positioning.
[0013] U.S. Pat. No. 20020041785 sets forth a workstation that
includes a worktable and chair defining workstation geometry. A
plurality of adjustable elements is utilized within the workstation
to facilitate variation of the workstation geometry. A controller
is coupled to the adjustable elements of the workstation to apply a
gradual long-term motion profile signals to the adjustable elements
of the workstation. The work station geometry is varied in response
to the imposition of the motion profile signals upon the adjustable
elements of the work station to provide substantially imperceptible
changes of the work station operator's physical position to avoid
or minimize the many maladies associated with restricted or limited
motion operation within work stations. Further, a continuous
passive motion keyboard is provided that changes the keyboard
position relative to the keyboard user. While this keyboard may
move it is not interactive, it lacks the ability to make regular
specific movements based on workload or time spent working. This
keyboard does not monitor the user to produce a safer environment,
it just moves at intervals unrelated to the input or stress of the
user from the task. This causes unnecessary interruptions at random
intervals to the worker without any guarantees of benefit. It also
limits adaptation to movement only and no customization of such
movement is available.
[0014] FIG. 1 shows a manually positionable ergonomic keyboard by
use of a plastic crankshaft. It is clumsy and difficult to use. The
user is given no indication on when if or how much to move the
board. The keyboard is unable to guide the user to position it
optimally. Additionally no attention at all is given to static
loading, a requirement to carpal tunnel/repetitive strain injury.
Additionally, the lack of a corresponding wrist rest allows wrist
hyperextension. This type of device still limits needed variation
in position and other adaptations for the user that could alleviate
or avoid injury. This device also lacks user guidance to optimal
positioning and limits adaptation to user only initiated
positioning.
[0015] FIG. 2 is another ergonomic keyboard. This keyboard is split
and manually moveable in a tenting and splaying motion. This
keyboard is not motorized or sensored. It offers no way to guide
the user to the best keyboard positions. A manual adjustment
mechanism is used so for the user can decide on the best course of
treatment. There is no adaptation at all to address repetition a
key component to carpal tunnel syndrome and repetitive stress
injuries. This type of device still limits needed variation in
position and other adaptations for the user that could alleviate or
avoid injury. This device also lacks user guidance to optimal
positioning and limits adaptation to user only initiated
positioning.
[0016] FIG. 3 shows a stationary ergonomic keyboard. There is no
human adaptation at all. The keyboard does not alter its position
at all. There is no attention or adaptation for different sized
users, different injuries or environments. This keyboard fails to
address most of the needs of carpal tunnel and repetitive stress
injury sufferers. In fact, it does nothing to address the chief
cause of carpal tunnel and repetition strain injury, repetition
itself.
[0017] While the foregoing described prior art devices have
provided improvement over fixed inflexible work station
environments or ordinary flat keyboards, there remains a continuing
need in the art for work station environments and apparatuses that
provide further attention to the physical needs of the user and
which protect the user more substantially against the limited
motion and confined motion types of injuries such as carpal tunnel
syndrome or repetitive motion syndrome. Such improvements would
include programs that detect the user's needs and act
accordingly.
SUMMARY OF THE INVENTION
[0018] An ergonomic keyboard that alleviates repetitive stress
injuries by eliminating static repetition in the use of keyboards.
The keyboard includes a plurality of key zones, the key zones being
adapted to move. The zones are moved by moving means. The key zones
move when any one or more of predetermined conditions occur such as
a set time, number of keystrokes, time interval, keystrokes in a
zone or area, preprogrammed injury status, preprogrammed injury
prevention, programmed diagnosed condition, key temperature,
keyboard vibration, manual adjustment, and user pattern or
preference. A keyboard and or mouse or similar input devices used
mainly with computers as a therapeutic and palliative instrument
for injuries like carpal tunnel syndrome and repetition strain
injury is disclosed. The keyboard, mouse, trackball, or other
device is preferably programmed through the computer or onboard
programming to move in sequences. This keyboard would be able to
monitor the user's workload related to keyboard, mouse, or other
input peripherals. In a preferred embodiment, this keyboard senses
where and how changes could be made to protect the user from
injury. This keyboard then executes these changes automatically.
These programmed sequences would change in order to alleviate
specific conditions like carpal tunnel. Changing positions and
other adaptations in timed intervals, or other parameters as
discussed above would assist the user by altering the position of
nerves, change the blood flow, and interrupt static loading to
certain muscle groups, ligaments, tendons, and nerves during the
task of using these devices. This movement would diminish the
affect on any one area of the body and allow the injured or
affected area to be less involved in the task of using the devices,
or improve the function and environment of the at risk area
resulting in a state of rest and recuperation the motion sequence
increases the chance of alleviating the condition. The device
would, through the use of a master control program in the keyboard,
computer, server or wireless control device, be able to alleviate
specific conditions or go through a general movement program
whereby the keyboard and or mouse changes positions when work load
parameters are met to help prevent conditions exacerbated by or
caused by the use of these and other input devices. Motors or other
devices would move the keyboard and mouse or other input devices.
In addition the keyboard, mouse and other devices may have sensors
to help track and change adaptations as necessary or to accumulate
data.
[0019] Adaptations include, but are not limited to, position,
movement, of the keys, keyboards, wrist support or multiple zones
within a keyboard. Temperature changes to the keys, wrist rest
including cooling and warming to circulation and provide comfort.
Key height and tension can preferably be altered targeting specific
zones that are overused for instance providing less strain to
overused finger and wrist muscles. In one embodiment, the keyboard
includes a wrist support where the wrist tractions. The wrist
support preferably includes a temperature control to cool or warm
the wrist support to optimal levels for the user.
[0020] A therapeutic/or ergonomic keyboard and mouse or similar
input devices used mainly with computers is disclosed. The Keyboard
and mouse or trackball or other devices is programmed through the
computer or via controls located on the device itself to move the
device in sequences or random movements. These sequences or
movements are programmed to vary positions. This would alleviate
specific conditions like carpal tunnel, or repetitive strain
injury. By changing positions in timed, random, or other parameters
including but not limited to keystroke count, temperature, measured
accumulation of pressure or set intervals positions, or when work
load parameters are met to help prevent conditions exacerbated by
or caused by the use of these and other input devices. It would
assist the user by incorporating more muscle groups. These changes
would allow the injured or affected area to be less involved in the
task of using the devices, go into a state of rest and recuperation
and increases the chance of alleviating or preventing the
condition. The deliberate pattern of changes and keyboard motion
could diminish the adverse affects on the user in a specific way.
For instance movement could be programmed to alleviate overuse to a
specific anatomical area like a specific muscle group. The keyboard
would maneuver in a way to alleviate an injury to one of the hands
by moving a specific are or zone on the keyboard related to the
injured hand or wrist. Movements would be programmed to accomplish
certain palliative tasks, for instance the keyboard can arrange
itself in a way to decompress the median nerve that is usually
compressed with a typical keyboard. Stretching out the wrist with
the wrist support and altering key angle to optimal position could
do this. Additionally the keyboard and or wrist guard could
alternatively cooled and warmed to further affect blood flow and
decrease pain to the area. This allows the injured or affected area
to be optimally adapted to the user and increases the chance of
alleviating the condition.
[0021] The device, through the use of a master control program in
the computer or through an on board control device, alleviates
specific conditions or oscillates through any number of movements
during a time period to help prevent conditions exacerbated by or
caused by the use of these and other input devices. At least one
motors or other device moves the keyboard, mouse, or other input
devices. In addition, the keyboard, mouse, and other devices
preferably have sensors to help track and change position as
necessary or just to accumulate data.
[0022] In one embodiment, this device is controlled through an on
board controller. The controller is located on the device or,
alternatively, in the keyboard itself, on the computer, solid state
memory chip, or on the server or embedded on the logon program or
through the World Wide Web. Communication takes place between the
controller and the keyboard via a WIFI connection, Bluetooth,
RS232, USB, firewire, serial communication, parallel communication,
or the like. The controller preferably has options such as velocity
changes, height change limitations and the like, activated by
switches, sensors, on the like. In one embodiment, the device is
controlled remotely or by other means either located on board, in
the computer, or on a server.
[0023] The keyboard or mechanism is preferably split into a
plurality of zones, where a zone includes the keys surrounding the
key being used, the zone itself would then move and change when use
parameters are met. The keyboard or mechanism would have any number
of zones. In one embodiment, the zones are variably sized. The
zones will move according to the use of that zone. In this way, the
keyboard is suited to make changes necessary to engage the small
bones of the wrist and fingers and the small muscles, tendons and
ligaments utilizing programming on the keyboard as well as on the
pc, network, server, internet, and the like.
[0024] In one embodiment, the keyboard changes the environment to
suit the user's needs. It also monitors the user's needs to tailor
the output as necessary. In one embodiment, the keyboard moves
using motors with or without gears, pneumatics, hydraulics,
magnetic pull, and assorted other mechanisms and technologies.
[0025] Those skilled in the art can use materials to make this
keyboard including but not limited to Plastics, rubber, metal
alloys, or even a projected image on a moving surface. The sensing
apparatus monitors compliance and use patterns with keystroke
weight, vibration, infrared motion detection, heat sensors, or a
mat under the keyboard sensing accumulated weight or vibration, and
the like. A variety of power sources power the keyboard including
USB power from the computer or other connection capable of carrying
or transmitting power, power and data together and rechargeable and
not rechargeable batteries, solar power, AC or DC powered, power
cell technology, and the like.
[0026] Several types of movement are possible including splaying of
the hands, hand/wrist/forearm rotation, flexion, extension,
pronation, supination, and other desired movement to avoid injury.
The keyboard is programmed to move, change or adapt using a
keyboard based mechanism such as a circuit board built into the
keyboard, a program on the pc, a program on the server, a program
on the Internet a program on a wireless device, solid state memory
chip or the like.
[0027] Various means are used to identify users and link those
users to their preferably individualized keyboard movement program
including biometrics, smartcards, passwords, and other unique
identifiers.
[0028] Any one of several parameters prompt movement, including
number of keystrokes, accumulated motion, time, weight, vibration,
or the like.
[0029] It is the particular object of the present invention to
provide an improved workstation that tends to minimize or prevent
injury to the user resulting from limited and repetitive motion,
static loading, accumulated stress to the body parts used in
keyboarding.
[0030] It is the object of this invention to present an
artificially intelligent, interactive design that is passively
compliant. No action is needed by the user to make biomechanical
adjustments to the keyboard to avoid injury. The programs are
preferably automated and require no action to comply with the
improved system. The keyboard is capable of learning the user's
needs and making appropriate changes in order to help prevent
injury to susceptible body parts engaged in typing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0042] FIGS. 4 and 5 depict a split keyboard 2, 3 resting in a
shell 1. Both halves of the keyboard 2, 3 have a plurality of legs
4 that extend and retract to produce movement. The legs are motor
and or shaft driven and can move about 3 inches. Movements include
supination, pronation, flexion, extension, rotation, as well as
other movements. In one embodiment, each leg is individually
controlled and able to make almost unlimited variations of changes
and angles with the keyboard, depending on the needs of the user.
In one embodiment, the base has moving components that move the
keyboard zones.
[0043] A program that controls the keyboard could preferably be
alerted to a specific condition of the user such as a left sided
median nerve entrapment. The keyboard would then make an automatic
deliberate set of changes to optimize the keyboard for that
condition. The keyboard preferably identifies each user with
biometrics, password, smart card technology, or other unique
identifiers. In this way each user has their own profile, and the
keyboard knows the last position, keystroke and history of the user
and preferably engages that user's profile automatically.
[0044] In one embodiment, sensors or timers measure actual movement
of the keyboard or keystrokes and controls how much the legs move.
Preferably, there is an on/off switch 5 and a user skill level
switch 6 as well as a switch 7 to control which side of the
keyboard or if both sides remain active. The movement can be
deliberate or change automatically over time based on usage or
other programming, and can be gradual as to not interfere with
usability. Asymmetrical movements are also available in one
embodiment. On board control, pc control, or server control is
utilized. In one embodiment, a graphical interface would be
available on screen or on the keyboard. Alternatively a digital
display would be available on the keyboard itself. This way the
user could confirm the profile is his and how soon or how much the
key board will be changing as well as see how much work has been
done so far by keystroke or time or other indicators.
[0045] FIGS. 6 and 7 depict a split keyboard where there are no
outer shell only two halves 8 and 9. Each half articulates and
moves. Legs 10 are motor and/or shaft driven and can move about 3
inches or more. Movements produce hand or wrist supination,
pronation, flexion, extension, and rotation as well as other
movements. Sensors or timers measure the actual movement and
controls how much the legs move. There is an on/off switch 11 and a
user skill level switch 12. The movement can be deliberate or
change automatically over time based on usage or other programming,
and can be gradual as to not interfere with usability. Asymmetrical
movements are also available in this embodiment. On board control,
pc control, server control can be utilized by those skilled in the
art to sense and adapt to the users needs. Magentics, hydraulics,
pneumatics and other techniques can also be used to attain
movement.
[0046] FIGS. 8 and 9 set forth an embodiment of the keyboard
mechanism with two split components 13 and 14. The components sit
in a shell 16 that, in one embodiment, ascends toward the middle.
The motor preferably sits in the middle of the keyboard 15 under
the highest area or in the topmost section of the keyboard. The two
halves are pulled and pushed along this surface with guides and
gears, pulleys, magnets, and the like to accomplish splaying, (FIG.
8), rotation (FIG. 9) and elevation. Movements produce supination,
pronation, flexion, extension, and rotation in the hands and wrists
as well as other movements. Sensors or timers measure the actual
movement and controls how much the legs (attached to gears) and in
turn, the sections of the keyboard, move. The movement can be
deliberate or change automatically over time based on usage or
other programming, and can be gradual as to not interfere with
usability. Asymmetrical movements are also available in this
embodiment. On board control, pc control, server control can be
utilized by those skilled in the art. The wrist rest 17 also is
movable and can produce pressure changes as well as vibratory
massage and temperature changes to help alleviate conditions to the
area of concern.
[0047] Another embodiment of the keyboard mechanism has multiple
split components. In other words, there are a plurality of keyboard
sections, each section being independently moveable. The components
sit in a shell that has multiple peaks between the components. The
motor preferably sits in the middle of the keyboard under the most
ascended area or in the topmost section of the keyboard. The
multiple split components are pulled and pushed along this surface
with guides, pulleys, and gears to accomplish splaying, rotation
and elevation. Movements include supination, pronation, flexion,
extension, and rotation as well as other movements. Sensors or
timers measure the actual movement and controls how much the legs
and in turn, the sections of the keyboard, move. The movement can
be deliberate or change automatically over time based on usage or
other programming, and can be gradual as to not interfere with
usability. Asymmetrical movements are also available in this
embodiment. The movement can be deliberate and change automatically
over time based on usage or other programming, and can be gradual
as to not interfere with usability. On board control, pc control,
server control can be utilized by those skilled in the art.
[0048] In another embodiment, semi solid materials are used for the
keys that undulate and move through the uses of electrostatic
current. The multiple split components are pulled and pushed along
this surface with guides, gears, pulleys, magnets, and the like to
accomplish splaying, and rotation. Movements include supination,
pronation, flexion, extension, and rotation as well as other
movements. Sensors or timers measure the actual movement and
controls how much the legs move. Asymmetrical movements are also
available in this embodiment. On board control, pc control, server
control can be utilized by those skilled in the art.
[0049] Another embodiment of the keyboard mechanism split into
multiple sections consisting of two or more sections. The sections
are all substantially on an underlying surface of the keyboard,
which elevates towards the middle and towards the outer edges, and
descends towards the front. Legs attach the keyboard sections to
underlying gears. Multiple gears, and multiple motors, if
necessary, allow the sections of the keyboard to move either as a
group or individually to each area of the underlying surface. This
allows for splaying, rotation, elevation, and declination of each
section of the keyboard either individually or separately. The
movements can be customized for each user separately, and the
design allows for a large number of configurations. The movement
can be deliberate or change automatically over time based on usage
or other programming, and can be gradual as to not interfere with
usability. On board control, pc control, server control can be
utilized by those skilled in the art.
[0050] Another embodiment of the keyboard mechanism split into
multiple sections consisting of two or more, where each section is
sitting on a motorized pivot in the center. This allows for all
degrees of motion in every possible angle on every plane. The
movements can be customized for each user separately, and the
design allows for a large number of configurations. The movement
can be deliberate or change automatically over time based on usage
or other programming, and can be gradual as to not interfere with
usability. On board control, pc control, server control can be
utilized by those skilled in the art.
[0051] Another embodiment of the keyboard mechanism, where in
addition to the movements described above, the wrist rest in front
of the keyboard will have the ability to elevate and descend,
change temperature and vibrate and to adjust wrist position in
relation to the keys. This can be done based on programming or
manual control, and will be accomplished by a motor or gearing or
other mechanisms under the wrist rest which, attached to gears,
will allow legs underneath to raise and lower the wrist rest.
[0052] It will be apparent to those skilled in the art that the
imbedded software will be able to make changes randomly or based on
programming for a specific ergonomic issue or a specific user. The
changes will be gradual or immediate depending on the settings and
can be customized for different users.
[0053] The software will preferably include, but not be limited to
programming aimed at relieving or preventing a specific disease
such as carpal tunnel or other ailments due to repetitive motion.
The gradual movements of the keyboard sections eliminate repetitive
motion from the same angle improving blood flow, changing position
of the median nerve, and resting overworked muscles.
[0054] The software programming will preferably monitor repetitive
motion on specific keys and adjust the keyboard sections
accordingly. If a user is constantly focusing on one small section
of the keyboard, then the programming will adjust that section
accordingly, moving it more frequently, or various other
angles.
[0055] The software can be stored on the keyboard itself, the
computer to which it is attached, a third party computer or a
server on the network, a dedicated hardware controller, or on an
external source such as a key card or a USB memory card, solid
state memory or other storage mechanisms.
[0056] In one embodiment, the customization of the software can be
manipulated by use of pre-programming, settings stored on the
computer or server or by user input. The configuration changes can
be made automatically when the user logs the computer into the
operating system. It can also be automatically configured with the
help of biometrics or their personal key cards or identification
cards. Once the user is identified, the software, wherever it is
stored, can adjust the keyboard for that specific user.
[0057] Biometrics or key card access, which could be imbedded in
the keyboard, could assist or even replace the logon process. Logon
and keyboard manipulation can be accomplished is one step if
desired. For this configuration, drivers for the keyboard will be
loaded upon startup, as opposed to upon login to the operating
system.
[0058] Another embodiment could offer key and wrist rest
temperature changes in addition to the other mentioned adaptations
to alleviate common hand and wrist and arm ailments.
[0059] Another embodiment could offer key tension and height to
change pressure to the muscle groups of the hand and wrist and
offer changes to alleviate painful conditions of the hand.
[0060] Another embodiment offers central, or local monitoring of
program compliance. The programs mentioned could be disabled by the
user, If they are disabled the program would notify the centralized
compliance monitor. The user as well as reminders would then
automatically generate messages to encourage compliance. This
program would maintain records of each keystroke made with the
system engaged and not engaged. These records would be stored in a
secure file or server and can be referenced in a report form for
use as a legal document. Global use programs would also be
available to see how as compliant the group or company is.
[0061] Another embodiment would have the sections of the keyboard
light up in a fashion to alert the user that movements and
adaptations were occurring.
[0062] FIG. 9 sets forth an embodiment having a motor and gearing
in a cylinder hinge. The hinge is located between two halves 19 and
20 of the keyboard. The motor is controlled by previously mentioned
mechanisms. An on board on/off switch is also built in. As the
motor engages, it would cause the hinge to rotate elevating the
center of the keyboard.
[0063] In one embodiment, the keyboard has a sleep or shut down
mode where the keyboard recognizes inactivity and ceases operation,
waiting for the keyboard to be reactivated. In this way position
changes will only occur when the user is typing. This insures that
the user will benefit from each action the board takes and
therefore the user will benefit from a precise non-random
regiment.
[0064] FIG. 10 shows another embodiment having a center pivot
housing portions 19, 20 and an on/off switch 21.
[0065] Another embodiment offers on screen or on board digital and
or graphical display of the user/keyboard status. Anticipated or
movements occurring will be visible in addition to key stroke
count, finger temperature and other info pertinent to keyboard
interaction.
[0066] Another embodiment would use all previously mentioned
programming with a projected or imprinted keyboard to a cushioned
or rubberized or other type of surface that would move in ways not
encumbered by physical keys. It could be a water or air filled
device or other material that would shift and change temperature,
position as required and previously mentioned. Alternatively, the
keyboard is moved using piezoelectric elements, or the like.
[0067] FIG. 11 sets forth a preferred embodiment of the software
system. Identification of each individual user would be
accomplished using smart card technology 22, biometric
identification 23, or other identifiers attached to the keyboard 24
or computer 25, like a password. The keyboard could have on board
technology and programming. Alternatively, programming would be
available through the PC 25 and have the data stored there or on a
server 26. Wireless device communicating with the keyboard could
also house the programming.
[0068] In one embodiment, the keyboard 24 is coupled to the
computer 25. The computer 25 is coupled to a server 26 via a
connection. In one embodiment, the computer 25 is connected to the
server 26 via the Internet 27. A user preferably logs onto computer
25 or keyboard 24 so that a customized articulation of the keyboard
is implemented. In a preferred embodiment, a program that controls
the keyboard is resident in the keyboard, i.e., the keyboard
includes an ASIC, microcontroller, circuitry, or the like to
control the keyboard. Alternatively, the program is stored on the
computer 25 or network 26. It should be noted that the connections
can be wireless or wired.
[0069] In operation, the program monitors the keyboard activity of
the user and articulates the keyboard in response to the user's
activity. It should be noted that while keystrokes represent
activity, time of use is preferably monitored. In other
embodiments, key pressure or activation force are also monitored.
In one embodiment, the program includes predefined movements for
specific user problems i.e., users having carpal tunnel syndrome,
or predefined motions to avoid getting such problems.
[0070] In one embodiment, the program tracks keyboard usage. This
data is preferably collated at a central location. By collating
data, companies can determine how much a specific user is typing
and use this to determine if a repetitive stress injury is possible
or the result of improper keyboarding. Additionally, companies can
collect data to insure that repetitive stress injury tactics are
being employed be typists.
[0071] The disclosed keyboard is preferably adapted to articulate
in response to user activity. The keyboard has a plurality of
zones. In one embodiment, the zones are preset, i.e., two zones,
each being one half of the keyboard divided about a center line, or
a plurality of keys grouped by location such as Q, A, Z, W, S, X,
E, D, C. In another embodiment, the zones are keys grouped by
usage.
[0072] The disclosed keyboard is moved using motors, pulleys,
magnets, piezoelectric elements, gears, hydraulics, pneumatics, and
the like. In one embodiment, the zones are moved using
telescopically extending legs. In one embodiment, the keyboard
includes a base and a plurality of key zones. Each key zone is
independently moveable. In another embodiment, the movement of each
key zone is interrelated. In one embodiment one motion device moves
each keyboard zone whereas in another embodiment, each zone is
controlled via its own motion device. Alternatively, clutches are
used to control which zone is moved. Motion is accomplished by
moving cams under each zone, telescopically extending legs, having
the zones move on ramps, spring compression and expansion, raising
and lowering the zone using screw leads, and the like, and any
combination of these means for moving the keyboard.
