[0001] This application claims priority under 35 U.S.C. .sctn.119
from Korean Patent Application No. 10-2012-0129810, filed on Nov.
15, 2012, in the Korean Intellectual Property Office, the

providing a wearable device, an exercise service providing system,
and a method of providing an exercise service by using the same,
and more particularly, to providing a wearable device that a user
wears on a body, a display device to provide an exercise service
based on a value sensed by the wearable device, an exercise service
providing system, and status managing methods thereof.
[0004] 2. Description of the Related Art
[0005] Various types of electronic devices have been developed and
supplied with the development of electronic technologies. In
particular, various types of display devices, such as a TV, a
portable phone, a tablet PC, a laptop PC, a PC, etc., have been
widely used. Therefore, the needs of users to be provided with
various types of services by using display devices have been
increased.
[0006] For example, a user plays contents, such as instructional
videos teaching yoga, dances, and other exercises on a display
device, and after viewing the contents, attempts to copy the poses
shown in the contents. However, it is difficult for the user to
know whether they have exactly copied the pose that they want to
take. In particular, when the user does yoga, the user is to take
an exact pose in order to maximize an exercise effect. Therefore,
when the user takes a wrong pose, the exercise effect may be
reduced compared to an exercise time.
[0007] Accordingly, a technology for exactly measuring and managing
a pose of a user is required.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0039] Reference will now be made in detail to the embodiments of
the present general inventive concept, examples of which are
illustrated in the accompanying drawings, wherein like reference
numerals refer to the like elements throughout. The embodiments are
described below in order to explain the present general inventive
concept while referring to the figures.
[0040] The matters defined in the following description, such as
detailed construction and elements, are provided to assist in a
comprehensive understanding of the exemplary embodiments of the
present general inventive concept. Thus, it is apparent that the
exemplary embodiments can be carried out without those specifically
defined matters. Also, well-known functions or constructions are
not described in detail since they would obscure the exemplary
embodiments with unnecessary detail.
[0041] FIG. 1 is a block diagram illustrating a structure of a
wearable device 100 according to an exemplary embodiment of the
present general inventive concept. The wearable device 100 refers
to a device that is formed of a flexible material to be worn by a
user. For example, the wearable device 100 may be various types of
wearable devices that humans or animals may wear on their bodies,
such as clothes, shoes, glasses, hats, accessories, etc.
Hereinafter, a wearable device 100 which is realized in a clothes
shape will be described but is not limited to this type. Therefore,
the wearable device 100 may be realized as various types.
[0042] Referring to FIG. 1, the wearable device 100 includes a
motion sensor 110, a bio-signal sensor 120, a controller 130, and a
communicator 140.
[0043] The motion sensor 110 senses a motion of a user. The motion
sensor 110 may include for example an electromyogram (EMG) sensor,
an acceleration sensor, etc. to sense the motion of the user.
[0044] An EMG sensor senses a bioelectrical signal accompanied by
muscle activities of the user through electrodes attached to a body
of the user. In detail, a potential difference formed between the
electrodes attached to the body of the user is amplified through a
differential amplifier circuit, a noise is removed from the
bi-electrical signal through a notch filter or the like, and the
bioelectrical signal from which noise has been removed is provided
to the controller 130. The controller 130 compares a current EMG
signal with a previous EMG signal to determine whether muscles of
the user are relaxed or contracted in order to estimate the motion
of the user.
[0045] An acceleration sensor senses an inclination degree by using
gravity. In other words, if a gravity value, which is obtained when
sensing is performed in a vertical direction, is 1 g, and the pose
of the user is inclined, a value lower than 1 g is obtained. If the
pose of the user is upside down, -1 g is obtained. The acceleration
sensor outputs a pitch angle and a roll angle by using this
principle. If the wearable device 100 is realized in the clothes
shape, acceleration sensors may be respectively distributed in
parts of the body of the user. The controller 130 may compare pitch
angles and roll angles provided from the acceleration sensors
distributed in the body parts to estimate the motion of the user.
For example, if a pitch angle and a roll angle of an acceleration
sensor attached to an elbow are kept, and a pitch angle and a roll
angle of an acceleration sensor attached to an arm are changed, the
controller 130 may determine that the arm is bent or straight.
[0046] A twinaxis or triaxis flux gate may be used in the
acceleration sensor. If the twinaxis flux gate is used,
normalization processing may be performed to map output values of X
and Y axes of the acceleration sensor to output values within a
predetermined range, and a pitch angle and a roll angle may be
calculated by using the normalized values. According to an
exemplary embodiment of the present general inventive concept, the
normalization processing may be performed according to Equation
1:
X t norm = 2 X t - ( X t max + X t min ) X t max - X t min Y t norm
= 2 Y t - ( Y t max + Y t min ) Y t max - Y t min ( 1 )
##EQU00001##
[0047] wherein Xt denotes an output value of an X axis acceleration
sensor, Yt denotes an output value of a Y axis acceleration sensor,
Xt.sub.norm denotes an output value of the X axis acceleration
sensor that has been normalized, Yt.sub.norm norm denotes an output
value of the Y axis acceleration sensor that has been normalized,
Xt.sub.max and Xt.sub.min denote maximum and minimum values of Xt,
respectively, and Yt.sub.max and Yt.sub.min denote maximum and
minimum values of Yt, respectively.
[0048] A pitch angle .theta. and a roll angle .phi. are calculated
by using Equation 2 below:
.theta. = sin - 1 ( X t norm ) .phi. = sin - 1 ( Y t norm cos
.theta. ) ( 2 ) ##EQU00002##
[0049] wherein Xt.sub.norm denotes an output value of the X axis
acceleration sensor that has been normalized, Yt.sub.norm denotes
an output value of the Y axis acceleration sensor that has been
normalized, .theta. denotes the pitch angle, and .phi. denotes the
roll angle.
[0050] The motion sensor 110 may further include a gyro sensor, a
geomagnetic sensor, etc.
[0051] The bio-signal sensor 120 senses a bio-signal of the user.
In detail, the bio-signal sensor 120 may include various types of
sensors that sense a bio-signal such as a temperature, a breathing
quantity, a resting pulse rate, a blood pressure, or the like of
the user. The breathing quantity of the user may be sensed for
example by using a microphone or a pressure sensor.
[0052] If sensed values are detected from the motion sensor 110 and
the bio-signal sensor 120, the controller 130 controls the
communicator 140 to access an external display device 200
(illustrated in FIG. 2).
[0053] The external display device 200 executes a content to
provide an exercise service to display an execution screen of the
content in order to communicate with the wearable device 100. The
external display device may be realized as various types of user
terminal devices such as for example a portable phone, a tablet PC,
a laptop computer, a desktop PC, a TV, etc. The external display
device 200 may selectively play various types of contents according
to a play command transmitted from the wearable device 100 or a
play command input through the external display device 200 or a
remote controller (not illustrated).
[0054] The communicator 140 may communicate with the external
display device 200 by using at least one of well-known
communication technologies. In detail, the communicator 140 may
include various types of chips according to exemplary embodiments
of the present general inventive concept. For example, the
communicator 140 may include at least one of various types of chips
such as a Wi-Fi chip, a Bluetooth chip, a near field communication
(NFC) chip, a wireless communication chip, etc. If a Wi-Fi chip or
a Bluetooth chip is used, the communicator 140 may transmit and
receive various types of connection information, such as a
subsystem identification (SSID), a session key, etc., with an
external device and transmit and receive various types of
information or commands after a communication connection. The
wireless communication chip performs communications according to
various types of communication standards such as Institute of
Electrical Electronics Engineers (IEEE), Gigbee, 3rd Generation
(3G), 3rd Generation Partnership Project (3GPP), Long Term
Evolution (LTE), etc. The communicator 140 may also include an
infrared (IR) lamp (not illustrated). The communicator 140 may
communicate with the external display device 200 by using these
various types of communication means.
[0055] The controller 130 transmits sensed results of the motion
sensor 110 and the bio-signal sensor 120 to the external display
device 200 to display a pose of the user on the execution
screen.
[0056] Besides the above-described sensors, various types of
sensors such as an ultrasonic proximity sensor, a pressure sensor,
a microphone sensor, a temperature sensor, etc. (not illustrated)
may be further included and used.
[0057] FIG. 2 is a view illustrating an external structure of a
wearable device 100 according to an exemplary embodiment of the
present general inventive concept. Referring to FIG. 2, the
wearable device 100 operates along with a display device 200 to
provide an exercise service. The exercise service may be
selectively determined according to a type of a content played on
the display device 200. For example, various exercise services,
such as a yoga content, a Pilates content, a golf content, a dance
content, etc., may be selected. Contents of exercises putting an
emphasis on a pose may be played. Playing of the yoga content will
now be described, but the exercise service is not limited to
yoga.
[0058] Referring to FIG. 2, the wearable device 100 includes body
parts 101 and 102 that are formed of a flexible material. The
wearable device 100 is divided into a top and bottoms, i.e., first
and second body parts 101 and 102, in FIG. 2. However, according to
exemplary embodiments of the present general inventive concept, the
wearable device 100 may be realized as all-in-one suit whose top
and bottoms are connected to each other. Alternatively, the
wearable device 100 may be realized as a band, a sticker, or the
like that may be worn on a body of a user not as a full suit
shape.
[0059] The motion sensor 110, the bio-signal sensor 120, the
communicator 140, the controller 130, etc. may be distributed in
the body parts 101 and 102.
[0060] In FIG. 2, the motion sensor 110 includes a plurality of
sensors 110-1 through 110-14 that are respectively distributed in
parts, such as joints, wrists, ankles, etc. of the body of the
user, in the body parts 101 and 102. The sensors 110-1 through
110-14 may respectively include acceleration sensors and EMG
sensors. The bio-signal sensor 120 also includes a plurality of
sensors 120-1 and 120-2. The sensors 120-1 and 120-2 of the
bio-signal sensor 120 may be distributed in positions appropriate
to sense various types of bio-signals such as a temperature, a
breathing quantity, a resting pulse rate, a blood pressure, etc. of
the user. In other words, the sensors 120-1 and 120-2 may be
distributed in proximity to the user's heart, blood vessels, neck,
etc.
[0061] The wearable device 100 transmits sensed values of the
sensors to the display device 200. The display device 200
determines a pose of the user by using the sensed values. The
display device 200 displays a reference pose image 201 and a user
pose image 202 on a screen of a content that is executed. The
reference pose image 201 is taken by a model to teach an exercise,
and the user pose image 202 is taken by the user who wears the
wearable device 100. Therefore, the user checks their pose in real
time to do exercise.
[0062] The pose of the user may be three-dimensionally displayed.
The user may check the pose by rotating the pose 360 degrees in up,
down, left, and right directions. Also, the pose of the user may be
accumulatively recorded and managed in the display device 200.
[0063] The display device 200 compares the pose of the user with a
reference pose to determine whether the user takes a normal pose.
The display device 200 provides a feedback signal to the user
according to the comparison result. The feedback signal may be
provided in various types according to exemplary embodiments of the
present general inventive concept. For example, the display device
200 may provide a vibration feedback by using a vibrator installed
in the wearable device 100, a visual feedback to display a wrong
pose on the screen, a sound feedback to output an audio signal to
signal a wrong portion of a pose through a speaker or the like, or
a combination thereof.
[0064] The display device 200 may further include a camera (not
illustrated). If the display device 200 includes the camera, the
display device 200 may capture an image of the user wearing the
wearable device 100 to use the captured image as the user pose
image 202. Here, the display device 200 may additionally display a
graphic object (not illustrated) indicating a wrong portion of the
user pose image 202 by using the captured image and the sensed
value provided from the wearable device 100.
[0065] In FIG. 2, the user seems like doing exercise with the
user's back to the display device 200, but this is only a direction
adjustment for the descriptive convenience. In general, the user
may do exercise with seeing the screen of the display device
200.
[0066] The user pose image 202 is shown like an actual image of the
user wearing the wearable device 100 in FIG. 2. However, in an
exemplary embodiment of the present general inventive concept in
which the display device 200 does not include a camera, the user
pose image 202 may be a graphic image that is arbitrarily generated
based on the values of the sensors.
[0067] FIG. 3 is a view illustrating an external structure of the
wearable device 100 to provide a vibration feedback according to an
exemplary embodiment of the present general inventive concept.
[0068] The wearable device 100 may include one or more vibrators
150. Referring to FIG. 3, the wearable device 100 illustrated
therein includes a plurality of vibrators 150-1 through 150-15 that
are distributed in regions of the body parts 101 and 102. The
controller 130 vibrates the plurality of vibrators 150-1 through
150-15 according to a feedback signal transmitted from the display
device 200 to provide a vibration feedback to the user.
[0069] The vibrators 150-1 through 150-15 may be disposed around
the motion sensors 110-1 through 110-14 in the body parts 101 and
102. In other words, the acceleration sensors and the EMG sensors
may be respectively paired with the vibrators 150-1 through 150-15.
In the exemplary embodiment of the present general inventive
concept illustrated in FIG. 3, vibrator 150-15 is not paired with a
motion sensor 110, and is discussed in detail below.
[0070] The vibrators 150-1 through 150-15 may be realized as
various types of vibrators such as a vibration motor, a
piezoelectric element, an actuator, etc. Therefore, poses of the
user may be divided according to the regions to provide vibration
feedback according to the regions. In other words, the display
device 200 compares a pose of the user with a reference pose. The
display device 200 determines a portion of the pose of the user
that does not correspond to the reference pose according to the
comparison result. The display device 200 may transmit the
comparison result to the wearable device 100.
[0071] If the pose of the user does not correspond to the reference
pose stored in a content, the controller 130 vibrates one of the
plurality of vibrators 150-1 through 150-15 corresponding to a
portion of the user's pose that does not correspond to the
reference pose in order to provide a feedback to the user.
Therefore, the user may correct a wrong portion of a pose. A
feedback strength may be different according to a disagreement
degree. In other words, the controller 130 provides a strong
vibration feedback with respect to a portion of the user's pose
having a great difference from the reference pose and a weak
vibration feedback with respect to a portion having a small
difference from the reference pose.
[0072] The controller 130 may provide a massage service to the user
by using at least one of the plurality of vibrators 150-1 through
150-15. For example, the plurality of vibrators 150-1 through
150-15 may include a vibrator, for example vibrator 150-15, that
does not provide a vibration feedback but instead relaxes muscles.
If the user finishes exercises, the controller 130 may vibrate the
particular vibrator 150-15 for a predetermined time to relax the
muscles of the user. Alternatively, when the corresponding exercise
service is executed, the controller 130 may vibrate one or more of
vibrators 150-1 through 150-15 disposed around a region of the
user's body having a large amount of movement, a region having the
greatest difference from the reference pose, or the like to relax
muscles of the corresponding region.
[0073] Front sides of the body parts 101 and 102 are illustrated in
FIGS. 2 and 3, but a vibrator 150, a motion sensor 110, a
bio-signal sensor 120, etc. may be disposed on back sides of the
body parts 101 and 102. If the wearable device 100 further includes
a body part worn on a head of the user (not illustrated), the
vibrator 150, the motion sensor 110, the bio-signal sensor 120,
etc. may be disposed on the body part worn on the head of the
user.
[0074] FIG. 4 is a block diagram illustrating a structure of a
display device 200 according to an exemplary embodiment of the
present general inventive concept. Referring to FIG. 4, the display
device 200 includes a communicator 210, a controller 220, a storage
device 230, a voice output unit 240, and a display unit 250.
[0075] The storage device 230 stores Operating System (O/S)
software to operate the display device 200, a program such as
various types of applications, various types of data input or set
when the program is executed, user pose information corresponding
to a sensed value, contents, etc.
[0076] The communicator 210 communicates with the wearable device
100 that may be worn on the body of the user. In detail, the
communicator 210 receives a sensing signal and a bio-signal of a
user motion from the wearable device 100.
[0077] The controller 220 controls an overall operation of the
display device 200. In detail, if a play command is input with
respect to the content stored in the storage device 230, the
controller 220 generates a content execution screen by using an
operator (not illustrated) and a renderer (not illustrated). The
operator calculates attribute values such as coordinate values at
which objects are to be displayed according to a layout of a
screen, shapes, sizes, and colors of the objects, etc. The renderer
generates a screen having various layouts based on the attribute
values calculated by the operator.
[0078] The contents may be contents to teach various types of
exercises such as yoga, dances, golf, Pilates, etc. In FIG. 4, the
contents stored in the storage device 230 are executed. However, if
the display device 200 is a device having a broadcast receiving
function like a TV, the contents may be contents received through a
broadcast network. Alternatively, the contents may be contents
stored on an external storage medium such as a universal serial bus
(USB) memory connected to the display device 200 or contents
recorded on a recording medium such as a digital versatile disc
(DVD), a Blu-ray disc, or the like.
[0079] The display unit 250 displays the screen generated by the
renderer. A reference pose image stored in a corresponding content
is displayed in an area of the displayed screen.
[0080] The controller 220 determines a pose of the user according
to a sensing signal and a bio-signal received from the wearable
device 100. For example, if a plurality of motion sensors 110
arranged side by side on leg parts of the user sense the same pitch
angle and roll angle, the controller 220 may determine that the
user has spread their legs. If a pitch angle sensed by a motion
sensor 110 arranged on a thigh part is 90.degree. different from a
pitch angle sensed by a motion sensor 110 arranged on a calf part,
the controller 220 determines that the user has bent their knee at
90.degree.. The controller 220 checks a breathing quantity of the
bio-signal of the user with the bio-signal sensor 120 to determine
whether the user takes a pose with breathing according to a
breathing method.
[0081] The controller 220 may realize the determined pose of the
user as an image to additionally display the image on an execution
screen. The controller 220 compares the pose of the user with the
stored reference pose.
[0082] The voice output unit 240 outputs various types of informing
sounds or voice signals related to an exercise service. The
controller 220 controls the voice output unit 240 to output the
comparison result between the pose of the user and the reference
pose as a voice. In detail, if a right leg of the user is raised up
at the back lower than the reference pose, the controller 220 may
generate a voice signal like "Raise the right leg further
backwards" and output the voice signal through the voice output
unit 240. If the user breathes hard, the controller 220 may
generate a voice signal like "Adjust breathing with keeping the
current pose" and output the voice signal through the voice output
unit 240.
[0083] The controller 220 may also display a portion of the user's
pose disagreeing with the reference pose on the execution screen
separately from the voice signal. Alternatively, the controller 220
may provide a feedback signal to transmit the comparison result to
the wearable device 100 through the communicator 210. In this case,
the wearable device 100 may provide a vibration feedback with
respect to a wrong body part by using vibrators 150 arranged on
respective parts.
[0084] Alternatively, the controller 220 may determine whether the
user takes a pose by force or an exercise is dangerous, based on a
bio-signal such as a temperature, a blood pressure, or the like of
the user. In other words, if the temperature or the blood pressure
rises or drops rapidly, the controller 220 may output a warning
message through the display unit 250 or the voice output unit 240
and transmit a warning signal to the wearable device 100 through
the communicator 210.
[0085] According to another exemplary embodiment of the present
general inventive concept, if an exercise service is ended, the
controller 220 may synthesize poses taken by the user when doing
exercise and store the synthesized poses in the storage device 230.
The controller 220 may compare a current pose of the user with
poses of the user stored when doing exercise, to accumulate and
manage an improved portion and a wrong portion of the user's
pose.
[0086] According to another exemplary embodiment of the present
general inventive concept, the display device 200 may further
include a camera and an input means (not illustrated). The camera
captures the user wearing the wearable device 100 and provides the
captured image to the controller 220. The controller 220 may
synthetically use an analyzed result of the captured image and a
motion sensing signal and a bio-signal transmitted from the
wearable device 100 to further precisely sense motions of the user.
In detail, the controller 220 divides the captured image into a
plurality of pixel blocks and compares pixel values of the pixel
blocks to first determine motions of respective body parts of the
user. In this case, the wearable device 100 may be realized so that
colors of respective parts thereof are different according to
respective body parts of the user, to further easily check the
respective body parts of the user. In other words, if the wearable
device 100 is realized so that the colors of the respective parts
thereof are different according to arms, legs, a trunk, etc. of the
user, the controller 220 may separately recognize the body parts
based on ranges of the pixel values in a process of analyzing the
pixel values
[0087] FIG. 5 is a block diagram illustrating a structure of an
exercise service providing system according to an exemplary
embodiment of the present general inventive concept. Referring to
FIG. 5, the exercise service providing system includes a wearable
device 100, a display device 200, and one or more peripheral
devices 300, illustrated in FIG. 5 as peripheral devices 300-1
through 300-n.
[0088] If a content is executed, the display device 200 transmits
an enable signal to the wearable device 100. If the content is
executed, the display device 200 generates control commands to
adjust various types of peripheral devices 300-1, 300-2, . . . ,
and 300-n to states matching with an exercise service and transmits
the control commands to the peripheral devices 300-1, 300-2, . . .
, and 300-n. The peripheral devices 300-1, 300-2, . . . , and 300-n
may include various types of home appliances such as a lighting
system, an air conditioner, a heater, a TV, an audio player,
etc.
[0089] If the user wants to do exercise such as yoga, a surrounding
environment considerably affects an exercise effect. In other
words, a disable operation may be performed to turn off or mute a
display device or an audio player except the display device 200
providing an exercise service in order to remove a sound. Also, an
operation may be performed to control the lighting system to
delicately adjust an illumination intensity and may adjust the air
conditioner and the heater to adjust a temperature appropriate to
maximize an exercise effect.
[0090] Information, such as IP addresses, identifiers, control
codes, etc. of the peripheral devices 300-1, 300-2, . . . and
300-n, may be directly registered on the storage device 230 of the
display device 200 or on a device such as a home gateway (not
illustrated). If the information is stored on the home gateway, and
a content is executed, the display device 200 transmits an exercise
service execution command to the home gateway. The home gateway
receives the exercise service execution command to transmit a
control signal to the peripheral devices 300-1, 300-2, . . . , and
300-n that have been registered, to adjust the peripheral devices
300-1, 300-2, . . . , and 300-n to environments appropriate for the
exercise service.
[0091] FIG. 6 is a flowchart illustrating an operation of an
exercise service providing system according to an exemplary
embodiment of the present general inventive concept.
[0092] Referring to FIG. 6, in operation S610, the display device
200 executes a content such as an instructional video. In operation
S620, the display device 200 transmits a start signal to the
wearable device 100. In operation S630, the wearable device 100
receives the start signal to enable a motion sensor 110 and a
bio-signal sensor 120. In other words, the wearable device 100
turns off the motion sensor 110 and the bio-signal sensor 120 and
is on standby before the content is played but turns on the motion
sensor 110 and the bio-signal sensor 120 when the content is
played.
[0093] If the sensors 110 and 120 are enabled in operation S630,
the wearable device 100 senses motions of a user by using the
sensors 110 and 120 to obtain a sensed value. In operation S640,
the wearable device 100 transmits the sensed value to the display
device 200.
[0094] In operation S650, the display device 200 determines a pose
of the user by using the sensed value. In operation S660, the
display device 200 displays the pose of the user on a screen. In
operation S670, the display device 200 compares the pose of the
user with a reference pose stored in the content. In operation
S680, the display device 200 transmits the comparison result to the
wearable device 100.
[0095] In operation S690, the wearable device 100 actuates
vibrators 150 based on the comparison result to provide a vibration
feedback. In other words, the wearable device 100 provides
vibrations to a body part disagreeing with the reference pose to
allow the user to correct their pose.
[0096] The display device 200 may adjust a playing degree of the
content according to a skill of the user. If a first pose of the
user agrees with a first reference pose over a predetermined level,
the display device 200 displays a second reference pose. If the
pose of the user does not agree with the second reference pose over
the predetermined level, the display device 200 outputs a visual
message and an audio signal to inform the user of a disagreeing
portion and order the user to correct their pose.
[0097] FIG. 7 is a flowchart illustrating an exercise service
providing method of the display device 200 according to an
exemplary embodiment of the present general inventive concept.
Referring to FIG. 7, if a content is executed, the display device
200 displays an execution screen in operation S710. In operation
S720, the display device 200 transmits a control signal which is to
adjust a peripheral device to an environment agreeing with an
exercise service before starting an exercise service.
[0098] In this state, the display device 200 provides the exercise
service according to sensor signals transmitted from the wearable
device 100.
[0099] In other words, in operation S730, the display device 200
receives a sensing signal and a bio-signal of a motion of a user
from the motion sensor 110 and the bio-signal sensor 120. In
operation S740, the display device 200 determines a pose of the
user based on the sensing signal and the bio-signal. In operation
S750, the display device 200 additionally displays the pose of the
user on the execution screen and transmits a feedback signal to the
wearable device 100. In operation S760, the display device 200
outputs a comparison result between the pose of the user and a
reference pose as a voice.
[0100] In operation S770, the display device 200 determines whether
the exercise service has been ended. The display device 200
provides the exercise service based on a sensing value of the
wearable device 100, repeating operations S730 through S760, until
it receives an ending signal to end the exercise service. The
ending signal may be input through a button of a main frame or a
remote controller (not illustrated) of the display device 200 or
when the user wearing the wearable device 100 makes a particular
motion. For example, various motions, such as a motion of the user
drawing a large circle with both hands in the air a plurality of
times, a motion of or quickly shaking the both hands, etc., may be
set to an ending motion.
[0101] When the exercise service is ended, the display device 200
transmits data about poses taken by the user in the corresponding
exercise service to a web server or other external devices (not
illustrated) in operation S780. The web server may accumulate and
manage the poses of the user to record progresses in the poses of
the user. An expert or a manager of a corresponding exercise may
access the web server to check exercise conditions of the user.
[0102] If the data is completely recorded, the display device 200
transmits a control signal to enable peripheral devices to return
to conditions before the exercise service in operation S790.
[0103] As described above, a wearable device is formed of a
flexible material to be worn by a user. In this case, a battery 160
may be formed of a flexible material like the wearable device.
[0104] FIG. 8 is a view illustrating a structure of a wearable
device 100 including a flexible power supply device 160 such as a
battery according to another exemplary embodiment of the present
general inventive concept.
[0105] The flexible power supply device 160 may include a primary
battery and a secondary battery (not illustrated). Referring to
FIG. 8, a plurality of line batteries 160-1, 160-2, 160-3, . . . ,
and 160-x are connected to one another in series to form one line,
and formed lines intersect with one another to form a fabric. The
flexible power supply device 160 is arranged in a part of a first
body part 101 in FIG. 8, but a whole part of the wearable device
100 may be realized as the flexible power supply device 160. In
other words, as illustrated in FIG. 8, a plurality of line
batteries 160-x having flexible characteristics may be connected to
one another to form a fabric structure having a suit shape
supporting elements such as various types of sensors, a controller,
etc.
[0106] FIG. 9 is a view illustrating an internal structure of one
line battery 160-x according to an exemplary embodiment of the
present general inventive concept. Referring to FIG. 9, the line
battery 160-x is realized as a shape in which an internal current
collector 1, an internal electrode 2, an electrolyte part 3, an
external electrode 4, an external current collector 5, and a
coating 6 are arranged sequentially from an inside of the line
battery 160-x.
[0107] The internal current collector 1 may be formed of an alloy
such as TiNi having a high elastic characteristic, a carbon fiber,
other conductive polymers, or the like. A surface of the internal
current collector 1 is covered with the internal electrode 2. The
internal electrode 2 may be formed of various types of materials
according to a characteristic thereof. If the internal electrode 2
is used as a negative electrode, the internal electrode 2 may be
formed of a negative electrode material such as lithium, natrium,
or the like. In this case, the external electrode 4 is used as a
positive electrode and thus may be formed of a positive electrode
material such as sulfur (S), metal sulfide, or the like. If the
internal electrode 2 is used as a positive electrode, and the
external electrode 4 is used as a negative electrode, the internal
electrode 2 may be formed of a positive electrode material, and the
external electrode 4 may be formed of a negative electrode
material. A surface of the internal electrode 2 is covered with the
electrolytic part 3. The electrolytic part 3 physically isolates
the internal and external electrodes 2 and 4 from each other so as
to exchange ions between the internal and external electrodes 2 and
4. The electrolytic part 3 may be realized in various forms such as
a gel form, a porous form, a solid state form, etc. The external
electrode 4 is disposed on an outer side of the electrolytic part
3, and the external current collector 5 is disposed on an outer
side of the external electrode 4. The external current collector 5
may be formed of various materials like the internal current
collector 1 that has been described above. The coating 6 is formed
on an outer side of the external current collector 5. The coating 6
may be formed of a general polymer resin. For example, polyvinyl
chloride (PVC), an epoxy resin, or the like may be used. Any
material that prevents damage to a thread-shape battery and is
freely bent or crooked may be used as the coating 6. The structure
of the line battery 160-x of FIG. 9 is only an example and thus is
not limited thereto.
[0108] As described above, a user uses various exercise services by
using a wearable device 100 and a display device 200. The wearable
device 100 is used to precisely sense motions of the user and
analyze bio-signals of the user in order to support the user in
obtaining an exact exercise effect without overdoing exercise.
[0109] Various types of elements such as various types of sensors
attached onto the wearable device 100 may be attached onto or
detached from the wearable device 100.
[0110] According to various exemplary embodiments of the present
general inventive concept as described above, a wearable device 100
that a user wears senses a motion and a bio-signal of the user to
determine a pose of the user. Therefore, the wearable device 100
provides a feedback appropriate for the pose of the user so as to
maximize an exercise effect.
[0111] Although exemplary embodiments of the present general
inventive concept described above are directed to using the
wearable device 100 to maximize an exercise effect, the present
general inventive concept is not limited to exercise applications.
The present general inventive concept may for example also be
applied to security, comparing the user's pose to a reference pose
to determine a security clearance of the user. The present general
inventive concept may also be applied for example to medical and
therapeutic purposes, comparing a patient's pose to a reference
pose so that the patient maintains a pose best suited to recovery
or long-term health.
[0112] The present general inventive concept can also be embodied
as computer-readable codes on a computer-readable medium. The
computer-readable medium can include a computer-readable recording
medium and a computer-readable transmission medium. The
computer-readable recording medium is any data storage device that
can store data as a program which can be thereafter read by a
computer system. Examples of the computer-readable recording medium
include a semiconductor memory, a read-only memory (ROM), a
random-access memory (RAM), a USB memory, a memory card, a Blu-Ray
disc, CD-ROMs, magnetic tapes, floppy disks, and optical data
storage devices. The computer-readable recording medium can also be
distributed over network coupled computer systems so that the
computer-readable code is stored and executed in a distributed
fashion. The computer-readable transmission medium can transmit
carrier waves or signals (e.g., wired or wireless data transmission
through the Internet). Also, functional programs, codes, and code
segments to accomplish the present general inventive concept can be
easily construed by programmers skilled in the art to which the
present general inventive concept pertains.
[0113] Although a few embodiments of the present general inventive
concept have been shown and described, it will be appreciated by
those skilled in the art that changes may be made in these
embodiments without departing from the principles and spirit of the
general inventive concept, the scope of which is defined in the
appended claims and their equivalents.
