Referring to FIG. 1, the system 100 for human body communication may include an electronic device 120 which contacts a body of a user 110, and exercise equipment 130.

According to one example embodiment, the electronic device 120 may transmit authentication information through the body of the user 110 when the electronic device 102 is contacted by the skin of the user 110. For example, when the electronic device 120 (e.g., a wearable electronic device) is contacted by the skin of the user 110, the electronic device 120 may determine whether a motion of the user 110 is detected. When the motion of the user 110 is detected through a motion sensor, the electronic device 120 may transmit authentication information of the corresponding user through the body of the user 110 which is in contact with the electronic device 120. For example, the electronic device 120 may periodically transmit user's authentication information. For example, the authentication information may include at least one piece of user information, and the user information may include at least one of a membership number, a portion of a resident registration number, a phone number, an identification (ID), vein (blood vessel) information, age, and a name, or information of a combination of at least one of the aforementioned pieces of information.

According to one embodiment, when contact (touch) of the user 110 is detected, the exercise equipment 130 may receive authentication information through the body of the user 110. The exercise equipment 130 may authenticate the user using the authentication information received through the body of the user 110. For example, when user authentication is successful, the exercise equipment 130 may collect exercise information of the corresponding user and may transmit the exercise information to the electronic device 120 or a management device (not shown). According to one example embodiment, when generation of an authentication event is detected based on contact information of the user 110, the exercise equipment 130 may transmit an authentication information request signal to the electronic device 120 through the body of the user 110. The exercise equipment 130 may receive authentication information through the body of the user 110 in response to the authentication information request signal.

FIG. 2A is a view illustrating an electronic device 201 according to various example embodiments of the present disclosure. In the following description, the electronic device 201 may include the electronic device 120 of FIG. 1.

Referring to FIG. 2A, the electronic device 201 may include a bus 210, a processor 220, a memory 230, an input/output (I/O) interface 250, a display 260, a communication interface 270, and a sensor 280. According to certain example embodiments, the electronic device 201 may omit at least one of the above-described elements or may further include other element(s) (not shown).

The bus 210 may interconnect the above-described elements 220 to 280, and may include circuitry for conveying communications (for example, a control message and/or data) between and among the above-described elements.

The processor (e.g., processing circuitry) 220 may include one or more of a central processing unit (CPU), an application processor (AP), an image signal processor (ISP), or a communication processor (CP). The processor 120 may perform, for example, operations or data processing associated with control and/or communication of at least one other element(s) of the electronic device 201.

According to one embodiment, the processor 220 may control transmitting authentication information of the electronic device 201 to an external device (e.g., electronic device 204 such as exercise equipment) through a body 272 of a user (for example, the user 110 of FIG. 1) which is in contact with the electronic device 201 and with the external device. For example, when contact with a body of a user is detected through an electrode of the communication interface 270, the processor 220 may control the communication interface 270 to transmit user authentication information of the electronic device 201, which is stored in the memory 230, to the external device 204 through the body 272 of the user. According to one example embodiment, the processor 220 may control the communication interface 270 to periodically transmit the user's authentication information for a pre-defined time. For example, the user's authentication information may include at least one of user's identification information (for example, a phone number), application identification information, unique identification information (for example, membership information) allocated to the user in a specific place, and a certain value.

According to one example embodiment, the processor 220 may control transmitting the authentication information of the electronic device 201 to the external device 204 through the body 272 of the user based on motion information of the user who is in contact with the electronic device 201. For example, when the electronic device 201 detects contact with a body of a user, the processor 220 may determine whether a user's motion is made using sensor data received from the sensor 280. When the user's motion is detected, the processor 220 may control transmitting the user authentication information of the electronic device 201 to the external device 204 through the body 272 of the user. For example, the user's motion may include motion greater than or equal to a pre-determined amount of motion.

According to one example embodiment, the processor 220 may control transmitting the authentication information of the electronic device 201 to the external device through the body 272 of the user based on a request of electronic device 204 (e.g., exercise equipment). For example, when the electronic device 201 detects contact with a body of a user, the processor 220 may determine whether an authentication information request signal of the exercise equipment is received. When the authentication information request signal is received through the communication interface 270, the processor 220 may control transmitting the user authentication information of the electronic device 201 to the exercise equipment through the body 272 of the user.

According to one example embodiment, the processor 220 may control transmitting exercise information of a user to the exercise equipment. For example, when identification information of the exercise equipment by which the user is authenticated is acquired, the processor 220 may determine a recommended exercise program in the corresponding exercise equipment based on at least one of personal information and an exercise history of the user. The processor 220 may control transmitting the recommended exercise program information to the exercise equipment through the body 272 of the user. For example, the personal information may include, without limitation, at least one of age, sex, biometric information, and a disease history of the user. According to one example embodiment, the processor 220 may control the memory 230 to map the identification information of the exercise equipment and the recommended exercise program information and store the mapped information.

According to one example embodiment, the processor 220 may collect a user's biometric information. For example, when authentication success information for a user is received from the exercise equipment, the processor 220 may collect a user's biometric change information through at least one sensor which is in contact with the body 272 of the user. For example, the biometric change information may include, without limitation, at least one of a heartbeat, blood pressure, and oxygen saturation.

According to one example embodiment, the processor 220 may control output of a user's exercise information. For example, when the user's exercise information is received from the exercise equipment through the body 272 of the user or through wireless resources (e.g., via a management device such as electronic device 202 via wireless communication links 274 and 275), the processor 220 may control to display the user's exercise information through a display electrically connected with the electronic device 201. The processor 220 may alternatively or additional control output of the exercise information through sound(s). For example, the exercise information received from the exercise equipment may include, without limitation, at least one piece of information of an exercise time, number of times of exercising, a distance, and burned calories, as a portion of the exercise information detected by the exercise equipment.

The memory 230 may include a volatile memory and/or nonvolatile memory. The memory 230 may store, for example, instructions or data associated with at least one other element(s) of the electronic device 201. For example, the memory 230 may store a user's personal information and a user's exercise history. For example, the memory 230 may map identification information of exercise equipment which is contacted by a user and recommended exercise program information transmitted to the corresponding exercise equipment, and may store the mapped information. For example, the memory 230 may map identification information of exercise equipment which is contacted by a user and exercise information provided from the corresponding exercise equipment, and may store the mapped information. According to one example embodiment, the memory 230 may store software and/or a program(s) 240. The program(s) 240 may include, for example, a kernel 241, middleware 243, an application programming interface (API) 245, and/or an application program (or an “application”) 247. At least a portion of the kernel 241, the middleware 243, and/or the API 245 may be called an operating system. The kernel 241 may control or manage system resources (for example, the bus 210, the processor 220, the memory 230, or the like) that are used to execute operations or functions of other programs (for example, the middleware 243, the API 245, and/or the application program 247). Furthermore, the kernel 241 may provide an interface that allows the middleware 243, the API 245, and/or the application program 247 to access discrete elements of the electronic device 201 so as to control or manage system resources.

The middleware 243 may perform a mediation role such that the API 245 or the application program 247 communicates with the kernel 241 to exchange data. Furthermore, the middleware 243 may process one or more task requests received from the application program 247 according to a priority. For example, the middleware 243 may assign the priority, which makes it possible to use a system resource (for example, the bus 210, the processor 220, the memory 230, or the like) of the electronic device 201, to at least the application program 247, and may process the one or more task requests. The API 245 may be an interface through which the application program 247 controls a function provided by the kernel 241 or the middleware 243, and may include, for example, at least one interface or function (for example, an instruction) for file control, window control, image processing, character control, or the like.

The input/output (I/O) interface (e.g., input/output interface circuitry) 250 may transmit an instruction or data, inputted from a user or another external device, to other element(s) of the electronic device 201, or may output an instruction or data, received from other element(s) of the electronic device 201, to the user or another external device.

The display 260 may include, for example, a liquid crystal display (LCD) (e.g., an IPS LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display 260 may display, for example, various contents (for example, text, image(s), video, icon(s), and/or symbol(s)) to a user. The display 260 may include a touch screen and may receive, for example, a touch, a gesture, proximity, or hovering input using an electronic pen or a portion of a user's body. For example, the display 260 may display exercise information provided from exercise equipment or user's biometric change information detected by the processor 220.

The communication interface (e.g., communication interface circuitry) 270 may establish communication between the electronic device 201 and an external device (for example, the external electronic device 202, external electronic device 204 and/or other external devices such as a server). For example, the communication interface 270 may perform communication with an external device (for example, the external electronic device 204 such as exercise equipment) by the medium of a user's body through an electrode which is in contact with the user's body. For example, the communication interface 270 may communicate with an external device (for example, a second external electronic device 202 or a server) through wireless communication or wired communication. For example, with reference to FIG. 2A, electronic device 201 may communicate with electronic device 204 via an electronic device 202 (e.g., a management device) over wireless communication links 274 and 275. For example, certain exercise information at the end of an exercise session may be sent from electronic device 204 (exercise equipment) to management device 202. Management device 202 may store this exercise information and communicate some or all of this information to electronic device 201.

According to one example embodiment, the wireless communication may include, without limitation, cellular communication using at least one of, for example, long term evolution (LTE), LTE Advanced (LTE-A), code division multiple access (CDMA), wideband CDMA (WCDMA), universal mobile telecommunications system (UMTS), wireless broadband (WiBro), global system for mobile communications (GSM), or the like.

According to one example embodiment, the wireless communication may include, for example, at least one of wireless fidelity (WiFi), Bluetooth, Bluetooth low energy (BLE), Zigbee, near field communication (NFC), magnetic secure transmission, radio frequency (RF), or a body area network (BAN). According to one example embodiment, the wireless communication may include, without limitation, global navigation satellite system (GNSS). The GNSS may include, for example, global positioning system (GPS), global navigation satellite system (Glonass), BeiDou navigation satellite system (hereinafter, referred to as “BeiDou”) or Galileo (the European global satellite-based navigation system). Hereinafter, “GPS” and “GNSS” may be interchangeably used in the present disclosure. The wired communication may include, without limitation, at least one of, for example, a universal serial bus (USB), a high-definition multimedia interface (HDMI), a recommended standard-232 (RS-232), power line communication, or a plain old telephone service (POTS).

Each of the first and second external electronic devices 202 and 204 may be the same or different type of device as or from the electronic device 201. In one non-limiting example embodiment, electronic device 201 is a wearable electronic device (e.g., an electronic watch), electronic device 204 is exercise equipment such as a treadmill, elliptical machine, stationary bicycle, weight machine, free weights, and the like, and electronic device 202 is a management device such as a smart phone. According to various example embodiments, all or a part of operations that the electronic device 201 will perform may be executed by another or plural other electronic devices (for example, the electronic devices 202 and 204 and/or a server). According to one example embodiment, in a case in which the electronic device 201 executes any function or service automatically or in response to a request, the electronic device 201 may not perform the function or the service internally, but, alternatively or additionally, it may request at least a portion of a function associated with the electronic device 201 at another device (for example, the electronic device 202 or 204 and/or a server (not shown)). The other electronic device (for example, the electronic device 202 or 204 or a server) may execute the requested function or additional function and may transmit the execution result to the electronic device 201. The electronic device 201 may provide the requested function or service using the received result or may additionally process the received result to provide the requested function or service. To achieve this, for example, cloud computing, distributed computing, or client-server computing may be used.

The sensor 280 may include at least one sensor and associated circuitry for measuring a physical quantity corresponding to, for example and without limitation, the electronic device 201 or detecting a motion state of the electronic device 201, or for detecting a user's biometric information. The sensor 280 may further include a control circuit for controlling the at least one sensor.

According to various example embodiments, as shown in FIG. 2B, exercise equipment may include a bus 210′, a processor 220′, a memory 230′, an input/output interface 250′, a display 260′, a communication interface 270′, and a sensor 280′ arranged in a similar configuration to the components of the electronic device 201 of FIG. 2A. In a certain example embodiments, the exercise equipment may omit at least one of the elements or may further include other element(s).

According to one example embodiment, the processor 220′ of the exercise equipment may receive a user's authentication information through the body 272 of a user (for example, the user 110 of FIG. 1) which is in contact with the exercise equipment. For example, when user's body contact with the exercise equipment is detected through an electrode electrically connected with the communication interface 270′ of the exercise equipment, the processor 220′ of the exercise equipment may activate at least a portion (for example, a human body communication module including communication circuitry) of the communication interface 270′ of the exercise equipment for human body communication. The processor 220′ of the exercise equipment may receive a user's authentication number (and/or other information) through the activated human body communication module.

According to one example embodiment, the processor 220′ of the exercise equipment may control transmitting identification information of the exercise equipment to an external device (for example, the electronic device 201) through the body 272 of the user (for example, the user 110 of FIG. 1) which is in contact with the exercise equipment. For example, when authentication succeeds using the user's authentication information provided from the external device 201, the processor 220′ of the exercise equipment may transmit identification information (for example, an ID) of the exercise equipment to the external device 201 through the body 272 of the user that is in contact with the exercise equipment. For example, the processor 220′ of the exercise equipment may determine whether an identification information transmission event is generated based on user's body contact information. When the identification information transmission event is generated, the processor 220′ of the exercise equipment may transmit the identification information (for example, the ID) of the exercise equipment to the external device 201 through the body 272 of the user which is in contact with the exercise equipment. According to one example embodiment, when authentication of the user succeeds using the user's authentication information, the processor 220′ of the exercise equipment may determine whether the identification information transmission event is generated. For example, the processor 220′ of the exercise equipment may determine whether the identification information transmission event is generated based on at least one of the number of times the user contacts the exercise equipment and a contact holding time.

According to one example embodiment, when the user of the external device is authenticated, the processor 220′ of the exercise equipment may detect exercise information corresponding to the corresponding user. For example, the processor 220′ of the exercise equipment may receive recommended exercise program information of the corresponding user through the body 272 of the user that is in contact with the exercise equipment. For example, as described above, the processor 220 of electronic device 201 may determine a recommended exercise program of the corresponding user based on an exercise history of the corresponding user which is stored in the memory 230. According to another embodiment, the processor 220′ may determine recommended exercise program information corresponding to the user of the external device 204 through a management device (for example, the electronic device 202) or may generate the recommended exerciser program information itself. For example, the recommended exercise program information may include at least one of a course of an exercise to be performed through the exercise equipment, the number of times of exercising, a weight, and an exercise time.

According to one example embodiment, the processor 220′ of the exercise equipment may detect a user's exercise information using a sensor of the exercise equipment. For example, when the authentication of a user who is in contact with the exercise equipment succeeds, the processor 220′ of the exercise equipment may recognize that the corresponding user starts exercising, and may collect a user's exercise information. For example, the processor 220′ of the exercise equipment may determine whether an exercise start event is generated based on body contact information of the user who is authenticated using the authentication information provided through the body 272 of the user. When the exercise start event is generated, the processor 220′ of the exercise equipment may recognize that the corresponding user starts exercising and may collect the user's exercise information. For example, the processor 220′ of the exercise equipment may determine whether the exercise start event is generated based on at least one of the number of times the user contacts the exercise equipment and a contact holding time. For example, when the user is authenticated using the authentication information provided through the body 272 of the user, the processor 220′ of the exercise equipment may determine whether an input to an exercise button is detected. When the input to the exercise button is detected, the processor 220′ of the exercise equipment may recognize that the user starts exercising and may collect the user's exercise information.

According to one example embodiment, the processor 220′ of the exercise equipment may continuously detect user's exercise information until an exercise end time of the user on the exercise equipment. For example, when the user's contact with the exercise equipment is maintained, the processor 220′ of the exercise equipment may recognize that the user is exercising and may continuously collect a user's exercise information. That is, when the user's contact with the exercise equipment is released, the processor 220′ of the exercise equipment may determine that the user's exercise is finished. For example, when user's contact is detected again before a reference time elapses from the time that the user's contact with the exercise equipment is released, the processor 220′ of the exercise equipment may recognize that the user is exercising and may continuously collect a user's exercise information. That is, when user's contact with the exercise equipment is not detected even after the reference time elapses, the processor 220′ of the exercise equipment may determine that the user's exercise is finished. For example, when user's exercise information is collected through authentication of the user who is in contact with the exercise equipment, the processor 220′ of the exercise equipment may determine whether an input to an exercise button to finish or stop exercising is detected.

For example, when the user's exercise is finished, the processor 220′ of the exercise equipment may determine whether the user's contact with the exercise equipment is maintained. When the user's contact with the exercise equipment is detected, the processor 220′ of the exercise equipment may control transmitting at least a portion of the user's exercise information to the external device through the body 272 of the user. For example, when the user's exercise is finished, the processor of the exercise equipment may control transmitting the user's exercise information to a management device 202.

For example, when body contact of the user is detected (622), the exercise equipment 610 may transmit the authentication request signal to the electronic device 600 by the medium of the body of the user. In response to the authentication request signal, the exercise equipment 610 may receive the authentication information of the electronic device 600 by the medium of the body of the user. The exercise equipment 610 may authenticate the electronic device 600 by comparing the authentication information of the electronic device 600 and reference information already registered for user authentication. When the authentication of the electronic device 600 succeeds, the exercise equipment 610 may transmit the result of authentication (for example, success) to the electronic device 600 through the body of the user (627).

According to one example embodiment, when the authentication of the electronic device 600 succeeds, the exercise equipment 610 may collect user's exercise information (629). For example, the exercise equipment 610 may detect user's exercise information based on driving information (motion information) of the exercise equipment 610 driven by the user.

According to one embodiment, the exercise equipment 610 may transmit the exercise information to the electronic device 600 through the body of the user (631). For example, when the user's body contact is maintained, the exercise equipment 610 may periodically transmit the user's exercise information to the electronic device 600 through the body of the user. For example, the exercise equipment 610 may extract at least a portion (for example and without limitation, at least one of an exercise time, the number of times of exercising, a distance, and burned calories) of the user's exercise information collected at the exercise equipment 610, and may transmit the extracted information to the electronic device 600.

According to one example embodiment, the electronic device 600 may store the exercise information received from the exercise equipment 610 through the body of the user (633). For example, the electronic device 600 may output the exercise information received from the exercise equipment 610 to the outside (634). For example, the electronic device 600 may output the exercise information in the form of at least one of graphic, a sound, and a vibration.

According to one embodiment, when the end of the user's exercise is detected (635), the exercise equipment 610 may collect the result of exercising and transmit the result to the electronic device 600 (637). For example, when the body contact of the user is not detected even after a reference time elapses or an input to an end button is detected, the exercise equipment 610 may determine that the user's exercise is finished. For example, the exercise equipment 610 may transmit the user's exercise information to the electronic device 600 using the body of the user and/or using radio resources.

According to one example embodiment, the electronic device 600 may output the exercise information received from the exercise equipment 610 to the outside (639).

FIG. 6B is a flowchart for transmitting authentication information in an electronic device according to various example embodiments of the present disclosure. In the following description, the electronic device may include the electronic device 201 of FIG. 2 or at least a portion (for example, the processor 220) of the electronic device 201.

Referring to FIG. 6B, in operation 601, the electronic device may detect body contact with a user. For example, the processor 220 may determine whether a body of the user contacts the electronic device based on a current change (or a change in a resistance value) detected through an electrode which is electrically connected to the communication interface 240 and leads to the surface of the electronic device 201.

In operation 603, the electronic device may detect a motion made by the user who is in contact with the electronic device. For example, the processor 220 may determine whether a motion of the electronic device 201 is detected through the sensor 280 while the user's body contact is maintained. When a motion greater than or equal to a reference size is detected through the sensor 280 while the user's body contact is maintained, the processor 220 may determine that the electronic device 201 is worn on the user.

When it is determined that the electronic device is worn on the user, the electronic device may transmit authentication information through the body of the user in operation 605. For example, the processor 220 may control the communication interface 270 (for example, the human body communication module) to transmit user's identification information pre-stored in the memory 230 through a body 272 of the user which is in contact with the electronic device 201. For example, when it is determined that the electronic device 201 is worn on the user, the processor 220 may activate at least a portion (for example, the human body communication module) of the communication interface 270 for performing human body communication. For example, the processor 220 may activate at least a portion (for example, the human body communication module) of the communication interface 270 for performing human body communication based on situation information of the electronic device 201. The situation information of the electronic device 201 may include at least one of a place (for example, a location of the electronic device 201), a person (for example, a person wearing the electronic device 201), a thing, and equipment.

In operation 607, the electronic device may collect biometric information obtained during a user's exercise. For example, when the user's authentication information is transmitted to an external device (for example, exercise equipment) by the medium of the body 272 of the user, the processor 220 may collect biometric change information of the user through the at least one sensor 280. According to one example embodiment, when authentication success information is received from the external device through the body 272 of the user, the processor 220 may collect biometric change information (e.g., pulse rate) of the user through the at least one sensor 280. For example, the processor 220 may estimate (detect) an amount of exercise of the user based on the biometric change information.

According to various example embodiments of the present disclosure, when contact with the body of the user is detected, the electronic device may transmit authentication information through the body of the user based on body contact information. For example, the processor 220 may detect body contact with the user. The processor 220 may transmit authentication information stored in the memory 230 to an external device through the body 272 of the user which is in contact with the electronic device 201.

FIG. 7 is a flowchart of an example for transmitting authentication information through human body communication in an electronic device according to various example embodiments of the present disclosure. In the following description, operation 605 in FIG. 6 of transmitting authentication information through a human body will be described. In the following description, the electronic device may include the electronic device 201 of FIG. 2 or at least a portion (for example, the processor 220) of the electronic device 201.

Referring to FIG. 7, when a motion of the electronic device made by a user is detected while the electronic device is contacted by a body of the user (for example, operation 603 of FIG. 6), the electronic device may transmit authentication information through the body of the user which is in contact with the electronic device in operation 701. For example, the processor 220 may transmit authentication information for identifying the user (or the electronic device 201), which is stored in the memory 230, through human body communication using the body 272 of the user contacting the electronic device 201 as a medium. For example, the authentication information may include at least one of user's unique identification information (for example, a phone number), application identification information, unique identification information (for example, membership information) allocated to a user in a specific place, and a certain value.

In operation 703, the electronic device may determine whether a reference time elapses from an initial time that the authentication information is transmitted using the body of the user. For example, when the authentication information is initially transmitted through the body of the user, the processor 220 may activate a first timer which is driven for a reference time. The processor 220 may determine whether the driving time of the first timer expires. For example, the driving of the first timer may be finished or extinguished when the reference time comes.

When the reference time does not elapse from the initial time that the authentication information is transmitted using the body of the user, the electronic device may determine whether an authentication information transmission period comes in operation 705. For example, when the authentication information is transmitted through the body of the user, the processor 220 may activate a second timer which is driven during the authentication information transmission period. The processor 220 may determine whether the driving time of the second timer expires. For example, the second timer may be reset when the processor 220 transmits the authentication information.

When the authentication information transmission period does not come, the electronic device may determine again whether the reference time elapses from the initial time that the authentication information is transmitted using the body of the user in operation 703.

When the authentication information transmission period comes, the electronic device may transmit the authentication information through human body communication using the body of the user which is in contact with the electronic device.

When the reference time elapses from the initial time that the authentication information is transmitted using the body of the user, the electronic device may finish transmitting the authentication information.

According to various example embodiments, when a response signal to the authentication information is received from an external device through human body communication, the electronic device may finish transmitting the authentication information. For example, the processor 220 may periodically control transmitting the authentication information through the body 272 of the user which is in contact with the electronic device 201 (for example, operations 701 and 705 of FIG. 7). When the response signal to the authentication information is received from exercise equipment (for example, the electronic device 204 of FIG. 2) through the body 272 of the user who contacts the electronic device 201, the processor may determine that authentication of the electronic device 201 is completed. For example, the response signal to the authentication information may include identification information of the exercise equipment which is contacted by the user.

FIG. 8 is a flowchart of another example for transmitting authentication information through human body communication in an electronic device according to various example embodiments of the present disclosure. In the following description, operation 605 in FIG. 6 of transmitting authentication information through a human body will be described. In the following description, the electronic device may include the electronic device 201 of FIG. 2 or at least a portion of the electronic device 201 (for example, the processor 220).

Referring to FIG. 8, when a motion of the electronic device made by a user is detected while the electronic device is contacted by a body of the user (for example, operation 603 of FIG. 6), the electronic device may determine whether an authentication request signal is received through the body of the user which is in contact with the electronic device in operation 801. For example, the processor 220 may determine whether an authentication request signal is received from an external device (for example, exercise equipment) through human body communication using the body 272 of the user which is in contact with the electronic device 201 as a medium.

When the authentication request signal is received through the body of the user which is in contact with the electronic device, the electronic device may transmit authentication information through the body of the user in operation 803. For example, the processor 220 may control transmitting a user's authentication information (or authentication information of the electronic device 201) stored in the memory 230 to the external device through the body 272 of the user which is in contact with the electronic device 201.

In operation 805, the electronic device may determine whether a response signal to the authentication information transmitted through the body of the user is received. For example, the processor 220 may determine whether a response signal to the authentication information is received from the external device (for example, exercise equipment) through human body communication using the body 272 of the user which is in contact with the electronic device 201 as a medium. For example, the response signal to the authentication information may include information on whether the authentication succeeds and identification information of the external device.

When the response signal to the authentication information transmitted through the body of the user is not received, the electronic device may determine whether an authentication information transmission period comes in operation 807. For example, the processor 220 may determine whether a driving time of a timer driven based on transmission of authentication information using the body 272 of the user expires. When the driving time of the timer expires, the processor 220 may determine that the authentication information transmission period comes. For example, the timer may be reset when the processor 220 transmits the authentication information through the body 272 of the user.

When the authentication information transmission period does not come, the electronic device may determine again whether a response signal to the authentication information transmitted through the body of the user is received in operation 805.

When the authentication information transmission period comes, the electronic device may transmit the authentication information again through the body of the user which is in contact with the electronic device.

When the response signal to the authentication information transmitted through the body of the user is received, the electronic device may finish transmitting the authentication information. For example, when the response signal to the authentication information is received from the external device through the body 272 of the user which is in contact with the electronic device 201, the processor 220 may determine that the authentication of the electronic device 201 is completed. Accordingly, the processor 220 may finish transmitting the authentication information using the body of the user.

FIG. 9 is a flowchart for managing biometric information and exercise information of a user in an electronic device according to various example embodiments of the present disclosure. In the following description, operation 607 in FIG. 6 of collecting user's biometric information will be described. In the following description, the electronic device may include the electronic device 201 of FIG. 2 or at least a portion of the electronic device 201 (for example, the processor 220).

Referring to FIG. 9, when a user's authentication information (or authentication information of the electronic device) is transmitted through a body of the user which is in contact with the electronic device (for example, operation 605 of FIG. 6), the electronic device may determine whether authentication of the user succeeds in an external device in operation 901. For example, when the user's authentication information is transmitted to an external device (for example, exercise equipment) through the body 272 of the user which is in contact with the electronic device 201, the processor 220 may determine whether a response signal to the authentication information is received from the external device. When the response signal to the authentication information is received through the body 272 of the user which is in contact with the electronic device 201, the processor 220 may determine whether the authentication of the user succeeds based on the response signal. For example, when the response signal to the authentication information includes identification information of the external device, the processor 220 may determine that the authentication of the user succeeds in the external device.

When the authentication of the user succeeds in the external device, the electronic device may transmit recommended exercise information corresponding to the user to the external device in operation 903. For example, when the authentication of the user succeeds in the external device, the processor 220 may extract at least one of user's personal information and a user's exercise history from the memory 230. The processor 220 may determine a recommended exercise program corresponding to at least one of the user's personal information and the user's exercise history and the identification information of the external device. The processor 220 may transmit the recommended exercise program information to the external device (for example, exercise equipment) through the body 272 of the user which is in contact with the electronic device 201. For example, the personal information may include at least one of age, sex, biometric information, and a disease history of the user. According to one example embodiment, the processor 220 may map the identification information of the external device and the recommended exercise program information, and may store the mapped information in at least a region of the memory 230.

In operation 905, the electronic device may detect user's biometric change information. For example, when the recommended exercise information is transmitted, the processor 220 may determine that a user's exercise starts. Accordingly, the processor 220 may collect user's biometric change information according to the recommended exercise information using at least one sensor 280 contacting the body of the user. For example, the biometric change information may include change information of at least one of a heartbeat, blood pressure, and oxygen saturation.

In operation 907, the electronic device may determine whether exercise information is received from the external device. For example, the processor 220 may determine whether exercise information is received through the body 272 of the user contacting the electronic device by means of an electrode electrically connected to the communication interface 240.

When the exercise information is not received from the external device, the electronic device may continuously detect user's biometric change information in operation 905. For example, when user's biometric data is not changed even after a reference time elapses or is continuously stabilized for the reference time, the processor 220 may determine that the user's exercise is finished.

When the exercise information is received from the external device, the electronic device may match the user's biometric change information and the exercise information and store the matched information in operation 909. For example, when the exercise information is received through the body 272 of the user contacting the electronic device by means of the electrode electrically connected to the communication interface 240, the processor 220 may match the user's biometric change information which is collected through the at least one sensor 280 at a corresponding time and the exercise information, and may store the matched information in the memory 230. For example, the exercise information may include information of at least one of an exercise time, the number of times of exercising, a distance, and burned calories as at least a portion of the exercise information detected at the external device (for example, exercise equipment).

FIG. 10 is a flowchart for detecting motion information of a user in exercise equipment according to various example embodiments of the present disclosure.

Referring to FIG. 10, the exercise equipment may detect body contact of a user in operation 1001. For example, the processor 220 may detect contact of the body 272 of the user through an electrode (for example, a handle) leading from the communication interface 270′ to the surface of the exercise equipment. According to one example embodiment, the processor 220′ may determine whether an authentication event is generated based on body contact information which is detected through the electrode (for example, the handle) leading from the communication interface 270′ to the surface of the exercise equipment. When it is determined that the authentication event is generated, the processor 220′ may determine that contact for a user's exercise is generated. For example, the body contact information may include at least one of the number of times the user contacts for a reference time and a contact holding time.

In operation 1003, the exercise equipment may determine whether authentication information is received through the body of the user which is in contact with the exercise equipment. For example, the processor 220′ may determine whether authentication information of the electronic device (for example, the electronic device 201 of FIG. 2) is received through the body 272 of the user which is in contact with the exercise equipment.

When the authentication information is received through the body of the user which is in contact with the exercise equipment, the exercise equipment may determine whether the user corresponding to the authentication information received through the body of the user can be authenticated in operation 1005. For example, the processor 220′ may compare the authentication information received through the body 272 of the user and at least one piece of reference information pre-stored in the memory 230′. When there exists reference information matching the authentication information received through the body 272 of the user, the processor 220′ may determine that the authentication of the user corresponding to the authentication information succeeds. According to one example embodiment, when the authentication of the user succeeds, the processor 220′ may control the display 260′ to display user information.

When the user corresponding to the authentication information is not authenticated, the exercise equipment may determine not to support an exercise service for the corresponding user. In this case, the exercise equipment may be driven by a user's operation on a button, but may put a limit to providing an exercise service such as automatically setting a recommended exercise program and collecting exercise information through human body communication.

When the authentication of the user corresponding to the authentication information received through the body of the user succeeds, the exercise equipment may detect motion information according to a user's exercise in operation 1007. For example, when the authentication of the user corresponding to the authentication information received through the body 272 of the user succeeds, the processor 220′ may determine to support an exercise service for the corresponding user. The processor 220′ may determine a recommended exercise program corresponding to the user. For example, the processor 220′ may receive recommended exercise program information through the body 272 of the user which is in contact with the exercise equipment. For example, the processor 220 of the electronic device may determine a recommended exercise program based on at least one of an exercise history and personal information, which corresponds to the successfully authenticated user and is detected from the memory 230. The processor 220′ may set at least one of an exercise course, the number of times of exercising, a weight, and a time of the exercise equipment to correspond to the recommended exercise program corresponding to the user. The processor 220′ may collect a user's motion information corresponding to the recommended exercise program.

FIG. 11 is a flowchart for receiving authentication information through human body communication in exercise equipment according to various example embodiments of the present disclosure. In the following description, operation 1001 in FIG. 10 of detecting body contact will be described.

Referring to FIG. 11, in operation 1101, the exercise equipment may determine whether a body of a user is in contact with the exercise equipment through at least a region (for example, a handle) of the exercise equipment that is formed of a conductive member for human body communication. For example, in the case of the treadmill 500 of FIG. 5A, the processor 220′ may determine whether the body 272 of the user is in contact with the treadmill 500 through the handles 504. For example, the processor 220 may determine whether the body 272 of the user is in contact with the treadmill 500 based on a current change (or a change in the resistance value) acquired through the conductive member(s) 506 of the handle(s) 504.

When the user's contact with the exercise equipment is detected, the exercise equipment may determine whether an authentication event is generated based on user's contact information in operation 1103. For example, the processor 220′ may determine whether an authentication event is generated based on at least one of the number of times the user contacts and a contact holding time that is acquired through the handles 504 of the treadmill 500 as shown in FIG. 5A.

When user's body contact is not generated or the generation of an authentication event is not detected, the exercise equipment may determine not to provide an exercise service corresponding to the user. In this case, the exercise equipment may be driven by a user's operation on a button, but may put a limit to providing an exercise service such as automatically setting a recommended exercise program corresponding to the user who is authenticated through human body communication and collecting exercise information.

When the generation of the authentication event is generated based on the user's contact information, the exercise equipment may transmit an authentication information request signal through the body of the user which is in contact with the exercise equipment in operation 1105. For example, when it is determined that the authentication event is generated based on the user's contact information acquired through the handles 504 of the treadmill 500, the processor 220′ may transmit the authentication information request signal through the body 272 of the user which is in contact with the handles 504.

FIG. 12 is a flowchart for detecting user's exercise information in exercise equipment according to various example embodiments of the present disclosure. In the following description, operation 1007 in FIG. 10 of detecting (collecting) user's motion information will be described.

Referring to FIG. 12, when the authentication of the user corresponding to the corresponding authentication information succeeds using the authentication information acquired through the body of the user which is in contact with the exercise equipment (for example, operation 1005 of FIG. 10), the exercise equipment may detect recommended exercise information corresponding to the user in operation 1201. For example, the processor 220 may receive recommended exercise program information corresponding to the user through the body 272 of the user which is in contact with the exercise equipment. For example, the processor 220′ may detect at least one of an exercise history and personal information corresponding to the user who is successfully authenticated from the memory of a management device in communication with the exercise equipment. The processor 220′ may determine a recommended exercise program corresponding to the user based on at least one of the exercise history and the personal information corresponding to the user. For example, the processor 220′ may control transmitting identification information of the user who is successfully authenticated to a management device connecting communication with the exercise equipment. The processor 220′ may receive the recommended exercise program information corresponding to the user who is successfully authenticated from the management device. For example, the recommended exercise program may include at least one of an exercise course, the number of times of exercising, a weight, and a time of the exercise equipment. The processor 220′ may also receive the recommended exercise program by a communication from electronic device 201 through the human body 272.

In operation 1203, the exercise equipment may set an exercise mode of the exercise equipment to correspond to the recommended exercise information. For example, in the case of the treadmill 500 of FIG. 5A, the processor 220′ may set an exercise course, an exercise speed, and an exercise time corresponding to the recommended exercise program information. For example, in the case of the bike 510 of FIG. 5B, the processor 220′ may set an exercise course and an exercise time corresponding to the recommended exercise program information. For example, in the case of the dumbbell 520 of FIG. 5C, the processor 220′ may set an exercise weight and the number of times of exercising corresponding to the recommended exercise program information. For example, in the case of the butterfly machine 550 of FIG. 5D, the processor 220′ may set an exercise weight and the number of times of exercising corresponding to the recommended exercise program information.

In operation 1205, the exercise equipment may collect user's exercise information corresponding to the recommended exercise information. For example, in the case of the treadmill 500 of FIG. 5A, the processor 220′ may drive the running conveyer belt (tread) to correspond to the exercise course and the exercise speed corresponding to the recommended exercise program. The processor 220′ may collect user's exercise information corresponding to the motion of the running conveyer belt.

FIG. 13 is a flowchart of an example for providing user's exercise information in exercise equipment according to various example embodiments of the present disclosure. In the following description, operation 1007 in FIG. 10 of detecting (collecting) user's motion information will be described.

Referring to FIG. 13, when the authentication of the user corresponding to the corresponding authentication information succeeds using the authentication information acquired through the body of the user which is in contact with the exercise equipment (for example, operation 1005 of FIG. 10), the exercise equipment may determine whether an exercise start event is detected in operation 1301. For example, when the authentication of the user who is in contact with the exercise equipment succeeds, the processor 220′ may determine that an exercise start event corresponding to the user is generated. For example, when the authentication of the user who is in contact with the exercise equipment succeeds, the processor 220′ may determine whether an exercise start event is generated based on body contact information of the user with the exercise equipment. For example, the body contact information may include at least one of the number of times the user contacts and a contact holding time that is detected during a reference time. For example, when the authentication of the user who is in contact with the exercise equipment succeeds, the processor 220′ may determine whether an input to an exercise button is detected. For example, when the input to the exercise button is detected, the processor 220 may determine that an exercise start event corresponding to the user is generated.

When the generation of the exercise start event corresponding to the successfully authenticated user is detected, the exercise equipment may detect a user's exercise information corresponding to a user's operation on the exercise equipment in operation 1303. For example, in the case of the bike 510 of FIG. 5B, the processor 220′ may collect user's exercise information corresponding to rotation information of the rotary plate 518 rotated by the pedals. For example, in the case of the dumbbell 520 of FIG. 5C, the processor 220′ may collect user's exercise information corresponding to motion information of the dumbbell 520.

In operation 1305, the exercise equipment may determine whether the user's contact with the exercise equipment is released. For example, in the case of the bike 510 of FIG. 5B, the processor 220′ may determine whether the user's contact with the handles 511 or 513 is released. For example, in the case of the dumbbell 520 of FIG. 5C, the processor 220′ may determine whether the user's contact with the handle 524 of the dumbbell 520 is released.

When the user's contact with the exercise equipment is maintained, the exercise equipment may determine whether a period for transmitting exercise information comes in operation 1307. For example, when the generation of the exercise start event is detected, the processor 220′ may activate a timer which is driven during the exercise information transmission period. The processor 220′ may determine whether the driving time of the corresponding timer expires. For example, when the driving time of the timer expires, the processor 220′ may determine that the exercise information transmission period comes. For example, the timer may be reset when the processor 220′ transmits exercise information through the body 272 of the user.

When the exercise information transmission period comes, the exercise equipment may transmit at least a portion of the user's exercise information collected at the exercise equipment through the body of the user which is in contact with the exercise equipment in operation 1309. For example, the processor 220′ may control transmitting user's exercise information which is collected after a previous exercise information transmission period to the electronic device 201 through human body communication. For example, the processor 220′ may control transmitting a user's exercise information which is collected from an exercise start point of time of the user to the electronic device 201 through human body communication. According to one example embodiment, the processor 220′ may extract at least a portion of the exercise information collected at the exercise equipment and transmit the extracted information to the electronic device 201 through the body 272 of the user. For example, at least a portion of the exercise information transmitted to the electronic device 201 through the body 272 of the user may include at least one of an exercise time, the number of times of exercising, a distance, and burned calories.

When the exercise information transmission period does not come or the exercise information is transmitted to the electronic device, the exercise equipment may continuously detect user's exercise information on the exercise equipment in operation 1303.

When the user's contact with the exercise equipment is released, the exercise equipment may transmit the user's exercise information to a management device in operation 1311. For example, when the user's body contact with the exercise equipment is released, the processor 220′ may determine that the use of the exercise equipment is finished or stopped. Accordingly, the processor 220 may control the communication interface 270′ to transmit the user's exercise information collected through the sensor 270 to the management device (for example, the electronic device 202). For example, the communication interface 270′ may transmit the user's exercise information to the management device through short range wireless communication. For example, the management device may include an exercise information management server or a user's portable terminal.

According to various example embodiments of the present disclosure, the exercise equipment may determine whether the use of the exercise equipment is finished or stopped based on a user's contact release time on the exercise equipment. For example, when user's contact is detected again before a reference time elapses from the time that the user's body contact with the exercise equipment is released, the processor 220′ may determine that the user's exercise is maintained. That is, when user's contact with the exercise equipment is not detected even after the reference time elapses, the processor 220′ may determine that the user's exercise is finished or stopped.

FIG. 14 is a flowchart of another example for providing user's exercise information in exercise equipment according to various example embodiments of the present disclosure. In the following description, operation 1007 in FIG. 10 of detecting (collecting) user's motion information will be described.

Referring to FIG. 14, when the authentication of the user succeeds through human body communication of the user who is in contact with the exercise equipment (for example, operation 1005 of FIG. 10), the exercise equipment may determine whether an exercise start event is detected in operation 1401. For example, when the authentication of the user contacting the exercise equipment succeeds, the processor 220′ may determine that an exercise start event corresponding to the user is generated. For example, the processor 220′ may determine whether the exercise start event is generated based on body contact information of the user with the exercise equipment or an input to an exercise button. For example, when the generation of the exercise start event is detected, the processor 220′ may control the communication interface 270′ to transmit exercise start information to the electronic device 201 through the body of the user.

When the generation of the exercise start event corresponding to the successfully authenticated user is detected, the exercise equipment may detect user's exercise information corresponding to a user's operation on the exercise equipment in operation 1403. For example, in the case of the butterfly machine 550 of FIG. 5D, the processor 220′ may collect user's exercise information corresponding to an exercise weight and rotation information of the rotary member 538 or 539.

In operation 1405, the exercise equipment may determine whether an exercise end event of the user on the exercise equipment is generated. For example, when an input to the exercise button of the exercise equipment is detected, the processor 220 may determine that the exercise end event is generated. Specifically, in the case of the treadmill 500 of FIG. 5A, when an input to the exercise button (for example, an end button) is detected while the treadmill 500 is being driven, the processor 220 may determine that the exercise end event is generated.

When the generation of the user's exercise end event on the exercise equipment is not detected, the exercise equipment may continuously collect a user's exercise information in operation 1403. For example, when the user's contact with the exercise equipment is maintained, the processor 220 may periodically transmit a user's exercise information to the electronic device 204 through the body 272 of the user.

When the generation of the exercise end event of the user on the exercise equipment is detected, the exercise equipment may determine whether the user's contact with the exercise equipment is released in operation 1407.

When the user's contact with the exercise equipment is maintained, the exercise equipment may transmit at least a portion of the user's exercise information collected at the exercise equipment to an electronic device through the body of the user which is in contact with the exercise equipment in operation 1409. For example, the processor 220 may extract at least a portion of the exercise information collected at the exercise equipment and transmit the extracted information to the electronic device 204 through the body 272 of the user.

When the user's contact with the exercise equipment is released or the exercise information is transmitted through human body communication, the exercise equipment may transmit the user's exercise information to a management device in operation 1411. For example, when it is recognized that the use of the exercise equipment is finished or stopped, the processor 220 may transmit the user's exercise information collected at the exercise equipment to the management device (for example, the electronic device 202). For example, the processor 220′ may control to transmit the user's exercise information to the management device through short range wireless communication of the communication interface 270′. According to one embodiment, the electronic device may transmit the exercise information through human body communication and transmit the exercise information using short range wireless communication at the same time.

FIGS. 15A and 15B are views showing screen configurations of exercise information according to various example embodiments of the present disclosure.

According to one example embodiment, an electronic device (for example, the electronic device 201 of FIG. 2A) may receive exercise information from exercise equipment (for example, the exercise equipment) through human body communication. In this case, the electronic device may display the exercise information provided through human body communication on a display 1500 of the electronic device as shown in FIG. 15A. For example, the exercise equipment may transmit at least a portion of the exercise information collected at the exercise equipment through human body communication. When the exercise is finished or the user leaves a region where the exercise equipment is arranged (for example, a gym), the electronic device 201 may display at 1502 type of an exercise that has been performed by the user through the exercise equipment for a predetermined time (for example, today), an exercise time, and consumed calories information. The electronic device 201 may receive additional exercise data from a management device through wireless communication, and may update the exercise information provided from the exercise equipment. For example, the electronic device 201 may determine whether the user leaves the region where the exercise equipment is arranged based on at least one of satellite information, tagging information, or user's schedule information.

According to one example embodiment, a management device (for example, the electronic device 202) may receive user's exercise information from exercise equipment (for example, the exercise equipment 204) through short range wireless communication. In this case, the management device may display the exercise information provided from the exercise equipment on a display of the management device as shown in FIG. 15B. Specifically, the management device 1510 may display a user's exercise history 1512, 1514, an amount of exercise 1516, a type of an exercise 1518, and exercise efficiency which are collected at the exercise equipment on at least a portion of the display.
