## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the priority of Korean Patent Application Nos. 10-2009-0129266 filed on Dec. 22, 2009 and 10-2010-0044418 filed on May 12, 2010, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the control of an electronic apparatus, and more particularly, to an electronic apparatus having a control function using human body communication and a portable terminal having an electronic apparatus control function using human body communication, whereby electronic apparatuses can be conveniently controlled through human body communication.
2. Description of the Related Art
Generally, the operations and functions of electronic apparatuses, such as television sets, audio/video systems, air conditioners, and so on, are controlled using buttons provided on external housings thereof or remote controllers separately provided. However, as the number of electronic apparatuses increases, the number of different remote controllers also increases and thus it is difficult to manage and store them.
Learning remote controllers capable of solving the above-described inconvenience have been commercially available. However, their initial setting is complicated because a user must teach the learning remote controllers functions corresponding to buttons of remote controllers. Also, when a battery thereof is discharged, the taught data is reset, and thus, the user must again teach the learning remote controllers.
Furthermore, portable terminals (e.g., mobile phones) with a built-in remote control function have recently been manufactured. To this end, portable terminal manufacturers must embed remote control functions in advance according to electronic apparatus manufactures and models. Therefore, such portable terminals cannot be used in electronic apparatuses whose remote control functions are not embedded. Even in the case that the remote control function is embedded, the use of the portable terminals may be inconvenient when the keys of the portable terminal and the keys of the remote controller do not exactly coincide with one another.

FIGS. 1 through 3 are conceptual diagrams explaining an electronic apparatus having a control function using human body communication according to an embodiment of the present invention, and an operation of a portable terminal having an electronic apparatus control function using human body communication.
Referring to FIG. 1, various electronic apparatuses 100, such as a refrigerator, a television set, and an audio system, have human body communication functions and include electrodes 101 installed in external housings, wherein the electrodes 101 can come into contact with the user's body 10. Also, the electronic apparatuses 100 store control data in nonvolatile memories provided therein, and provide the control data to a portable terminal 200 contacted with the user's body 10 through human body communication. The control data may refer to a software program which can control the electronic apparatuses 100.
For example, when the user touches the electrode 101 of the electronic apparatus 100 in such a state that the user is in contact with the portable terminal 200, the electronic apparatus 100 reads the stored control data, converts the read control data into signals which can be transmitted through human body communication, and provides the converted signals to the electrode 101. The control data provided to the electrode 101 is downloaded into the portable terminal 200 through the user's body 10. The portable terminal 200 also has a human body communication function and an electrode (not shown) which can come into contact with the user's body 10 in order for human body communication to occur.
The portable terminal 200 which has downloaded the control data of the electronic apparatuses 100 using human body communication processes the control data and displays an electronic apparatus control menu on a display unit of the portable terminal 200. When the control data regarding the plurality of electronic apparatuses 100 is stored in the portable terminal 200, the portable terminal 200 may display an electronic apparatus selection menu to allow the user to select a specific electronic apparatus, and then display the control menu for controlling the electronic apparatus which is selected by the user.
As illustrated in FIG. 1, the portable terminal 200 may download the control data from the electronic apparatuses 100 through human body communication and control the electronic apparatuses 100 by using the downloaded control data.
The portable terminal 200 may control the electronic apparatuses 100 by using human body communication or may control the electronic apparatuses 100 by using wireless communication.
The operation of controlling the electronic apparatuses using human body communication will be described below with reference to FIG. 2. When the user selects a predetermined control menu for a predetermined electronic apparatus (e.g., a television set), which is displayed on the portable terminal 200, and contacts the electrode 101 of the electronic apparatus 100 to be controlled, in such a state that the user comes into contact with the portable terminal 200, the portable terminal 200 converts the control data corresponding to the control item selected by the user in accordance with a human body communication standard (or protocol) in order to enable human body communication. Then, the portable terminal 200 transmits the converted control data to the electrode 101 of the electronic apparatus 100 through the user's body 10, and performs the operation or function corresponding to the control signals received through the electrode 101 thereof.
As illustrated in FIG. 3, the portable terminal 200 may control the electronic apparatuses through wireless communication. Referring to FIG. 3, the portable terminal 200 may control the electronic apparatuses by downloading the control data from the electronic apparatuses through human body communication, converting the control data selected by the user through a wireless control module (e.g., an infrared transmission module or an RF transmission module) in accordance with a wireless transmission protocol, and transmitting the converted control data to the corresponding electronic apparatuses.
FIG. 4 is a block diagram illustrating the configuration of the electronic apparatus having the control function using human body communication according to the embodiment of the present invention. Well-known structures will not be described in detail to avoid an ambiguous interpretation of the present invention.
Referring to FIG. 4, the electronic apparatus 100 having the control function using human body communication may include a first control unit 110, a first storage unit 120, a first human body communication unit 130, an electrode 140, and a control signal reception unit 150.
When the first control unit 110 determines that the user's body comes into contact with the electrode 140, it reads the control data stored in the first storage unit 120, provides the read control data to the first human body communication unit 130, and performs a control to allow the control data to be transmitted to the user's body through the electrode 140.
Also, the first control unit 110 receives a control signal from the first human body communication unit 130 or the control signal reception unit 150 and generates apparatus control signals which control the function or operation of the electronic apparatus according to the received control signals.
The first storage unit 120 stores the control data. The control data may be a software program designed to control the electronic apparatus.
The first human body communication unit 130 converts the control data provided from the first control unit 110 into signals, which can be transmitted through human body communication, in accordance with the human body communication standard (or protocol), and then transmits the converted signals through the electrode 140 to the user's body which is in contact with the electrode 140.
Also, the first human body communication unit 130 receives the control signals provided from the user's body through the electrode 140, processes the received control signals, and provides the processed control signals to the first control unit 110. The control signals represent signals which control the function or operation of the electronic apparatus.
The electrode 140 may be installed in the external housing of the electronic apparatus which can be easily contacted with the user's body. The electrode 140 transmits the signals provided from the first human body communication unit 130 to the user's body contacted with the electronic apparatus, or provides the signals from the user's body to the first human body communication unit 130.
