Problems solved by technology

[0007] In application examples such as user authentication, the size of communication data is small and processing is completed in a short time, so that communication stability is not such a big problem
On the other hand, in application examples where large volumes of data such as music data and moving image data are transmitted within a certain period of time, communication stability is an important issue

Embodiment Construction

[0031] Now, embodiments of the present technology will be described in detail with reference to the accompanying drawings.

[0032] figure 1 A usage form of the human body communication system 10 according to an embodiment of the present technology is schematically shown. figure 1 The illustrated human body communication system 10 includes a human body side communication device 11 composed of a portable terminal such as a PDA and a device side communication device 12 including a touch panel.

[0033] The human body communication system 10 according to this embodiment is an electric field type human body communication system using the property of the human body as an insulator. When using the electromagnetic field, the user does not have to touch the portable terminal serving as the body-side communication device 11, so it is sufficient for the user to put the portable terminal in his / her pocket and carry it.

[0034] The device side communication device 12 includes a touch p...

Abstract

A communication device includes an electrode, a communication unit configured to process a communication signal that is transmitted from / received by the electrode, and a control unit configured to control a communication operation in the electrode and the communication unit depending on a communication state.

Description

technical field [0001] The present technology relates to a communication device and a communication system that perform data communication by using a human body as a medium. Specifically, the present technology relates to a communication device and a communication system that perform human body communication of an electric field communication system by mainly using the characteristics of a human body as an insulator. Background technique [0002] Two or more information devices can communicate with each other through various media such as wired or wireless. Human body communication technology in which a human body is introduced into a transmission channel has recently started to attract much attention. Human body communication does not use a communication cable, thereby facilitating, for example, music data transmission between a portable music reproduction device and a head phone. Also, in human body communication, communication signals pass through the user's body, so in...
