ELECTRIC FIELD COMMUNICATION SYSTEM, COMMUNICATION METHOD IN ELECTRIC FIELD COMMUNICATION SYSTEM, AND RECEIVER UNIT OF ELECTRIC FIELD COMMUNICATION SYSTEM

摘要

To provide an electric field communication system capable of detecting the operation of an object with a simple configuration, and to provide a communication method in the electric field communication system, and a receiver unit in the electric field communication system.SOLUTION: In a human body communication system comprising a transmitter 10 for transmitting signals, and a receiver unit 20 for receiving signals from the transmitter 10 by human body communication through an electric field intervening in the human body, the transmitter 10 has a signal transmission section 11 for transmitting signals by an electric field generated by inducing an electric field on the surface of the human body, the receiver unit 20 has a signal reception section 21 for receiving signals transmitted by the signal transmission section 11 by the electric field intervening in the surface of the human body, and a reception state determination part 24 for determining the reception state of signals received by the signal reception section 21. In addition to determination whether or not reception of signal is possible, the reception state determination part 24 determines reception state capable of signal reception in several stages, or in stepless.SELECTED DRAWING: Figure 2
