Japanese Patent JP4257611
Kind Code:
B2
Abstract:
The present invention relates to a device and a method for communication, and a program that make it possible to provide a communication environment not limited by a use environment. An electrode controlling unit in a transmitting device checks a state of capacitive coupling of each of an electrode and an electrode in an electrode unit with surroundings, controls connection of each electrode to a transmitting unit according to a result of the check, and makes the electrode and the electrode function as a transmission signal electrode or a transmission reference electrode, the transmission signal electrode and the transmission reference electrode being different from each other. The transmitting unit connects the electrode and the electrode to an amplifying unit under control of the electrode controlling unit, and transmits a signal to a communication medium via one of the electrodes. The present invention is applicable to communication systems.
