Patent ID: 8421748

Claim:
An information exchange device comprising: a human body communication unit which applies information flowing via a first human body to a second human body and detects information flowing via the first human body; an information transmission unit which transmits information via the human body communication unit; an identification unit which identifies another device which can transmit information from the information transmission unit; a detection unit which detects a contact state with the first and second human bodies; and a transmission control unit which starts transmission of information according to identification by the identification unit and a detection by the detection unit, wherein the identification unit includes an enrollment unit which enrolls another device for information transmission by the information transmission unit, and a sensing unit which senses another device, and identifies that the other device sensed by the sensing unit is capable of information exchange by the transmission unit if the other device matches the enrollment of the enrollment unit, and wherein the transmission control unit does not start the information transmission to the other device even if the other device is enrolled in the enrollment unit, if a term during which the sensing unit has not sensed the enrolled device continues over a predetermined time and even if a next contact state with another human body is detected with respect to the enrolled device.
