<p>The present invention makes it possible to enhance the degree of freedom in communication using a quasi-electrostatic field. According to the present invention, by causing a human body to act as an antenna to send and receive ID information D5 while avoiding 8 Hz peaks Px that appear with a high strength, in a walking quasi-electrostatic field HSE formed in the neighborhood of the human body in response to a walking motion of the human body, the ID information D5 can be sent and received via a quasi-electrostatic field DSE formed isotropically around the human body with the human body as an antenna while destruction of the information by the 8 Hz peaks PX is prevented. Thus the degree of freedom in communication using a quasi-electrostatic field can be enhanced. <IMAGE></p> |
