Abstract: An interpersonal communication system (1) includes a portable personal item (2) (such as an item of clothing, a clothing accessory or a portable device) fitted with a recognition device (3); a server (4); and network communication means (5). The recognition device (3) has a sensor (6) for detecting a physical, physiological or body parameter (e.g. heartbeat) of the person wearing the item (2); a microcontroller (7) connected to the sensor (6) and containing a unique code; and a wireless communication device (8) for transmitting to the server (4), upon the sensor (6) detecting a variation in the parameter, an identification signal identifying the unique code. Upon the server (4) receiving the signal, the network communication means (5) send a message to one or more users selected by the server (4).

Abstract: A personal item (3), such as an item of clothing, an accessory or a portable device, is fitted with an identification tag (2) having memory means (11) for recording an individual code assigned to the tag (2), and emitting means (12) for emitting a signal representing the individual code; a portable detecting device (4) has enabling means (16) for enabling the emitting means (12) and for transmitting an inquiry signal to the tag (2) and receiving, in response, the signal representing the individual code and emitted by the emitting means (12) of the tag (2); and the individual code so detected may then be used as an E-mail box address on a dedicated internet web site to contact the owner of the tag (2), thus providing a straightforward, effective way of establishing interpersonal relationships between strangers, while at the same time ensuring their anonymity.
