A communication unit prevents a malfunction which initiates communication against a user's will when communication for the purpose of remote dialog, without requiring a complex operation on the part of the user. This communication unit, used when a sender transmits his or her image or speech information to a recipient, comprises: a device that acquires image and speech information; a home server that transmits communication data indicating the information acquired by the information acquisition device to a device possessed by the recipient; and a detection unit that detects an object to be detected which is generated or changed by an action of the sender. The detection unit detects mutually different types of the objects each to be detected. Then, the home server starts transmitting the communication data when each detection result from each of two or more types of the detection units satisfies a predetermined condition.

Communication unit

A system and method are provided to hold a dialog between communicators while the communicators are viewing their images each other and which prevents the presence of an image display screen from being noticeable in a non-communication state. A first unit for the communicator generates and transmits first data indicating the image of the communicator. A second unit for the communication partner expands the first data received via a communication line to display the image of the communicator on the display screen, and generates and transmits second data indicating the image of the communication partner in front of the display screen. A human sensor is configured to detect that the communication partner is at a predetermined position in a home. Only during the period of the human sensor detecting that the communication partner is at the predetermined position, the display-cum-mirror forms a display screen, and otherwise, a mirror.
