EXTERNAL DEVICE FOR MOBILE COMMUNICATION TERMINAL, MOBILE COMMUNICATION TERMINAL, AND EXTERNAL DISPLAY SYSTEM FOR MOBILE COMMUNICATION TERMINAL

摘要

An external device for a mobile communication terminal, a mobile communication terminal, and an external display system for a mobile communication terminal, wherein an application program using determination means can be executed within the mobile communication terminal without increasing the costs of the mobile communication terminal. An external device (30) for a mobile communication terminal includes a sensor part (determination means) (312) and a communication control part (data transmitting means) (311). The sensor part (312) determines at least one of the position, orientation, attitude and movement of the external device (30). The communication control part (311) transmits determination data obtained by the sensor part (312) to the mobile communication terminal via a short distance wire or a radio non-public communication.
