External device for mobile communication terminal mobile communication terminal and external display system for mobile communication terminal

摘要

The present invention provides an external apparatus for mobile communication terminal, a mobile communication terminal, and an external display systems for mobile communication terminal by which application programs using detection means can be executed in a main body of a mobile communication terminal without raising the cost of the main body. The external apparatus 30 for mobile communication terminal is comprised of a sensor detection unit (detection means) 312 and a communication control unit (data transmission means) 311. The sensor detection unit 312 detects at least one of position, direction, attitude and movement of the external apparatus 30 for mobile communication terminal. The communication control unit 311 sends detection result data acquired based on detection results by the sensor detection unit 312 to the mobile communication terminal by wired or wireless non-public short-range communication.
