External operation signal recognition system of a mobile communication terminal

摘要

Provided is an external operation signal recognition system of a mobile communication terminal which includes an external operation signal generation apparatus separate from the mobile communication terminal for generating synch and operation signals; and an external operation signal recognition apparatus for receiving the synch signal, sensing the external operation signal through at least three operation signal sensing units, generating three dimensional (3D) coordinates corresponding to a position of the external operation signal generation apparatus using the received synch signal and the sensed external operation signal, and realizing the external operation signal using the generated 3D coordinates. Accordingly, a user can easily operate a 3D application without directly moving the mobile communication terminal.
