PORTABLE TERMINAL DEVICE, MOUSE APPLICATION PROGRAM, AND METHOD OF USING PORTABLE TERMINAL DEVICE AS WIRELESS MOUSE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a wireless mouse function in a portable telephone.

SOLUTION: Based on the amount of displacement between front and rear frames in an image captured by a camera, motion vector information is calculated which corresponds to the movement direction and distance of a case in the portable telephone 40. The short-distance wireless transmission of the motion vector information is performed to a short-distance wireless communication unit 42 at the side of a personal computer device 41 via a short-distance wireless communication unit. The control unit of the personal computer device performs the motion display control of a pointer P displayed on a monitor device 44 based on the motion vector information received from the portable telephone, thus enabling the pointer P displayed on the monitor device 44 to be moved by using the portable telephone as the wireless mouse device.
