<p>PROBLEM TO BE SOLVED: To provide a portable information processor which secures efficient input processing or selection processing regardless of the miniaturization of the portable information processor, does not limit a use place and does not impose a burden on a user at a low cost. SOLUTION: This portable information processor 101 which selects various processing with a pointer on the display screen 102 and shows execution results of the various selected processing on the display screen is provided with an acceleration detecting part 201 which detects acceleration added to a device main body, a position calculating part 202 which calculates the pointer position based on the acceleration detected by the part 201, displaying means (display controlling part 203 and a display screen unshown in figure) which show the pointer at a position calculated by the part 202, a selection deciding part 204 which selects various processing corresponding to the pointer position displayed by the displaying means and decides the execution of the corresponding processing and an application executing part 205 which controls each part and also performs execution control of various processing.</p> |
