Abstract
A pointing device includes an operation body that operates a cursor moving on a display screen, a detection unit that detects an operating force applied to the operation body, a cursor control unit that generates cursor movement data according to the operating force, a communication control unit that outputs the cursor movement data to the outside, and a central control unit that controls the operation of the units. The cursor control unit includes a cursor-speed determining unit and a recording unit. The cursor-speed determining unit determines cursor moving speed in an X-Y plane direction by a predetermined reference function from an operating force in an X-Y plane direction and an operating force in a perpendicular z axis direction perpendicular to the X-Y plane direction that are detected by the detection unit. The recording unit stores the reference function. The cursor-speed determining unit changes the reference function in accordance with the magnitude of the operating force in the perpendicular Z axis direction, and determines the cursor moving speed in the X-Y plane direction by the changed function.
