Abstract

An information processing apparatus (1) has a coordinate data inputting means (31, 32) for sequentially inputting coordinate data by operation of a movable member (6), the coordinate data corresponding to the position of the movable member (6). The movable member is a pen (6), a change of the moving angle of its locus being detected by a detecting means (24) as an angle between the position of the pen (6) and a predetermined base position based on the coordinate data. The base position is displayed on a display (5) as a circular image in the form of a dial on which the pen (6) may be penned down so that a processing means detects the rotating angle of the pen (6) to change a function to be processed. In one arrangement, the circular image acts as a jog control, rotation of the pen (6) causing turning of page numbers.
