<p>PROBLEM TO BE SOLVED: To provide an input device where the operability of a user is improved and angle information can be detected. SOLUTION: The moving amount of two balls 1a and 1b is detected and a moving amount/rotary angle calculation part 6 calculates not only the moving amount of the two-dimensional direction of a mouse 10 but also information on the rotary angle of the mouse 10 based on the moving amount. A weighting part 8 weights the calculated rotary angle by weight which is set by a volume 7. A straight line and the angle of a graphic, which are displayed on the display part of a computer 20, are changed by the weighted rotary angle (Θ).</p> |
