<p>PURPOSE:To make the movement of the position of the indication input device appear faithfully as the movement of a cursor on the screen of a terminal device. CONSTITUTION:An initial position and an attitude are inputted from the position detection unit 1 of the mouse type indication input device. Angular velocity detection units 5, 6, and 7 detect the angular velocities of the mouse type indication input device which beams to move around directions x', y' and z'. The detection results are integrated to find a movement angle, which is further added to the previously inputted initial attribute to calculate a current attribute. Acceleration detection units 2, 3, and 4 detect acceleration. On the basis of attribute parameters showing said found attribute, the acceleration of a system L is calculated. On the basis of the acceleration, integral calculation is performed to calculate a relative speed and integral calculation is further performed to calculate displacement; and the initial position is added to the obtained displacement to find the relative position of a system L'.</p> |
