<p>PURPOSE: To accurately indicate a position regardless of the motion of a moving body. CONSTITUTION: Motion detection sensors 11 and 12 detect the rotational angular speeds of a mouse 10 in the up-down direction and right-left direction and their signals are inputted to a movement quantity arithmetic part 25 through a modulation part 15, a transmission part 16, a reception part 21, a demodulation part 22, and a signal discrimination part 23. The movement quantity arithmetic part 25 calculates the up-down movement quantity and the right-left movement quantity of the hand of an operator on the basis of the signals of the motion measurement sensors 11 and 12 and calculates the right-left movement quantity of an automobile on the basis of the output signal of a motion measurement sensor 24, and further calculates the difference between the right-left movement quantity of the hand of the operator and the right-left movement quantity of the automobile to find the right-left movement quantity of the mouse 10 that the operator really operates. A control part 26 moves a cursor on a display 27 by a distance corresponding to the movement quantity of the hand of the operator.</p> |
