PURPOSE: A mouse including 3 degrees of freedom including rotation is provided to enhance the directivity toward a rotation direction by using mouse-rotation information as an input signal. CONSTITUTION: Optical sensors for measuring the variation in the X-axis or Y-axis are arranged at a certain interval to measure the movement degree and the rotation degree of the X and Y-axes of a mouse. The arrangement of the optical sensor is arranged horizontally, vertically or diagonally to have certain distance. The position of a first sensor(1) for determining the movement degree in the X and Y-axis direction is adjacent to the central point when rotating a mouse after gripping the mouse. |
