Abstract
Provided is a user instruction input device operating in a three-dimensional space. The user instruction input device includes a first sensor that senses the angular rate of the device centering on at least one axis, a second sensor that senses the acceleration of the device at least for one direction, and a processing unit that calculates a first rotation angle in a coordinate system independent of the attitude of the first device from the output value of the first sensor, calculates a second rotation angle in the coordinate system from the output value of the second sensor, and calculates the final attitude angle by combining the first rotation angle and the second rotation angle.
