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.

13. A user instruction input device comprising:
-
an angular rate sensor adapted to sense an angular rate at which the device rotates to provide a first output; an acceleration sensor adapted to sense an acceleration of the device to provide a second output; and a processing unit adapted to convert the first output of the angular rate sensor into a first rotation angle, convert the second output of the acceleration sensor into a second rotation angle, and compute a weighted average of the first rotation angle and the second rotation angle based on the first output and/or the second output to produce an attitude angle estimate. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
