The present invention relates to an apparatus for providing an azimuth angle, i.e., an apparatus for calculating an azimuth angle using an angular rate sensed by a gyro sensor, which has rotated by an arbitrary angle, and an angle of rotation. The apparatus for providing an azimuth angle in accordance with one embodiment of the present invention may comprise a rotating member, an angular rate sensor mounted on the rotating member, and a driving unit configured to rotate the rotating member by a first angle. The angular rate sensor may be configured to sense an angular rate of the rotating member. The apparatus may further comprise an azimuth angle estimation unit configured to estimate an azimuth angle of the apparatus based on the sensed angular rate and the first angle.

Apparatus for providing an azimuth angle

Provided is an input device for operating in a three-dimensional space and inputting user instructions. The input device includes a first operation unit that calculates a first rotation angle in a coordinate system independent of the attitude of the device based on the output value of a first sensor, a second operation unit that calculates a second rotation angle in the coordinate system based on the output value of a second sensor, an attitude angle measuring unit that calculates the attitude angle of the input device by combining the first rotation angle and the second rotation angle, and an intensity calculation unit that calculates force intensity in the coordinate system using acceleration of the input device and the attitude angle of the input device obtained in the attitude measuring unit.
