Abstract
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.
