Abstract
Acceleration data which is output from an acceleration sensor is obtained. A rotation motion of an input device around a predetermined direction as a rotation axis is determined by comparing a start point in a two-dimensional coordinate system which is represented by the first acceleration data obtained in a predetermined period, and an end point in the two-dimensional coordinate system which is represented by the last acceleration data obtained in the predetermined period. Coordinate axes of the two-dimensional coordinate system are defined based on components of the two axial directions of the acceleration data, and an origin of the two-dimensional coordinate system represents a value of the acceleration data in the state where no acceleration including the acceleration of gravity acts upon the acceleration sensor. Motion data including at least the determined rotation motion is output.

27. A controller comprising:
-
an acceleration sensor; an imaging element for obtaining an image of infrared light; a plurality of operation buttons; a processor, operatively coupled to the acceleration sensor, the imaging element and the operation buttons, for receiving input signals resulting from operation of one or more of the acceleration sensor, the imaging element and the operation buttons, and for generating an output signal; a module for receiving the generated output signal from the processor and for transmitting a signal wirelessly from the controller; an elongated housing, having a shape that extends in a longitudinal direction from a front surface to a rear surface of the housing, the housing enclosing at least the acceleration sensor, the imaging element, the processor, and at least a portion of the transmission module and having a hole defined in its front surface to allow infrared light to pass therethrough; and a connector for engaging to a device external to the controller through a hole defined in the rear surface of the housing. - View Dependent Claims (28, 29, 30, 31, 32, 33)
