Three-dimensional computer input device.

摘要

The preferred embodiment of this computer input device comprises a triplet of acceleration detectors (1...3) associated, respectively, with the three mutually orthogonal axes (X, Y, Z) of a coordinate system for determining the position in space of the input device, and a triplet of gyroscopes (4...6) respectively associated with the three rotational axes (Pitch, Roll, Yaw) of the input device for determining the absolute orientation of the input device. Electronic circuitry (7...18) is provided to convert the analog output signals of the motion sensing devices to digital input data to enable the associated computer to compute the data relative to position and orientation of the input device for possible three-dimensional interactive graphics and imaging on a computer display unit.
