Abstract
A three-dimensional (3D) maneuvering device generates 3D data by irradiating a two-dimensional (2D) reference surface with light of variable frequency. The 3D maneuvering device has high sensitivity, high resolution, and immunity from the noise caused by human vibrations. A rotational motion vector is derived by comparing the relative motion vectors derived from a pattern recognition process of surface features on the same reference plane with the positional data derived using the color index data. Thus, a single gestural movement of the operator's hand provides both the translational and rotational motion data simultaneously.
