ABSTRACT:
A three-dimensional optical mouse device with a Micromirror Array Lens (MMAL) is provided. To have the three-dimensional optical mouse system, a three-dimensional imaging device is used for detecting the motion of optical pointer or fingers of the user and gives a location of the pointer to computer working as a pointing device in three-dimension. This three-dimensional pointing system uses three-dimensional imaging device using MMAL with variable focal length.
