Abstract
Systems and methods for implementing touchscreen displays that utilize a transmitter system to dynamically scan at least one light beam across a surface of interest such that substantially every point in a region above the surface of interest is dynamically scanned by a light beam from two directions, a receiver system to receive and detect the at least one dynamically scanned light beams, and a processor configured to determine locations of contact are provided. The systems and methods may utilize a transmitter system that includes dynamic transmitters, which may be in the form MEMS micromirrors used in conjunction with infrared semiconductor lasers.
