Abstract

Described is a system and method for actuating an infrared touch panel. The mobile device may include an infrared touch panel and a housing having a window opening which provides an access to at least a portion of a surface of the touch panel. The system may also include a plurality of light sources disposed along a perimeter of the touch panel so that light beams emitted by the light sources traverse the surface of the touch panel and at least one sensor that detects first data. The first data includes spatial orientation data and motion data of at least one of the touch panel and the device. In addition, the system may also include a processor which compares the first data to second data to determine an occurrence of an event related to at least one of the touch panel and the device. The second data includes predetermined threshold ranges of changes in the spatial orientation data and the motion data. If the event occurrence is detected, the processor selects a predetermined procedure to control at least one of the light sources and the touch panel as a function of one of (i) the first data or (ii) the first data and the second data, and executes the selected procedure.
