GESTURE RECOGNITION MODULE AND GESTURE RECOGNITION USING THE MODULE

摘要

The present invention relates to a gesture recognition module which effectively releases the heat generated by a laser diode and is thin enough to be embedded in a laptop or a TV, and a gesture recognition system using the module. The gesture recognition module comprises a laser, a diffuser, and a PCB. The laser emits light with a certain wavelength to a subject. The diffuser is installed on the top of the laser and diffuses the light emitted by the laser at a given angle. On the top of the PCB, the laser and the diffuser are installed, and a flexible cable which is electrically connected to a control device controlling the laser is installed to the PCB. At least one from a metal plate or plastic tape is attached to the bottom of the PCB.
