Gesture recognition system and method for gesture recognition

The present invention provides a gesture recognition system, a gesture recognition system comprises at least one light emitting module, the at least one angle detecting module, an image capturing module with the gesture information control module. The light emitting module to emit light. Detecting the reflected light receiving angle of the light module light and the reflected light output sensing signal. At least one two-dimensional image with reference image capture module for capturing a user's hand, wherein a distance between the detection module and the angle of the image capturing module is a fixed length. Gesture information control module respectively according to the light sensing signal and the reference image to obtain a plurality of two-dimensional angular reference data, the reference data and further calculates the hand depth data according to a plurality of fixed length angles, thereby to identify the user's hand movements.
