Abstract
A touch and gesture control system including a light curtain module, an invisible light lighting module, an image capturing module and a control unit is provided. The light curtain module is configured to form a touch zone. The invisible light lighting module is configured to form a gesture control zone. The touch zone and the gesture control zone are at least partially overlapped. The control unit is electrically connected to the light curtain module, the image capturing module and the invisible light lighting module. The control unit turns on the light curtain module and controls the image capturing module to capture a first set of images when executing a touch mode, and turns on the invisible light lighting module and controls the image capturing module to capture a second set of images when executing a gesture control mode. A touch and gesture control method is also provided.
