The first light source emits first light beam which travels within the light guide device and is reflective by an object close to or in contact with a surface of the light guide device to become a first image light beam. The first image light beam is reflected by a light reflecting device. The image sensing module receives the first image light beam. The second light source emits a second light beam, wherein when the optical touch apparatus moves on a working surface, the second light beam is reflective by the working surface to form a second image light beam which is received by the same image sensing module. | 11-05-2015 |
20160072984 | GESTURE RECOGNITION APPARATUS AND COMPLEX OPTICAL APPARATUS - The present invention discloses a gesture recognition apparatus including a substrate, a light emitting device, an image sensor and a processing unit. The light emitting device is for emitting a light beam according to a first clock signal. The image sensor is disposed on the substrate and is for receiving the light beam reflected by an object according to a second clock signal to generate an object image. The processing unit is disposed on the substrate and is for recognizing the object image detected by the image sensor to provide a command signal. There is a correlation between a period of the first clock signal and a period of the second clock signal. The present invention also provides a complex optical apparatus. | 03-10-2016 |
