Abstract
A wearable touch device comprising a carrier, a pattern emitting unit, an image acquisition unit, an image monitoring unit and a processing unit, the carrier is wearable, the pattern emitting unit emits a scanning pattern to a touch surface capable of being touched by a touch end, the image acquisition unit is used for acquiring an image formed by projecting the scanning pattern on the touch surface and sending image information of the acquired image to the processing unit, the image monitoring unit is used for monitoring current light energy of the scanning pattern in regions of the touch surface and sending current light energy information to the processing unit, and the processing unit is used for processing the image information of the acquired image and the current light energy information to determine a touch position of the touch end on the touch surface and generate corresponding command information.
