摘要： A touch panel capable of recognizing at least one gesture and the method thereof are provided. The touch panel comprises: a first optical unit, comprising a first light emitting element and a first light receiving element, arranged at a first position of the touch panel; a first optical element arranged along a first edge of the touch panel for reflecting light; a second and a third optical element arranged along a second and a third edge of the touch panel, respectively, for retro-reflecting the light, the second edge being adjacent to both the third edge and the first edge; and a processing unit for recognizing the at least one gesture according to changes to distance and slope of possible touch points.
