摘要: An optical touch apparatus and a touch method thereof are provided. A plurality of light sensing units are disposed between a first scanning light source and a second scanning light source, wherein the light sensing units, the first scanning light source and the second scanning light source are disposed at a same side of a touch surface. A touch position of an input tool is determined according to an intensity of a scattered light generated by an input tool and sensed by the light sensing units and generated when a first scanning beam and a second scanning beam scan the input tool.
