Abstract: A frameless optical touch device includes an indication plane, an image sensing unit, a light emitting unit and a processing unit. There is no any frame disposed on a periphery of the indication plane such that a first light from an external environment can enter a sensing region defined on the indication plane through the periphery of the indication plane.

When there is no any touch object in the sensing region, the image sensing unit senses the first and second lights to generate a first image. When a touch object is in the sensing region, the image sensing unit senses the first and second lights to generate a second image. The processing unit compares brightness of the first image with brightness of the second image so as to obtain a position blocked by the touch object.
