A touch module including an image sensing unit, a plurality of first reflecting elements, a plurality of second reflecting elements, and a processing unit is provided. The image sensing unit is positioned in correspondence with a first corner of a sensing area and capable of capturing a sensing image to output an image signal. The first reflecting elements and the second reflecting elements respectively have different first angles and different second angles, are disposed along a first and the second edges of the sensing area respectively, and are capable of reflecting a touch object to form a first and a second image in the sensing image. A second corner formed by the first the second edges is diagonal to the first corner. The processing unit is coupled the image sensing unit and receives the image signal to determine the position of the touch object relative to the sensing area.
A touch module comprising:
