Abstract
A touch control apparatus includes a first light source, a first sensor, a second light source, a second sensor and a controller. An associated selection method includes following steps. The first and the second light sources are driven to respectively generate a first and a second plane lights. Both the first and the second plane light are reflected by at least two touch points. A left reflected light distribution is sensed and transformed into multiple left depth parameters by the first sensor, and a right reflected light distribution is sensed and transformed into multiple right depth parameters by the second sensor. Correspondingly, positions of the at least two touch points are selected from the candidate touch points according to the left and right depth parameters.
