Abstract
A vehicular optical touch apparatus includes a screen, an elastic layer, a detection light source, and an image detector. The elastic layer is disposed on the screen and includes a first surface facing away from the screen and a second surface facing the screen. The second surface includes a plurality of inclined surfaces inclined with respect to the first surface. The inclined surfaces totally reflect at least one portion of ambient light entering the elastic layer through the first surface, so that the portion of ambient light leaves the elastic layer through the first surface. The detection light source emits detection light toward the elastic layer. When an object presses the first surface to deform the second surface, the detection light sequentially passes through the elastic layer, is reflected by the object, passes through the elastic layer again, and is transmitted to the image detector.
