Abstract
A head mounted display device, an object tracking apparatus and a method for tracking object thereof are provided. The object tracking apparatus includes a lens, a light splitting device, a programmable light source and an image extractor. The lens generates and projects a detection light beam to an object. The programmable light source has a plurality of sub-light sources. The sub-light sources respectively project a plurality of light beams to a plurality of positions of the light splitting device. The programmable light source receives a driving signal, and adjusts a light-on status of each of the sub-light sources according to the driving signal. The image extractor extracts a detection image from the object. Wherein, the light splitting device receives at least one of the light beams and generates at least one reflection light beam to the lens, and the lens generates the detection light beam accordingly.
