Abstract: A tracking device including an image sensor, a light source and a processor is provided. The image sensor senses reflected light or scattered light formed by the light source illuminating a work surface. The processor calculates a trace of the tracking device according to one of the reflected light and the scattered light that generates more apparent image features so as to increase the adaptable work surfaces.

Abstract: An optical assembly includes a light source and a beam splitter. The light source is used for emitting an incident beam. The beam splitter is used for dividing the incident beam into a plurality of outgoing beams. The incident beam and the outgoing beam are both invisible light. The outgoing beams enter an eyeball and form a plurality of glints on the eyeball. The glints are formed on the region outside the pupil.

Abstract: An eye tracking apparatus and an image capture module thereof for capturing an iris image are provided. The image capture module includes a carrier, a light source and an image sensing unit. The light source and the image sensing unit are both disposed on the carrier and fastened ahead of the eye by carrier. The light source emits a light beam to the eye, and the image sensing unit receives the light beam reflected from the eye to capture the iris image. The light source and the image sensing unit are arranged at two different sides of a longitudinal reference plane.
