The invention is directed to systems, methods and computer program products for gaze tracking. An exemplary method includes directing light into an eye using a projector; detecting, using an image-capturing module, a reflection from a surface associated with the eye; and determining a line of sight associated with the eye based on the detected reflection. In some embodiments, the light comprises infra-red light. In some embodiments, the projector comprises a laser. In some embodiments, the projector comprises a liquid crystal on silicon (LCoS) chip. In some embodiments, the surface associated with the reflection is at least one of the cornea, the iris, or the retina. |
