Digitally Transparent Interface Using Eye Tracking

See-through displays allows user to view the scene behind the display. See-through displays are playing a crucial role in shaping augmented reality applications. However, the cost of the transparent displays are higher than the normal displays. In this paper, we disclose a low cost digitally transparent display using a depth camera, two color cameras and a regular display. The method described in this paper tracks the eyes of the user and finds the corresponding distance from the depth sensor and renders the rear camera preview of the tablet or mobile in such a way that the user perceives it as a transparent display. This method has the potential to change the augmented reality applications in tablets or mobiles from a video see-through experience to a glass see-through experience.
