Eye-tracking system for reverse glasses

Abstract

Reverse glasses can flip the vertical view or horizontal view, i.e., we see a mirrored image. Reverse glasses are composed of triangular prisms which locate the field image by total reflection. In recent years, in the field of psychology and brain science, reverse glasses are used to investigate adaptability of the brain. However, the information of eye movement during the adaptation process has not been acquired. In this research, we developed reverse glasses with eye tracking system inside. The eye-tracking system is composed of micro-patterned transparent optical sensors. Using this device, we obtained the movement of eye when the subject is wearing the reverse glasses.
