Abstract:
1. A gaze-based three-dimensional (3D) interaction system, comprising: a display unit configured to display a 3D image having objects with different depths; two light sources respectively aligned at both sides of said display unit to provide lights; an image capturing unit configured to capture an image of both eyes of an operator gazing at the 3D image, the image of the both eyes of the operator showing glints formed by the lights provided from said two light sources and two pupils in the both eyes; a first signal processing unit configured to calculate a gaze direction to which the operator is gazing at the 3D image based on positions of two glints and a pupil at one of the eyes on the image of the both eyes and a gaze depth at which the operator is gazing at the 3D image based on a distance between the two pupils in the image of the both eyes; a second signal processing unit configured to determine a gaze of the operator on said 3D image based on the gaze direction and the gaze depth; and a third signal processing unit configured to execute a command the operator intended according to the determined gaze.
