SYSTEM AND METHOD FOR 3-DIMENSIONAL INTERACTION BASED ON GAZE AND SYSTEM AND METHOD FOR TRACKING 3-DIMENSIONAL GAZE

摘要

A 3D interaction system and method based on gaze and a 3D gaze tracking system and method are provided to determine a gaze direction by using the image of a user's eye and determine a gaze depth by using an interval between centers of pupils obtained from the images of user's both eyes, thereby quickly determining a 3D gaze. A 3D(Three-Dimensional) interaction system(100) based on gaze comprises a display unit(10), two light sources(12a,12b), an image acquisition unit, a first signal processing unit, a second signal processing unit, and a third signal processing unit. The display unit displays at least a 3D image. The light sources are aligned in both sides of the display unit. The image acquisition unit acquires both eye images of a user gazing the 3D image. The images of both eye include reflecting points formed by the light sources and the images of two pupils within both eyes. The first signal processing unit produces the reflecting points inputted from the image acquisition unit and a gaze direction and a gaze depth from the images of the pupils. The second signal processing unit determines the gaze of a point which the user gazes within the 3D image from the produced gaze direction and the gaze depth. The third signal processing unit executes the command of the user according to the determined gaze.
