Abstract:
A system for detecting a gazing point of a user in a three-dimensional (3D) space based on a virtual screen is provided. The system includes at least a processor and a wearable device, the wearable device further comprising an external camera arranged for capturing images of the user's field of view, and two internal cameras arranged for capturing binocular images of the user's left and right eyes. The processor is designed to determine the gazing point of the user based on a virtual screen. The coordinates of the pupil center as determined according to the images from the internal cameras are mapped to the images from the external camera based on a left and a right mapping relationships, which further mapped to the virtual screen as an intermediate screen for calculating the 3D coordinates of the gazing point.

Claim (Index 9):
The method of  claim 1 , wherein the virtual screen is an imaginary screen positioned at a distance equivalent to the predetermined distance between the user and the calibration screen.
