METHODS AND APPARATUS FOR ESTIMATING POINT-OF-GAZE IN THREE DIMENSIONS

摘要

Methods for determining a point-of-gaze (POG) of a user in three dimensio ns are disclosed. In particular embodiments, the methods involve: presenting a three-dimensional scene to both eyes of the user; capturing image data in cluding both eyes of the user; estimating first and second line-of-sight (LO S) vectors in a three-dimensional coordinate system for the user's first and second eyes based on the image data; and determining the POG in the three-d imensional coordinate system using the first and second LOS vectors.
