Claim 3:
4. The eyeball tracking method of claim 3, wherein tracking the left infrared light source through the left tracking camera and tracking the right infrared light source through the right tracking camera to form initial frame tracking images comprises:
respectively controlling the left tracking camera and the right tracking camera to simultaneously shoot a left eye and a right eye of a user to obtain corneal reflection points;
calculating sight line vectors by taking the corneal reflection points as reference points, the sight line vectors being vectors respectively from pupils in the left eye and the right eye to the corneal reflection points; and
calculating characteristic information of the left eye and the right eye according to the sight line vectors to form the initial frame tracking images.
