Abstract
A head-mounted viewable device includes a display configured to display and project a virtual scene image to a user's eye, a VR optical lens configured to construct an optical path between the display and the user's eye for allowing a virtual scene image being observed by the user's eye, and an eye-tracking system configured to detect a sight direction of the user's eye and adjust a display position of the virtual scene image based on the detected sight direction. The eye-tracking system includes at least one light source configured to project the detection light and a receiving module configured to receive the reflected detection light reflected to determine the sight direction of the user's eye. The receiving module is positioned at a side of the VR optical lens and arranged to face towards the user's eye such that the detection light reflected by the user's eye is directly received by the receiving module.
