Abstract
A binocular see-through AR head-mounted display device and an information display method therefor are disclosed. The present invention uses the scene depth image and the user stared point to calculate the position of the target object stared by the user and maps coordinates to the screen coordinate system to determine the overlapping position of AR information. In addition, the present invention can tolerate small changes of human eye sight, and the AR information can be stably stacked in the same position with good robustness. The present invention can distinguish the target object stared by the user from the background, and when the user eye sight is put on different parts of the target object, the AR information is still superimposed at the same position without frequent movement with changes of the eye sight.
