Abstract: A display device includes a display, an image beam shifter, and a light guiding component. The display generates an image beam. The image beam shifter receives the image beam and generates a projected image beam. The light guiding component receives the projected image beam to transport the projected image beam to different positions of a target zone in sequence. The image beam shifter projects the projected image beam to different positions of the light guiding component with time division.

Abstract: A head mounted display includes a tube, a first light beam generator, a second light beam generator, an image capturer and a controller. The first light beam generator is disposed outside the tube and projects a plurality of first light beams to a first range of a target area. The second light beam generator is disposed inside the tube and projects a second light beam to a second range of the target area. The image capturer captures an image on the target area to generate image information. The controller receives the image information and performs an eye-tracking operation according to the image information. The second range is a center range of the target area, and the first range is a surrounding range of the target area.

Abstract: A head mounted display apparatus and a display method for an eye-tracking cursor are provided. The display method for an eye-tracking cursor includes: projecting a display image, and starting a cursor tracking function; detecting a first staring point of eyes on the display image; setting a first cursor on the first staring point; and detecting a first visual distance between the first staring point and the eyes, and adjusting a dimension of the first cursor according to the first visual distance so that a value of a view angle of the eyes with respect to the first cursor is equal to a preset value.
