Abstract

Autofocus head mounted display device, including an imager (10) and an eyeball tracker (11). The imager includes a display element (12, 32, 52), an optical element (13, 35, 55) and a controller (14, 38, 58). An image light is projected to one of the eyeballs (15a, 15b, 37, 47, 57) of the user by the display element. The convergence or divergence of the image light is adjusted by the optical element through the controller. The image is presented at an imaging position in front of the eyeballs of the user. The eyeball tracker is disposed at the position in front of the user's eyes. Both left eye and right eye rotational angles are detected simultaneously, so as to determine a focus position of the user's eyes. The eyeball tracker is connected to the controller. The optical element is adjusted by comparing the imaging position and the focus position, and the imaging position of the image is moved to the focus position, thus preventing the user from having eye fatigue caused by long-term focus in the same position, and enhancing user of comfortableness.

Description

technical field [0001] The present invention relates to an auto-focusing head-mounted display device, in particular to a head-mounted display device with an eye tracker that automatically adjusts the imaging position by detecting the focus positions of both eyes. Background technique [0002] In recent years, with the continuous development of head-mounted display devices, the head-mounted display device can match the displayed image with the helmet or glasses worn on the user's head, and project it onto the display screen of the head-mounted device to form an image visible to the user , due to being close to the user's eyeballs, these images will be able to achieve a wide visual effect with a small display area, allowing the user to use the head-mounted display device to see the image to be presented. [0003] Furthermore, the head-mounted display device can form virtual images in front of the user's eyes by using the arrangement of optical elements, and these images, wheth...
