Support for eye tracking, new patents reveal new features of Apple's future smart glasses
CTOnews.com, December 7 (Xinhua)-- Apple has received a total of 47 technology / appearance patents in today's updated list of approved patents by the United States Trademark and Patent Office (USPTO). After roughly reading these patents, foreign science and technology media PatentlyApple specially introduced a technology patent in the field of smart glasses.
The Apple patent shows that the smart glasses come with screens that can be used to display computer-generated content. Waveguides can provide computer-generated content to users for viewing, while allowing users to view the real world. The eye tracking system (Gaze tracking systems) can monitor the user's line of sight.
The display of the head-mounted device can provide left and right images to the left eye box and the right eye box. The left and right waveguides can be used to transmit the left and right images to the left and right eye boxes. The left and right waveguides may be transparent. This allows real-world images to be viewed through the left waveguide from the left eye box and through the right waveguide from the right eye box.
The reference associated with the left and right infrared reflectors can be monitored using a left and right gaze tracking system camera so that the camera can be calibrated. The reference may be formed by an infrared reflector or other patterned portion of the reference structure.
CTOnews.com also learned that Apple also received three design patents for AirPods Pro and two design patents for HomePod Mini today. Apple's design patent 971880 is an unknown design.
