According to patentlyapple, the U.S. Patent and Trademark Office has officially granted Apple a patent 11751366 related to a head-mounted device (Apple Vision Pro) that can provide a passive cooling system that uses the surface of optical components to manage heat without affecting the user. adversely affects the visual information displayed.
The lens is coated with a transparent thermally conductive material, such as silver nanowires. Such heat dissipation layers can provide excellent thermal conductivity, transmittance, flexibility, flat transmission, low cost and angular color stability. Thermal layers can passively manage heat by increasing the surface area for effective heat dissipation. In the second granted "Multiple Inputs for Rotating and Translating Digital Crown Module" patent 11747919, we learn that Apple is considering using its digital crown for future smart glasses, as shown in the patent below.
More specifically, Apple points out that the FIG.8A patent drawing shows the operation of HMD #850 including smart glasses including frame #860 and user interface #854, input device/digital crown #820 and gaze tracking camera #858. FIG.8B patent diagram shows a specific use case of user interface #803 of HMD #850. User interface #803 may include multiple graphical icons or applications #805. The user interface can be controlled by the input device/digital crown #820 and gaze tracking camera #858 individually or in combination.
The second input can then be provided by determining the user's gaze. For example, a gaze tracking camera #858 may determine that the user is looking at or visually tracking a specific icon #813 and may perform a function based on that determination.
At WWDC23, Apple officially announced that the head-mounted display product is called "Apple Vision Pro", runs a new operating system "visionOS", and is equipped with M2 and new R1 chips.
In terms of design, Vision Pro looks like ski goggles or diving goggles. Its outer frame is made of aluminum alloy and contains sensors, cameras, displays and computing components cooled by fans. The headband and headphone mask are made of pure fabric and can be bent to fit a variety of face and head shapes. In terms of lenses, Apple cooperated with Zeiss to customize and produce prescription lenses that can be magnetically attached to the display, making it easier for myopic people to use the headset. As for the screen, it is equipped with two 4K micro OLED screens with a total of 23 million pixels. Each eye is allocated more pixels than a 4K TV.
Apple has designed a unique dual-chip design for Vision Pro. The main chip is the familiar M2, which is responsible for visual algorithms and image information processing, giving Vision Pro a smoother experience. At the same time, in order to process information from 12 cameras, 5 sensors, and 6 microphones, Apple also brought a new R1 chip, which allows images to be synchronized to the Vision Pro screen within 12 milliseconds, with almost no delay. It's like everything is happening in front of you.
