The U.S. Patent and Trademark Office has officially granted Apple a patent related to the Apple Vision Pro, which covers a relative inertial measurement system with vision correction. Such systems are used to compensate for the mismatch of the eye chambers within the headset, which can lead to nausea when what happens in the VR headset doesn't match the motion happening in the real-world environment.
Apple notes in the patent background that traditional virtual reality and augmented reality systems may not be able to distinguish the motion of the user or user's body parts from the motion of a driving reference object.
For example, a user wearing a traditional VR or AR device can sit in a vehicle, and the vehicle can accelerate from a stop to a high speed, while a user wearing a VR or AR device sits in the vehicle without moving inside the vehicle (e.g., the user relative to the vehicle The reference object has no relative motion). Since a traditional VR or AR device cannot separate the motion of the user's body from the motion of the vehicle, the traditional VR or AR device can attribute the motion of the vehicle to the user. In this way, images displayed to a user on a VR or AR device may appear to the user as if the user is running through the scene at the same speed and in the same direction.
A similar phenomenon occurs with regard to angular motion. For example, a user wearing a traditional VR or AR device might be in a turning vehicle, but the user might not actually turn their head when the vehicle is turning. Traditional AR or VR devices may not be able to separate the movement of the user's head (eg, not turning) from the motion of the vehicle (eg, turning). As a result, the turning motion of the vehicle may be attributed to the user, and the image displayed to the user on a VR or AR device may appear to be turning or spinning, even though the user is not turning their head. This discrepancy between the relative motion of the user within the vehicle and the motion the user observes through the scene can lead to nausea for the user.
In WWDC23, Apple officially announced that the head display product is called "Apple Vision Pro", runs a new operating system "visionOS", and is equipped with M2 and a new R1 chip.
In terms of design, the Vision Pro looks like ski goggles and diving glasses. Its frame is made of aluminum alloy and includes sensors, cameras, displays, and computing components cooled by fans. The headband and earmuffs are made of pure fabric and can be bent to fit various face and head shapes. In terms of lenses, Apple has cooperated with Zeiss to customize, and the prescription lenses produced can be magnetically attached to the display screen, which is convenient for myopic people to use the headset. In terms of screen, it is equipped with two 4K micro OLED screens, with a total of 23 million pixels, and each eye has more pixels than a 4K TV.
Apple 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, allowing Vision Pro to have a smoother experience. At the same time, in order to process the information of 12 cameras, 5 sensors and 6 microphones, Apple also brought a brand new R1 chip, so that the image can be synchronized to the Vision Pro screen within 12 milliseconds, almost without delay. It's like everything is happening right in front of you.
