Apple Vision Pro new patent: reducing motion sickness and eye fatigue

CTOnews.com, Aug. 4, according to a list published by the US Trademark and Patent Office (USPTO), Apple recently obtained a patent for Vision Pro head display technology, which can reduce motion sickness and visual fatigue.

In augmented reality, virtual reality and mixed reality (AR / VR / MR) experiences, due to differences in physical positioning between sports and the real world, physical feelings are out of sync with virtual experiences, resulting in nausea, sweating, headaches and dizziness.

When releasing its Vision Pro headset, Apple said it could significantly reduce motion sickness by combining high-resolution displays with ultra-low latency.

Apple says it can reduce the delay to 12 milliseconds by processing all images through a proprietary R1 chip.

In its Vision Pro patent description, Apple also addressed another factor that affects motion sickness-a phenomenon known as visual convergence regulatory conflict (VAC).

The cause of this phenomenon is that when we look at a point, our eyes rotate so that the point of view falls on the retina, while when we look at a nearby object, our eyes usually look inward, and the visual axis of the distant object diverges, which leads to focusing conflicts.

In its patent, Apple details ways to deal with VAC to reduce visual fatigue. The patent description is very professional, and its essence is to combine the screen and the camera to change the eye's perception of the image.

The translation part of CTOnews.com is as follows

The optical engine includes a series of optical waveguides with holographic or diffraction gratings, which generate a beam of light at an appropriate angle and position by moving the light source, and then guide the light into an additional optical waveguide with a holographic film layer recorded with a diffraction grating. to expand the aperture of the projector and project it to the position required by the holographic combiner.
