The United States Patent and Trademark Office recently granted Apple registration a new technology that aims to reduce the sick feeling e eye fatigue in virtual reality (VR), augmented reality (AR) or mixed reality (AR/VR) devices.
The register, according to Patently Applemakes use of chip R1, whose role is to process all the Vision Pro images, bringing the delay down to just 12 milliseconds. Therefore, everything will appear to happen right in front of the users’ eyes, reducing the feeling of motion sickness.
In addition to motion sickness, Apple’s patent addresses another problem that is not as well known: the vergence-accommodation conflictalso known as VAC (vergence-accommodation conflict). Briefly, it can cause eyestrain and occurs when the brain is tricked into believing that a virtual object is far away when, in fact, the screen is close to the eyes.
To address this, the patent details a sophisticated system that combats VAC and lessens eyestrain by combining different displays and lenses that change the way images are seen by the human eye.
The technology also uses several optical waveguides with holographic or diffractive gratings that move the light from the sources, generating beams at the angles and positions necessary to illuminate the scanning mirrors.
The patent also presents several versions of a system that projects directly onto the retina and that can resolve the vergence-accommodation conflict in devices such as the Apple Vision Pro, for example.
If all these new features will reach Apple’s mixed reality headset, we still don’t know. Even so, this is an important step towards improving the user experience, making a difference among the products available on the market.
