‘Apple Glass’ could project AR directly onto a wearer’s retina

Apple is researching how “Apple Glass,” or other future Apple AR devices, could skip tiny screens altogether, and instead use micro projectors to beam the images straight onto the wearer’s retina.

Apple may soon have an entirely different meaning for its term “retina display.” Rather than a screen whose resolution is so good our eyes can’t distinguish individual pixels, there may not be a screen at all.

“Direct retinal projector,” is a newly-granted patent, that claims this projecting right into the eyes could be best for AR. Specifically, it could prevent certain ways that watching AR or VR on a headset can cause headaches and sickness.

“Virtual reality (VR) allows users to experience and/or interact with an immersive artificial environment, such that the user feels as if they were physically in that environment,” says the patent. “For example, virtual reality systems may display stereoscopic scenes to users in order to create an illusion of depth, and a computer may adjust the scene content in real-time to provide the illusion of the user moving within the scene.”

We know all of this, but Apple wants to set the stage for how typical AR/VR systems work, and why there are problems. Then it wants to solve those problems.

“When the user views images through a virtual reality system, the user may thus feel as if they are moving within the scenes from a first-person point of view,” it continues. “However, conventional virtual reality and augmented reality systems may suffer from accommodation-convergence mismatch problems that cause eyestrain, headaches, and/or nausea.:

“Accommodation-convergence mismatch arises when a VR or AR system effectively confuses the brain of a user,” says Apple, “by generating scene content that does not match the depth expected by the brain based on the stereo convergence of the two eyes of the user.”

You’re wearing a headset and no matter how light Apple manages to make it, you’re still conscious that you have…
