It’s no secret Apple is hard at work on augmented and virtual reality devices, with a report from Bloomberg in January claiming Apple is working on an ultra-high-end, pricey headset that could hit stores in 2022. Apple has for years worked on technology that uses eye tracking to fully render only parts of the display where the user is looking. Apple's rumored VR headset is also said to feature dual 8K displays with eye-tracking technology that could offer resolution far beyond any current commercial VR headsets on the market today.
