The delicate ting of wonderful crystal stemware is as much a part of the strategy of having fun with wonderful wine as is the satisfying plop of a cork being extracted. Over the course of growing an AR headset, Apple has thought of contact panels, voice activation, and head gestures as enter methods, and a variety of applications from mapping to texting are being prototyped. Yury Petrov, a former analysis scientist at Facebook-owned Oculus, is now serving as a "analysis scientist" at Apple. Apple in May 2020 acquired NextVR, a California-based company that mixed virtual actuality with sports, music, and entertainment, providing VR experiences for watching live events on VR headsets from PlayStation, HTC, Oculus, Google, Microsoft, and other manufacturers.

Current headset prototypes are said to weigh around 200 to 300 grams, but Apple is aiming to cut back the final weight to a hundred to 200 grams if technical issues could be solved, which would make the headset lighter than present VR units. Apple has also employed staff which have worked on digital or augmented reality merchandise at Microsoft and Lytro.
Employees coming from the HoloLens workforce would have experience creating a sophisticated augmented actuality headset. Apple's AR/VR workforce consists of several hundred engineers from throughout Apple, all of whom have expertise in digital and augmented reality.
