According to Kuo’s report, “We predict that Apple will launch AR HMD [head-mounted display] devices in 2Q22. The device will provide a video see-through AR experience, so the lens is also needed, and Genius is also a key supplier.”
That being said, at the moment there have been multiple rumors about said device. This is because in addition to an AR headset, Apple is also rumored to be working on a mixed reality headset that could debut this year. This headset is apparently going to debut ahead of the AR glasses and will mostly be marketed towards developers to encourage them to build an ecosystem for when the AR glasses eventually launches.
We have also heard rumors that prototype testing for the AR headset has fallen behind, although a Q2 2022 launch does seem like a reasonable timeframe for Apple to try and get things up and running before then.
