According to a report from Ming-Chi Kuo, Apple will begin to manufacture your headset of virtual reality by the end of 2019 or early 2020. The first generation of the glasses of virtual reality will depend on the iPhone, using the services of computing, rendering, internal connectivity and location.
To depend on both the iPhone will achieve some advantages, such as a headset much more lightweight and comfortable to use, as they will not have within itself all the elements needed to function properly, as other headsets, like the Oculus Go. The counter: how much battery you will need to use the iPhone to be able to enjoy the experience of AR.
The deadlines indicated by Kuo are similar to those published by Bloomberg a few years ago. It is still not too clear how useful will be the glasses of virtual reality, but Apple is making a big bet with this product.
