A little bit ago, we had heard that the HTC Vive was delayed due to a new technological advance. It was said we'd hear about it at CES, and alas, it has come to be.
That advancement is a front facing camera which is on the new;y reveal headset, allowing users to switch out and see what is in front of them if they so wish. In a press release it was said this would help in:
Being able to take a seat, find your drink, and carry on conversations without removing your headset is only the beginning of what's possible
This seems like a rather elegant solution to a real issue. However, the idea of carrying on a conversation while you have a headset on…that seems a little…disconcerting for the other party.
