The HTC Vive has already a front facing cameras, so there you are: a VR headset which can do AR. Of course with only one low-res camera, it's very poor AR. And

The HTC Vive has already a front facing cameras, so there you are: a VR headset which can do AR. Of course with only one low-res camera, it's very poor AR. And it's tethered.. When most people talk about AR, they're talking about untethered AR.. The tethered --> wireless --> autonomous transitions won't be easy though (probably needs to track the eyeball to reduce the power needed).
