Bigscreen VR appears to be an accessory that relies on an external device for compute and head tracking and power. As far as I can see it's basically just a tiny OLED display you strap to your face. With AVP, Apple is taking a bet that the accessory nature of previous attempts is why this product category failed and so they're trying to embed the compute and make it wireless. Unfortunately for utopian visions of VR goggles, we're running up against the limit on how small computers can be, so the idea of a standalone headset as light as Bigscreen VR is essentially science fiction at this point. Not to say it won't happen, but if that's what it'll take for this product category to take off then your optimism is misplaced.
