Andrew Sculley: So the headset or HMD must be small for comfort like a pair of glasses. Hence it really had to have a microdisplay. The possible used example I want you to imagine you're sitting in a meeting room with some of your colleagues and chairs around the table and a number of empty spaces, all of which you can see through the pair of glasses you're wearing, which is the headset.

Imagine that some of your colleagues aren't in the room, but they have a video camera taking their video and sending it to your headset, so the people not in the room actually appear to you as if they’re in chairs around the table. Now in a still image, you call this is a photoshopped image, but this is a video of what the person is doing at that moment. And when you add sound, you have some virtual attendees at your meeting. So what do you need for something like this?
