@kentray1985: From the hands-on impressions I've heard, the actual HoloLens display shows a pretty limited field of view (FOV). Something similar to viewing something on your cellphone about 6 inches from your face. So all the holograms will appear within that window, ie "what you're looking at", but will not in your periphery, so it seems unlikely in practice you will get the same sense of full-environmental impact they show using the third person camera.
Moreover, and the part I'm more disappointed with how they've treated, is HoloLens doesn't seem to have object occlusion. So if you have your hand, finger, or any other dynamic object in the environment, the hologram will always appear painted on top of it, even if it's supposed to look like it's under/behind it, or partially obscured by it. As an example in the demo above, you never see a fireball or enemy shown behind the subject (behind from our camera perspective), but always between him and the camera. And the one situation where it might have occurred, he moves behind the couch and pins himself against the wall to ensure he is the bottom layer. Then he moves out of view, behind the camera to the other side of the room, to ensure he is the bottom layer over there too. And of the five or so videos I've now seen of HoloLens demos, they do these kinds of things every time!
As someone who has watched a lot of magic shows, I'm used to seeing careful choreography there to mask the gimmick behind the illusion. Unlike magic, HoloLens is actually real, and it's impressive tech, so I wish they would present it more accurately and not resort to such trickery.
It's a very cool demo, I just wish they were being more forthcoming about the actual experience. At this point they really should be showing these from a first person perspective instead of third. They keep having the subject/player carefully choreograph themselves around the third person camera to avoid object occlusion, which would break the illusion but at least be more truthful.
Also, they allude to the limited FOV with this simple, but clearly well-crafted sentence at the beginning: "We also have this custom camera that can see a full view of every Hologram. Dan sees all the Holograms he is looking at, but this camera will show you all of the action on stage."
I can take a misleading demo or two, but at this point it's just ridiculous.
