Now this is both cool AND useful. We’ve seen this before where the user wears an HMD like the Oculus Rift, they have a computer in a backpack, and they walk around the room with the help of tracking infrared cameras.
In our opinon, what makes this version work really well is that by using a wireless HDMI connector system, it’s no longer necessary for the user to be debillitated with cumberson wires or heavy machinery on their back. By having a big enough room, they are also able to have enough space for a convincing virtual environment. They are even taking advantage of some spatial tricks to make sure the user’s virtual movement doesn’t overrun the physical space (i.e. walk through physical walls).
This really opens up some interesting doors. For example, this could mean that just about any HMD with infrared reflective nodules mixed with infrared cameras could be a viable and inexpensive alternative for CAVEs with the added benefit of real collaboration between users. Imagine several people sharing the same visual space yet getting their own point of view of the envrionment. See what you think!
