you've just described a depth camera and its potential usefulness.
Not lightspace. Lightspace is the tech demo using 3d depth cameras ALONG WITH projectors, to "CREATE AN INTERACTIVE ENVIRONMENT". It's about creating, not about input, and it's not simply about 3d cameras which we've had for years now.
If all you wanted to do was say 3d cameras are exciting then fair enough.
If you wanted to prove to me how lightspace was a useful concept, you have not done so.

Having a 3d camera is one thing, figuring out useful things to do with that data is something else. Gesture interpretation and human interaction with the environment is the novel part of the demonstration. The value in this is it shows any surface or volume can be interactive, and is much more cost effective than the other options. It requires no gloves or extra accessories and is much more robust than anything that would only use a regular camera.
It is very much about input and natural human/machine interaction. You can't even define the concept, so of course you don't think it's useful. But everyone else can see that having a computer track your every move and react to anything that is controllable is useful. The projector is just a way to define and show users the interface options and provide feedback, it's not really the real advanced part of it.
I'm never going to convince you it's useful because you simply don't understand it. So far your responses have proven to me that you don't even have a cursory understanding of the field because you can't tell me what the researchers have done that hasn't been done before. Let's just say that the consensus from the people that matter is this demonstration shows a lot of interesting research principles with lots of possible applications in information manipulation and dynamic man/machine interaction, and you can continue being ignorant all day.

Yup, well put. Exactly what I've been trying to explain.
Like talking to a wall indeed.

The inclusion of projectors is a main tenet of the technology. It says so in their scientific article and in the video, and in the text underneath it. Without the projector, you are simply talking about 3d depth cameras, which is not lightspace.
If you agree with him, then you are not addressing lightspace in any form. Like I said earlier, lightspace is like a computer. It has a display (projector), input (depth sensing camera), and processing center.
I said that lightspace was useless because it was limited by the projected area. The scientist in the video says "you can have applications like you're lost and you hold your hand out and it shows you directions, or arrows appear on the floor". This is impossible without projectors everywhere you go, and their display WILL be occluded whenever someone blocks the lightstream.
The post you quoted referred only to the possibilities of depth camera input, which, to its credit is a boon. It's a new interface. However, there is a distinction between "lightspace" and 3d depth camera input, much like the difference between a computer and a keyboard.
