Earlier quoted context omitted.

The Kinect works by projecting an infra-red grid on to the room so you can't use 2 of them in the same space (unless you modify the hardware somehow)

Could you synchronize two Kinect devices on one clock and then toggle the display/capture of that grid every odd or even 10ms span? So, only one grid is displayed and processed during its 'slice' of time, with the grids strobing rather than continuously projected. Software-only, or would that result in too jerky of a motion capture?

How about slightly different wavelengths of infrared?

For the frequency of the news about Kinect hacking I get the feeling that the homebrew software for Kinect will soon boost with much more professional features than the official software, esp. since it's pushed with games.

As Microsoft sells these things highly subsidized to claim profit with on the games I see lot's of conflict potential.

I hope he links up two or three of these to form fuller 3d models of a room.

Maybe you could turn one on, capture the positions of the dots, and then turn the other on, and somehow guess which one was which when the 3d mesh changes (from motion)?

I'm not in this space or planning on investing time into this but I just wanted to say Kudos to Microsoft for creating something that developers are excited about again... even if they didn't indent to do that. I'd start hacking on this if I wasn't invested in a different direction.

I can see indie game developers using Kinect to do realistic motion-capture in games.

I recall seeing this issue pop up in the 'making-of' DVD for Alan Wake by Remedy. When they made their first big game, Max Payne 1, they did the storytelling in the form of a comic due partially to budget constraints. Using a hacked Kinect and cheap PC hardware, game developers could capture a huge range of motions and use video editing software to overlay the required graphics onto the captured motions.

Idea: Please, someone somehow need to attach via software a Kinnect and a 3D printer.

I have a 3d printer, but not a Kinect. Range data is not very good at all at creating 3d models. What you really want is that plus a turntable so you can get multiple views. To get a printable model, you need a mesh with no holes. A single range image has lots of holes, so you can't really print the image without filling them by taking multiple images and matching them. That said, I do think I'll make a 3d scanner ba…

Hi, I'm thinking of getting RepRap. Do you find your printer brings you any business opportunities ?

Last week, a guy from Microsoft Research said that they got multiple cameras in the same space working, but that others in the lab had problems with it. Seems to depend on the setup, but is obviously possible
