Does this setup work?

[Evan Collins]

Hi,

I'm an architecture thesis student at Cal Poly San Luis Obispo in California, and I'm trying to develop an installation for our public end-of-the-year thesis show, using the Kinect to create an interactive touchscreen to display each of our projects. I've been having trouble finding how to exactly accomplish this, and was wondering if I could use this hack to create a rear-projected touchscreen on a taught fabric surface using the kinect placed in front of the screen. We are actually planning on purchasing about 20 Kinects, and renting as many projectors to create this installation. It would be very helpful if someone could let me know if this set up is possible using the Kinect bundle. 

Thanks, 

Evan Collins

Hi Evan,

Ok, that should work but, but, consider one kinect per computer (and projector) and make the software with large input areas (if you use a large area for each Kinect you will probably have hand resolution, not finger). You have another option as well, make the fabric elastic (stretched but elastic) and do something like this : http://www.youtube.com/watch?v=9iYwIuznXII . It is a very rough (but with a very nice idea) Roberto Ulloa (a user of SKT) did. You can do the same with LKB (and we do recommend using LKB instead of SKT). With LKB you can connect 2 kinects in the same PC but Kinect have a ONE per USB HUB requirement so you have to be sure that the ports in the pc support 2 kinects (trial and error works...). We do interactive floors and walls all the time, takes some practice but works. The main advice is, as said earlier, to test the surface you want to use, check the resolution you get and then make the development considering the dimensions you can interact with (and the stability). 

Another option you can use is interaction at a distance. With LKB you can send the users hands as TUIO objects to any application that receives them. You can also use the full skeleton of users. 

Good Luck!
