DIY Multitouch display: first test

Checkout www.diniro.net
This is a short clip of the first test of my DYI multitouch display. There's still an offset beetween the finger touch points and the detected touch points, this is due to the very unstable setup and the lack of SW calibration. The display will be improved also with a compliant surface that will require to press less hard on the display in order to detect touches.

Hi where did you get your sample from?

[blaxwan]

Hi, what sample you're referring to?

[GuntaGuru]

The projection material sample. I have been trying to get hold of a decent size sample for a LONG time. If you can help I would greatly appreciate it.

[blaxwan]

Hi, as I said in the other comment the sample was provided by Peroni, you'll find more info on my website (it is not possible to post links on youtube comments)

Wow, congratulations, I watched some videos of Jeff Han (Perceptive pixel), and some of Microsoft Surface.

And you did it, impressive.

Now I have some questions:

1- How expensive is your setup?

2- What software or operative system are you using? Linux?, Vista? or Mac?

Thanks

[blaxwan]

Thanks a lot!

Actually I paid €25 for the plexiglas, €16 for the LEDs and €230 for the webcam with some different optics, but quite any webcam will work (saving a lot of money!). The projection surface sample was kindly offered by Peroni, the video projector was not mine :o). The OS was WinXP but I'll switch soon to Linux. You'll find all the answer you need to build one on NUIgroup site, of course check also my site!

I'm geeting sick of people refering to touch- screen (multi-touch or not) as "apple stuff".

Btw, cool display.

What was the software at 2:02?

[ktstrayer]

Any idea how to hook up the wiimote? I am not a programmer.

[CeekayProductions1]

I think you can use the wii remote as an IR camera, but the wii remote can only tack 4 points at the same time

[chris82o]

since your using a projector the room must be pretty dark great idea and good job putting it together

[ktstrayer]

Now, I would like to try this, but I have a webcam that I don't want to screw up. Are you able to use a Wii remote as the IR camera? after all, this is how it works is tracking IR points.
