Multitouch prototype: First video

I didn’t post in a time, but here is the first multitouch video. It lacks of projector yet, but works.

Multi touch interface (part 5): First FTIR test

Here my first FTIR test. It works really well. I didn’t used a visible light filter yet, but you can see it works.

Multi touch interface (part 4): Almost done

Finally some pics of my almost finished prototipe. The electronics are feeded by 12 Volts, and it works fine.

I was doing some quick tests with my mobile phone to check if it generates blobs, and yes, it does blobs barely touching the screen. Them are soft, but it’s due to my mobile cam cause it have IR filter. I couldn’t do tests with the PS Eye without filter, but judging by the images that I have taken with it, I think it will capture the blobs very clear. 

Now I only need a projector, but if I can’t get one soon I will try with an standard monitor and a mirror to do some real tests.
