The basics of building a multitouch table
posted Apr 16th 2011 12:25pm by Mike Szczysfiled under: multitouch hacks
Here is a bare-bones multitouch table setup. We looked in on [Seth Sandler's] multitouch work a few years ago when he completed the MTmini build. He’s scaling up the size a bit with the MTbiggie, and showing you how easy it is to put together. The demo rig seen above is just a couple of chairs, a sheet of acrylic, a mirror, a projector, a computer, and a diy infrared webcam.
The rig uses ambient infrared light to detect the outlines of your fingers when they touch the acrylic surface. A webcam with an exposed camera film filter feeds an image of the infrared light received below the surface to the computer. The incoming video is processed using Community Core Vision, where each individual point is isolated and mapped. Once the data is available the sky’s the limit on what you can develop. [Seth's] demo packages include a mouse driver, some physics applications, an Angry Birds implementation, and a few others. See for yourself in the video after the break.

Multitouch project roundup

It seems that ever since Microsoft unveiled the Surface table the concept of multitouch has really started to snow ball. We’ve been fans ever since seeing [Jeff Han]‘s original research in this area. Earlier today we looked at a multitouch rear projection TV project but what else is out there? After the break, we’ve got several multitouch projects you might be interested in.
The MTmini sounds perfect for those with a limited budget and time. With just a simple webcam and a few software programs you can build your own multitouch device. Although this technique isn’t as elegant as IR applications it appears to get the job done.
CUBIT is taking a unique approach by offering an open source programmable multitouch unit for sale. Their Touch Kit product comes in two flavors, Do It Yourself, for $800 and The Full Meal Deal, for $1480 with most of the hard work done for you.
We couldn’t talk about multitouch without giving some mention of Apple. They deserve credit for bringing this technology to the masses through the iPhone. If recent patent filings are any indication, you can look for multitouch on your mouse and even the entire laptop interface in the future. Just last week Apple hackers presented Lux, a multitouch framework for OSX.
