The long awaited Multitouch Technologies book authored by members of NUI Group (http://www.nuigroup.com) has officially found it’s first release! As one of the co-authors of the book, I am proud to see a final initial version come to fruition. The book, which consolidates articles from the NUI Group Wiki, includes sections on how to build Multi-touch devices, multitouch software resources, a glossary of terms and more. I  believe, as the book develops further, this will be the best resource for multitouch information on both the web and in print.

Well, it’s about time I released another application right? If anyone has ever played Bloom on the iphone, I’m sure you’ll recognize my port from iphone to table.
If you’re not familiar with bloom, it’s a very simple music creation application. Press anywhere on the screen to create circles that grow and ‘bloom.’ As they fade out and re-appear, they play a note. The note is based on the x-axis. As you move right, the notes go higher.

New video of the new system that loads and unloads applications. Also, the desktop is now sending out OSC message to PureData to create some sounds based on finger number and position on screen.

New video showcasing the final table at work. The software is all a work in progress and new releases will be coming soon of all applications as well as new ones. If you like the video, please pass it on. If you don’t like the video, please pass it on anyway. Enjoy!

Rosco Projection screen is an inexpensive projection screen that seems to give pretty good results. There’s a few places online you can buy it. I ended up purchasing it from rosebrand.com. All places sell by the yard and the the minimum size is 55″ by 1 yard. The price is $15 per yard at 55″ width. I ended up buying both the Rosco Black and Rosco Grey to see which would work best with my setup.

Screen comes packaged on a roll.

I went to home depot and picked out some wood that would be good enough for the inside framing of the table. I tried to get something light weight and sturdy. The main reasons for the frame is to keep the table sturdy and also make it so the walls of the table will be square, flush, and have something to screw into. I measured out all the pieces in google sketchup and then had someone at home depot cut the pieces to size.

From the Google sketchup file I created, I measured and fabricated the top frame that will hold the LEDs, acrylic, silicone (compliant surface), and projection layer. The top frame consists of two pieces; the top piece, which will fit the acrylic (in the center), along with the silicone rubber and projection material on top, and also the infrared LEDs alongside the acrylic and the bottom piece that will screw into the top piece and rest on top of the final box.
