NUI Group announces Multitouch Technologies book release!

bookcover

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.

If you’re unfamiliar with NUI Group, I suggest reading the about page http://nuigroup.com/log/about/. NUI Group is currently the single best resource for multitouch technology and hopefully will

Super Cool Multitouch Actionscript Fluid Solver

Eugene has just ported Memo’s fluid solver work to AS3 http://blog.inspirit.ru/?p=248. With the source now out, I was able to quickly add multitouch support and it works great! Thanks to cyandesign and simpleex for keeping me on my toes.

A couple notes, the touchlib AS3 classes had to be corrected since they currently don’t send dX and dY values which the fluid solver needs to calculate directional velocity. Other than that, things went fairly smoothly and took little time to make touch sensitive.

Bloom – Multitouch Music Application

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.

MultiKey Updates…it works with a mouse too!

No, I haven’t forgotten about the other programs that I first started on. I’m still developing Audioshape Sequencer as well as Musical Squares, but recently I have made some big changes/additions to the MuliKey application. I think all of the changes are great improvements and will allows for much more functionality and experimentation within a simple application like MultiKey.

First, if you’ve seen the first versions, you’ll notice that the look has changed slightly. I’ve gotten rid of the background (for now) to allow for best performance. Also the border of the keyboard has changed a bit so that it is easier to resize the keyboard. Previously the border width made it somewhat hard to select the keyboard for moving,

New application: Audioshape Sequencer

Audioshape Sequencer is modeled after Tangible Sequencer and originally inspired by Nicolas Clavaud.This application works with a mouse and/or multitouch table (touchlib/tuio simulator or other TUIO program).

There are three main things to know about the program.

  1. There is the shape (square),
  2. signal (transparent orange shape),
  3. and sensor (Blue dot on square. Pink when activated).
