Ever since I saw Jeff Han’s lava lamp multitouch demo, I’ve been interested in ‘blobs’ or . There’s a great new HTML5/javascript demo of interacting with blobs (moving, splitting, merging, etc) http://hakim.se/experiments/html5/blob/03/.
The code is opensource under a MIT license so I decided to try porting the little application over to actionscript 3 to see how straight forward it is to port from javascript to as3.I know the trend is moving the opposite way – AS3 -> html5/js, but this is more a proof of concept of how easy it can …

Wall Pong is an interactive multi-player multitouch pong type game I wrote in AS3 a couple years ago. The aim is to get the ball into the opposing goal. You can see Wong within my Audiotouch OS software. I’ve been meaning to release the source code and game for quite some time and finally I had the chance to clean up the code (it still could use WAY more cleaning and probably re-factoring), but it’s in good enough shape for others to use.

I’m hoping to convert this version to use …

If you’re familiar with multitouch, you’re probably familiar with Jeff Han’s TED demo. In it, there’s an example of a lava application that shows an interesting use of multitouch.
A few months ago, I was trying to work on something similar.
The following is what I came up with. I never had the chance to finish and was only able to add mouse support at the time. So, here’s a preview of what might come to a multitouch screen near you at some point in the future.
It’s pretty slow since it …

On my last project I had to use a gesture to initiate an event. Due to this, I recently started experimenting in creating a simple multitouch version of some gesture engines that are available. I’ve come across three that are already available in AS3 and chose to start with the $1 gesture algorithm http://depts.washington.edu/aimgroup/proj/dollar/. It only seems fitting to start with this one since Andy Wilson of microsoft research (and many multitouch devices) had a hand in it’s development.
Like most algorithms, this one matches points drawn with a template that’s …

Before I started with multitouch, I was experimenting with interactive virtual gaming. As a result, for one of my final class projects at UCSD, I created a dynamic game I call ‘Slider’ which is a 1-3 player virtual hockey type game that adapts to the number of people playing.
This games uses reactivision software, along with Flash, to detect ‘fiducial’ or symbol block movements. The game is played by moving these symbols on a table. Players can enter and exit the playing field at any time. The game adapts to the …

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.
