Who Doesn’t Like Lava Lamps?

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.

Flash + Reactivision = Slider: A Dynamic Multiplayer Game

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 number of players. The lower the score, the better; the first player with a score of 12 ends the game.

Flocking around with AS3 and Multitouch

For a while I’ve been interested in emergent behavior where simple rules can create complex behavior. One of the most known examples of such behavior is Craig Reynolds ‘boids’ where a few simple rules can recreate the flocking behavior of birds.

I recently came across a great and clean example of some boids code by soulwire (make sure to check out his whole site; it’s great). Since we’ve seen various examples of this behavior on multitouch tables (like on the iBar), I decided to add some basic touch support to soulwire’s example. So, now we have it…multitouchable boids!

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.
