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 already stored. After the gesture is finished, it is matched up against templates in the database and given a percentage of how much it matched it’s closest template
