[Unity Web demo](http://aymericlamboley.fr/blog/wp-content/uploads/2014/07/index.html).\n\nThis is an adaptation of the original C# code for Unity.\n\nIn the demo, only one point-cloud template is loaded for each of the 16 gesture types. You can add additional templates as you wish, and even define your own custom gesture templates.\n\n![](http://aymericlamboley.fr/blog/wp-content/uploads/2014/07/multistrokes.gif)\n\nAbout\n-----\nThe [$P](http://depts.washington.edu/aimgroup/proj/dollar/pdollar.html) Point-Cloud Recognizer is a 2-D gesture recognizer designed for rapid prototyping of gesture-based user interfaces. In machine learning terms, $P is an instance-based nearest-neighbor classifier with a Euclidean scoring function, i.e., a geometric template matcher. $P is the latest in the dollar family of recognizers that includes [$1](http://depts.washington.edu/aimgroup/proj/dollar/index.html) for unistrokes and [$N](http://depts.washington.edu/aimgroup/proj/dollar/ndollar.html) for multistrokes. Although about half of $P's code is from $1, unlike both $1 and $N, $P does not represent gestures as ordered series of points (i.e., strokes), but as unordered point-clouds. By representing gestures as point-clouds, $P can handle both unistrokes and multistrokes equivalently and without the combinatoric overhead of $N. When comparing two point-clouds, $P solves the classic [assignment problem](http://en.wikipedia.org/wiki/Assignment_problem) between two bipartite graphs using an approximation of the [Hungarian algorithm](http://en.wikipedia.org/wiki/Hungarian_algorithm).
