ReDollar
A gesture recognizer in javascript .
This is a refactoring version of dollar.js ( http://depts.washington.edu/aimgroup/proj/dollar/dollar.js ), so named "Re"+"dollar".
Of course , ReDollar is more simple and more powerful.
Simple Example
var dollarOne = new RD.DollarOne();
// name: string, it's gesture's name
// gesturePoints : 2D array, it's gesture's key-points
// [ [x1,y1], [x2,y2], [x3,y3], ... [xN,yN] ]
dollarOne.addGesture(name, gesturePoints);
// userPoints : 2D array, like "gesturePoints".
// It's key-point of user's stroke-gesture
// matched is mathed gesture or null (no matched)
var matched = dollarOne.recognize(userPoints);
