In the demo below, only one unistroke template is loaded for each of the 16 gesture types. You can add additional unistrokes as you wish, and define your own custom unistrokes.

Make strokes on the grey canvas. If a misrecognition occurs, add the misrecognized unistroke as an example of the intended gesture.

The <canvas> element is not supported by this browser.
