JS Motion Detection

This project tries to provide as a basis for other motion-detection apps, by separating the framework from its implementations.

The app uses WebRTC, HTML5 Canvas and some math, and is refactored out of the Magic Xylophone by soundstep. You can learn more about the process fom Romuald himself on Adobe Developer Connection and his blog post.


Any child element you add inside <div id="hotSpots"></div> will automagically work as a hotSpot, which means it will fire motion events on itself with extra data upon motion detection.

You could control its appearance & position with CSS, and hook to the motion events with jQuery / plain JS.
