AR library that you can use right now! Developed in Javascript-based

Currently we use Flash to implement Augmented Reality (AR) on web sites. However, in recent years, an AR based on JavaScript has been developed. “JSARToolKit”, which we recommend today, is also an AR library that works on JavaScript. In the near future, we are expecting that AR will work simultaneously on smart phones with web applications, because progress is being made in HTML5 implemented WebRTC.
