Chrome Beta 21 represents a major milestone for the browser. Its support for getUserMedia API, a big first step for WebRTC (a new real-time communications standard) allows web sites to access the camera and microphone natively, without any plug-in. The getUserMedia API also allows sites to create cool new experiences that weren’t previously possible in the browser. For example, try Magic Xylophone created by Stinkdigital in your Chrome beta 21. You can play it just by waving your hands in front of the camera. Although WebRTC is in its beginning stage and its use isn’t common yet, this new technology lays the foundation for a new, more efficient way of communication. [Via]
