Five featues comming soon in HTML 5


  1. The canvas element provides a straightforward and powerful way to draw arbitrary graphics on a web page using Javascript. Sample applications demoed at the show include a simple drawing area and a simple game. But to see the real power of the Canvas element, take a look at Mozilla’s BeSpin. Bespin is an extensible code editor with an interface so rich that it’s hard to believe it was written entirely in Javascript and HTML.

  2. The video element aims to make it as easy to embed video on a web page as it is to embed images today. No plugins, no mismatched codecs. See for example, this simple video editor running in Safari. And check out the page source for this YouTube demo. (As a special bonus, the video is demonstrating the power of O3D, an open source 3D rendering API for the browser.)
  3. The geolocation APIs make location, whether generated via GPS, cell-tower triangulation or wi-fi databases (what Skyhook calls hybrid positioning) available to any HTML 5-compatible browser-based app. At the conference, Google shows off your current location to any Google map, and announces the availability of Google Latitude for the iPhone. (It will be available shortly after Apple releases OS 3.) What’s really impressive about Latitude on the phone is that it’s a web app, with all the platform independence that implies, not a platform-dependent phone application.
  4. AppCache and Database make it easy to build offline apps. The killer demo is one that Vic first showed at Web 2.0 Expo San Francisco a few months ago: offline gmail on an Android phone. But Vic also shows off a simple “stickies” app running in Safari.

    (I love the language that Vic uses: “You can even store the application itself offline and rehydrate it on demand.”)

  5. Web workers is a mechanism for spinning off background threads to do processing that would otherwise slow the browser to a crawl. For a convincing demo, take a look at a web page calculating primes without web workers. As the demo says, “Click ‘Go!’ to hose your browser.” Then check out the version with web workers. Primes start appearing, with no hit to browser performance. Even more impressive is a demo of video motion tracking, using Javascript in the browser.
