Enabling new classes of applications with Pointer Lock
Tuesday, September 25, 2012
Moving the web forward includes enabling
new classes of applications
. Today’s
Chrome Stable release
advances this effort with the inclusion of the
Pointer Lock JavaScript API
(often called Mouse Lock). Now, 3D applications such as first-person games can allow users to control their perspective naturally with the mouse, without moving outside the window or bumping into the edge of their screen. Try it out for yourself in this 3D,
first-person shooter demo
created by our friends at Mozilla.
While games are fun, these capabilities also empower other types of applications such as medical and scientific visualization, training, simulation, modeling, authoring packages, and more. We're excited to see recent web platform technologies such as
WebGL
,
Web Audio
,
Fullscreen
,
WebSockets
,
Gamepad
, and
Pointer Lock
combine to be greater than the sum of their parts. Game developers have an excellent platform on which they can deploy rich games with all the benefits of the instant-on, auto-updating, linkable, shareable, and searchable web.
As always, Chrome will automatically update itself to include these latest enhancements. If you haven’t tried Chrome yet,
give it a spin
!

Announcing Movi.Kanti.Revo, A New Chrome Experiment
Wednesday, September 19, 2012
Earlier this year at Google I/O, we gave developers a
sneak peek at Movi.Kanti.Revo
, a new sensory Chrome experiment crafted by Cirque du Soleil and developed by Subatomic Systems that brings the magic of Cirque du Soleil to the web through modern web technologies. The full experiment, which allows users to follow a mysterious character through a beautiful world of Cirque du Soleil performances, was launched today at the
Big Tent event
in New York City.
The experiment was created using just HTML5, and the environment is built entirely with markup and CSS. Like set pieces on stage, divs, images and other elements are positioned in a 3D space using CSS. To create movement,
CSS animations
and
3D transforms
were applied making the elements appear closer and further away. Everything is positioned and scaled individually to create a highly realistic interactive environment. In addition, the experiment uses HTML5 <audio> to play music and sounds.
Movi.Kanti.Revo breaks with the tradition of keyboard or mouse navigation; instead users navigate through an interactive Cirque du Soleil world with their gestures. To accomplish this, the experiment asks users for permission to access their web cam using the new
getUserMedia
API. With this new API, the experiment renders the camera output to a small <video> element on the page. A facial detection JavaScript library then looks for movement and applies a CSS 3D transform to the elements on the page, making environment move with the user.
Because this experience was built using just markup, it works in the browser across all devices. The experiment takes advantage of the rich capabilities possible on mobile devices, like the
accelerometer
to navigate through the world.
To learn more about how this experiment was built, check out the new
technical case study
or join us for a special Google Developers Live
Behind The Divs
event on September 20th at
8:30am PDT /15:30 UTC
where we’ll be talking to the engineers behind the project.
Head over to Movi.Kanti.Revo at
www.movikantirevo.com
to check things out, and be sure to open Chrome’s
developer tools
to see what’s going on behind the <div>s!
