Google has begun work on a new item on a long list of technologies designed to make applications running on the Web more competitive with those that run natively on a machine's operating system: an interface to know which way is up.

The orientation interface plumbing is being built into the WebKit browser project that underlies Google's Chrome and Apple's Safari, according to a Google's Chrome issue tracker.

The technology would let the browser provide an application with hardware-supplied information about which way a computing device is being held, information that's particularly useful for mobile games that rely on that for a user interface. For example, tilting a device can turn it into a steering wheel or a tabletop on which a marble rolls.
