We’ve seen accelerometer features implemented before on Windows Mobile devices such as VueFLO in the HTC Advantage, and even the old Tilt Control add on for the old iPAQ Pocket PCs years ago. Generally the accelerometer implementations haven’t been anything that spectacular or user-friendly. The Touch Diamond is about to change that.

The “Teeter” game that the Touch Diamond includes, is extremely cool. Basically you tilt the phone and the little ball on the screen rolls down the hill as if it was really responding to gravity. What’s more is that when the ball hits the walls of the maze, you can actually feel a slight vibration in your fingers as if the ball has mass and is transferring force through the on-screen walls to your hands. Very impressive!

The accelerometer is also used in the Opera web browser and the Photo Album to re-orient photos and web pages so that the bottom is always pointing towards the source of gravity.

Hopefully there’s an API for accelerometer usage somewhere in there so that other third party developers can make use of it.
