The N95, Nokia’s Smartphone, includes a built-in accelerometer. This was originally only used for video stabilization and photo orientation (to keep landscape or portrait shots oriented as taken).
Nokia Research Center has recently allowed an application interface directly to the accelerometer, allowing software to use the data from it. Nokia has released an application to demonstrate this.
Third-party programs have already begun to appear, including RotateMe, which will automatically change the screen orientation when the phone is tilted and Lightsaber, which causes the phone to make the sounds of the Star Wars Lightsaber when waved through the air.Another third-party program which has also used the built-in accelerometer is Glogger VS2 , a camera application which can automatically detect camera shake and reduce the possibility of taking a blurry image.
