Our online glossary is here to help you make sense of the terminology used in the cell phone industry.

What is "Accelerometer"?

An accelerometer is a built in component that controls the tilt and motion of a screen on a device, while also having the ability of detecting shakes, tilts, and other motions a device may make. The most common use of the accelerometer is to automatically change the screen when a device is tilted from portrait to landscape mode.

Other important uses are for game controls (such as steering in racing games) and gestures such as shaking a device to shuffle music.
