Which of the following best describes the function of an accelerometer in a mobile device?
A) Provides multi-axis motion sensing
B) Provides precise navigation based on longitude, latitude, and altitude
C) Determines the amount of ambient light around the device
D) Detects the orientation of the device
E) Forces me to drive faster than I really want to
The answer: D) Detects the orientation of the device
An accelerometer is a motion sensor that can measure acceleration, even when an object is at rest. By using these measurements, a mobile device can determine which way is “up” and properly display the screen in the correct orientation.
