220-802 · Question #636

Which of the following mobile device features is responsible for shifting the device display orientation?

The correct answer is B. Gyroscope. The gyroscope in a mobile device detects rotational movement and angular velocity, enabling the device to determine and respond to changes in physical orientation.

Why each option

The gyroscope in a mobile device detects rotational movement and angular velocity, enabling the device to determine and respond to changes in physical orientation.

ADevice calibration

Device calibration is a maintenance process for tuning sensor accuracy, not a sensor feature that detects orientation.

BGyroscopeCorrect

A gyroscope measures the rate of rotation around one or more axes, allowing the device's operating system to detect when the device is being rotated and trigger a display orientation change accordingly. This sensor is distinct from the accelerometer and is specifically responsible for sensing rotational motion.

CGPS

GPS determines geographic location using satellite signals and has no role in detecting device physical orientation.

DAccelerometer

The accelerometer measures linear acceleration and gravitational force, which can assist with tilt detection, but the gyroscope is the sensor credited for rotational orientation shifting in this context.
