220-802 Question #636: Real Exam Question with Answer & Explanation
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.
Question
Which of the following mobile device features is responsible for shifting the device display orientation?
Options
- ADevice calibration
- BGyroscope
- CGPS
- DAccelerometer
Explanation
The gyroscope in a mobile device detects rotational movement and angular velocity, enabling the device to determine and respond to changes in physical orientation.
Common mistakes.
- A. Device calibration is a maintenance process for tuning sensor accuracy, not a sensor feature that detects orientation.
- C. GPS determines geographic location using satellite signals and has no role in detecting device physical orientation.
- D. 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.
