What is the primary use of an accelerometer and gyroscope in devices?

The primary use of an accelerometer and gyroscope in devices is to represent current position and movement. These sensors play a crucial role in how devices perceive their orientation and movement in space. An accelerometer measures acceleration forces, which helps in detecting changes in velocity and tilt, while a gyroscope monitors angular rotation, allowing the device to understand how it is turning or changing its orientation.

By combining data from both an accelerometer and a gyroscope, devices can accurately track their position in three-dimensional space. This functionality is foundational for various applications, such as motion-based gaming, augmented reality, and navigation systems, where understanding movement and orientation is essential for delivering a seamless user experience.
