Accelerometer and gyroscope
1 like1,731 views
The document discusses the accelerometer and gyroscope sensors found in smartphones and their uses. The accelerometer measures device orientation and gravity while the gyroscope detects rotation along three axes. Together, they provide precise six-axis motion sensing by combining the three axes of each. This detailed motion data is used for camera image stabilization, gaming input, navigation apps, and general user interface interaction.

- 4. Gyroscope + AccelerometerThe combined data from the accelerometer and the gyroscope provides detailed and precise information about the device's 6-axis movement in space. The 3 axes of the gyroscope combined with the 3 axes of the accelerometer enable the device to recognize approximately how far, fast, and in which direction it has moved in space.
