How does mobile know about its orientation?

Açıklama:

This video explores the science and technology behind the sensors used for identifying the orientation of a mobile device. At 00:00 the introduction sets the stage, followed by a discussion of the accelerometer at 01:00, its microstructure at 02:30, and a 3‑axis version at 03:30. The gyroscope is covered at 04:20, including the Coriolis effect at 04:27 and its microstructure at 04:45, with a 3‑axis version at 05:20 and a note on gyroscopic drift at 05:40. Sensor fusion is explained at 06:00, and the magnetometer is introduced at 06:50, with the Hall effect at 07:05 and its microstructure at 07:20. The video concludes with advantages and disadvantages at 07:40.
