A Gyroscope is one of the many sensors present in smartphones. It uses the earth’s gravity to measure the orientation of the mobile phone's screen.

As you may know, all iOS devices have accelerometer sensors (plus magnetometer and gyroscope on some devices). However, as web developers, we didnt have access to such sensors until now.

MEMS gyroscopes are benefiting from MEMS inertial-sensor improvements. Invensense, STMicroelectronics, and VTI Technologies are major MEMS gyroscope manufacturers for the consumer electronics market.

Murata recently introduced the SCC2000 series of combined accelerometer and gyroscope sensor devices aimed at use in automotive and industrial applications.

“Our innovative 3-axis digital gyroscope represents a true leap forward in ST-led consumerization of MEMS sensors, enabling major improvements in ever more popular motion-sensing user interfaces ...
