A built-in accelerometer, digital compass (magnetometer), and gyro sensor enable you to use the following functions.
When you rotate your VAIO computer with the LCD screen folded, the built-in accelerometer automatically detects the movement and rotates the computer screen to portrait or landscape orientation depending on the computer orientation.
The built-in digital compass provides navigation assistance on compatible apps by detecting the direction your VAIO computer is facing.
The built-in gyro sensor detects angular movement of your VAIO computer, which allows you to perform actions with apps, such as a game app.
You need to calibrate the built-in digital compass when the app does not show the direction correctly. See Notes on Built-In Sensors for more information.
