About Built-In Sensors

A built-in accelerometer, digital compass (magnetometer), and gyro sensor enable you to use the following functions.

Screen rotation using the built-in accelerometer

When you rotate your VAIO computer, the built-in accelerometer automatically detects the movement and rotates the computer screen to portrait or landscape orientation depending on the computer orientation.

Pressing

(the rotation lock button) on your VAIO computer allows you to enable/disable the screen rotation.

Navigation assistance using the built-in digital compass

The built-in digital compass provides navigation assistance on compatible apps by detecting the direction your VAIO computer is facing.

App operation using the built-in gyro sensor

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.

Hint

You need to calibrate the built-in digital compass when the app does not show the direction correctly. [Details]
