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 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.
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. See
for more information.
