Sensors
This computer is equipped with four sensors (acceleration sensor, gyro sensor, magnetic sensor,
ambient light sensor), and you can use these sensors with any software that is compatible.
As the accuracy of each sensor output is dependent on the operating environment and other con-
ditions, the results should only be used as a reference.
The acceleration sensor, gyro sensor, and magnetic sensor are located at the bottom left of the
LCD. The detection results of each sensor may vary depending on how you are holding the com-
puter, the application software you are using, and other factors.
l

display screen based on the ambient light sensor. You can configure the automatic adjustment
function as follows.
