Interactive Sensor Technology
The device contains sensors that monitor movement, orientation and ambient light.
• Gyroscope - Measures angular rotational velocity to detect rotation of the device.
• Accelerometer - Measures the linear acceleration of movement to detect the orientation of the device.
• Digital Compass - The digital compass or magnetometer provides simple orientation in relation to the
Earth's magnetic field. As a result, the device always knows which way is North so it can auto rotate
digital maps depending on the physical orientation of the device.
• Light Sensor - Detects ambient light and adjusts the screen brightness.
• Proximity Sensor - Detects the presence of nearby objects without physical contact.
In order to take advantage of these sensors, applications use API commands. Refer to the Google Android
Sensor APIs for more information.
