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.
In order to take advantage of these sensors, applications use API commands. Refer to the Zebra Android
EMDK for more information.
