Interactive Sensor Technology
The TC70x/TC75x 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 your digital maps depending on your physical orientation.
•
Light Sensor - Used to detect ambient light and adjust the screen brightness.
•
Proximity Sensor - Uses to detect presence of nearby objects without physical contact.
In order to take advantage of these sensors, applications use API commands. Refer to the Zebra Android EMDK for more information.
