Power Management; Display Orientation - Motorola MC75A User Manual

Interactive Sensor Technology
This section describes the functionality of the Interactive Sensor Technology (IST) feature on the MC75A.
The IST supports the following features.
•
Power Management – manage power by configuring IST to control switching on/off the backlight, control
suspend mode of the MC75A by monitoring motion and orientation.
•
Display Orientation – switch the screen orientation to either landscape or portrait depending on the MC75A
orientation.
•
Free Fall Detection – monitors free fall duration and records the time and type of the drop event.

Power Management

The MC75A orientation and motion sensitive data can be used as an indicator of MC75A usage and can be used to
manage the battery power of the mobile computer. For example, IST can be configured to control the backlight on
and off functionality or go into suspend according to a user gesture by placing screen facing down. It can also be
used to keep the MC75A active while it is in movement to prevent it from quickly going into suspend mode while in
use.

Display Orientation

The screen can be rotated between portrait and landscape modes automatically, depending on the physical
orientation of the MC75A. For example, if the MC75A is rotated 90° counterclockwise, IST rotates the display
counterclockwise 90° so that the screen display appears correct.
This functionality is achieved by monitoring screen angle and rotating the display to counter any changes. IST only
rotates the screen in multiples of 90°.
