CHAPTER 8 SPECIAL CONSIDERATIONS
Touch Panel User Interface Considerations
When developing applications for a touch panel interface, touch panel activation only by the ball of the finger
means there are limitations to what the user interface of an application can expect of a worker
•
User interface elements such as buttons, that require activation by a bare finger tip on the touch screen
should not be smaller than 10 mm x 10 mm (as opposed to 5 mm x 5 mm if a stylus were an option).
•
Do not put user interface elements close to the edge of the display. They’re hard to activate and they
might not be fully covered by the protective overlay. Keep the touch points at least 2 mm in from the
edge.
Tips for Improving Battery Life
To improve the life of the battery:
•
Set the display backlight to turn off quickly and reduce the display brightness.
•
Set the keypad backlight to turn off quickly.
•
Set the wearable computer to suspend when not in use and maximum CPU performance.
•
Set the WLAN radio to save maximum power.
After making these settings, they can be saved in Registry files to make them cold-boot persistent.
