KB55: Additional hardware requirements for button zones

Summary

There is no additional hardware required to include a fully-functional button zone in your Display Design file or to run it on your Player. Typically, customers that include button zones in their design use a touch-screen for user input at the Player. However, a touch-screen behaves in much the same way as a traditional mouse, trackball or touch pad and a button zone responds to the clicking action of any of these hardware devices in the same way.
