I'm working on an MD4 application that I would like to have automatically log out after a period of inactivity--meaning no human interaction with the MD4 touch screen. The concept would be similar to a screensaver that turns on after say 30 minutes of inactivity and requires a pin code to wake up. Is there any status code or anything else in the system that I could make use of? Would it be possible to have a System Information Channel with a Display Input Active value that is True any time the screen is being touched (ex MD4) or a button is being pushed (ex MD3)?
