Event based user activity detection

[VAN0]

I'm in a process of optimizing my script to converts message boxes into notification-like popup.

My last challenge is to bring down CPU usage to 0 while detecting click/key press in external application to hide my popup without interrupting.

Currently I'm using this in a loop:

For $i = 0 To 255
                If (_IsPressed(Hex($i), $hUser32_Dll)) Then
                    closePopup()
                    ExitLoop
                EndIf
            Next

It works fine, however it uses 3% CPU

 

I know I could use _WinAPI_UnhookWindowsHookEx for $WH_KEYBOARD and $WH_MOUSE events, which I've tested, and it works wonderfully.

But perhaps there is a better method available?

 

Thank you.

Is the goal to suppress your popup if the user does any activity, or specific key presses or mouse clicks?

One idea that comes to mind is just check idle time. 

_WinAPI_GetIdleTime()

My idea was to show a popup, and hide it after 10 sec, however if user continue working with that program, like pressed any key, or clicked, then hide the popup so it doesn't interfere.

_WinAPI_GetIdleTime() wouldn't work, because it's triggered by mouse move, also, I'm trying to avoid using the loop, as it seems to be the most inefficient. So far, I'm achieving 0% CPU usage by registering $WH_KEYBOARD and $WH_MOUSE event listener while popup is opened and deregistering it when it's closed.
