VOA is a little application which runs in background and reacts on user activities with vibration.


– Vibrate always on touch events (mouse down, or mouse up)
– Vibrate only if SIP is active
– Vibrate on Key press (hardware keys)
– Adjustable vibration (duration in ms)
– configuration over command line parameters
– fully event based, so only battery consumption while vibrating
– No runtimes needed (pure C++ application)
– Works with WM 5+ (not 2003)


– Fix for volume buttons (HTC Diamond), the keyboard part of the code is completely disabled if onkey 0 is set
