Beep sound generator when some software is idle

You can choose to do any one of these, no need to do them all: 1. I use MS OneNote for notetaking using touchpen on tablet. Make OneNote to generate beep sound if I am not writing something on it for 3 seconds. The beep sound should go on continuously until I write something on it again. 2. Or if you can make this for other notetaking program other than OneNote, then that's OK too. 3. Or just make a software that will make the tablet create some beep sound if my touchpen is not touching on it for 3 seconds. The beep sound should go on continuously until I write something on it.
