The Hoverstop mouse helps you minimize the amount of time you hand spends on the mouse. First it detects if your hand is on the mouse. It then monitors if you are actually using it (clicking, scrolling). If you are not using it for more than 10 seconds, it will vibrate softly to remind you to take your hand away and relax. This will give you many mini breaks per hour. Meanwhile you continue to work normally thinking, reading, without being disturbed. If you need the mouse again, just pick it up to resume work.
