Download the project and execute run.sh (for linux) or run.bat (for windows) under dist folder, and let program run on background while you work.
The program will count your keystrokes and mouse clicks and log total counts after each hour and day in myp.txt file under your home directory.
I guarantee, You will be surprised when you see counts :), and respect to keyboard and mouse for their endurance.
A special thanks goes to JNativeHook for their library I used in this project to listen system to get keyboard and mouse events.
Are you asking my performance since I started computer for preparation of this blog entry? Here
