Cat on keyboard

When your nice cat jumps on the desk and walks through your keyboard you most probably will clap your hands or do some other movements in order to make the cat escape from the computer's close environment.
In some cases a cat can write 'p[-pjnjnjk65r56zsazs' or other most meaningful strings.
In less successful cases the poor animal can order something from eBay, or sell your shares on the stock market.

Great News!!!
Chris Niswander of Tucson, Arizona developed a software called PawSense, which detects when a cat is walking across your computer keyboard, and knows how to ignore the key-strokes, which were not made by a human.

For his work he got Ig® Nobel Prize in 2000.

Great idea, funny topic, I like it.
