Scratch Technology Works As Long As You Don’t Have An Itch
Researchers at Carnegie Mellon University have come up with an idea that would allow you to use scratching as an input method. The idea is that any surface can be turned into an input device allowing you to turn down the music at a party by scratching the wall anywhere in the room in a certain way or doing basic commands on your computer by scratching your desk. In theory it is a pretty good idea but probably one of those that we will never see make its way into our daily lives.
