Give Hitachi's new PC a hand
It's pretty unlikely anyone who's ever used a computer hasn't been annoyed enough to give it a rude finger gesture but Hitachi's come up with a PC that can interpret hand gestures via infrared sensor and use them to operate the computer. For instance, moving your hand in the air from left to right would scroll through document pages. Hitachi figures the system could be useful for recipe-hunting housewives with food-covered hands or surgeons who want to instant message while in the middle of cutting people open. We still think this mouse thing is working out for us just fine.
