A hand gesture recognition system for replacing a mouse


A Computer Vision based hand gesture recognition system that replaces the mouse with simple hand movements. It’s done at the School of Computing, Dublin City University, Ireland.

Sometimes the future of gesture recognition can become clearer by examining an application that will definitely NOT hit the market running. Why on earth would anyone prefer to wave their hands in the air and click on empty space with their index finger instead of feeling a solid mouse underneath your hands? I just don’t get it. If it’s supposed to be a technology showcase, then okay, they managed to get something up and running, bravo!

I think that generally speaking, people are enthusiastic about human-computer interaction if it feels good , because it’s usable (effective, efficient, economic), pleasing to the senses, or in some other way beneficial to their concerns. I imagine that this virtual ‘mousing’ is none of the above. Maybe if they changed it to a pistol gesture, where you shoot with your thumb, it would get slightly better. But I would have to be able to launch a quick barrage of shots, say 4 or 5 per second, for this to be of any use in a first person shooter game. There’s a nice challenge for you, guys :-)
