The SmartNav is a system designed to control a mouse cursor with your head. You set the scary looking thing on top of your monitor, slap a reflective dot on your head, and you're good to go. Unfortunately you're not good to click on things, so you'll have to install a foot pedal or something to make that happen. The unit costs between $240 and $400 depending on the setup, and is guaranteed to make you look cool (see video). I just wish they would have made it so that you could click on things without the need for another device. Maybe if you just bob your head like a chicken twice really fast then that can count as a click. Or make like you're trying to bite your ear. I don't know, something.
