Can't see the mouse in the video? Why, that's because it's an invisible mouse (of sorts), dubbed Mouseless. The folks over at Fluid Interfaces Group, MIT Media Lab, have come up with a setup that uses an IR camera and IR laser to determine the position of your hand and detect clicks, essentially turning your hand into the mouse itself. The best part of this project is that the total cost of the prototype was about $20, which should be well within your budget, assuming the necessary technical wizardry isn't an issue for you. Check out a video of it in action after the jump, though the mouse cursor does seem to a track a little slow. It'll be interesting if such technology were made standing into every notebook in the future, though. Would you want to use a mouse in this manner?
