The BBC sez: Replace your mouse with your eye. It’s a premise with promise, but what do you think? Could you accurately move things around your screen with your flickering eye movements? It just might replace aching wrists with strained eyes. I can just imagine the cursor twitching back and forth across the screen until you go back to the closet and dig out the old mouse in disgust. But maybe I’m just closing my eyes to the march of progress.
