How did you interact with your gadgets 5 years ago? Chances are, with a Mouse and keyboard. Maybe some buttons, or a trackpad here and there. But how about today? Probably with a mouse and keyboard, still, but we'll bet that's not all. Does your phone have a touchscreen? Likely. Can it do voice recognition, too? Bet it can. Do you have a Wii or a PS3? Then you’d better add motion control to the list.
