Motion Sensing Technology replaces Voice recognition

I have been interested on and off in accelerometers for nearly ten years. They have been used in car airbags for a while now but we are finally seeing them being linked to computers to sense motion. Products like the Nintendo Wii and Motion Sensing Tablet PC result. I hate computer games generally but tried the Wii and loved it. Just think what the gaming experience will be like when Playstation 3 comes with a motion sensing pad. I think we are more likely to see motion sensing replace the keyboard than voice recognition now. The combination of mechanical engineering and computer will revolutionise how we exercise (see the Wii) to how we interact with all the machines in our lives, maybe non contact cars, computers and remote controls. It will be a more fulfilling and interactive experience all round.
