The computer revolution has made it easy for people with little to no technical training to use a computer for such everyday tasks as typing a letter, saving files, or recording data. But what about more imaginative purposes such as starting your car, opening a door, or tracking the contents of your refrigerator? "Physical Computing" will not only change the way you use your computer, it will change the way you think about your computer?how you view its capabilities, how you interact with it, and how you put it to work for you. It?s time to bridge the gap between the physical and the virtual?time to use more than just your fingers to interact with your computer. Step outside of the confines of the basic computer and into the broader world of computing.
