text: If you decide to park your car in the garage and put away the keys, you'd really be able to see how nice it is to just walk to your destination rather than drive, it's a great way to realx and to just enjoy yourself.            I personally, think that it would be a bad idea to use this kind of technology in shools to help students learn. This is mainly because of errors that the computer could make, or other outside factors. If the program makes changes to the lesson due to facial expressions alone, then it would make an unbelievable amount of mistakes. In case you still aren't sure what im getting at ill explain in more detail below.
