"The mouse and keyboard were invented before the Internet even existed. Since then, countless technological advancements have allowed for much more efficient human computer interaction. Why then do we continue to use outdated technology? Introducing Gmail Motion -- now you can control Gmail with your body," Google said while announcing Gmail Motion.
Google said that the Gmail Motion uses computer's built-in webcam and Google's patented spatial tracking technology to detect users movements and translate them into meaningful characters and commands. Movements are designed to be simple and intuitive for people of all skill levels.
Google also offered a printable PDF format guide of sample gestures. The gestures help users to familiarize with basic functionality of Gmail Motion. More over, Google recommended some safety precautions before applying the Gmail Motion.
"First, make sure to clear the area around you. Second, try to take short breaks every 30-40 minutes, just as you would if you were typing. And finally, take time to stretch after each session to give the muscles you'll be using some relief."
Just like any other Google Experiments, there is a link to "try the Gmail Motion." On clicking this link Google shows "April Fools!" Ya, you read it right. It is Google's 2011 April Fool prank.
