The newly introduced Google’s ‘Gmail Motion’ is nothing else than an April Fool joke. Google claimed that with this ‘Gmail Motion’ services user can control Gmail user interface with the movement and gestures of his body. The claim was just unbelievable; but when any user clicked on the "Get the Gmail Motion" he came to know that he became the victim of April Fool joke.
But this joke by Google stimulates the guys at Institute for Creative Technologies and they worked out something real out of this April Fool Joke.
They are demonstrating their solution in the video - the Software Library Optimizing Obligatory Waving (SLOOW) - and show how it can be used with a Microsoft Kinect sensor to control Gmail using the gestures described by Google.
