The Samsung GALAXY S II comes with Voice Talk. Voice talk and voice commands have changed the way we use smart phones. Control your smart phone with voice commands and even dictate SMS messages. You do not have to type the text message any more. Just say it and then send it with send voice command to recipient. Watch really amazing videos on how smart phone was being used in the past and how people are using the smart phone today (specially when it comes to Samsung Galaxy S 2).
Google introduced Gmail Motion, allowing users to control Gmail using gestures and body movements. That was for April fools day but the Software Library Optimizing Obligatory Waving (SLOOW) and FAAST (Flexible Action and Articulated Skeleton Toolkit) are the solutions which show how this technology can be used with a Microsoft Kinect sensor to control Gmail using the gestures described by Google. This project uses OpenNI coupled with FAAST and was made by Evan Suma and the folks at Mark Bolas’ MxR Lab at the USC Institute for Creative Technologies.
