Google launched Gesture Search in March and the tool has proven pretty useful for people who want to search by tracing letters on an Android smartphone. Gesture Search 1.2 launched August 11 with a potentially useful but really silly looking feature called the "double flip." Users of Gesture Search can flip their phone over and back to start the Gesture Search app, a Google Labs experiment. This gestures obviates the need to trigger Gesture Search from a home screen shortcut.
