The Gesture Search Android app from Google Labs that lets you search by writing out characters on the touchscreen of your device, has been updated. A new version of the Gesture Search Android app ( Version 1.2 ) now includes a new motion gesture.

By doing a double flip, or flipping your phone away and then back, you can start Gesture Search at any time. This eliminates the need to activate Gesture Search from a home screen shortcut.  See this in action in the video above.

You can turn the feature on or adjust its sensitivity in Settings. Google also fixed some bugs and improved usability by adding accessibility support.

It is available for Android-powered devices running Android 1.6 and above, and can be downloaded in Android Market.
