Search your Android phone with written gestures

As mobile phones become increasingly powerful and can store more data, we've introduced new methods of search to get you to your content faster, such as search suggestions or search by voice. But sometimes, typing to get to the right search suggestion takes too long, and you may be in a quiet environment where speaking a query is inappropriate. Today we're pleased to announce Gesture Search, a new Google Labs application for Android-powered devices running Android 2.0 or above in the US. Gesture Search lets you quickly find a contact, an installed application, a bookmark or a music track from hundreds or thousands of items, by simply drawing alphabet gestures on the touch screen.

Say you want to call your friend Anne. Just open Gesture Search and draw letter �A�, and Gesture Search returns a list of items that have words starting with �A�. If your handwriting isn't all that neat, that's okay. If the "A" you draw looks a bit like an "H", as seen in the bottom left corner of the screenshot, "H" results will be brought up as well. If needed, you can also erase a query by crossing it horizontally: left to right erases the entire query, and right to left removes the last letter or space in the query. Now you can either scroll down the list to find Anne or write more letters to refine the search.



Additionally, Gesture Search improves search quality by learning from your search history, so Anne's contact info will jump to the top of the list the next time you write "A".

To download Gesture Search, search for it in Android Market. You can get more information on our Google Labs page. And as this is a Labs launch, we are particularly eager to get your thoughts and feedback in the comments below!

Update 10:19am Pacific Time 3/17/2010: Gesture Search is now available for Android 1.6.
