The trace command system searches for contacts, bookmarks, music, and other apps on an Android phone through drawn alphabet gestures executed on the touchscreen. It's also capable of refining searches by adapting to your search history. For instance, if Jay-Z is one of your most popular searches, drawing the letter “J” on the screen will automatically place Jigga at the top of the results query. Dope. While Gesture Search is available on the Android Market, there has been no announcement concerning a future update. Maybe Google has plans of integrating it into the new Android Ice Cream Sandwich OS.
