Google recently launched Gesture Search Android app, that allows you to search your device by drawing letters or numbers. Gesture Search 2.0 provides a faster search experience on your device.
According to Google, Gesture Search lets you quickly access contacts, applications, settings, music and bookmarks on your Android device by drawing letters or numbers. It continuously refines search results as you add each gesture, and becomes better as it learns from your search history.
This android app also supports multilingual content–that can be an arbitrary mix of English and 11 other languages including Simplified Chinese, Dutch, French, German, Italian, Polish, Portuguese, Russian, Spanish, and Turkish.
To access multilingual content, instead of writing native characters of each language, you can still write letters using romanization of these languages, such as Pinyin for Simplified Chinese.
Gesture Search 2.0 can be downloaded from Google Play and requires Android 2.1 and above.
