Not content with keyboard and voice search, Google has gone one step better for mobile devices by launching Handwrite for Mobile and Tablet Search.Yes, search by handwriting. So if you're at a bus stop, for example, you get to search by 'writing' letters with your finger anywhere on the (touch) screen. Sounds like fun? Here's how you get started.Go to Google.com in your mobile browser, tap on 'Settings' at the bottom of the screen and enable 'Handwrite.' After you've saved the setting, you may need to refresh the homepage to see the feature. Once enabled, tap the Handwrite icon on the bottom right corner of your screen to activate the writing surface. Write a few letters and some autocomplete options will appear below the search box. If one of the options is what you’re looking for, just tap it to search. For longer queries, you can continue writing and use the arrows next to the autocompletions to move the right one into the search box. This isn't an 'either or' option, with Handwrite designed to complement rather than replace typing. You can still use the keyboard at any time by tapping on the search box. As for compatibility, Google says it works best in Chrome and is enabled for iOS5+ devices, Android 2.3+ phones and Android 4.0+ tablets – in 27 languages.
