The latest version of Google Goggles will kick into action without your lazy arse doing a thing. All you have to do is enable a setting that allows Goggles to work in the background each time you take a photo.
If Goggles recognises something, it will send you a notification. If it doesn’t you’d never know it was there, except for your battery haemorrhaging power a little faster. If you want to use the latest version of Google Goggles (1.6), you need to be running Android 2.1 or newer. Download it here. [Google]
