17 AUGMENT YOUR REALITY
You’re familiar with text search. You’ve heard of (or tried) voice search. Now it’s time for visual search! You don’t need to type or utter anything here, you simply point your smartphone or tablet at a building, restaurant, or shop, etc.— or click a picture with it. The phone then fetches the appropriate associated information from the Internet. The info could be descriptions, shopping deals, Wikipedia entries or reviews related to the targetted subject. Or gathering info off a business card by merely getting your phone to see it! Cool, yes? Well, that’s Augmented Reality. Popular AR programs on smartphones and tablets include Layar, Wikitude, Google Goggles and Junaio. But there are loads of excellent ones that could be more specific to your interests. These include Star Chart (astronomy), Peaks (mountains), ARSoccer (football) and Theodolite (navigation and hiking).
