Gadgets and Gizmos (India) - - COVER STORY -

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).
