Yelp Sneaks Augmented Reality Into iPhone App

Posted in: Apple, apps, augmented reality, iPhone, Phones, Software, Today's Chili

Just a day after we published a feature about smartphones accelerating the development of augmented reality, Yelp sneaked a secret AR feature into an update of its iPhone app.

Exclusive to iPhone 3GS owners, the feature is accessible through an Easter egg, which is activated by shaking the handset three times. A message will appear reading, “The Monocle has been activated,” and then a Monocle button will appear in the upper-right corner. Tapping that button will launch your iPhone camera, and digital overlays of business listings, accompanied by star ratings, appear on screen. The app presumably draws its geo-aware powers from the iPhone 3GS’ digital compass and GPS. Mashable demonstrates the feature in the video above.

We use the word “sneak” because Apple doesn’t provide an open API to access live video from the iPhone’s camera, making it impossible for developers to provide AR apps without hacking the software development kit. We’ve put in a query to Yelp requesting clarification on how its developer coded the AR feature.

If Yelp submitted a hacked version of its iPhone app and Apple approved it, it’s unlikely this victory will last very long. In May, Wired.com reported on the first developer to use an Easter egg to trick Apple. Apple had rejected his app Lyrics because it contained swear words, so he filtered them and added an Easter egg enabling users to remove the filter. That app is no longer in the App Store. The developer said Lyrics was “pulled temporarily” due to licensing issues, but the app still has not returned.

However, even if Apple pulls the Yelp app for sneaking in AR, it would likely become available in the near future. Brad Foxhoven, co-founder of augmented-reality company Ogmento, said Apple has told him the next version of the iPhone OS (3.1) “would make [AR developers] happy,” implying the live-video API will become open, and legitimate AR apps will become available very soon.
