Augmented reality coming to iPhone with iPhone OS 3.1

, , , ...

Some developers are leveraging undocumented APIs in iPhone OS 3.0 to create "augemented reality" apps for the iPhone. However, Apple has told at least one developer to wait until the 3.1 update, already in beta, before submitting such apps for App Store approval.

The idea behind augmented reality is that a live video view—in this case, taken from the iPhone's camera—can be overlaid with useful additional information. Sometimes these types of augmented reality apps use direction and GPS coordinates, or they might recognize 2D barcodes within view of the camera. One concept demonstrated below uses facial recognition to display links to someone's social networking profiles.

Another such augmented reality app is Nearest Subway from developer Acrossair. Using the iPhone 3GS's GPS and compass hardware, the app can overly information about nearby subway stops. Merely by pointing an iPhone in the intended direction, Nearest Subway overlays small signs indicating the next subway stop in that direction, and what lines pass through.

First “Machine Listening” API Flies From The Echo Nest

, , ,

“Machine Listening” is the idea that computers can be programmed to interpret audio signals the same way humans do. This means that they can tell when a song belongs to the blues genre rather than techno. And they can detect musical characteristics like tempos, transition types, and harmonies.

The technology has some obvious practical uses. It could be used to compile collections of music with the same sound or with similarities to the music someone already knows they like. Applications could also be designed to create the perfect mixtapes, with songs picked and ordered in just the right ways.

The Echo Nest is a company that’s bringing machine listening to Web 2.0. It was founded by two MIT PhD students and is supported by a government grant. Today, the company releases the first of several “Musical Brain” APIs intended to improve three main aspects of music-related web services: search, recommendations, and interactivity.
