Where To – augmented reality in 3D on the iPhone

Where To? is an iPhone application that implements the APIs for augmented reality in order to provide users with information about points of interest around their location. The application has been available in the AppStore for some time, but recently it was updated and a 3D module was implemented that displays the points of interest in a completely and completely unique way. The application also uses APIs for OpenGL to provide users with the most realistic images of available points of interest.

Our solution: First, results are displayed in a real 3D world and their size and stacking order depends on the distance. Then, you can zoom in and out using the gestures already known from the map: Double-tap to zoom in, two-finger-tap to zoom out, pinch for fine-grained zooming. Zooming of course affects the camera picture as well.

This kind of applications are starting to attract more and more users because they offer the possibility to see all the points of interest around you using the phone's camera. Let's say for example that you are on a street in Bucharest and you are looking for the nearest metro station, well you open the application, point the terminal forward and on the screen you will see points of interest and the location of the place. As you advance, these points of interest will change their position to guide you towards them. There is also such an application for Romania, it also participated in the application contest organized by Orange, but unfortunately it has points of interest only for Bucharest.
