The developer of WordLens, the incredible real-time translation app, has given a short talk about the limitations of augmented reality applications on the iPhone. It’s an interesting interview if you want to get some behind the scenes information.
The main focus of the application is to give a quick-and-dirty translation so tourists can get a general idea of what information signs and other documents are trying to convey. Interestingly, the developer mentions that the text-replacement was the easiest part to program, and the most difficult aspect is identifying individual letters and making due with the low-powered processor and camera. In the future, he plans on making the translations more accurate and speeding up the application.
A full-length video interview is expected in the next few weeks.
