I am hanging out at Idee where they are demoing their new iPhone application.

I have to say I am impressed. The application allows you to take a picture of a CD (books and other products coming soon) and the app will then come back with pricing and other information. In the case of a CD, you can sample the tracks and buy them directly from the iTunes store.

After seeing TinEye, a lot of people have asked “what is the killer app for search?”, I really don’t have an answer, because it isn’t really the kind of stuff I think about, but this represents the kind of innovation and interesting applications that can come out of this kind of technology. This might not be the killer app itself, but it shows that there are dozens of problems that Visual Search can solve.

The message I got tonight was that Idee is just getting started in building tools that make use of their core visual search technology, and that we are going to be seeing a lot more in the months and years to come.

This iPhone application should be available within a few weeks, depending on how quickly the iTunes store approves it.

Leila Boujnane, Idee’s CEO, will be speaking at StartupEmpire in November.
