I build this project encouraged for the possibilites of iPad's interaction between software and hardware, as any iOs developer, is exciting to explore the touch handles gestures, but also, the Augmented Reality resources, which we can find on the wide web, are funny enough for even stay a away from the common touch gestures and have fun with the device input cam.

In this project I used a few open source libraries, as the lidpd, a port for iOS SDK of the legendary Puredata libraries, an audio synthesis framework for develop as many virtual audio behaviors as you can imagine. Just with this powerful libraries the audio based applications you could do are fun enough.

But I tried to go beyond. I added a the possibility of control the synthesizer with a printed pattern wich the user can control the pitch of the virtual synth. The libraries used for develop this feature are the Metaio SDK, there are a few Augmented Reality SDKs for work with, with this ones have the possibility to use the front iPad camera, wich was critical for this app.

To be honest, still I find too hard to control the pitch from the webcam, but this project is builded just for fun, and for escape away from the current dull Flash work I use to do for advertising.

So, despite the noisy results I get it, I can say now I really enjoyed to build this application, and also I learn a lots about how works  Augmented reality for mobile devices and the most important for me, is really exciting to spend time in something that is not just for cash.
