TUIO for Android
In March 2011, I wrote a TUIO service for Android. This enables anyone using the TUIO Protocol to control an Android OS. The applications for this are wide-ranging. I have plans to incorperate it into the Android X86 Project, as well as present it at conferences.
Techincally, TUIO for Android works by exploiting several hidden API features in the OS. From there, we can extend upon several base classes to add new functionality. On top of that, our service can also run any java gesture interface to detect gestures, and fire corrisponding events using the same mechanisms.
TUIO for Android was used in http://blog.recursivepenguin.com/?p=70, which was featured on Gizmodo, Make, Phandroid, and more.
