I have successfully gotten blob angle data in my app using TUIO 1.1 from CCV but I only seem to be getting an angle from 0-90 degrees. Is there an issue with the tracking or something I have to do in the settings to get a correct angle? As I rotate my finger the angle jumps back to 0 every 90 degrees.

Any help would be much appreciated!

Thanks.

Depends upon how are you calculating the angle , angle of the bounding box ?

I am trying to get the angle of the bounding box or the ‘a’ value according to the TUIO 1.1 spec. (to orient an object on the screen to my finger).

At the moment I am just putting together a TUIO debug app for a client to test on their system using TuioAs3 (bubblebird.at/tuioflash/tuio-as3-library/‎). I am not sure whether this library is doing something with the angle data when it receives it since the spec says that value should be from 0-2PI. I will do a bit of digging in the library to see if it is altering the value.
