Here’s an update from Tobii. We want to make a Java binding, but right now we have many other cool things in the pipeline and have not been able to prioritize Java support for a while. If you want to start working with Java we recommend to use JNI or Swig to create your own binding towards the C API. If one of you has already created a Java binding or Processing plugin, you are very welcome to share it with the rest of the community.
