I am an interaction designer and media artist who uses Java and Processing for rapid testing and iteration. My C++-fu is weak.
I’m excited to begin playing.
Thank you for your feature request. I agree, an EyeX Java binding and Processing plugin would be really useful. We have done Java bindings for other API:s and have a guy at Tobii who has built eye-tracking plugins for Processing before, so technically it is definitely possible. It is just a matter of prioritization, so if there is much more demand for it we will push it upwards in the roadmap. Stay tuned!
I preordered two EYEX dev kits and would also welcome a native JAVA API a lot. I never liked C/C++ much and just grew up with JAVA, so that would be the best news possible on this. Thank you
Hello Team Tobii,, I want to work with processing on eye tracking type of stuff using tobii … is their any library they have opencv,, can that library can be work with the Tobbi ir do that have some sort of libraries so in the Processing IDE if I would like to work on Tobii ????
waiting for reply.
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.
I’d also like to have a Java API, or at least an OpenFrameworks plugin. I’d prefer Java though. I’ve never created a JNI binding to a C API, but maybe I’ll try it whet my unit arrives.
Still nothing new on this? I have my dev kit since a few weeks not and cant really do anything with it. I counted on that there would be a Java API/SDK too.
Hi Marc,
it’s clear that we will have to do something about that Java support 😉But, like Robert wrote, there are many things in the works. So please bear with us.
Hi,
FYI: As recommended before, it is possible to bind the native methods to java using JNI.
I successfully implemented an interface for using the eyetrackers coordinates. Maybe I can share the code, but I have to check if I am allowed to first (copyright). Perhaps for now a short guide is of interest:
1) Create a java class with the native methods: One for each coordinate (=4) and one to start the tracking and if needed, one to stop it.
2) Generate the header file (e.g. using javah)
3) Create your c/c++ – code:
For me, the MinimalTracker sample was helpful. To start and stop the tracking, the main()-method provides all needed information. Note that xsleep will not work in jvm. The coordinates can be passed to the JNIExport-Methods.
4) Build it as .dll
5) include the .dll and the TobiiGazeCore__.dll in your java project.Greetings
my tobii eyex controller arrived yesterday. i’m also struggling to implement it in openframeworks or processing. does anyone have a solution for openframeworks? – think its easier to build a bridge because it’s c++
