Re: [osg-users] Open source projects for eye tracking
I asked Oleg Komogortsev, an eye-tracking researcher at Texas State University: here is what we use at the moment http://www.gazegroup.org/ , the quality of the results will depend on your camera hardware. But this is the best in my opinion at the moment. I briefly looked it up, and their GPL software is based on http://sourceforge.net/projects/gazetrackinglib/, which in turn is based on openCV (via emguCV .NET bindings unfortunately). However, it might provide useful pointers for new projects.

A quick search of the web suggests that there are solutions out there, including some open source ones, but as to how good they or how suitable they are for use in a cross platform C++ app (that will built on top of the OSG) I can't say without doing lots of download, building and testing. Now there is quite a bit of VR expertise in this community, a pretty decent place to asks for thoughts on best VR related technologies, so... what do you guys think about this topic? Are there good open source eye tracking libs out there that are easy to use and integrate?

Re: [osg-users] Open source projects for eye tracking
It's fairly easy to do in OpenCV using Haar trackers. OpenCV also handles all the webcam stuff for you fairly painlessly. See http://www.codeproject.com/KB/cpp/TrackEye.aspx for example. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=15968#15968 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Open source projects for eye tracking
Sorry forgot to add, OpenCV is C/C++, cross platfom is BSD licensed and works well with OSG. The documentation isn't bad and it's used by a lot of vision courses so quite a few tutorials out there. There is a good intro book from O'Reilly Martin -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=15971#15971 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Open source projects for eye tracking
Hi Martin, Thanks for the pointer. Have you use TrackEye yourself? Robert.

Re: [osg-users] Open source projects for eye tracking
No, other than running the demo. I once did something to automatically find pupil position/size for an opthalmic system but it didn't do gaze direction. One thing that was very useful (if you can control the environment) was to use an IR LED which reflects off the cornea and an IR sensitive camera to find the eye. For the opthalmic app we couldn't have bright lighting. The openCV code is reasonably good but the community and forums aren't as helpfull as OSG. There are a lot of how make seeing robot newbie posts. For some reason openCV is very popular in India/China.
