Eyelink Toolbox - Known Bugs and Issues
EyelinkDoTrackerSetup function does not display images on display screen
While running an Eyetracking experiment in OS X, you'll notice that performing a tracker setup does not place the camera images on the screen, as it does in OS 9 (or other demos provided by SR-Research).
This is a known shortcoming of the OpenGL EyelinkToolbox. This function/feature has not been implemented in the OpenGL version (yet). It is a bit more complicated to integrate it into the OSX version than it was in the OS9 one. Feel free to have a go at re-implementing this feature ;-).
During calibration, fixations are not accepted automatically
In OS X, the calibration routine does not accept fixations automatically - the spacebar must be pressed to manually accept the fixation, and move onto the next target. Most likely this has to do something with the above mentioned issue that the 'eye-image' is missing during the calibration phase.
Craig Wilson reported this workaround: if you begin calibrating, then press the escape key to re-start, the targets will move automatically once the subject fixates on them.
Eyelink does not report the absence of Eyelink libraries
The EyelinkToolbox will at present issue no warning when the Eyelink libraries/frameworks have not been installed. It will simply do nothing, which may be a bit puzzling for new users. There's no workaround other than to read the installation instructions ;-) We hope to come up with some sort of error report/checking in a future release.
