Psychopy and pylink example


I'm working on integrating an experiment in psychopy with the eyelink eyetracking system. The way to do this seems to be through pylink. Unfortunately I'm really unfamiliar with pylink and I was hoping there was a sample of an experiment that combines the two. I haven't been able to find one. If anyone would be able to share an example or point me towards a more accessible manual than the pylink api that sr-research provides I'd be really grateful.

Thanks!


Solution

  • rather than PyLink, you might want to look into using the ioHub system within PsychoPy. This is a more general-purpose eye tracking system that also allows for saving data in a common format (integrated with PsychoPy events), and provides tools for data analysis and visualisation.

    ioHUb is built to be agnostic to the particular eye tracker you are using. You just need to create a configuration file specific to your EyeLink system, and thereafter use the generic functions ioHiv provides for calibration, accessing gaze data in real-time, and so on.
