Wrote & tested #MATLAB script to analyze #Tobii eye tracking data for dwell times within specified regions of interest.

Made a few #MATLAB utilities for processing a combined set of eye tracking data from #Tobii and joystick movement data from Neurobehavioral Systems #Presentation.

#Tobii #Python SDK worked fine on desktop PC, but failed on laptop PC. Took an hour or two to figure out that it needed an older version of Python -- desktop ran 3.10.5, laptop ran 3.11.1.

Using modular approach, have #Tobii streaming eye tracking data via #LSL using a #Python program, #Presentation streaming behavioral data via LSL, #LabRecorder gathering & storing the data, and load_xdf.m in #MATLAB to work with the results. Whew! Now I have to integrate this all better.

On to today's challenge -- figure out how to acquire data from #Tobii eye tracker with one process while running experiment task in another process with #Presentation and use Lab Streaming Layer (#LSL) to coordinate both. Sure would help to have a working example to start from!

New project integrating a #Tobii eye tracker with a kinesiology experiment built using Neurobehavioral Systems #Presentation.

Can't help but link to this thread where @Hirstrj adds #Tobii #eyetracking to a #PsychoPy experiment in just 2 minutes 21 seconds for @MarkHaselgrove

legendary skills! 👏
