Hi there, figured this was more of a jspsych issue than a webgazer issue seeing as I'm working with the webgazer-validate plugin. When running through a generic camera calibration, I run in to trouble pretty quickly after the
jsPsychWebgazerCalibrateCamera
plugin instantiation. I can successfully complete around 30 second of the calibration before this error is thrown:Tracked down the error to the aforementioned
plugin-webgazer-validate
that's imported (the current version published through npm). The troublesome function as follows:Best guess here is that
gazeData
is never correctly populated, socalculateSampleRate
always returns null. I don't know enough about how webgazer functions internally to diagnose the problem. I'm running the experiment in browser with all my dependencies imported through npm. I was curious to know if anyone had run into a similar issue and had some wisdom to share. I am of course happy to provide any more specific information that may provide a clearer picture. Copied below is the timeline I export for the calibration:Beta Was this translation helpful? Give feedback.
