Webgazer Can I pause the current trial to check if the user’s eyes are still on the screen?

[ljhtx]

I want to pause the current trial during the experiment if the user’s eyes are detected to be off the screen, and then resume the trial once the user returns and passes the detection(such as showVideo()).

pauseExperiment will end the current trial. I’d like to know if there’s another way to simply pause without ending the trial?
