Recording webcam feed of respondent during stimulus presentation.
I am designing an experiment where the respondent will be shown some textual questions on the screen and they need to answer it using the keyboard. I want to record their eye movements during this process for which I am using the EyeLink 1000 Plus eye tracker. I also have a Logitech Webcam which I wan to use to record the respondent's face. How do I go about with the webcam recording?
