I see. Because of the very nature of PCIbex, hardware communication seems complicated, at best, so the most promising implementation I see would still need to use URLs.
In any case, as you said, I don’t think PennController would be the right tool to collect this kind of data, in this kind of setup. Not only is it ill-designed for wired communication, it’s also javascript-based, which means a time resolution of tens of milliseconds at best.
I’m also curious as to how you measure an increase in skin conductance in an online setting: do you specifically recruit participants who have access to a machine that can collect this sort of physiological data? Are they students in a program?
