Thank you in advance.
PS: If further details are needed, I am happy to provide them.
I have not used these devices myself but one question would be - why does the task need to run in browser as opposed to in the local python version (I ask because PsychoPy has options for interacting with hardware locally but not online, because we see less situations where people want to use hardware remotely)
We need the fEMG information to validate part of the task that does facial emotion recognition via video input (built into the task).
Ah sorry in that case I am afraid I am not familiar with how to send triggers via a web interface, as that isn’t currently supported out of box in psychoJS - I think I want to say “web sockets” (but I am afraid that is all I know!)
