What are you trying to achieve?:
I want to send event markers from the psychopy experiment to the recording stream of our eye tracker (Tobii pro 3).
During the study, the participant is mainly focusing on another person in front of them, the implementation in Psychopy is more of a guidance and time reference (i.e., we are not tracking the eye gaze on screen). What would be handy, though, is:
- starting the recording of the eye tracker with psychopy (to know at which time point in the experiment the recording starts)
- sending markers during different events within a trial (to get even more information what is happening when)
I’m already working with websockets and UDP connection to communicate all this information to our camera system but am a little lost when it comes to the eye tracker as the recording is not done in a software but directly onto an SD card in an extra recording unit device. However, it is possible to connect the recording device to the laptop the experiment is running on with a 3.5 mm jack as sync port.
Does anyone have experinence or information on how to send these instructions (there)? Or is this just not feasible?
Any help greatly appreciated (this is my first time working with eye tracking)!
Cheers, Esther
