How to log mouse responses during pygaze recording?
I just started using Open Sesame (thanks Sebastiaan and team!) after doing the visual world tutorial online. Unfortunately, I ran into a problem when trying to adapt the tutorial to my own experiment.
The structure of my trial is: participants are presented with 4 objects jointly with a spoken instruction (e.g., "Click on the apple"), while their eye-movements are recorded. I need the trial to end when participants click on one of the 4 objects.
I have added a mouse_response item after the visual_display and the spoken instruction. However, I can't set 'mouseclick' as the argument of Duration in the trial_coroutines item: OS yields an error saying that 'end' needs to be non-negative and larger than 'start' (this is why Duration is set to 7000 in the screenshot below). And when I run my experiment, clicking doesn't do anything and the spatial coordinates of the click are not logged. I would really like to log on which of the 4 objects participants clicked, as well as the timestamp of the click: is this possible to do in OS?
Any ideas on what I am doing wrong?
Thanks a bunch!
