Eye tracker advanced dummy mode (mouse simulation) not working

Paula

Hi!

I am using Open Sesame 3.2.8, and the advanced dummy mode does not work at all. It would be really useful to have it working, as I have limited time with the eyetracker.

I tried it in different backends and I get the same result. I even tried it with the eyetracking template from OS: the experiment works as expected (I get no error message) but it completely ignores the mouse simulation. Any idea why this would be so?

Thanks,

Paula

Hi Paula,

What happens exactly? That is, in what sense is the mouse simulation ignored?

Cheers,

Hi Sebastiaan,

It is ignored in the sense that it does not appear at all: there is no calibration at all, and the experiment starts immediately...

Thanks,

Paula

Hi Paula,

Right, I see! The mouse doesn't need to be calibrated, so that's why the calibration (which is device-specific) is ignored. However, the simulation will give you simulated gaze position, etc. So for example if you use a pygaze_wait item to wait for a saccade start, then that should work with the mouse.

Cheers!

Hi Sebstiaan,

Thank you for the explanation! I was expecting to be able to "do" the calibration with the mouse, using the mouse arrow as the gaze. That would have been helpful for adjusting the child-friendly calibration off-site.

Thanks again for the clarification.
