Hi,
I’m using the tobii-spectrum eyetracker. When using the eyetracker with the Psychopy wrapper not all possible data is saved. It looks like the data saved includes:
- gaze position on the monitor
- pupil diameter
- normalized coordinates (track box coordinate system)
However, the eyetracker returns more data than this. It would be nice to have xyz gaze origin and gaze position as well (user coordinate system). From this you’d be able to get distance from monitor (more accurately and varying over time), visual angle and gaze vector (participant looking at screen from a given angle). Would it be possible to add these? Below are links about these different coordinate systems and data types.
Thanks for making this really nice wrapper for the eyetracker. It really made it easier to start using it.
