Pygaze's Area Of Interest (AOI) function equivalent in Psychopy

Coding
1

I’m trying to build a gaze contingent experiment where the trial in a visual search paradigm proceeds to the next when fixated on the target for sometime. I used PyGaze’s AOI function to design the experiment. But the eye tracker (pupil labs) doesn’t support Pygaze and was asked to do the same in psychopy. I’m grateful for suggestions.

PsychoPy has the ShapeStim class for creating geometrical shapes (and has convenience sub-classes like Rect, Circle, etc):

http://www.psychopy.org/api/visual.html

You would define them similarly to the way you do above, by providing coordinates for the vertices. The ShapeStim class has a .contains() function just as in your code above. The shape wouldn’t actually need to be drawn on screen for this function to be used.
