Calibration module does not work using eyetribe

[JanKoopman]

Dear Edwin,

I'm trying to work with teh eyetribe and pygaze. Mainly it's calibration mode.
When running the current code:

from pygaze import libscreen
from pygaze.libscreen import Display
from pygaze import eyetracker
#import pygaze       
import scipy 

display = libscreen.Display()
eyetracker = `eyetracker.EyeTracker(display)
#eyetracker.TRACKERTYPE = "eyetribe"
eyetracker.calibrate()

Once, what appears to be the calibration module, I'm asked to return a space, a q or a s. None of the entries seem to work. I don't get an error, only the warnings. Any idea what I should do differently?

C:\Python27\lib\site-packages\psychopy\visual\helpers.py:176: FutureWarning: comparison to None will result in an elementwise object comparison in the future.
if color==None:
C:\Python27\lib\site-packages\psychopy\visual\basevisual.py:943: FutureWarning: comparison to None will result in an elementwise object comparison in the future.
if value == None:

Hi Jan,

Thanks for the question. Would you mind trying the following code? (I assume you have the latest version of PyGaze installed, as downloaded from this GitHub page.)

from pygaze.display import Display
from pygaze.eyetracker import EyeTracker

disp = Display()
tracker = EyeTracker(disp, trackertype='eyetribe')

tracker.calibrate()

tracker.close()
disp.close()

Your example contains syntax errors, and I can't see what you set the tracker's type to. So this is just to confirm that you are actually using the EyeTribe.

Cheers,
Edwin

Hallo Edwin,
Thanks for your response. I'm afraid I don't completely understand your
question.
I attached the "defaults.py" routine to be sure
I coppied your syntax, but there is no difference.
When I kill the programm using CTRL-ALT-DELI see it is stuck in the
PsychoPy module

Kind regards,
Jan
