Eyex calibration on Psychopy

Builder
1

OS: Win 10
PsychoPy version: v2020.1.3

What am I trying to achieve:

I am trying to integrate Tobii Eyex eye-tracker and Psychopy, but the calibration process does not work as expected.

I initialized the experiment with this block of code in “Begin experiment”, like the documentation indicates:

from psychopy.iohub import launchHubServer
from psychopy.core import getTime, wait

iohub_config = {‘eyetracker.hw.tobii.EyeTracker’:

  • {‘name’: ‘tracker’, ‘runtime_settings’: {‘sampling_rate’: 120}}}*

*io = launchHubServer(*iohub_config)

# Get the eye tracker device.
tracker = io.devices.tracker

# run eyetracker calibration
r = tracker.runSetupProcedure()

# Check for and print current eye position every 100 msec.
stime = getTime()
while getTime()-stime < 5.0:

  • print(tracker.getPosition())*
  • wait(0.1)*

tracker.setRecordingState(False)

# Stop the ioHub Server
io.quit()

Unfortunately, does not works. The calibration screen appears but does not offer the calibration process when i press ‘space’ and the stdout was:

Experiment ended.

What did i try to make it work?:

I’ve tried to manage different python versions and different psychopy3 versions, but nothing seems to work
