the eyetracker calibration is not working
- First of all, check if the eyetracker produces a correct signal:
- Video eyetracker:
- Is the image of good quality?
- Is the eyetracker software able to fit the pupil correctly?
- Do you see an eye position trace for all relevant gaze directions?
- Video eyetracker:
- Is the voltage of the adjusted eye, produced by the eyetracker, connected to the eye X/Y connectors of the nrec data acquisition box?
- Is nrec getting any valid data? Try to activate "raw data" below the eye position panel to display the acquired voltages.
Did you select the menu entry nrec - reset calibration before starting the calibration experiment?
