General considerations:

● Some issues are external to GazeSense. Ensure that your sensor is correctly installed in your operating system, and that it operates properly with the software provided by the respective sensor maker (this software is also installed automatically with the GazeSense installer). Certain sensors require to be connected to a USB 3 port, which is always blue (i.e., these sensors will not work when connected to USB 2 connections of other colors). Always check that the USB plug is properly inserted.
● Bad user calibration will lead to a bad tracking experience.
● People with glasses or with heavily occluded irises might pose difficulties to the eye gaze estimator.
● Significant facial hair could disturb the face tracking.
● Inappropriate illumination could influence the tracking. We recommend testing the setup under controlled lighting conditions, to attain the best experience
● Please avoid using two 3D cameras pointing in the same direction. Their infrared light signals may interfere with each other. In the same sense: please make sure there is no other infrared emitter being used for the same demonstrator, such as a pupil center corneal reflection (PCCR) eye tracking device.


Quick solutions for issues that might arise:
