During an eye tracking session, the movement of the head is one of the factors that may have an impact on the gaze data accuracy. In this page we will discuss how robust Tobii Eye Trackers are to head movement.
Blinking is most often an involuntary act of shutting and opening the eyelid. In this page we will look at the consequences of blinking on your eye tracking data.
The Tobii Pro Glasses 2 system is primarily designed for use in dry indoor environments. Depending on the level of sunlight Glasses 2 will function in outdoor environments as well. Make sure that the Glasses are not exposed to direct sunlight since that might affect eye tracking results negatively. Further make sure that the Glasses are protected from water or moisture since that might harm the unit. For more info please read chapter 1.1.11 of the Tobii Pro Glasses 2 Manual.
The IR light from the eye-tracking illuminators is invisible to the eye, but sometimes visible to digital cameras. Digital cameras often use infrared blockers, but cheaper digital cameras and camera phones have less effective filters and can 'see' intense near-infrared, appearing as a bright purple-white color.
