TY - THES A1 - Schaffer, Josefa T1 - Precision in eye tracking: evaluation and improvement of accuracy N2 - This thesis will evaluate the accuracy of the Tobii Pro Glasses 3, which are wearable eye tracking glasses. A static and dynamic accuracy study will be conducted, utilising a poster and imitating realistic environments. The results will be evaluated using a self-developed sample-wise approach, trying to determine possible differences between static and dynamic conditions while wearing eye tracking glasses. In addition to that, a tool named glassesValidator, used to calculate data quality metrics of eye tracking glasses, will be evaluated on its accuracy and validity itself. In the static accuracy study, participants will focus, in reading order, on nine fixation targets on the poster for at least two seconds while using a chin rest to prevent head movement. In the dynamic accuracy study participants will be walking in a semicircular movement around the poster while focusing only on the central fixation target on the poster. The results for the static and dynamic study will be compared to each other, providing possible influence of different lighting conditions and the usage of contact lenses. The results provided by glassesValidator and the self-developed accuracy approach will also be compared to each other to evaluate and provide possible improvements to increase the accuracy of the tool.
