Workshop on Interaction on Large Displays (In conjunction with ITS 2015)
Eye Tracking has been successfully applied in Human-Computer Interaction, be it as input mechanism or as measurement of quality e.g. for immersion. In order to validate the quality of interaction modalities of a system, questionnaires or performance metrics e.g. task completion time can be used but these approaches only evaluate the overall quality of a system. Our experiment show that the mean Pupil Dilation increases upon performing a specific interaction technique with a public display ensemble, even more when an interaction does not lead towards the expected outcome ? e.g. fails to perform the intended action. In turn, we have established a connection between Pupil Dilation, Interaction Technique and User Reported Effort Ratings in our experiment with a public display ensemble.
