- Eye movements reflect the cognitive advantage of experts over novices in a domain specific task. Current literature focuses on fixations but leaves out saccades. This research investigates the gaze behavior of dentistry students and expert dentists viewing orthopantomograms (OPTs). All proposed Long Short-Term Memory (LSTM) models were able to distinguish expert and novice gaze behavior by saccade features above guess chance, with the best performing feature having an accuracy of 77.1%. The results provide further evidence for the holistic model of image perception, which proposes that experts initially analyze an image globally, and then proceed with a focal analysis. Further, our results show that saccade features are important to understand expert gaze behavior, and therefore should get integrated into current theories on expertise.
- Alfred L. Yarbus investigated eye movement patterns in the 1960s and discovered that top-down contextual clues affect our gaze behavior. With further development of Bailey’s subtle gaze direction method, we investigated whether gaze behavior can be manipulated using adaptive gaze guidance. Trough manipulating salient, visual features in an image, gaze can be guided. Although we did not succeed in significantly manipulating gaze behavior, we developed a stable software for manipulating gaze online. Considering our suggested improvements, it may be possible to manipulate the gaze behavior with adaptive gaze guidance to a certain extent.
- The propaganda images used during the active time of the Nationalsozialistische Deutsche Arbeiterpartei (NSDAP), were one of the most influential images used to promote a certain ideology. In modern times these images seem outdated. However, do these propaganda images still influence our perception of Adolf Hitler and his ideology? Using eye tracking, we analyzed the attention distribution of people touching these pictures to find influences of the “near-hand phenomenon”, which explains a more sympathetic affect towards people we touch. It was found that the near-hand viewing condition leads to lower viewing duration and higher number of fixations, indicating a tendency to devote more attention to the images when touching them than compared to the control group.
