People tend to move their eyes towards the objects of their interest. However, when they are asked to pay attention to several objects at once, it is not clear how they are optimizing their eye movements with respect to the positions of the objects and the distances to the other objects within the scene (distractors).
In a typical Multiple Object Tracking experiment a person watches a screen with 8 identical dots. Four dots are highlighted for 2 seconds, and then they turn gray and all dots start to move for 10 seconds. Finally, the motion stops and the person is asked to identify the previously highlighted dots. The task has been used for many experiments on spatial attention in psychology, but in combination with computer-based eye tracking it provides also an interesting challenge for computer scientists. Only few studies so far attempted to model eye movements in this dynamic task, while there are several models designed for static attentional tasks (e.g. visual search).
Goal of the project is to design one or several models of eye movements during Multiple Object Tracking, based on the empirical data and literature. For this purpose it will be necessary to design, implement and evaluate an eye tracking experiment. The eye movement predictions of the proposed model/s will be evaluated in a subsequent experiment, and the performance will be compared with other models.
