Eye-gaze-triggered Visual Cues to Restore Attention in Educational VR

In educational virtual reality, it is important to deal with problems of student inattention to presented content. We are developing attention-restoring visual cues for display when gaze tracking detects that student focus shifts away from critical objects. These cues include novel aspects and variations of standard cues that performed well in prior work on visual guidance. For the longer term, we propose experiments to compare various cues and their parameters to assess effectiveness and tradeoffs, and to assess the impact of eye tracking. Eye tracking is used to both detect inattention and to control the appearance and location of cues.
