Augmented Reality (AR) superimposes computer graphics (CG) onto a user’s view of the real world. A key quality problem in this field is to achieve coherence between reality and CG when the user’s eyes refocus or change pupil size. We designed and evaluated a display that improves coherence by measuring the user’s eye state and continuously adapting CG accordingly. Our tabletop prototype emulates an Optical See-Through Head-Mounted Display, a common AR display device. In our evaluation, participants observed three pillars at different depths. We then challenged them to identify a virtual pillar among the three while freely refocusing their eyes. Results show that our design significantly improved realism. Compared to Light Field Displays, our design aims to simplify display-optics while providing similar quality. We could only partially achieve this goal. We discuss the lessons we learned and how we plan to overcome the remaining challenges. The experimental protocol from our evaluation is useful for display developers as it can be used to measure the coherence of a display. View Full-Text
