Focused augmented mirror based on human visual perception

A mirror is used in various aspects of daily life; thus, most people can use a mirror-metaphor augmented reality (AR) system naturally, without wearing a head-mounted display or AR glasses. An augmented mirror, one of the mirror metaphor AR display, is considered a more appropriate system than video-based virtual mirror display for personalized and immersive interaction in AR because it can show a combined scene in which a rendered virtual world is superimposed on the reflected real world based the viewpoint of a user. In this paper, we propose a focused augmented mirror that implements both viewpoint and depth-of-field matchings. In particular, we design a focused augmented mirror by concentrating on how the depth-of-field influences human visual perception in the augmented mirror system. To compare the differences between the theoretical and practical results, we perform two types of experiments; calculating the focus measure of the combined image photographed at user’s viewpoint and evaluating user experience with randomly selected non-expert people. In addition, we suggest an efficient user workspace that is limited by the tracker’s geometric configuration and the target object’s depth of field. Finally, we describe the physical limitation of our system and propose its solution as a future work.
