Screen-based Augmented Reality (AR) systems can be built as a window into the\nreal world as often done in mobile AR applications or using the Magic Mirror\nmetaphor, where users can see themselves with augmented graphics on a large\ndisplay. Such Magic Mirror systems have been used in digital clothing\nenvironments to create virtual dressing rooms, to teach human anatomy, and for\ncollaborative design tasks. The term Magic Mirror implies that the display\nshows the users enantiomorph, i.e. the mirror image, such that the system\nmimics a real-world physical mirror. However, the question arises whether one\nshould design a traditional mirror, or instead display the true mirror image by\nmeans of a non-reversing mirror? This is an intriguing perceptual question, as\nthe image one observes in a mirror is not a real view, as it would be seen by\nan external observer, but a reflection, i.e. a front-to-back reversed image. In\nthis paper, we discuss the perceptual differences between these two mirror\nvisualization concepts and present a first comparative study in the context of\nMagic Mirror anatomy teaching. We investigate the ability of users to identify\nthe correct placement of virtual anatomical structures in our screen-based AR\nsystem for two conditions: a regular mirror and a non-reversing mirror setup.\nThe results of our study indicate that the latter is more suitable for\napplications where previously acquired domain-specific knowledge plays an\nimportant role. The lessons learned open up new research directions in the\nfields of user interfaces and interaction in non-reversing mirror environments\nand could impact the implementation of general screen-based AR systems in other\ndomains.\n
