Abstract

With the Augmented Reality mirror display method using a half-mirror, there is a difference in the focal length between the mirror image and the AR image. Therefore, the observer perceives a mismatch in depth perception, which impairs usability. In this study, we developed an optical-reflection AR display, ALiSE (Augment Layer interweaved Semi-reflecting Existence), which enhances the depth perception experience of AR images by adding a gap zone with the same depth as the target depth between the display and the half-mirror. We conducted an experiment to view 3D objects and achieve virtual fitting using the existing AR with video synthesis and the proposed ALiSE method. As a result of the questionnaire survey, although the comfort of wearing virtual objects was below existing methods, we confirmed that the presence and solidity were superior with the proposed method to other approaches. This is an attempt to create a sense of the stereoscopic effect despite the 2D projection, as the object to be projected is simultaneously reflected in the mirror along with the observer themselves.
