Implementation of Interactive Mirror‐Transcending Aerial Image Display System

ABSTRACT Many methods have been proposed for presenting digital information in mirror space, but existing methods were limited to displaying information confined within the mirror space. Therefore, we propose mirror‐transcending aerial imaging (MiTAI), which allows digital information to move continuously between mirrored and physical spaces. By seamlessly fusing mirror space, physical space, and digital information, MiTAI offers an unprecedented interactive experience. This paper presents a detailed description of the MiTAI system, designed to allow users to experience the concept and facilitate initial studies toward its evaluation. Specifically, we detail the system implementation, including the refinement of the optical system based on previous studies, the control system design, content presentation designs, and interaction methods with the aerial image. Moreover, we report on an experiment evaluating the pointing accuracy in the depth direction of the interaction method and a user evaluation conducted using a refined system setup for a hands‐on demonstration to evaluate the user experience. Finally, we present user feedback from the exhibition and discuss future points for improvement.
