In this paper, we present an MR-based attraction, “DOMINO (DO MIxed-reality NOn-stop) Toppling,” as a case study of MR-based entertainment systems, focusing on the Real-Virtual (R-V) and Virtual-Real (V-R) continuum. In this attraction, the user experiences that real and virtual domino blocks seamlessly push each other through a video-seethrough head-mounted display. Therefore, the user may believe that attractive MR effects happen in the real space. To achieve the seamless R-V/V-R transitions, we designed and implemented simple switching devices. We carried out demonstrations of our system at an international symposium and found such seamless R-V/V-R transitions effectively entertained people.
