Abstract We propose an MR “domino toppling” attraction as a case study of MR 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 pushes 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 implemented simple switching devices. In addition, we use diminished reality techniques to visually remove the devices to make it harder for the user to distinguish R–V/V–R transitions.
