User perspectives on mixed reality tabletop visualization for face-to-face collaborative design review

Mixed Reality (MR) technologies create an environment where virtual objects and real objects can be presented together on a single display. An MR-based face-to-face design review prototype was created for the purpose of improving design review collaboration. The work presented in this paper investigated how users experienced virtual models in the MR system and assessed the users' experience and attitude towards the effectiveness of the MR tool for design review as compared with a 3D paper-based method. The findings from user feedback suggest that the MR tool may facilitate problem-solving and the quantity of work in a given amount of time and that virtual design displayed in the mixed scene was a useful aid in the design error detection task. Experimental usability evaluation of the MR system was also implemented and suggestions for improvements of the human–computer interface of future system versions were produced.
