ARCritique: Supporting Remote Design Critique of Physical Artifacts through Collaborative Augmented Reality

Critique sessions are an essential educational activity at the center of many design disciplines, especially those involving the creation of physical mockups. Conventional approaches often require the students and the instructor to be in the same space to jointly view and discuss physical artifacts. However, in remote learning contexts, available tools (such as videoconferencing) are insufficient due to ineffective, inefficient spatial referencing. This paper presents ARCritique, a mobile Augmented Reality application that allows users to 1) scan physical artifacts, generate corresponding 3D models, and share them with distant instructors; 2) view the model simultaneously in a synchronized virtual environment with remote collaborators; and 3) point to and draw on the model synchronously to aid communication. We evaluated ARCritique with seven Industrial Design students and three faculty to use the app in a remote critique setting. The results suggest that direct support for spatial communication improves collaborative experiences.
