Is That You or The Machine? Translating Sociocultural Norms Across Distributed Spaces in Blended Realities

When distributed mixed reality (MR) systems map physical spaces to enable co-presence of local and remote collaborators, they can unintentionally disrupt the sociocultural norms that give actions their meaning. For instance, a participant sitting at their own desk may be rendered as occupying their collaborator’s desk…

Practice-informed Patterns for Organising Large Groups in Distributed Mixed Reality Collaboration

Collaborating across dissimilar, distributed spaces presents numerous challenges for computer-aided spatial communication. Mixed reality (MR) can blend selected surfaces, allowing collaborators to work in blended f-formations (facing formations), even when their workstations are physically misaligned. Since collaborat…

Blended Whiteboard: Physicality and Reconfigurability in Remote Mixed Reality Collaboration

The whiteboard is essential for collaborative work. To preserve its physicality in remote collaboration, Mixed Reality (MR) can blend real whiteboards across distributed spaces. Going beyond reality, MR can further enable interactions like panning and zooming in a virtually reconfigurable infinite whiteboard. However…

Rapid Prototyping with VideoClipper: In-camera Storyboarding and Video Capture

Although video is extremely useful for expressing interaction, post-hoc editing makes it impractical for rapid prototyping. We present an early-stage video-based design method — “editing-in-the-camera” — where title cards guide video capture and label video clips. This method lets designers easily create video prototy…

Partially Blended Realities: Aligning Dissimilar Spaces for Distributed Mixed Reality Meetings

Mixed Reality allows for distributed meetings where people's local physical spaces are virtually aligned into blended interaction spaces. In many cases, people's physical rooms are dissimilar, making it challenging to design a coherent blended space. We introduce the concept of Partially Blended Realities (PBR) --- us…

Rapido: Prototyping Interactive AR Experiences through Programming by Demonstration

Programming by Demonstration (PbD) is a well-known technique that allows non-programmers to describe interactivity by performing examples of the expected behavior, but it has not been extensively explored for AR. We present Rapido, a novel early-stage prototyping tool to create fully interactive mobile AR prototypes f…

Pronto: Rapid Augmented Reality Video Prototyping Using Sketches and Enaction

Designers have limited tools to prototype AR experiences rapidly. Can lightweight, immediate tools let designers prototype dynamic AR interactions while capturing the nuances of a 3D experience? We interviewed three AR experts and identified several recurring issues in AR design: creating and positioning 3D assets, ha…
