Abstract
Studies on collaborative virtual environments (CVEs) have suggested capture and later replay of multimodal interactions (e.g., speech, body language, and scene manipulations), which we refer to as multimodal recordings, as an effective medium for time-distributed collaborators to discuss and review 3D content in an immersive, expressive, and asynchronous way. However, there exist gaps of empirical knowledge in understanding how this multimodal asynchronous VR collaboration (MAVRC) context impacts social behaviors in mediated-communication, workspace awareness in cooperative work, and user requirements for authoring and consuming multimedia recording. This study aims to address these gaps by conceptualizing MAVRC as a type of CSCW and by understanding the challenges and design considerations of MAVRC systems. To this end, we conducted an exploratory need-finding study where participants (N = 15) used an experimental MAVRC system to complete a representative spatial task in an asynchronously collaborative setting, involving both consumption and production of multimodal recordings. Qualitative analysis of interview and observation data from the study revealed unique, core design challenges of MAVRC in: (1) coordinating proxemic behaviors between asynchronous collaborators, (2) providing traceability and change awareness across different versions of 3D scenes, (3) accommodating viewpoint control to maintain workspace awareness, and (4) supporting navigation and editing of multimodal recordings. We discuss design implications, ideate on potential design solutions, and conclude the paper with a set of design recommendations for MAVRC systems.

Challenges and Design Considerations for Multimodal Asynchronous Collaboration in VR
Recommendations
Constructing a web-based asynchronous and synchronous collaboration environment using WebDAV and Lotus Sametime
SIGUCCS '01: Proceedings of the 29th annual ACM SIGUCCS conference on User servicesIn this paper we present our practice of constructing a Web-based asynchronous and synchronous collaboration environment for supporting collaborative distance learning between a German university and a university in Italy. We utilize the recent ...
Asynchronous industrial collaboration: How virtual reality and virtual tools aid the process of maintenance method development and documentation creation
AbstractIn the light of Industry 4.0, the field of Industrial Maintenance faces a large digital transformation, adopting Extended Reality (XR) technologies to aid industrial operations. For the manufacturing corporations that provide ...
Highlights- This study provides qualitative insight on how VR is used to aid maintenance method and technical documentation creation.
Distributed pointing for multimodal collaboration over sketched diagrams
ICMI '05: Proceedings of the 7th international conference on Multimodal interfacesA problem faced by groups that are not co-located but need to collaborate on a common task is the reduced access to the rich multimodal communicative context that they would have access to if they were collaborating face-to-face. Collaboration support ...
