We introduce SPARC, a new approach to shared perspective in multi-user collaboration. Each user has a first-person view of the workspace while seeing the others’ avatars at their positions around the workspace. Whenever a user manipulates an object, others will see his/her arms stretching to reach that object in their first-person perspective. SPARC combines a shared orientation and support to nonverbal communication, minimizing occlusions. We conducted a user study (n=18) to understand how the novel approach impacts task performance and workspace awareness. We found evidence that SPARC is more efficient and less mentally demanding than life-like settings.

摘要

We introduce SPARC, a new approach to shared perspective in multi-user collaboration. Each user has a first-person view of the workspace while seeing the others’ avatars at their positions around the workspace. Whenever a user manipulates an object, others will see his/her arms stretching to reach that object in their first-person perspective. SPARC combines a shared orientation and support to nonverbal communication, minimizing occlusions. We conducted a user study (n=18) to understand how the novel approach impacts task performance and workspace awareness. We found evidence that SPARC is more efficient and less mentally demanding than life-like settings.
