UOUU: User-Object Distance and User-User Distance Combined Method for Collaboration Task

Augmented reality superimposes digital information onto objects in the physical world and enables multi-user collaboration. Despite that previous proxemic interaction research has explored many applications of user-object distance user-user an augmented context, respectively, combining both types can improve efficiency users’ perception with task collaborators by providing users insight into spatial relations user-task object user-user, less is concerned about how two distances be simultaneously adopted to assist collaboration tasks across multi-users. To fulfill gap, we present UOUU, combined method for dynamically assigning users. We conducted empirical studies investigate affected user terms occurrence overall efficiency. The results show significantly improves speed accuracy as well frequencies occurrences. study also confirms method’s effects on stimulating activities, UOUU effectively reduced participants’ perceived workload moving during tasks. Implications generalising use are discussed.
