Investigating the Role of an Overview Device in Multi-Device Collaboration

" summary

Voyager multi-device tool lets groups of four (40 participants total) plan a trip using three setups: separate overview tablet (4 groups), integrated inset on personal devices (3 groups), and no overview (3 groups). Empirical results show the separate overview increases face-to-face, closely coupled collaboration, yields more shared opinions and itinerary iterations, helps spot errors and discover route clusters, while the integrated inset fails to boost sharing. Only two groups physically moved the overview tablet, which correlated with more spatial engagement.
