The ubiquitous computing vision includes Single Display Groupware (SDG) devices embedded in our normal envi- ronment. This paper explores the nature of interfaces for supporting people in accessing their files on such displays. To do this, we designed a study comparing people’s interac- tion with two very different classes of tabletop file system access interface: Focus explicitly designed for tabletops and the familiar hierarchical Windows Explorer. We designed a within-subjects double-crossover study where participants collaboratively completed 4 planning tasks. Based on video, logs, questionnaires and interviews, we conclude that both the classes of interface have a place. Notably, Focus con- tributed to improved collaboration and better use of the in- terface. Our results inform a set of recommendations for future interfaces for this important class of interaction, sup- porting access to files for collaboration at tabletop devices embedded in the environment.
