    Exploring Collaboration with Geospatial Information in Multi-Display Environments
    (2015-05-04) Rodrigues, Francisco Marinho Moreira; Maurer, Frank
    Devices such as tablets and tabletops are now common and widespread, presenting opportunities to explore how these devices can be used in a variety of environments and application domains. Multi-display environments (MDE) incorporate several displays and allow tasks such as information sharing and collaboration amongst users. The geospatial domain affords opportunities to explore collaboration within MDEs, as information can be spread across different geographical layers, scales, and views (e.g. an overview map). This thesis describes the results of a study that investigated how tablets can be used as collaborative tools for geospatial information exploration within MDEs. Participants were divided into pairs within an MDE, and given tasks with differing numbers of tablets and of visualizations per tablet. Results indicated that most users preferred two tablets with all visualizations as ideal for collaboration within the geospatial MDE, and the number of tablets did not significantly impact the completion time of tasks.
