Cross-Device and Multi-Display Interfaces for supporting Group Work
Cross-device environments(XDEs) have been developed to support a multitude of collaborative activities.Yet, little is known about how different cross-device interaction techniques impact group collaboration; including their impact on independent and joint work that often occur during group work. In this project, we explore the impact of two XDE data browsing techniques:TOUCH and TILT. Through a mixed-methods study of a collaborative sensemaking task, we show that TOUCH and TILT have distinct impacts on how group accomplish, and shift between,independent and joint work. Finally, we reflect on these findings and how they can more generally inform the design of XDEs.
Meanwhile, Multi-Display interfaces provide people with both personal and shared workspaces to support various independent and collective tasks during group activities, exploring how existing interaction methods for cross‐device transfer, such as the Pick‐and‐Drop (P&D) method, can be adapted to table‐centric multi-surface environment settings. The study examined the use of device‐specific visual feedback to improve users' awareness of transferred content during P&D transfer.
