Collaboration technology and multi-user interfaces

用于并置环境中的共享显示器的交互技术提出了许多挑战。拟议中的研究检查了桌面，大型壁挂式和手持式显示器的功能，以确定每个显示器如何在面对面协作期间最好地支持特定任务，以及每个显示器如何增强其他显示器。正在进行对新颖的多点触摸交互技术和在距显示器一定距离处使用的技术的研究，特别是在协作环境中，其中必须权衡对彼此的工作流的相互意识与一个用户与另一个用户的工作流的交互的干扰和分心。隐私和安全问题出现在临时协作中，在这种协作中，不能假设相互信任。在这些情况下，隐私功能的可用性成为正在研究的重要问题。

Interaction techniques for shared displays in collocated environments present a number of challenges. The proposed research examines the affordances of tabletop, large wall-mounted, and hand-held displays to determine how each best supports specific tasks during face-to-face collaboration, and how each can augment the other. Investigations of novel multi-touch interaction techniques and techniques for use at a distance from the display are being conducted, especially in collaborative environments where mutual awareness of each other's workflow must be traded off against interference and distraction by one user's interaction with another's workflow. Privacy and security issues arise in ad hoc collaborations, where mutual trust cannot be assumed. In these situations the usability of privacy features becomes an important concern that is being studied.
