Collaboration technology and multi-user interfaces

在并置环境中用于共享显示器的交互技术提出了许多挑战。这项拟议的研究考察了桌面显示器、大型壁挂式显示器和手持显示器的负担能力，以确定在面对面协作期间，每种显示器如何最好地支持特定任务，以及每种显示器如何增强对方。正在进行对新颖的多点触摸交互技术和在远离显示器时使用的技术的调查，特别是在协作环境中，其中必须权衡彼此的工作流的相互意识，以防止一个用户与另一个用户的工作流交互造成的干扰和分心。隐私和安全问题出现在临时协作中，其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一个重要问题。

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.
