Collaboration technology and multi-user interfaces

在并置环境中共享显示的交互技术提出了许多挑战。这项提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功能，以确定每种显示器如何最好地支持面对面协作中的特定任务，以及每种显示器如何增强另一种显示器。人们正在研究新的多点触控交互技术和在距离显示器较远的地方使用的技术，特别是在协作环境中，在这种环境中，一个用户与另一个用户的工作流程交互时，必须相互了解彼此的工作流程，以避免干扰和分散注意力。隐私和安全问题出现在特别的合作中，在这种合作中不能假定相互信任。在这些情况下，隐私功能的可用性成为人们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.
