面向多显示环境的分布式用户界面研究

Multi-Display Environments (MDE) is a kind of virtual workspace composed by several display devices connected together in the same place. In MDE, users can gain information from different displayers with multiple sizes and shapes and users can interact with the virtual workspace via various interactive modesto achieve the ultimate aim of local collaboration. The current research will study problems related to distributed user interface in MDE. Firstly, we will explore the user interactive features and propose the distributed user interface model in MDE. Secondly, we will study the problem of interface inconsistency in Cross-Device Interaction and present Multi-Display interactive mechanism and distributed user interface description. Then we will solve the problem of process inconsistency in Cross-Device Interaction and design interaction techniques that support interoperation among multiple displayers. Finally, we will construct an environment with visual analysis of multi-display information through integrating large screen display and personal mobile devices. All the models, methods and technologies proposed in this study will be sufficiently validated and evaluated. Multi-Display Environments (MDE) has unique advantages in exploring, understanding, exploiting and operating heterogeneous multi-source information in a wide range of applications. The study of MDE will provide a high-available working environment for collaborative design, emergency incident response, comprehensive information visualization, city planning and information visualization and analysis etc.. The study has significant meanings both in theoretical investigation and practical application.

多显示环境(MDE)是由处于同一物理位置的多个相互连接的显示设备组成的虚拟工作空间。在MDE中,用户可以从不同尺寸和形态配置的显示器上获取信息，并通过多种交互手段与虚拟工作空间进行交互，进而实现本地协同工作。本课题研究面向多显示环境的分布式用户界面问题，主要包括：研究多显示环境下用户交互特征，提出面向多显示环境的分布式用户界面模型；研究跨设备交互界面一致性问题，提出多显示交互机制和分布式用户界面描述方法；研究跨设备交互过程一致性问题，设计支持多显示器内容互操作的交互技术；构建以大屏幕显示为核心，集成个人和移动计算设备的多显示信息可视分析环境，对所提模型、方法和技术进行验证和评估。多显示环境对探索、理解、利用和操作来自多源的异质信息类应用具有其独特的优势，研究的开展将为诸如协同设计、应急事件响应、综合信息可视化、城市规划、信息可视化和分析等提供高可用的工作环境，具有重要的理论价值和应用意义。
