多显示表面环境的多用户交互模型

Multi-user interaction model in a multi-display environment

多显示表面环境为同地协同工作的用户提供视觉为主的共享通道,对其建模是建立同类系统的参考和提高交互效率的基础。该文提出了该环境中的多用户交互模型,规范定义了用户、显示表面、交互接口、应用程序等组成元素的功能和属性,定义了交互管理策略及消息形式。参考该模型,该文设计实现了WeSpace系统,并通过实际应用证明WeSpace可有效促进天体物理学家的现场合作交流,验证了模型架构和策略对构建具有异构、动态、并发、共享等特性的自然交互系统具有指导作用。

Multi-display environment,which provides shared visual output,is a typical setting for co-located collaborative activities.This paper proposes a model to support multi-user interactions in a multi-display environment.The model is composed of modules with definitive functionalities and attributes, with the interaction management procedures and the messages passing through formulated.Based on the model,this paper also implements a multi-user system,named WeSpace, which effectively supports astrophysicists＇daily practice and verifies the model＇s advisory influence on building future systems with heterogeneous and dynamic device settings and shared and parallel interaction styles.
