交互技术的发展推动着交互方式的转变并催生新的交互理论和交互范式。隐式人机交互是一种新型人机交互范式，其特点是用户无需直接操作计算机等设备，交互系统通过分布式传感器检测，分析用户动作，在线地获取当前的动态上下文，用于理解用户的意图，作为系统的隐含输入，产生与用户意图相适应的隐含输出来为用户服务。本文分析了隐式交互对计算系统的需求，提出了通用化的面向应用的服务共享模型，以用于构建分布式视觉系统。基于该系统实现的隐式交互实例表明，上述模型是通用的服务共享模型，能够实现多种隐式交互系统。

The development of interaction technologies is advancing new interaction models and theories. Implicit human computer interaction is a new interaction paradigm, which models a new interaction pattern that people is served without manipulating the interaction devices. The interaction system serves to people based on the understanding of their intention by analyzing the behavior and being aware of context in real time. Based on the analysis of the requirements of implicit interaction, this paper proposed a generalized application oriented service share model (AOSSM) for constructing distributed vision system to support implicit interactions. Two implicit interaction systems on group interaction and ambient kitchen are implemented, which demonstrated the effectiveness and the generalization of AOSSM.
