普适计算使得信息空间与人们生活的物理空间相融合,与此相应人机接口也将随之扩展到人们生活工作的整个三维物理空间.因此需要研究物理空间中的人机交互方式.在传统的计算模式下,交互环境的物理因素不影响人机交互.而在普适计算的模式下,用户和环境的物理因素将成为交互的重要因素,这将使人机交互的性质产生一系列的变化,其中包括:人机交互本质上是与信息空间的交互;交互接口扩展到日常生活的用品和环境;动态的人机交互上下文;蕴含人机交互.
Ubiquitous/Pervasive Computing aims to integrate cyberspace into physical space where people reside. In terms of human computer interaction (HCI), this means to extend the interface of HCI from in the front of computer into whole three dimensional spaces, namely the HCI in Physical Space. Contrasting to the conventional compute mode, where physical factors are not involved in the HCI, under Ubiquitous/Pervasive Computing mode the physical factors about users and environment become the important factors in the interaction. As the results, HCI in physical space will possesses following rational characteristics: (1) the HCI is essentially the inter action with cyberspace, but a single computer; (1)The interfaces of HCI will not rely on the conventional devices such key boards, mouse and monitors, instead they will part of artifacts, furniture, even rooms and buildings; HCI supported by context aware computing will be the Pervasive Computing mode. (3) HCI in dynamic essential part of the integrate or become context; (4) Implicit HCI for Ubiquitous/Pervasive Computing mode.
