| Abstract & Background | Pervasive/Ubiquitous computing is emerging as an exciting new computing paradigm with the objective to provide computations everywhere at any time. It poses great challenge for current human computer interaction model. In this paper, the traditional user-driven interaction framework, in which human computer interaction exclusively depends on user¡¯s explicit input, is theoretically proved to be unsuitable for pervasive computing based on the analysis of characteristics of this new paradigm not only from the level of computing technology, but also user¡¯s cognitive behavior and psychology. Attention allocation of users essentially requires the computing systems to be more active, and the modality conflict needs more natural and flexible facilities. An interaction framework, in which the implicit knowledge extracted from context is seamlessly integrated with the explicit user input from multiple modalities, is then proposed to meet such requirements. It can be also regarded as an interaction design model for pervasive applications. Authors implement this framework in a mobile guide system TGH and evaluate its performance. The results show that this framework improves the naturalness and efficiency of interaction in pervasive computing.
