Abstract
The issues of Human–Machine Interface (HMI) of Virtual Environment (VE) are discussed in view of users' potential application requirements in VE. The Human-centered HMI containing rich context information is proposed by taking the advantage of the abundant research findings of artificial intelligence and pervasive computing. The technology of context-aware computing is introduced in this study for providing initiative services mode as well. First, in view of the characteristics of VE, the Web Ontology Language (OWL) is adopted to model the context information. Second, the modified ID3 decision-tree algorithm is applied to automatically generate the context rules of VE. Third, the polymorphic proactive services model based on context rules is designed. Finally, an example is given to illustrate how to apply context rule-inference to realize proactive services. The experiment demonstrates the correctness and effectiveness of the above mentioned algorithm and model.
