Abstract: To coordinate information requirements and resource operations in human-computer interaction, with the analysis of both internal and external visual representations in cognition process, a new resource model based on distributed cognition was proposed. Information resource was defined and organized by information structures in this model, the resource application process was configured by interaction strategies, and modeling methods as well as implementation strategies were described by intelligent Agents. The exterior cognition and apparent cognition were realized to reduce user′s cognition load in human-computer interaction through interaction process and user interface design. An instance of computer-aided cell phone keyboard color design prototype was provided to illustrate the feasibility and effectiveness of the proposed model.

Key words: human-computer interaction, distributed cognition, resource model, information structure, interaction strategy, intelligent Agent, computer aided design
