The process of obtaining design knowledge and user knowledge was applied to capture knowledge of usability.

Based on the user s requests, the users are introduced into the whole process of product conceptual design and the process of user-designer interaction in the computer supported cooperative conceptual design and the expression of user knowledge are discussed in order to enhance the innovation affinity and comfortableness in the stage of product conceptual design.

Three kinds of problems about eliciting user knowledge are discovered through analyzing the test results and the hypothesis of method on eliciting user knowledge based on using products is set up.

It integrates the agent technology of AI, builds specialized knowledge base and user knowledge base.
