%X Based on perceptual control theory, a task analysis approach is proposed to describe more accurately user tasks in dynamic environments, which is of more powerful and flexible descriptive ability. Theoretically, a task meta model is established to describe the interactive process in an individual, dynamic, and flexible way. Methodologically, an implementation framework is illustrated to map the user-oriented description into implementation-oriented models, which will be as a technical tool to transform from a task model to a user interface prototype.<br>Based on perceptual control theory, a task analysis approach is proposed to describe more accurately user tasks in dynamic environments, which is of more powerful and flexible descriptive ability.
