Abstract: In this study,two command information systems are compared in a case study to establish a systematic method for user research.Based on the concept of“user centered design”,users,designers,experts and operators were surveyed using methods such as in-depth interview,analytic hierarchy process,semantic evaluation,emotional evaluation,physiological and psychological evaluation,operational behavior statistics.Finally,this study established a systematic method for user research in human-computer interaction design for command information system.The application of a systematic user research method can improve the user experience of human-computer interaction.
