In the design of human-computer interface, traditional task analysis and use models from GOMS method cannot meet the requirements of the application environment. Recently, a lot of researchers propose activity theory to support foundation of human-computer interaction (HCI). It describes motives, actions, and operation sequences for human interacting with computers. Even the relationships within community, peripheral environment, and sociological factors have been implied. This study applies activity theory to develop HCI of WebTV. First, a deep interview based on activity theory is implemented. Then, from the results of interview, I capture three models of interaction: information retrieval, information sharing, and information processing models. Through these models, I define the functions of information retrieval, share, and process to support human activities. Finally, I construct scenario of using WebTV to show the effects from community of activity theory and scenario can apply to test and evaluate system usability. This study also proposes a new design process of HCI. With study of Yu(1999), from the method based on activity theory for analysis of HCI to abstract use models and models of interaction, then transfer to information service design and function design. The last stage is evaluation: usability testing by scenario, and continuing to alter design of HCI with iterative design to meet the requirements of multi-users, multi-tasks, and multi-sites environment.
