Synthetic and analytic methods for user-computer interaction design

As ways of designing better user interfaces (UIs), human-computer interaction (HCI) models and UI design guidelines can be useful tools. In this paper, a HCI model is first proposed, which is suitable for practical synthetic and analytic activities of UI design. Next, specific synthetic and analytic methods for UI interaction design is proposed, with the aim to make the usability of UIs much better. Finally, in order to demonstrate the usefulness of our methods, an example of evaluating an existing UI is provided.
