人機互動是門跨領域的學科，專門研究各種人類與電腦間的互動方式，以設計出更符合使用者需求的資訊系統。本文所談之互動設計係指人機互動領域中偏設計端的考量，不涉及工程或社會層面的討論。作者除了介紹以使用者為中心的設計考量之外，還探究了使用性與互動設計原則。基於近年來相關研究已大量轉向以網路為基礎的人機互動，作者呼籲：研究者應考量網路媒體的整合性、時空的無限性，以及技術的更新度，對網路互動技術的發展與人機互動的設計研究進行整合性的思考，應能產生更宏大的學術及應用價值。

　　　　　Human-Computer Interaction (HCI) is an interdisciplinary field in which research interest is focused on a variety of ways of interaction between users and computers. The aim of the research is to build a user-centered information system. This paper is concerned with the design issues of the HCI area, rather than the engineering and sociological aspects. In addition to the "User-centered Design," this paper also discusses the issues of usability and design principles. While a great deal of HCI research is now turning to the Internet-related areas, the authors claim that the research must be focused on the integration of design consideration and technological development, in order to achieve a more meaningful outcome.
