摘要
费茨定律(Fitts’Law)是人机交互界面设计中的重要指导理论。因此,费茨定律的讲授是人机交互课堂的重要环节。在本文中,作者以自身教学实践为基础,提出费茨定律的三层次讲解模型(理论层次、应用层次和科研层次),以系统地讲授费茨定律的理论及应用。具体而言,这个模型首先对比香农定理和费茨定律,分析费茨定律起源及其参数含义。其次参考商业操作系统(i OS和Windows)的设计,说明费茨定律的应用场景。最后以发表在人机交互顶级会议CHI上新颖的研究成果为例,阐述费茨定律的理论指导作用。课堂反馈初步说明了该教学模型的有效性。该教学方式不仅为更好地讲解费茨定律提供了借鉴,也为讲授人机交互课程的其他知识给出了思路。
Fitts' law plays an important role in human-computer interface design. Hence, the lecture on Fitts' law is vital in Human-computer Interaction(HCI) courses. In this article, the author proposes a three-level lecture model(theory, application and research levels) based on the author' teaching experience. Specifically, this model first compares Shannon's theorem to Fitts' law so as to analyze the origin of Fitts' Law and the meanings of its parameters. Then this model refers to commercial OS design such as i OS and Windows to illustrate application scenarios of Fitts' law. Last, this model demonstrates the function of Fitts' law as a theoretical guidance by taking research outcomes published in the top level HCI conference CHI as examples.The initial feedback demonstrates the effectiveness of the lecture model. The proposed method not only provides references of how to better lecture on Fitts' law, but also offers thoughts to lecture on other HCI knowledge.
