基于知觉控制的用户界面设计研究

Research on Perceptual-control-based Design for User Interface

随着普适计算环境的迅猛发展,越来越多的普通大众需要自己来完成过去必须由业务人员代理才能完成的任务。这使得传统面向业务的交互设计技术不再满足大众对普适计算的可用性需求。提出一种基于知觉控制的用户界面设计技术,旨在给普通大众提供一种易于学习、理解、操作的用户界面。该用户界面设计技术采用基于知觉控制的任务分析以及"参与式设计"的方法,使得用户能够在意图层次,而非业务层次,进行交互,以满足普适环境下可用性设计的需求。

With the soaring development of pervasive computing environment, an increasing number of folks need to conduct tasks that used to be completed with the help of business agents in the past. This makes traditional interactive design techniques of business orientation difficult to meet the common users＇ usability requirements for the environment. In this paper, we present a design technique for user interfaces based on the perceptual control theory. It enables to provide usable user interfaces, which are easy to learn, to understand and to manipulate for the common users. For the purpose of satisfying the usability requirements in the pervasive computing environment, this design technique introduces a technique of task analysis in accordance with perceptual control theory and a process of participatory design, to help the users making interaction at the task level instead of at the business level.
