基于感知控制的场景界面设计方法

在普适环境下，计算环境的复杂性使普通用户不易通过预定义的操作来控制系统的状态，致使用户界面设计不能正确反映系统 的特征。为此，提出一种基于感知控制的场景设计方法。该方法利用感知控制理论对使用场景进行分析，导出用户意图控制的对象及策 略，并在此基础上重新设计使用场景，从用户任务的角度出发，使所得到的界面满足用户感知控制的需要。通过案例分析证明该方法的有效性。

Scenario Interface Design Method Based on Perceptual Control

In the pervasive environments,complexity of computing environment makes the user hard to control the states of the system with the predefined actions.The diversity of users,their tasks and techniques demands the correct presentation of the system＇s states to be considered at the beginning of design.For this purpose,this paper presents a new approach to user interface design with scenarios,based on perceptual control theory.The main point of the approach is to derive the objects that are significant for the user understanding and controlling the system,and the means for the control,from the analysis of scenarios.Result gained from the process is used for the re-design of scenarios.The approach is concerned with user＇s task and the purpose of which is to satisfy the user＇s needs.Case analysis show the availability and effectivity of this new approach.
