【摘要】：随着普适计算的发展,越来越多的系统服务(如商务、政务、医疗保健、银行业务等)被普通用户使用。作为用户与系统交互的媒介,高可用性的界面有助于普通用户快速掌握系统功能。然而,传统的界面设计方法所设计出的交互系统有以下两个缺点:一方面,用户须有被使用系统的领域知识和经验,与系统的交互须在该领域知识的基础上进行;另一方面,传统用户界面从内部办公人员的角度进行设计,仅强调了内部办公的有效性和高效性,忽略了普通用户对界面上所呈现的信息缺乏理解这一事实。上述缺点由传统设计方法所依据的任务模型决定,因此,由该任务模型设计出的用户界面并不适用于普通用户(非专业领域用户),需要设计新的任务模型以提高用户界面的普适可用性。基于感知控制论的任务分析技术的界面设计方法为上述问题提供了一种可行的解决方案。基于感知控制论的任务分析和建模方法在用户意图层次上,按照用户的概念刻画他们的目标与系统服务之间的关系,而并非如何使用专业领域概念来操作系统服务。因此,基于感知控制论的任务分析和建模方法为非专业领域用户建模和开发方便易用的交互式应用提供了一种潜在的解决方案。因此,本文提出了基于感知控制论的用户界面设计方法(Perceptual-Control-Theory Based for User Interface,PCTBUI)。旨在给用户提供容易理解、易于操作、在意图层次上可以完成任务的用户界面。此方法结合了工业界广泛应用的层次任务分析方法(旨在总体上把握任务的完整性和任务之间的关系)和感知控制论,从而拉近用户和界面之间的距离,使系统具有较高的普适可用性。最后,通过实例分析和评估说明了此方法的可行性和有效性。
[Abstract]:With the development of pervasive computing, more and more system services (such as business, government, health care, banking, etc.) are used by ordinary users. As the medium of user interaction with the system, the high availability interface helps the ordinary users to quickly master the system function. However, the interactive system designed by the traditional interface design method has the following The two shortcomings: on the one hand, the user must have the domain knowledge and experience of the system used, and the interaction with the system must be based on the knowledge of the field. On the other hand, the traditional user interface is designed from the perspective of the internal office staff, only emphasizing the effectiveness and efficiency of the internal office, ignoring the common user's appearance on the interface. The information lacks understanding. The above shortcomings are determined by the task model based on traditional design methods. Therefore, the user interface designed by this task model is not suitable for ordinary users (non professional domain users). A new task model needs to be designed to improve the universal usability of the user interface. The task based on the perception control theory. The interface design method of analytical technology provides a feasible solution for the above problems. The task analysis and modeling method based on the perception control theory, on the user's intention level, depicts the relationship between their target and the system service according to the user's concept, rather than how to operate the system service by using the concept of professional domain. Therefore, the task analysis and modeling method based on perceptual cybernetics provides a potential solution for user modeling and easy to use interactive applications in non professional fields. Therefore, this paper proposes a user interface design method based on Perceptual-Control-Theory Based for User Interface (PCTBUI). It provides users with easy to understand, easy to operate, user interface that can accomplish tasks at the intention level. This method combines the hierarchical task analysis method widely used in industry (the aim is to grasp the integrity of the task and the relationship between tasks) and the perception control theory, so as to close the distance between the user and the interface, so that the system can be used. Finally, the feasibility and effectiveness of the method are illustrated by case analysis and evaluation.
