【摘要】：目前,硬件技术与无处不在计算技术的快速发展与更新,使得多种移动设备在输入输出通道上呈现出多样性与异构性。由于缺乏对多种不同移动设备的抽象,用户界面必须针对多种不同设备的特性为同一应用进行反复开发,以便满足现有设备异构性的需求。但是,这常常带来大量额外的成本及努力代价。因此在多设备环境下,如何高效地对多设备移动用户界面进行开发成为界面开发者亟需解决的问题。为了解决多遍用户界面开发所带来的问题,界面研究者提出了MBUID(Model-Based User Interface Development)方法。MBUID能够对界面的不同层次抽象,通过模型的定义与模型间的转换生成最终界面,为多设备界面的设计开发提供一个系统化方法。其中的抽象用户界面模型能够在较高层次为实现“一次设计,多次开发”的快速界面开发提供可能,因此成为移动多设备环境下用户界面设计开发的有效解。然而,目前抽象界面的建模表示存在几点问题。一方面,目前并不存在MBUID方法中模型的定义标准,现有方法模型定义大多较为复杂且缺乏规范;另一方面,现有的抽象界面模型较难为多种移动设备提供统一描述,抽象界面模型在多设备移动界面的设计实现中难以有效复用。因此,本文对多设备移动界面的设计开发过程进行重新设计,提出一种界面功能性与可用性分离的SFAU(Separated Functionality And Usability)框架。在其抽象层,对当前多种移动设备的设备特征进行抽象,提出抽象设备的概念。通过抽象设备的定义标准,实现一种标准化面向抽象设备的移动界面模型的建模方法,同时为多设备移动界面提供一种统一规范化的界面交互功能描述,优化界面设计的复用。最后,本文通过一个实例对提出的方法进行了评估分析,证明界面设计者只需在抽象设备上设计一次统一的移动用户界面抽象描述,即可通过映射转换实现在多种移动设备上最终界面的生成。
[Abstract]:At present, with the rapid development and update of hardware technology and ubiquitous computing technology, many kinds of mobile devices present diversity and heterogeneity in input and output channels. Due to the lack of abstraction of many different mobile devices, the user interface must be repeatedly developed for the same application according to the characteristics of many different devices in order to meet the requirements of the heterogeneity of existing devices. However, this often brings a lot of additional costs and effort costs. Therefore, how to develop mobile user interface efficiently in multi-device environment becomes an urgent problem for interface developers. In order to solve the problems caused by the multi-pass user interface development, interface researchers put forward MBUID (Model-Based User Interface Development) method. MBUID) can abstract different levels of interface, and generate the final interface through the definition of model and the transformation between models. It provides a systematic method for the design and development of multi-device interface. The abstract user interface model can provide the possibility for the rapid interface development of "once design, multiple development" at a higher level, so it becomes an effective solution for user interface design and development in mobile multi-device environment. However, there are several problems in modeling the abstract interface. On the one hand, there is no model definition standard in MBUID method, most of the existing method model definitions are complex and lack of specification. On the other hand, the existing abstract interface model is difficult to provide unified description for many mobile devices, and it is difficult to reuse the abstract interface model in the design and implementation of multi-device mobile interface. Therefore, the design and development process of multi-device mobile interface is redesigned in this paper, and a SFAU (Separated Functionality And Usability) framework which separates interface functionality from usability is proposed. In the abstract layer, the device features of various mobile devices are abstracted and the concept of abstract device is proposed. Based on the definition standard of abstract device, a modeling method of standardized mobile interface model for abstract device is implemented. At the same time, it provides a unified and standardized interface interaction function description for multi-device mobile interface, and optimizes the reuse of interface design. Finally, an example is given to evaluate and analyze the proposed method. It is proved that the interface designer only needs to design a unified abstract description of mobile user interface on an abstract device. It can realize the final interface generation on a variety of mobile devices through mapping transformation.
