随着物联网(IoT)技术的普及,越来越多的工程系统集成了上下文感知功能。不言而喻,功能分析是成功开发此类上下文感知系统(CAS)的关键过程。由于现有的功能分析方法主要用于开发传统的工程系统,因此本文旨在开发一种结构化方法来协助工程师进行CAS的功能分析。本研究基于交互视角下的情境概念,分析了CAS情境的构成及其基本特征。然后提出了一种结构化的功能分析方法,系统地阐述了如何定义和分析CAS的上下文、如何从上下文中识别功能以及如何开发CAS的功能结构。通过对自助结账系统功能分析的案例研究来论证所提出的方法,表明所提出的方法可以帮助设计者有效地进行CAS的功能分析。
With the popularity of IoT (Internet of Things) technology, more and more engineering systems are integrated with context-aware functionalities. It is self-evident that functional analysis is a critical process for successful development of such context-aware systems (CASs). Since existing functional analysis approaches are primarily for developing traditional engineering systems, this paper aims at developing a structured approach for assisting engineers in carrying out functional analysis of CASs. Based on the concept of context from an interactive perspective, this research analyzes what constitutes the context of a CAS and its basic features. Then a structured approach for functional analysis is proposed, which systematically elaborates how to define and analyze the context of a CAS, how to identify functionalities from the context, and how to develop the functional structure of a CAS. A case study of the functional analysis of a self-service checkout system is employed to demonstrate the proposed approach, which shows that the proposed approach can help designers carry out functional analysis of CASs in an effective manner.
