Abstract

In this article smart appliances are characterized as devices that are attentive to their environment. We introduce a terminology for situation, sensor data, context, and context-aware applications because it is important to gain a thorough understanding of these concepts to successfully build such artifacts. In the article the relation between a real-world situation and the data read by sensors is discussed; furthermore, an analysis of available sensing technology is given. Then we introduce an architecture that supports the transformation from sensor data to cues then to contexts as a foundation to make context-aware applications. The article suggests a method to build context-aware devices; the method starts from situation analysis, offers a structured way for selection of sensors, and finally suggests steps to determine recognition and abstraction methods. In the final part of the article the question of how this influences the applications is raised and the areas of user interfaces, communication, and proactive application scheduling are identified. We conclude with the description of a case study where a mobile phone was made aware of its environment using different sensors. The profile settings of the phone (ringing mode etc.) are automatically selected according to the real world situation the phone is used in.
如何打造智能家电?
在本文中,智能设备的特征是关注其环境的设备。我们介绍了情况、传感器数据、上下文和上下文感知应用程序的术语,因为彻底理解这些概念对于成功构建此类工件非常重要。本文讨论了实际情况与传感器读取的数据之间的关系;此外,还对现有的传感技术进行了分析。然后,我们介绍了一个架构,该架构支持从传感器数据到线索再到上下文的转换,作为构建上下文感知应用程序的基础。本文提出了一种构建上下文感知设备的方法;该方法从情境分析出发,为传感器的选择提供了一种结构化的方法,最后提出了确定识别和抽象方法的步骤。在本文的最后一部分中,提出了这如何影响应用程序的问题,并确定了用户界面、通信和主动应用程序调度等领域。我们总结了一个案例研究的描述,其中移动电话是利用不同的传感器意识到它的环境。话机的配置文件设置(振铃模式等)会根据实际使用情况自动选择。
