在普适计算环境中，可穿戴计算机由于提供了人与计算机之间的接口而变得越来越重要。然而，分布式、动态、异构的计算环境给其带来了许多挑战。最重要的是，可穿戴计算机具有用于用户界面的有限I/O设备。因此，存在许多上下文感知应用程序来为用户提供便利。但是每个应用程序都应该为找到相应的数据而受苦。因此，通过维护用户活动及其派生的元数据来支持文件服务中的上下文感知对于这些应用程序非常重要
在本文中，我们提出了一个上下文感知的文件服务，适用于可穿戴计算环境，提供一个方便的数据共享服务之间的设备和用户。为了实现我们的工作，我们提出了一个基于本体的上下文感知文件元数据管理方案
最后，我们使用UPnP[7]和WebDAV[8]技术实现了早期原型，并使用OWL[9]定义了源本体，并仍在完善系统设计。我们相信，这项工作可能是一个主要的参考，为新一代的文件管理技术在无处不在的计算环境
In the ubiquitous computing environment, wearable computers are becoming more and more important because they provide an interface between human and computers. However, there are many challenges that come from its distributed, dynamic, heterogeneous computing environment. Most of all, an wearable computer has limited I/O devices for user interface. Thus, there are many context-aware applications to provide convenience for users. But each application should suffer from finding corresponding data. So, it is very important to support context-awareness in a file service for these applications through maintaining user's activities and metadata derived from them
In this paper, we present a context-aware file service suitable for the wearable computing environment to provide a convenient data sharing service among devices and users. To realize our work, we present an ontology based file metadata management scheme for context awareness
Finally, we implement the early prototype by using the UPnP[7] and WebDAV[8] technologies and define source ontology by OWL[9] and are still refining the system design. We believe that this work could be a predominant reference for a new generation of file management technology in the ubiquitous computing environment
