| Popis: | On the traditional Internet, social computing or so-called Web 2.0 applications have become widespread in recent years. The term “Web 2.0” was coined by Tim O’Reilly in 2005 [34] and is often associated with applications such as wikis, blogs, photo- and video-sharing sites, social-networking sites, Web-based communities, Web services, mash-ups, and folksonomies. All of these Web 2.0 applications share some common aspects, including collaboration, interoperability, user-created information, and information sharing on the World Wide Web. The same trend is now spreading to the mobile Internet, for example, through moblogs [1,11], various location-based mobile hypermedia services [12], and pervasive games [16,37]. At the same time, advances in bandwidth and new mobile devices are promising access to information on the Web from anywhere, at anytime, and on any device, thus allowing users to access and produce information even when mobile. While this promise sounds tempting, it has become evident that mobile devices do not support the same ease of interaction as we have come to know and expect from desktop computers. This is mostly due to the smaller screens sizes and limited input capabilities, resulting in less than optimal user experiences when accessing Web services through the traditional interfaces. Furthermore, a user is never anywhere, anytime, or using any device, that is, users are always at a specific place, at a certain time, and using a particular device, and our activities are anchored within a physical and digital context, which changes as we move about or engage in different activities. Based on this observation, we focus in this chapter on how to develop context-aware Web applications that take the user’s context into account in order to create applications that are more optimized toward mobile devices and that make it easier to present information that are relevant to the user in his or her current situation. Cues about the user’s context can be acquired from a number of places. We provide several examples on how to utilize location information (e.g., from GPS sensors) and physical TAGs (e.g., 2D-barcodes or RFID-codes) to support Web 2.0 applications that are anchored into a user’s context and provide information tailored to the physical environment (Figure 7.1). |
