The bus arrival time is primary information to most city transport travelers. Excessively long waiting time at bus stops often discourages the travelers and makes them reluctant to take buses. In this paper, we present a bus arrival time prediction system based on bus passengers' participatory sensing. With commodity mobile phones, the bus passengers' surrounding environmental context is effectively...
The rise in popularity of location disclosure brings privacy concerns to the forefront. Mechanisms are needed that empower users to personalize the balance between the benefits of location awareness and privacy. This paper presents TISS-loc, which leverages trust management foundations to enhance control of location disclosure. TISS-loc supports location obfuscation to balance privacy and the benefits...
We propose a novel spatial information system architecture based on ucode, which is a unique identifier. The model includes not only outdoor location but also indoor location such as room and elevator, utilizing geographic identifier. In our system architecture, we propose Web-based APIs for both of outdoor and indoor spatial information in order to mush it up with existing web and mobile applications...
In recent years several authors and projects have addressed the need for an architecture for collecting and managing context information. Most of the approaches have either been purely based in middlewares unable to address the heterogeneity of components and services platforms, or have been built around Web based technologies that are unable to cope with the realtime and reactiveness requirements...
Although the conventional Social Network Services (SNS) provides a solution for internetworking social users to share information and social media contents based on the Web, there are further requirements to support increasing demands of social users with commencing Web 2.0 and ubiquitous computing technologies. Especially with increasing popularity of the User Created Contents (UCC) and handheld...
Mobile learning is an increasingly important source of educational material. However, only scant research has been directed towards how this educational information can be made accessible to the deaf and hearing impaired communities. Sign language is an effective method of communication for normal people to communicate with these two groups. In this paper, we propose to develop a sign language learning...
In this paper, we present a novel method for image annotation and retrieval on mobile device by using contextual information. Image annotation is an effective way for content based image retrieval. However, manual annotation is an expensive and time consuming work, especially for mobile device. Here, we propose a semi-automatic way to give image annotation on mobile device. There are rich contexts...
In this paper, we propose a context-aware Input Method Editor (IME) as a ubiquitous service for improving the input of text on mobile devices. In our proposed IME, it estimates the context of users according to position information from GPS (Global Positioning System) sensor or a presence information from the Internet. Simultaneously, it generates a personal context-aware dictionary dynamically from...
Recent developments in technology and industry show that users are increasingly becoming the focus of technological development. Not only new applications capable of performing certain tasks are brought to potential users, but also technical innovations that are built around people in order to best fit their needs and make their lives easier. In this paper, we discuss in detail our newly developed...
The driver assistance system is more and more widely used with the development of automobile industry. The driver assistance system based on pervasive computing integrates the function of computing, communicating and sensing, which can assure the driving safety and prejudging the traffic emergency by sharing the information among vehicles of the same district. The structure and working principle of...
Location-aware is becoming an important aspect of mobile computing. A core problem in location-aware service is the determination of physical location. For applications in open, outdoor areas, the Global Positioning System is a common choice. Although GPS offers near-worldwide coverage, its performance degrades indoors and in high-rise urban areas. By using signal strength, it is possible to locate...
In 1995, Mark Weiser introduced a scenario about the future life, where everyday objects are equipped with smart functions and the environment helps us to fulfill our everyday tasks. This paper shows how Weiser's scenario can be realized by today's available technologies. We combine PerFlows (to model the flow of daily tasks) and the Nexus context provisioning platform (to model and provide necessary...
To support healthcare organizations responses, many companies have started solutions to be satisfied the specific requirements of healthcare programs, and plans. This paper presents a designed and implemented care system for health diagnosis based on GPS location in the hospital. The designed handheld care system is implemented using an embedded Visual C++4.0 and Pocket PC2003 software development...
In ubiquitous computing, as more and more devices are introduced into the environment, new applications are made possible that exploit device capabilities in new ways. Currently, however, there is a mismatch between the effort involved in implementing these applications and the benefit they provide. A proposed solution is to use a service oriented architecture and implement applications as composite...
