Extracting Requirements for Ubiquitous Computing Technology-based IS Using Factor Analysis

The paper describes a methodology for extracting the requirements for ubiquitous computing technology-based information system (IS) using factor analysis. The early idea of ubiquitous computing was articulated by Mark Weiser in 1988 and since then has been constantly developed. However, so far there was no any or few research on application of ubiquitous computing to IS. Prior to the development of a ubiquitous computing-based IS model necessary requirements are to be identified. To derive the requirements we refer to conventional research on ubiquitous computing, ubiquitous service and ubiquitous environment, and hence, to their characteristics. Having specified those requirements using factor analysis technique it will be easier to develop a consistent ubiquitous computing-based IS

Determinants of continuance intention of user on smartphone-based traveller information systems in the greater Klang Valley

In these modern-days, the use of mobile traveller information service is pivotal in the efficient and effective running of the transportation system for an urban area. The role of urban facilities managers in urban transportation planning is to develop a plan to provide drivers with real-time traveller information services to enable regional economic growth and transition. Existing research in the mobile information traveller information services area has not deeply investigated the determinants of continuance intention to use smartphone-based traveller information systems (STIS). The purpose of this study is to attempt to do so by investigating STIS users’ continuance intention at the post-adoption phase. This study developed and validated an extended framework based on the expectation-confirmation model (ECM). The 280 STIS users from the Klang Valley highways and major streets participated in the study. The extended ECM results revealed that STIS users’ continuance intention is determined by perceived enjoyment and perceived usefulness of continued STIS use, followed by satisfaction with STIS use. In this study, satisfaction and perceived usefulness are determined primarily by confirmation of expectation from participants’ previous use, except for the perceived enjoyment. The findings of this study have implications for the transportation sectors in planning their strategies to increase users’ continuance intention to use STIS services. Most of the current literature in mobile information services studies focused only on pre-adoption and have paid little attention to user’s continuance intention, especially in the context of smartphone apps or electronic information in the transportation system services. This study fills the theoretical and practical gaps by focusing on the post-adoption phase and developed an extended framework based on the ECM to explain the STIS continuance intention context. In addition, the topic is timely, as mobile information services have been flourishing in the current worldwide transportation sector services

Personalized City Tours - An Extension of the OGC OpenLocation Specification

A business trip to London last month , a day visit in Cologne next saturday and romantic weekend in Paris in autumn – this example exhibits one of the central characteristics of today’s tourism. People in the western hemisphere take much pleasure in frequent and repeated short term visits of cities. Every city visitor faces the general problems of where to go and what to see in the diverse microcosm of a metropolis. This thesis presents a framework for the generation of personalized city tours - as extension of the Open Location Specification of the Open Geospatial Consortium. It is founded on context-awareness and personalization while at the same time proposing a combined approach to allow for adaption to the user. This framework considers TimeGeography and its algorithmic implementations to be able to cope with spatio-temporal constraints of a city tour. Traveling salesmen problems - for which a heuristic approache is proposed – are subjacent to the tour generation. To meet the requirements of today’s distributed and heterogeneous computing environments, the tour framework comprises individual services that expose standard-compliant interfaces and allow for integration in service oriented architectures

A situation-aware mobile traffic information system prototype

With the current evolution of mobile communication and Internet computing mobile services will play an increasing role in future work and private life. Especially enabling mobility in urban and populous areas needs tools for individual traffic planning. In this paper we present a prototype of a traffic information system enabling not only plain route planning, but also advanced services like traffic jam alerting, etc. Using a centralized database architecture our service integrates a location-based service with a situation-aware traffic information system. The fast changing nature of traffic data requires that traffic information is gathered from a variety of on-line Internetsources featuring traffic jam, weather, or road work information. Our asynchronous update strategy of the central service database allows to meet real-time requirements though providing up to date information. In the course of this paper we will investigate all necessary capabilities, present the development of our prototypical system, and give a case study on applying our prototype for real world use. Modern XML technology together with appropriate XSLT stylesheets allows the automatic conversion of generic traffic information for the delivery to a variety of mobile devices. In summary we believe that intelligently joining the latest powerful technologies for preference modeling, database-driven evaluation and standard XML technologies today promises a breakthrough for mobile information systems
