Adaptive mobile web interface: user readiness in context

Despite the technological advances in adapting web user interfaces to the small display of handhelds, the role that task nature plays in the formation of user attitude towards adaptive interface designs remains largely unknown. This study compares user readiness towards adaptive web interface design under different task contexts. Capturing such a situated user attitude is valuable for the designers of mobile websites to engage in user–centred design, enhance user experiences, and ultimately improve the viability of mobile information services. Based on a review of relevant theoretical frameworks, a research model was hypothesised and tested with experimental data. The results support the concept that mobile users are generally positive about adaptive interface design, and their preferences are more salient for complex tasks than for routine tasks.

Behavioral Intention to Use Mobile Information Services in Tourism: The Case of the Tourist Guide Dolomitisuperski.Mobi

Mobile information services show great potential both as an on-site information source for customers and as a communication and distribution channel for tourism providers. Although in nontourism domains the adoption rate of using mobile technologies has been growing exponentially, comparable figures are only moderate in travel and tourism. Moreover, relatively little research has been conducted to understand travelers' behavioral intention to use mobile technologies. thus, the article proposes a technology acceptance model which is especially designed for mobile information services in the tourism domain. the model is an extension of the Unified theory of Acceptance and Use of technology, and is empirically tested through laboratory-based usage data obtained from users evaluating a mobile tourist guide developed for the ski resort DolomitiSuperski. Structural equation modeling (SeM) revealed that hedonic quality and social influence are main drivers of the behavioral intention to use mobile technologies in tourism, while monetary transparency and price fairness emerged as major usage barriers.

In recent, library is considered as an integrated knowledge convergence center that can respond to various requests about information service of users. Therefor it is necessary to establish a novel information system based on information communications technologies of the era. In other words, it is currently required to develop mobile information service available in portable devices such as smart phones or tablet PCs, and to establish information system reflecting cloud computing, SaaS, Annotation, and Library 2.0 etc. In this paper we design and implement a library information system using collective intelligence and cloud computing. This information system can be adapted for the varieties of mobile service paradigm and abruptly increasing amount of electronic materials. Advantages of this concept model are resource sharing, multi-tenant supporting, configuration, and meta-data supporting etc. In addition it can offer software on-demand type user services. In order to test the performance of our system, we perform an effectiveness analysis and TTA authentication test. The average response time corresponding to variance of data reveals 0.692 seconds which is very good performance in timing effectiveness point of view. And we detect maturity level-3 or 4 authentication in TTA tests such as SaaS maturity, performance, and application programs.

Dimensions of Autotelic Personality and their Effects on Perceived Playfulness in the Context of Mobile Information and Entertainment Services

Autotelic Personality represents an important individual construct in flow theory yet little is known about its underlying dimensions. Csikszentmihalyi (1988) suggested that the higher the autotelic nature of an individual, the more likely for him/her to experience flow. This study explores autotelic personality, its underlying dimensions and its relationship with perceived playfulness in the context of Mobile Information and Entertainment Services (MIES). This study found Autotelic Personality to be an important quality in order for users to experience perceived playfulness in the MIES context. Several underlying dimensions of Autotelic Personality were identified, including personal innovativeness, self efficacy and control.

Mobile Identity and Financial Inclusion at the Bottom of the Pyramid

ture capital. Movirtu provides mobile-identity management software to leading mobile telecommunications operators. The company’s core geographical focus is Africa and South Asia. It works with mobile operators and non-governmental organizations to serve people who live on incomes of $1-$2/day and can’t afford to purchase or maintain a mobile phone, do not have regular access to electricity, and appreciate the convenience of being able to log in to any handset. Mobile identity services are particularly useful for rural poor women. Much of Movirtu’s customer base lives on $1-2/day. They cannot afford to purchase or maintain a mobile phone but still need access to phone services. This group, which makes up 30-50 percent of our target markets in Africa and South Asia, currently relies on public or shared phones and pay a premium to use a phone, either as a service fee to a public operator or as a sweetener to an acquaintance to offset concerns about compromised confidentiality or credit use. Mobile users who use a shared or public phone have no “identity,” so while they are able to make brief calls or send a text message, no one can reach them individually. They cannot enjoy the full benefits of mobile communication, such as banking or personalized content services, which require a user identity. Movirtu’s Cloud Phone allows users to log in and out of any GSM phone connected to its operator client(s) who have installed Movirtu’s Cloud Phone technology. The Cloud Phone service creates a new customer for the mobile operator and gives the user a mobile identity. This is defined as the unique and secure connection between a mobile user and his or her data, including his or her mobile number and call records, and his or her mobile money account and information services, such as health notifications or agricultural information.

확장 가능한 모바일 기상 정보 서비스를 위한 센서 시스템의 설계

In the mobile meteorological information services, an existing sensor system should be expanded to serve precise information. This is because of large cost problem to add the existing sensors. This thesis proposes a system architecture to construct scalable mobile meteorological information services and suggests mobile phone, sensor network, and public traffic vehicle as expended sensors. The proposed scalable sensors are compared each other and analysed the results to evaluated their strength and weakness. In this system, based on the characteristics of the sense data collected at server, a data processing methods are proposed to support efficient query processing. The proposing data processing methods have several benefits. They compress some data volume sensed by various sources on some area at some time to a logical unit. Still it could preserve same services quality.

A Privacy-Considerate Framework for Identity Management in Mobile Services

The subscribers' personal information and services that mobile operators are able to provide to Web developers offer new and exciting possibilities in numerous domains. However, bringing mobile information services to the Web to enable a new generation of mobile Web services presents several research challenges on identity and privacy management. In this paper, we describe a framework for identity management in mobile services that empowers users to govern the use and release of their personal information. Our framework is based on a brokering approach that intermediates between the mobile operator's information services and the Web service providers. By leveraging on Web services, identity management infrastructure and privacy enhancing technologies, our framework provides an effective, privacy-considerate delivery of services over the mobile Web environment. This paper describes the design principles and architecture of the framework as well as the feasibility, applicability and user-experience evaluation we have carried out.

Voronoi-Based Continuous $k$ Nearest Neighbor Search in Mobile Navigation

Digital ecosystems are formed by “digital organisms” in complex, dynamic, and interrelated ecosystems and utilize multiple technologies to provide cost-efficient digital services and value-creating activities. A distributed wireless mobile network that serves as the underlying infrastructure to digital ecosystems provides important applications to the digital ecosystems, two of which are mobile navigation and continuous mobile information services. Most information and query services in a mobile environment are continuous mobile query processing or continuous k nearest neighbor (CKNN), which finds the locations where interest points or interest objects change while mobile users are moving. These locations are known as “split nodes.” All of the existing works on CKNN divide the query path into segments, which is a segment of road separated by two intersections, and then, the process to find split nodes is applied to each segment. Since there are many segments (due to many intersections, obviously), processing each segment is naturally inefficient. In this paper, we propose an alternative solution to overcome this problem. We use the Voronoi diagram for CKNN [called Voronoi CKNN (VCKNN)]. Our proposed approach does not need to divide the query path into segments, hence improving the overall query processing performance. Our experiment verified the applicability of the VCKNN approach to solve CKNN queries.

Study on Mobile Meteorological Information Services for Urban Area

On the limited urban area, precise measurement of meteorological data is not easy for the cost problem. The facilities collecting the data require high installment costs. The mobile sources can be a solution in city region. For example, a public bus on which some meteorological sensors are installed can act as moving information gathering station. The information is gathered on a server and aggregated to generate useful information for smart phone application. To implement the services, several obstacles are exists. This paper studies on a design of this mobile meteorological information service system for urban area.

Mobile broadcast services with MIMO antennae in 4G wireless networks

The deployment of wireless data broadcast to empower mobile information services as a resource-conserving means offers significant benefits due to the scalability feature offered by the technology. In this paper, we present a novel and holistic data broadcast management approach in 4 G wireless networks with multiple-input multiple-output (MIMO) antennae. The proposed scheme consists of three elements, namely: (i) broadcast ordering; (ii) Global indexing; and (iii) merging data structure. With the integration of these elements, we expect to obtain substantial efficiency for mobile computing clients when retrieving data on-air. We have experimentally evaluated the performance of the proposed model including comparison with the relevant schemes. The results from the experiments affirm the effectiveness of our proposed approach in respect to minimizing query access time and conserving energy utilization of the clients.

The lessons learned from the case study can be of special interest for academicians as well as for practitioners who are particularly concerned with the use of mobile technologies for rural development in emerging economies.

RML: market intelligence in India with mobile SMS intervention

Subject area Agriculture knowledge, market intelligence, emerging business model. Study level/applicability It is best suited to teach undergraduates and graduates in the areas of rural marketing, agri-business management, service management and information and communication technology for development. Case overview India is changing with great pace by inclusive growth on espousal of technology into the mainstream. Indian farmers are wholly depending even now on traditional methods for decision making on entire agriculture supply chain. The constant decision making provides middle men with a chance to exploit and empower themselves on the returns produced by farmers. Technology is creating waves providing an opportunity for farmers to benefit by adopting information and technology to solve their basic livelihood problems. The Thomson Reuter group launched a SMS-based mobile information service to support India's 250-million-strong agricultural community. The service, named Reuters Market Light (RML), is trying to provide a missing link by providing required information in the quickest possible time to farmers; user need-based services are critical to this. How far RML services are delivering in this context is quizzed by some analysts. Thomson Reuter's service started with the global climb down in commodity prices, coupled with increased risk of natural disasters as per experts. The competitors providing similar services at price which differ with RML wondered about the success, scalability and sustainability of its venture. Expected learning outcomes This is a practical view of how these interventions can be better looked at and can get into policy for a framework for rural areas' socio-economic development. Supplementary materials Teaching notes.

Relationship between consumer’s preference and service attributes in mobile telecommunication service

The mobile telecommunication sector is increasing, thus becoming a key area for economic development in global and local markets. One of potential ways to promote competition among service providers is to introduce a mobile number portability (MNP) service. Consumer preferences are estimated using conjoint analysis. Results indicate that subscribers do not consider the MNP service an import attribute, while price and service quality are the most valuable attributes. The results of this study provide important information to implement the first service launch in mobile telecommunication and other similar information and communication technology (ICT) services.

Mobile Services as a Marketing Tool to Enhance Restaurant Revenue: An Exploratory Study

The study's first objective is to discuss the potential of mobile information services' enhancement of the restaurant industry's revenues, and second, to provide practical implications for restaurant managers who wish to capitalize on the opportunities mobile information services offer. According to the survey findings, managers can expect that about a half of their young customers may consider participating in offered services; potential users of restaurants' electronic information prefer receiving discounts, incentive information, and electronic coupons, and prefer not to receive gourmet menu information, pictures, or videos. Potential users of the mobile information services are somewhat reluctant to provide personal information.

Intelligent location-based mobile news service system with automatic news summarization

The accelerated rapid development of wireless network and mobile computing technologies has increased the convenience of mobile information services for obtaining useful information in our daily lives. The technology has thus become an essential research issue. In particular, location-based services (LBSs) on mobile devices can convey location related information to individual users, thus helping users to obtain helpful and adaptive information. Accordingly, this study presents an intelligent location-based service system to provide local news with summaries to personal handheld PDA (Personal Digital Assistant) device based on the user’s location. First, this study proposes a novel multi-document news summarization scheme based on fuzzy synthetic evaluation. This scheme identifies a key paragraph in a news story as a summary based on three evaluation scores, in order to dispatch news information to mobile devices with small screens. Furthermore, to sense a user’s location precisely, the study also develops a practicable location-awareness scheme based on GPS (Global Positioning System) signals to identify the position of a user in the Taiwan area. Finally, an intelligent location-based mobile news service system with automatic news summarization for location-based news services was implemented by combining the proposed multi-document news summarization and user location schemes. The proportion of satisfactory news summaries is up to 86%, and the accuracy of the user location-awareness scheme is up to 90%, according to experimental results in multi-document summarization and user location identification. These experimental results show that the proposed system can be successfully applied in real-world applications for personalized location-based news services.

We report on a broad survey of over 6000 Australian mobile phone users, covering respondents' behaviour and preferences on a range of variables relevant to the consumption of mobile content and information services. Findings from this research inform application developers, content aggregators, content owners, mobile telecommunication companies, handset manufacturers, analysts and other industry partners and may also help to establish guidelines for telecommunication carriers and government policy makers.

Factors affecting the present and future use of mobile data services: comparing the Dutch, Finnish and Greek markets

We study the extent to which regulatory and market-related conditions in Finland, Greece and the Netherlands explain the uptake of advanced mobile data services in these countries. By comparing data from a common survey, models are tested through structural equation modelling. We find significant differences and communalities in the factors affecting the present and future use of mobile services in the three countries, related to personal attitudes towards mobile innovation. We conclude that expectations for the future uptake of mobile data services may be formulated not only through a number of common factors (mobile entertainment services, for example, are influenced by entertainment value in all countries), but also by situation-specific ones (for example, mobile information services are influenced by perceived flexibility in Finland and Greece, and by perceived status enhancement in the Netherlands). Such findings have practical consequences for the design and marketing of mobile services in different markets.
