Critical Success Factors of Location-Based Services

Location-based services evolved with the advancement in mobile technology and wireless technology. Researchers have studied location-based services in terms of privacy, trust, and user acceptance. Statistics suggest the percentage of location-based services users is still relatively low. Therefore, the main objective of this study was to gain a comprehensive and holistic understanding of the critical success factors of location-based services. The electronic brainstorming approach was used to gather the opinions of an expert group of practitioners, researchers, and users on the critical success factors of location-based services. Through grouping similar factors together based on past literature, 15 categories of critical success factors were developed. These 15 categories were ranked and rated according to importance. The results showed that speed, real-time or up-to-date information, cost, usefulness or benefits, and simple or ease of use are the five most important critical success factors. The results of this research highlight potential areas of research, and research and development. The results of this study also provide guidelines for practitioners to create a competitive location-based services strategy to increase consumer adoption. Advisor: Keng L. Sia

Mobile Services in Hubei: Adoption Model and Empirical Analysis

Mobile Commerce has developed rapidly in China with the characters of ubiquity, location relevance, convenience and personalization. The researches on technology, value chain, business models, user adoption have become a hot topic among academics. Based on the classical Davis’ TAM theory and the expansions of it, and the predecessors\u27 research on perceived enjoyment and perceived cost, this study builds an adoption model of Mobile value-added services in Hubei Province. In the variety of individual mobile value-added business, four most commonly used services are extracted in this study ,including Mobile Instant Message, Multimedia Messaging Service, WAP Web browse and Multi-media Downloads to represent the overall situation. According to the result of empirical analysis based on valid data of questionnaires, perceived enjoyment and perceived cost are the most influential factors. Six of the seven hypotheses in this study are verified

Internet Localization of Multi-Party Relay Users: Inherent Friction Between Internet Services and User Privacy

Internet privacy is increasingly important on the modern Internet. Users are looking to control the trail of data that they leave behind on the systems that they interact with. Multi-Party Relay (MPR) architectures lower the traditional barriers to adoption of privacy enhancing technologies on the Internet. MPRs are unique from legacy architectures in that they are able to offer privacy guarantees without paying significant performance penalties. Apple's iCloud Private Relay is a recently deployed MPR service, creating the potential for widespread consumer adoption of the architecture. However, many current Internet-scale systems are designed based on assumptions that may no longer hold for users of privacy enhancing systems like Private Relay. There are inherent tensions between systems that rely on data about users -- estimated location of a user based on their IP address, for example -- and the trend towards a more private Internet. This work studies a core function that is widely used to control network and application behavior, IP geolocation, in the context of iCloud Private Relay usage. We study the location accuracy of popular IP geolocation services compared against the published location dataset that Apple publicly releases to explicitly aid in geolocating PR users. We characterize geolocation service performance across a number of dimensions, including different countries, IP version, infrastructure provider, and time. Our findings lead us to conclude that existing approaches to IP geolocation (e.g., frequently updated databases) perform inadequately for users of the MPR architecture. For example, we find median location errors >1,000 miles in some countries for IPv4 addresses using IP2Location. Our findings lead us to conclude that new, privacy-focused, techniques for inferring user location may be required as privacy becomes a default user expectation on the Internet

Examining the Determinants of Mobile Location-based Services’ Continuance

The continuance of use is an important topic of IS research. However, in the past, many researchers have focused on adoption rather than IS continuance. Studying continuance is of equal importance, because if use does not persist, this may limit the revenues of the provider. This is particularly true for consumer-oriented services, which rely on advertising, or subscription-based revenue models. In this paper, we investigate the determinants of location-based services (LBS) continuance as a relevant case study for the examination of IS continuance generally. A research model is developed and empirically tested through a survey of a representative sample in Germany. The proposed model builds on and extends the Limayem et al. model of IS continuance. Our analysis highlights the importance of habit and emotion in LBS continuance. The results indicate that habit has a stronger predictive power than continuance intentions for LBS continuance and that emotions are an important driver for user satisfaction with LBS

Exploration of location-based services adoption

As mobile technologies become more ubiquitous in the general population, it is reasonable to assume that individuals will consume services and software to enhance their aspirations and entertainment desires. This paper discusses a controlled experiment to explore aspects of user perceptions of their use of location-based services. This study examines a location-based service prototype experiment and analysis based on the UTAUT model. The results show significant indicators that suggest behavior patterns of early adopters of location-based services are being observed. We discuss these influences and attempt to explain their significance. Moreover, more curiously we discuss why some of our model was unsupported and postulate why

The influence of national culture on the attitude towards mobile recommender systems

Copyright @ 2013 Elsevier B.V.This study aimed to identify factors that influence user attitudes towards mobile recommender systems and to examine how these factors interact with cultural values to affect attitudes towards this technology. Based on the theory of reasoned action, belief factors for mobile recommender systems are identified in three dimensions: functional, contextual, and social. Hypotheses explaining different impacts of cultural values on the factors affecting attitudes were also proposed. The research model was tested based on data collected in China, South Korea, and the United Kingdom. Findings indicate that functional and social factors have significant impacts on user attitudes towards mobile recommender systems. The relationships between belief factors and attitudes are moderated by two cultural values: collectivism and uncertainty avoidance. The theoretical and practical implications of applying theory of reasoned action and innovation diffusion theory to explain the adoption of new technologies in societies with different cultures are also discussed.National Research Foundation of Korea Grant funded by the Korean governmen

Who actually wants to use ‘the killer app’? Perceptions of location based services in the young and old

This paper describes the results of two qualitative case studies that assessed the perceptions of Location Based Services (LBS) with two UK user groups: a family with a behaviour-disordered teenager, and a group of older adults. The family (n=2) and older adults (n=13) were interviewed individually after experiencing LBS. The data from the interviews were thematically analysed with the aid of Nvivo software, and organised into themes to better understand attitudes towards LBS technology. Whilst both groups had the opportunity to use, adapt to and experience LBS, perceptions of ‘cool’ and ‘trendiness’ affected judgments of it, and their subsequent usage intentions. The family adopted the LBS system fully, with the device aiding navigation, and ultimately developing trust. Their teenage son also embraced the technology, aided in part by the unobtrusive and ‘trendy’ nature of the mobile phone the LBS was deployed on. In contrast, the older adults felt that LBS could not assist them in any way, and were concerned about the potential for invasions of privacy. This work highlights clear generational differences in the acceptance of LBS, and suggests consideration is needed for the future design of LBS to ensure suitability for the user

Mobile travel services: A three-country study into the impact of local circumstances

In this paper we explore the difference in acceptance patterns of mobile services that are related to travelling in three countries: Finland, The Netherlands and New Zealand. The objective of this paper is to understand differences in the use of Mobile Travel Services in three countries that differ with regard to national travel patterns. This paper also contributes to the discussion of the relevance of the Technology Acceptance Model for mobile applications by focusing on the importance of context characteristics, such as the degree of mobility of the user, the social situation people are in, and their need for social interaction. Based on surveys in the three countries as executed in 2009, we use structural equation modelling to find differences in patterns. The paper concludes that context factors have an impact on the relation between the core concepts as used in TAM and DOI approach, and that t here is a clear need for closer research in the moderating effect of physical (e.g. mobile and fixed context) and social context, as well as the need for social interaction. Moreover it is clear that country specific characteristics play a role in the acceptance of mobile travel services. As we pointed out in many of our research projects before the acceptance and use of mobile services requires deep understanding from individual, context and technology related characteristics and their mutual interactions
