Building Service UX Index：Measuring UX Satisfaction in Mobile Content Services

사용성 평가는 User Interface(UI)의 완성도를 진단할 수 있다는 측면에서 UX 디자인 프로세스 전반에 걸쳐 활용되고 있다. 그러나 컨텐츠 기반 서비스의 경우 서비스가 실제 시장에서 어떻게 사용자들에게 지각되고, 어떤 경험 요소들이 서비스에 대한 만족도를 결정하는 데 영향을 미치는지 등을 파악하는 데는 사용성 평가만으로는 한계가 있을 수 있다. 비록 사용성이 사용자 경험에 영향을 미치는 중요한 하나의 요소이나, 그 외에 다양한 사용자의 주관적인 태도, 시장 성숙도 및 경쟁 현황 등 시장에서 발생할 수 있는 환경적인 변수 등은 포괄하지 못하기 때문이다. 이에 본 연구를 통해 사용성뿐만 아니라 실제 시장에서 사용자 만족도에 영향을 주는 다양한 내적, 외적 경험 요소들을 밝히고자 하였으며, 이를 통해 모바일 컨텐츠 기반 서비스에서 사용자가 경험하는 전반을 정량적으로 평가하고 진단할 수 있는 UX 인덱스 모델을 구축하였다. 또한 설계된 UX 인덱스를 기반으로 실제 출시되어 운영 중인 서비스를 대상으로 한 정량 설문 분석을 통해 모델을 검증하고, 결과 데이터를 분석함으로써 본 인덱스에 대한 활용 방안을 제시하고자 하였다.

소셜 실감 게임을 위한 이기종 스마트 플랫폼 브릿지 기술

Recently, the concept of mobile content service has changed from providing unilaterally contents for single-device to providing same contents for multi-device. This service should be able to provide diverse contents for multi-devices without platform and specification of multi-device. In this study, we propose a bridge technique of heterogeneous smart platform supporting social immersive game. It is possible to access social immersive game by using a multi-platform bridge. To achieve this, we explain techniques of device connection and data transmission between heterogeneous devices using server-client structure and UPnP. It provides an immersive game environment for multi-user, which is able to play in a public place using big screen.

모바일 웹 서비스에 기반한 문화 콘텐츠의 활용: 『한국향토문화전자대전』의 사례를 중심으로

모바일 및 태블릿 PC의 확산으로 인해 지리적 경계가 무너짐에 따라 글로벌 문화 예술 활동 및 공공문화 콘텐츠 교류가 확대되는 추세이며, 웹2.0의 확산에 따라 사용자는 쉽게 다양한 문화 콘텐츠를 이용할 수 있게 되었다. 그러나 이에 적합한 기술을 적용하고 문화 콘텐츠를 개발하는데 있어 각 지자체 및 연구기관에서는 선례나 기준이 없어 개별적이고 독자적으로 구축, 서비스하고 있는 실정이다. 또한 기존의 콘텐츠 서비스와는 달리 모바일 환경의 특성을 고려하여야 하며 사용자의 현재 상황에 적합한 개인화된 콘텐츠를 적시에 제공할 필요가 있다. 이를 위해서 본 연구에서는 문화 콘텐츠의 모바일 서비스를 위한 기반연구 현황과 모바일 환경을 기반으로 한 문화 콘텐츠 서비스의 표준적이고 효과적인 구축방안을 기초한 한국향토문화전자대전 모바일 웹 서비스 사례를 소개한다.

An Analysis on the Economic Effects of the Market Structure Related to the Platform of Mobile Content Services

We develop a two-sided market model to analyze the Japanese mobile internet market in which revenues from digital content are rapidly expanding. To pursue new revenue from digital content, mobile telecommunications carriers strategically integrate platform functions (PFs) , such as billing and authentication, into their networks. PFs are necessary for content providers (CPs) to charge users, so it is crucial for them to access PFs in a fair and open manner. Consequently, it seems appropriate to examine the need for government intervention in the transactions between CPs and telecommunications carriers, because telecommunications carrier PFs are bottleneck facilities for CPs. However, the effects of possible intervention should be respectively examined as related to the market environment. We studied the effects of market structure on social welfare with a two-sided market model in which a telecommunications carrier sells mobile telecommunications services to consumers and sets the fees for CPs. Apart from preceding literature focused on advertising model, we introduce a billing model in which the telecommunications carrier purchases content from CPs and sells the content to consumers. A monopolistic telecommunications market is assumed in our model and three different market structures are compared to each other; (1) vertical integration, (2) monopoly in content market and (3) duopoly in content market. First, we found that both the industry profit and the social welfare of (1) were largest. Second, our model also showed that the social welfare of (3) exceeded (2) . However, the industry profit of (2) surpassed (3) . These results indicate that CPs have the incentive to monopolize competitive content market, but content monopoly decreases social welfare. Therefore, if our model adequately works in a market with content industry independent from telecommunications carriers, government intervention should be considered to maximize social welfare. Finally, we extracted additional implications from the model. The welfare of (3) may exceed (1) because an increase in the number of CPs creates product differentiation that can increase consumer utility. Based on this idea, we also examined the effects of some parameters on social welfare as a step toward further analysis.JEL Classification: D11, D85, R11

Secure and traceable multimedia distribution for convergent Mobile TV services

Few papers have focused on secure mobile multimedia distribution that protects both the confidentiality and copyright in mobile multimedia services. In this paper, a secure multimedia distribution scheme is presented for a ubiquitous mobile content service, i.e., the Mobile TV based on the converged DVB-H (Digital Video Broadcasting – Handheld) and GPRS/GSM. At the server side, the Joint Compression and Encryption method is proposed to encrypt video contents. At the mobile terminal side, the Joint Decryption and Fingerprinting method is proposed to decrypt video contents and simultaneously embed the mobile terminal’s identification information. When the media content is illegally redistributed to public networks, such as Internet or public TV, the proposed Fingerprint Detection and Traitor Tracing method will be used to identify the illegal redistributor. To show the proposed scheme’s prior performances, the existing secure media distribution schemes are reviewed, and the comparative evaluations are done. The analysis and experimental results show that the proposed scheme is more suitable for secure mobile multimedia distribution. The work is expected to attract more researchers.

Mobile Data Service usage and preference: an investigation of Australian consumers

Understanding mobile phone users' behaviour and sentiment is essential for the commercial success of mobile content and information services. This paper aims to enhance this understanding through analysing data gathered from a consumer survey. 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.

Comparing the perceived value of information and entertainment mobile services

AbstractThe importance of perceived value in customer decision making is well known. However, few studies assess empirically the direct effects of various perceived value dimensions on post‐purchase behavior. This article examines differences between information and entertainment mobile content service users in how their value perceptions influence intentions to repurchase, intentions to spread positive word of mouth, and willingness to pay a price premium. The direct effects of four value dimensions are analyzed: monetary, convenience, emotional, and social value. Within this study we also propose and test the antecedent effects of conditional and epistemic value. This approach advances the value literature through increasing our understanding of how individual value dimensions influence post‐purchase behavior and of the role of epistemic and conditional value. Using a sample of 579 mobile service users, results are analyzed with multi‐group structural equation modeling. The findings support use of multidimensional value and loyalty constructs to identify differences between service user groups, and argue for the use of differentiated value‐based marketing strategies for entertainment and information mobile services. © 2008 Wiley Periodicals, Inc.

Mobile Semantics: Defining Concepts and their Interrelationships

Abstract As service offerings and technologies constantly develop there seems to be confusion over what we are actually talking about when we talk about mobile services. A requirement for constructing an organized body of knowledge in a specific area of research is the clarity of its basic concepts. Often, we are not specifically interested in defining things but to examine and discuss the subjects of our primary interest we need unambiguous and shared definitions of our key concepts. Although many relevant concepts undoubtedly have clear definitions in the minds of experienced scholars working in the field of mobile offerings, for some reason these definitions are not well articulated or easily found in published form. With a focus on business‐to‐consumer mobile offerings, this paper addresses this lack of shared definitions. As the main contribution definitions of business‐to‐consumer mobile services and mobile content services are introduced, existing definitions for related concepts are presented and ...

Control Devolution as Information Infrastructure Design Strategy: A Case Study of a Content Service Platform for Mobile Phones in Norway

This paper depicts the results of an empirical case study on how two Norwegian telecommunications operators developed a business sector information infrastructure for the provision of mobile content services. Focusing on the context of this technology's development, and the strategic issues behind its design, implementation and operation, control devolution as a design strategy is explored. This analysis draws on insights presented by Claudio Ciborra's in his study of the change from alignment to loose coupling in the Swiss multinational Hoffmann-La Roche. This paper illustrates how control is played out on different levels, and balanced against autonomy. The theoretical implications of this paper highlight how the differences and transformations between information systems and information infrastructures are conceptualised, with the development of the latter better understood in light of a balance between control and autonomy. Consequently, it is suggested that control devolution as a design approach should be based on a deep understanding of the existing control/autonomy balance as well as the distribution of resources, risks and the ability and willingness to innovate.
