The purpose of this study is to measure the satisfaction factors of user experience of 'Unlimited subscription service' among subscription services and analyze them based on economic and cultural perspectives. By recruiting the '20-'30s who had experienced using service, they attended a survey which was based on the reconstructed honeycomb model of Peter Morville. As a result of the survey, in terms of economic perspective, cost of service, and the ease of subscription inflow were the main satisfaction factors. From a cultural perspective, the familiarity with service and belief and experience of sharing content with people around them were the main satisfaction factors. Therefore, it can be inferred that the satisfaction of the user experience of the subscription service should be firstly satisfied with economic satisfaction, which leads to cultural satisfaction. This study is expected to be used as research data on user experience and satisfaction factors of unlimited subscription service.

The purpose of this study is to define determinants of VoIP user acceptance and to verify significant causality among latent variables - performance expectancy, effort expectancy, cost expectancy, social influence, facilitating conditions, behavioral intend, use behavior - based on UTAUT model. We presented the expanded hypotheses including the new factor, cost expectancy and analyzed the moderating effect of user age, gender and usage experience variables. For a accuracy of predicted results, we focused on survey analysis with 641 real user samples. Compared to previous studies, it is meaningful that this research verified the conceptual difference between behavioral intention and usage behavior. As a result, all proposed hypotheses accepted and moderating effects are supported significantly in age and use experience moderating variables.

This study, for learners using online and offline tools, understood the structural relationship of user experience of smart learning app on continuous use intention through the technology acceptance model, and classified the learning type characteristics. In addition, based on the experience of using the smart learning app, we explored ways to improve the design of the user experience design for learning tools and contents. For this purpose, the usage perception of 84 middle and high school students of the developed smart learning learning app was investigated after using it for 2 months, and the data were analyzed using the PLS structural equation technique. The main results of this study are as follows. First, system and content user experience had a significant effect on perceived usability and perceived ease of use, and the effect on continued use intention through attitude was significant. Second, there was a significant difference in the effect of system user experience on perceived usefulness in multi-group comparative analysis and gender group. In the preferred learning group, it was the path from perceived ease of use and perceived usefulness to attitude and intention to continue using that showed a significant path difference. Third, as a result of classifying the most commonly used learning types by the multidimensional scale method, the types separated into low dimensions were found to be four types: offline sync type, online sync type, ubiquitous learning type, and self-direct learning type.

The purpose of this study was to propose a "user experience (UX)-centered product development process" so that the product design development process using the service design process can be systematized and used in practice. In a situation in which usability research on office phones is lacking compared to general home phones, this study expands to a product-based service design point of view rather than simple product development, intending to research ways to provide user experience value through office phone design in smart office. This study focused on extracting UX-centered user needs using the service design process and developing product design that realizes user experience value. In particular, the service design process was applied to systematically extract user needs and experience value elements in the product development process and to discover ideas that were converged with product-based services. For this purpose, the "Double Diamond Design Process Model," which is widely used in the service design field, was adopted. In addition, a product design development process was established so that usability improvement plans, user experience value elements, and product-service connected ideas could be extracted through a work-flow in which real users and people from various fields participate. Based on the double diamond design process, in the "Discover" information collection stage, design trends were identified mainly in the office phone markets. In the "Define" analysis and extraction stage, user needs were analyzed through user observation, interview, and usability survey, and design requirements and user experience issues were extracted. Persona was set through user type analysis, and user scenarios were presented. In the "Develop" development stage, ideation workshops and concept renderings were conducted to embody the design, and people from various fields within the company participated to set the design direction reflecting design preference and usability improvement plans. In the "Deliver" improvement/prototype development/evaluation stage, a working mock-up of a design prototype was produced and design and usability evaluation were conducted through consultation with external design experts. It is meaningful that it established a "UX-centered product development process" model that converged with the existing product design development process and service design process. Ultimately, service design-based product design development process was presented so that I Corp.'s products could realize user experience value through service convergence.

Recently, product design innovation to improve user experience has been perceived as a core element of enterprise competitiveness due to the fierce market competition and decrease of the technological gap between companies, but there is insufficient services to support the product experience evaluation of small and medium-sized companies (SMCs). The aim of this study is to develop a web-based product user experience evaluation and certification system supporting product design practices for SMCs. For system interface design, we conducted systematic functional requirement elicitation methods such as user survey, workflow analysis, user task definition, and function definition. Then main functions, information structure, navigation method, and detailed graphic user interfaces were developed with consideration of user interactions and requirements. In particular, it provides the databases for evaluation efficiency to support the evaluation process above a certain level of performance and efficiency, and knowledge databases to utilize in the evaluation and product design improvement. With help of the developed service platform, It is expected that the service platform would enhance SMCs' product development capability with regard to the user experience evaluation by connecting the consulting firms with SMCs.

본 논문에서는 모바일 애플리케이션의 사용자 잔존율 향상을 위한 방안으로써 내러티브 모션을 기반한 온보딩을 제안한다. 모바일 기술의 발전과 새로운 미디어에 대응하는 디지털콘텐츠 애플리케이션에 대한 관심이 증가하고 있는 가운데 사용자에게 외면받아 사라지는 애플리케이션의 증가가 가속화되고 있다. 이에 따라 사용자의 긍정적 경험 제공을 위한 사용성 향상 연구는 빠르게 진행되고 있으나 애플리케이션의 첫인상과 지속적인 사용을 결정하는 온보딩에 대한 연구는 아직 미비하다. 경쟁이 가속화 될수록 보다 효과적인 사용자경험을 제공하기 위한 온보딩 개발의 중요성은 증대되어 갈 것이며, 결국 온보딩 개발의 핵심 쟁점은 사용자의 긍정적인 인지적 반응과 태도를 이끌어낼 수 있는 요인인 모션이 될 것으로 예측된다. 따라서 본 논문에서는 모바일 온보드에서 제공되는 애플리케이션의 다양한 특성을 표현하기 위한 요인으로서 내러티브 모션을 제시하고 애플리케이션 지속사용 여부에 영향을 미치는 요인을 도출하여 둘의 상관관계를 실증적으로 분석함으로써 앞으로 등장할 새로운 서비스 및 플랫폼의 애플리케이션 개발 필요한 모션요소를 도출하고자 한다.

다양한 디지털 가전제품을 제조하는 회사들은 초기에 제품 하나하나에 제품의 사용경험을 담는데 비중을 높여 개발을 하였다. 하지만 제품이 알려지고 종류가 많아지면서 각 제품들을 아우르는 사용자 경험요소 통합화가 필요하게 되었다. 이에 다양한 화면 사이즈와 Input Device를 가진 Handheld Device들 간의 일관된 사용 경험(user experiences)을 제공하는 것을 목적으로 하는 연구가 진행되었다. 대상이 된 제품들은 Digital Media Broadcasting의 수신, Multimedia 파일이 재생, 파일 creation 등이 가능한 Handheld Devices였고, 각 제품들은 특정 기능에 충실한 UI를 구현하고 있다는 특징이 있다. 따라서, 기존 제품의 사용성을 저해하지 않는 수준의 표준화가 필요하며 기존 UI 사용성과 표준화 UI 사용성 간의 조화가 중요 하였다. 기존 제품의 개별 특징을 분석하고 Handheld Device의 사용자 요구사항을 조사를 통해 사용경험 요소를 발굴하고 Navigation, Menu Hierarchy, Screen Layout 등의 설계를 통해 Prototype 개발을 하고 Usability Test를 통해 보완을 하였다. Usability Test는 한국, 미국, 영국, 중국 4개국에서 광범위한 사용자 조사가 이루어졌다. 국가 선정은 제품의 주요 시장 및 각 대륙을 대표하는 기준으로 선정되었다. 사용자 그룹은 연령, 지식 수준, 성별에 구분되었고 Web Survey 1000명, Usability Test는 각 국가별 총 100명이 넘는 참석자에 의한 데이터 분석이 이루어 졌다. 이렇게 조사된 데이터를 바탕으로 UI 사용경험 요소를 정의하고 제품의 공통 가이드와 개별 가이드를 개발하는 일련의 프로세스를 확립하고 검증하였다. 본 논문을 통해 대상 제품들의 다양한 특성을 살리면서도 user Interface의 일관성 원칙을 설립하기 위해 시도했던 방법과 과정을 기술하고, 이 과정을 통해서 얻은 결과와 실제적인 경험을 소개한다.

Emotional design gets more and more important. However, the systematical approaches to integration of user experience elements in product design have been rarely tried. This study consists of three parts. We extracted affective words fitting to design direction based on trend analysis. Then, user experience elements were matched with affective words. Finally, a prototype system was made to guide designing affective factors in electronic products. In the present study, user experience elements were defined as color, material & finishing, and sound. Through various documents analysis and trend analysis, trend analysis experts and user experience designers extracted 31 affective keywords which could fully reflect current trend. After paired-comparison of selected keywords, 2 sensibility dimensions were obtained by multidimensional scaling. Trend affective keywords could be explained by 2 dimensions of human-centered' vs. 'techno-centered' and 'warm vs. cool'. Next, user experience elements stimuli were matched with each keyword by user direct positioning on the 2 dimensions affective map. Based on the result of the experiment, the prototype system was developed for the product designers. The results of the current study could guide designers to design emotionally satisfactory products.

The purpose of this study is to analyze personalized contents and previews of OTT service based on user experience and to suggest the improvements of the preview viewing experience. Current domestic OTT mobile applications were researched to find out how services are offering content. Plus, the 20s-30s were recruited to analyze user experience. An online survey and in-depth interview were conducted by using Stephen P. Anderson's Creating Pleasurable Interface Model. As a result, preview help users to select content but it doesn't suit their taste. Also, the preview is hard to watch however they want. Therefore, it can be inferred that the preview requires the function for improving efficiency, preference, and accessibility. This study is expected to be used as research material on user experience or preview experience of OTT content.
