Whereas traditional user interface are well accepted modes of information exchange, the new digital conversion type's of information media is relatively complex and provides new means of transaction with user interface. User interface can be decomposed into two component: the physical structure through which information media is controlled, and the presentation of the content. This research explores the two user interface element have different effect on the adoption of information media and, as such, can influence perceived usefulness, perceived easy of use, and intention of use. The hypotheses have been tested with the survey of 148 end-users examines two interface characteristics factors such as efficiency, error, design, entertainment, accuracy, and vividness, and so on. The research summarized in this paper decomposes the influence of interface elements of physical structure interface and content presentation interface to gain a better understanding of how interface stimulates user's perceived usefulness to adopt the information media.

Recently, as personal information utilization devices such as IoT, artificial intelligence, and wearable devices that focus on the individual have spread, privacy violations are also increasing. However, the privacy paradox of providing personal information to enjoy services while worrying is getting stronger. However, there are still preliminary studies on this. In this study, an intelligent home camera based on IoT technology was selected as a research object, and whether privacy paradox exists in the IoT environment, including smart home camera, was studied. To this end, the effect of perceived usefulness, a benefit factor of smart home camera use, and privacy concern, a risk factor, on intention to use was verified. In addition, it was investigated whether the relationship between privacy concerns and intention to use differs according to the presence or absence of use experience. In order to verify the research model, a survey was conducted with people with and without experience in using smart home cameras, and a total of 298 data samples were used for statistical analysis. As a result of the analysis, it was found that both perceived usefulness and privacy concerns had a positive effect on the intention to use, proving that privacy paradox exists in the IoT-based smart home camera environment. In addition, by analyzing the fact that privacy concerns have different effects on usage intentions depending on the user experience, it was verified that those with experience have a strong privacy paradox and those without experience have a weak privacy paradox. This study is meaningful because it seeks strategic implications to improve service and business performance by understanding the relationship between privacy attitudes and behaviors of IoT service providers, including smart home cameras.

The purpose of this study is to find an answer why internet users are unconcern about their privacy information. We found that perceived privacy risk and website usability have a significant effect on privacy unconcern. That is, individuals who have experiences privacy incidents are more likely to be unconcern about their privacy information. Accordingly, organizations who supply services on the web have to pay more attention to these individuals to increase a privacy concern. Implications and Conclusions are discussed.

This study sought to design and develop an interactive video player (IVP) capable of promoting student engagement through the use of online video content. We designed features built upon interactive, constructive, active, passive (ICAP), and crowd learning frameworks. In the development stage of this study, we integrated numerous interactive features into the IVP intended to help learners shift from passive to interactive learning activities. We then explored the effectiveness and usability of the developed IVP by conducting an experiment in which we evaluated students' exam scores after using either our IVP or a conventional video player. There were 158 college students who participated in the study; 76 students in the treatment group used the IVP and 82 students in the control group used a conventional video player. Results indicate that the participants in the experiment group demonstrated better achievement than the participants in the control group. We further discuss the implications of this study based on an additional survey that was administered to disclose how usable the participants perceived the IVP to be.

The mouse as an input device has undoubtedly brought convenience to users due to its intuitiveness and simplicity, but it also brought unprecedented issues such as carpal tunnel syndrome (CTS). As a result, the necessity of alternative input devices that put less strain on the wrist, while still providing the convenience of a conventional mouse, has emerged. Unfortunately, there have been several research about alternative devices to replace a mouse, however, they showed inconsistent results. This study suggests that those inconsistent results may stem from the type and the difficulty of tasks used in previous studies. Therefore, we designed this study to compare the performance and perceived workload of three input devices (Mouse/Trackball/Touchpad) in each condition in terms of task type (Targeting/Tracking) and difficulty level (Easy/Hard). The results indicated that there were significant performance differences and no significant workload differences among the three devices, and the interactions were observed in some conditions. These results can provide users with practical guidelines to choose the optimal input device according to their needs or purpose.

Purpose The sharing economy is the most important keyword that is changing the paradigm of the world economy and management, and it was selected as one of 10 ideas to change the world in 2011 in Time magazine. The purpose of this study is to verify the structural relationship between perceived value and risk, network effect, usefulness, trust, and intention to use of accommodation service. In addition, the effects of utility and trust, and the experience of using accommodation service are controlled by the effect of empirical value and reciprocal value among the perceived value of sharing economic service, The purpose of this study is to propose a plan to activate the accommodation sharing service. Design/methodology/approach This study was designed to investigate the structural relationship between perceived value, perceived risk, network effect, usefulness, trust, and intention to use. Empirical analysis was done using SPSS 21.0 and AMOS 21.0 Findings Based on the results of this study, the following conclusions can be drawn. First, it was concluded that the higher the economic value of the accommodation sharing service is, the more useful and reliable the service is. Second, the higher the experiential value of the accommodation sharing service is, the higher the usefulness and reliability of the service are. Third, it was concluded that the higher the value of the mutual benefit of the accommodation sharing service is, the higher the trust level of the service is, but not the usefulness of the service. Fourth, it was concluded that the higher the perceived risk of accommodation sharing service is, the lower the service trust level is, but the service usability is not affected. Fifth, it was concluded that the larger the network effect of the accommodation sharing service is, the more useful the service is, but it does not affect the reliability of the service. Sixth, it was concluded that the higher the overall reliability of the accommodation sharing service is, the higher the usefulness of the service is. Seventh, it was concluded that the higher the overall usefulness and reliability of the accommodation sharing service are, the higher the intention to use the sharing service is. Finally, in order to test the effect of the experience on the use of trust and usefulness of the accommodation sharing service, multiple group analysis was conducted to examine the relationship between trust and usefulness, It is shown that there is a moderating effect in the path.

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.

사용성의 주관적인 판단기준으로써 재미(Fun)라는 요소는 사용성 지각에 있어 중요한 역할을 할 수 있다는 논의는 제기된 반면 개념자체의 모호성과 객관적인 측정의 어려움으로 인해 실증적인 연구가 많이 이루어지지 못했다. 재미와 관련된 기존의 연구들은 시각적인 요인에만 국한되었다. Shneiderman(2004)은 재미를 설계하기 위한 5가지 fun-feature 중 하나로 만족스러운 소리(satisfying sound)를 제시하였는데, 시각적인 요인 못지않게 청각적인 요소는 인간-컴퓨터 상호작용에서 사용자에게 과제를 적절하게 수행해나가고 있는지에 대한 하나의 피드백으로도 작용할 수 있고, 즐거움을 줄 수 있다. 본 연구에서는 승차권 자동발매기를 중심으로 소리의 유무와 소리의 재미수준이 사용성에 어떤 영향을 미치는지 알아보고자 소리가 없는 조건, 재미없는 소리 조건, 재미있는 소리 조건에 따라 사용성을 다르게 지각할 것이라고 가정하였다. 또한 모형의 사용성 수준이 매개 변인으로 작용할 수 있다고 보고 사용하기 좋은 모형과 좋지 않은 모형 두 가지를 제시하였다. 참가자들은 두 가지 모형에 대해 각각의 소리조건에 따라 과제를 수행하고 모형과 소리 조건에 대해 집단 면접을 실시하였다. 실험 결과 재미있는 소리조건에서는 정답률이 다른 소리 조건들에 비해 더 높았으며 총클릭수는 더 적었다. 면접 결과에서는 좋지 않은 모형에 재미있는 소리는 긍정적으로 인식되지 않음을 발견하였다. 이는 Davis(1992)가 사용성이 뒷받침 되지 않은 상황에서 재미는 긍정적인 요인으로 작용하지 않는다는 주장을 지지한다. 본 연구는 재미의 한 구성 요소인 소리를 통해서 사용성에 있어 재미가 중요한 역할을 할 수 있다는 것과 사용성을 전제하지 않은 것에 있어 재미요소의 적용은 부정적으로 인식될 수 있다는 점을 제안하였다.

This study describes a set of user experience indicators developed for the evaluation of knowledge and information resource systems. The user experience perspectives had emerged as a new analysis standard in the field of information media and information service research. The study included a survey conducted to verify the derived experience factors and developed them as indicators. The survey data was gathered from 158 participants in the preliminary and 480 participants in the main study. The applied analysis techniques were descriptive statistics, the exploratory factor analysis, the confirmatory factor analysis, the correlation analysis, and the path analysis. The results introduced seven user experience factors, 37 detailed user experience factors, and 105 system perception factors as the final user experience indicators. The developed and verified indicators should measure the degree of user experience perceived by users of the knowledge and information resource system and conduct effective evaluations that reflect correlation rather than a simple comparison of each experience factor.
