This study analyzed the effects of interactivity on the learning attitude in the tablet PC-based digital textbook environment. Most of digital textbook studies focused on comparison of learning effect between digital textbook and paper textbook. This study, instead, focused on the interaction between students and digital textbook, and examined the hypothesis that, in the digital textbook-based learning environment, interactivity factors affect learning attitude. The results showed that active control, two-way communication, and synchronicity have significant effects on the learning attitude. Those findings indicate that it's necessary to effectively realize interactivity in the process of developing digital textbooks. Also, important implication is not the fixed interactivity but how students perceive the digital textbook and make use of it. Therefore, for the interactive digital textbook, perceived user control, two-way communication, and synchronicity should be realized properly.

IT has been receiving increasing attention for cloud computing services. However, despite a lot of attention, there are limitations of existing research on cloud computing services. There are researches respectively about the benefits and costs that would occur if you choose a cloud computing services. However, in real life, consumers should be considered about the benefits and costs at the same time if they choose and use a cloud computing service. Therefore, this study examines the interaction effect of benefits and costs on cloud computing service. The findings demonstrate that three independent variables(usefulness, social influence, and innovativeness) positively(+) affect the perceived value. However, showed the benefits and costs of interaction effects analysis, usefulness and innovation on the cost influence the perceived value in statistics. The interaction of the usefulness & cost shows negative(-) effect and the interaction of the innovativeness & cost has positve(+) effect on the perceived value. In conclusion, this study provide that consumers need to consider costs with benefits when they use a cloud computing service.

This study aims to investigate how perceived interactivity between the mobile messenger application and its user gives rise to user's enjoyment and continuous usage intention. Perceived interactivity was assumed to be formed by the combination of control, share, and responsiveness in light of the previous studies. The relations between perceived interactivity, enjoyment, and usage intention are hypothesized on the basis of the pleasure-arousal-dominance emotional state model, the theory of reasoned action, and the theory of planned behavior. Survey data were collected from 481 mobile messenger users in Korea and China. In order to test hypotheses, structural equation modeling analyses were conducted. As a result, perceived interactivity concerning connectedness and responsiveness not only positively affected enjoyment, but also had a significant effect on usage intention. However, while control positively influenced usage intention, it was not significantly related to enjoyment. In addition, there was a positive relation between enjoyment and usage intention. Incidentally, multi-group analysis was conducted to explore the differences between Korean and Chinese users. The findings would provide managerial implications for mobile messenger corporations on causal effects of perceived interactivity and the differences of the path coefficients between in Korea and China.

This paper examines an augmented technology acceptance model, which includes perceived interaction as a mediator in the relationships between the technology acceptance model (perceived ease of use, perceived usefulness) and student satisfaction in online classes, and its impact on student satisfaction. Data has been collected from 842 undergraduate students in online universities. The data is analyzed by using factor analysis and structural equation modeling techniques. The results demonstrate that perceived ease of use, perceived usefulness, and perceived interaction serve as predictors for student satisfaction in online classes. Perceived usefulness has a positive relationship with perceived interaction while perceived ease of use has no effect on interaction.

애드혹 유비쿼터스 컴퓨팅 환경에서 상호작용 미들웨어는 컨텍스트의 변화에 따라 애플리케이션간의 상호작용을 재구성할 수 있도록 지원해야 한다. 또한 미들웨어는 컨텍스트 인지 상호작용을 지원하는데 있어 컨텍스트 종류나 애플리케이션들 혹은 환경의 다양성에 따라 컨텍스트 변화에 대한 적응성을 동적으로 변화시킬 수 있도록 기능을 제공해야 한다. 하지만 기존 연구들은 컨텍스트 변화에 대한 적응성을 변화시키는 이러한 요소들에 대해 고려하지 않으며 그로 인해 컨텍스트 변화에 대한 적응 정도를 정적으로 설정함으로써 컨텍스트 인지 상호작용을 지원하는데 있어 경우에 따라 오버헤드가 발생하거나 컨텍스트 변화에 빠르게 대응하지 못한다. 따라서 본 연구는 애드혹 유비쿼터스 컴퓨팅 환경에서 동작하는 Publish/Subscribe 기반의 상호작용 미들웨어에서 이벤트 중계의 정확성과 컨텍스트 변화 적응성간의 관계를 기반으로 다양한 컨텍스트 종류나 사용자, 환경에 따라 이벤트 중계의 정확도를 동적으로 조절하는 기법을 제안한다. 그리고 이를 기반으로 이벤트 중계 정보를 동적으로 재구성하여 컨텍스트에 맞춰 효율적으로 컨텍스트 인지 상호작용을 구성할 수 있는 기법을 제안한다. 비교 분석 결과 기존 연구에 비해 컨텍스트 변화에 대한 적응성에서 더 나은 결과를 보여주었다.

In this study, we experimented with experience of digital signage using Virtual Reality technology, and the difference between presence and interactivity in brand experience and digital signage attitude. We conducted a two-way MANOVA analysis with cognitive presence, emotional presence, and media presence as the independent variable and interactivity level(high vs low) as dependent variables and the brand experience and attitude as dependent variables. First, cognitive presence was found to be most effective through behavioral experience when low interactivity. Second, emotional presence also has a positive effect on emotional experience when the level of interactivity is low. Third, media presence has a positive effect on emotional experience if the level of interactivity is low. This study suggests a communication strategy to communicate presence according to the characteristics of media strategy and technology through appropriate level of interactivity when using digital technology. Future research requires a qualitative approach rather than a quantitative one in terms of interactivity.

This study explores the effects of advertising's interactivity on consumers' attitude, brand awareness, intention of word-of-mouth and purchase intention through a comparison between high interactive advertising and low interactive advertising. Experiment was carried out with two factorial design using high and low interactive advertising messages and two different countries. The respondents were 120 Korean and 120 Two hundreds forty valid questionnaires were collected. According to the research results, the brand awareness and attitude of high interactive advertising is much higher than the low one to the consumers of Korean and Chinese. The consumers of Korean and Chinese who were exposed to high interactive advertising have high intention to word-of-mouth in high interactive advertising. Korean and Chinese consumers also have high intention to purchase when they watch the high interactive advertising. Between two countries, Chinese consumers have higher intention to purchase than Korean consumers.

I guess that e-learning buying behaviors have some selection criteria which are interactivity, contents quality, perceived usefulness, and corporate reputation. And I propose that the effects of selection criteria on adaptation intention are moderated by buyer-user status. To accomplish research purpose, I conducted a field survey with a self-administered questionnaire in both user-buyer and analysed the causal relations among the variables by regression analysis. Findings are these. In all of the customer, interactivity, perceived usefulness, and corporate reputation had positive effects on re-attending intention to another e-learning class. In case of users(students), interactivity, contents quality, and perceived usefulness had positive effects, but buyer(parents) showed both perceived usefulness and corporate reputation had positive effects on re-attending intention.

Recently, virtual reality and augmented reality technology have been extensively utilized in brand communication. The purpose of this study is to investigate digital reality contents as branded entertainment and content-analyze its format and contents for brand communication. Coding categories were derived to examine marketing characteristics of 300 digital reality contents and key descriptive statistics were presented and interpreted. The results revealed that consumer responses(i.e., view count, like, and dislike) toward Branded Digital Reality contents vary according to types of storytelling. Moreover, perceived values of contents also varied by the types of digital reality(VR vs. AR). Based on the results, this paper discusses the academical and managerial implications of study findings.
