The widespread use of smart phones and smart pads has given rise to the use of eBook services based on these smart devices. Consequently, the size of eBook services has exploded both in the domestic as well as overseas market. However, the growth curve becomes flatter than before, and the adoption rate is still not high in Korea. Hence, this study explores the factors affecting the intention to use eBook services based on smart devices, and their relationships. Finally, we propose an eBook adoption model, which extends the Technology Adoption Model. An online survey was conducted to validate the research model. By applying Partial Least Squares, we found that there are strong relationships among perceived usefulness, perceived ease of use, perceived playfulness, social influence, and intention to use. In addition, we found that smart devices enjoyment positively affects the perceived playfulness of eBooks, and that personal innovativeness positively affects perceived ease of use. Our findings shed some light on how to design eBook services based on smart devices.

Generative AI services, including ChatGPT, were becoming increasingly active. This study aimed to empirically analyze the factors that promoted and hindered the diffusion of such services from a consumer perspective. Accordingly, a research model was developed based on the Value-based Adoption Model (VAM) framework, addressing both benefit and sacrifice factors. Benefits identified included usefulness and enjoyment, while sacrifices were security and hallucination. The study analyzed how these factors affected the intention to use generative AI services. A survey was conducted among college students for empirical analysis, and 200 valid responses were analyzed. The analysis utilized structural equation modeling with AMOS 24. The empirical results showed that usefulness and enjoyment had a significant positive impact on perceived value, while security and hallucination had a significant negative impact. The order of influence on perceived value was usefulness, hallucination, security, and then enjoyment. Perceived value had a significant positive impact on usage intention. Moreover, perceived value was found to mediate the relationship between usefulness, enjoyment, security, hallucination, and the intention to use generative AI services. These findings expanded the research horizon academically by validating the effectiveness of generative AI services based on existing models and demonstrated the continued importance of usefulness in a practical context.

This study aimed at investigating the features of m-commerce (mobility, perceived enjoyment, perceived personalization, and habit) that influence consumers' behavioral intents to adopt mobile shopping. To this end, it theorized on and examined the effects of the features of m-commerce that influence consumers' behavioral intents to adopt mobile shopping. The results showed that the most critical drives of m-commerce in mobile shopping are mobility, perceived personalization, and habit. And also we found that habit weakens (moderates) the effects of mobility on the consumers' behavioral intents to adopt mobile shopping. Habit has direct effects on the consumers' behavioral intents to adopt mobile shopping, and these effects are moderated by individual habit.

Social commerce is a combination of social media and shopping. Social commerce, based on Web 2.0 technologies, has the various potentials, which is the factor attracting customers. In Korea, collegians are more active user of social media, in turn, are estimated more active customer in social commerce context. Present research explored what made Korean collegians use social commerce with extending technology acceptance model(TAM) with word-of-mouth(WOM) and perceived enjoyment(PE). We found that WOM affected indirectly the intention to use(ITU) with mediating PE, in turn, PE has a positive effect on the all of constructs in TAM. Accordingly, TAM extended with WOM and PE is validated in social commerce context. Finally, based on the findings, implications and suggestions for future studies are discussed.

Digital signage in a smart store would engage and invoke responses from consumers because good in-store experiences are more important than ever. Thus, the present study investigates consumer perceptions of interactive digital signage integrating technology acceptance model. Specifically, the current study examined 1) the effects of personal and fashion innovativeness on interactivity; 2) the effect of interactivity on perceived usefulness, ease of use, and enjoyment; and 3) the effects of perceived usefulness, ease of use, and enjoyment on intentions to use the products and the store, visit the store, and engage in word-of-mouth. As a pre-study, two researchers visited the smart stores of six brands in Seoul, all of which integrate various technologies in the fashion field. A video clip was developed as a stimulus to the study. A total of 214 responses were gathered and analyzed. The results were as follows. Personal innovativeness has a significantly positive effect on interactivity, whereas fashion innovativeness has no significant effect. Interactivity had positive effects on the perceived usefulness, ease of use, and enjoyment. Consumer responses (i.e., intentions to use, visit, and engage in word-of-mouth) were predicted by usefulness and enjoyment, but not by ease of use. The findings of this study could provide the fashion industry and retailers practical and valuable insights into enhancing consumers' in-store experiences through the use of interactive digital signage.

The main attractant of portable multimedia player(PMP), is often their versatility : being able to load and play different formats of video, audio, digital images, and interactive media. In this paper, we investigate the factors influencing the usage the PMP, based on the extended version of the Technology Acceptance Model. Using the data collected from online survey, we show that perceived usefulness, perceived ease of use, and perceived enjoyment are the major determinants for using PMP. Factors, including ubiquitousness, community, and image are shown to directly or indirectly determine the level of perceived usefulness and ease of uses. In addition, we classify PMP users into two groups, users seeking hedonic value and utilitarian value, and examine the differences in path coefficients. Properties of the causal paths, including standardized path coefficients, the significance of difference, in the hypothesized model, are also presented, so that we can investigate the relative influences of different dominants, demonstrating how two groups differ in their decision-making processes regarding the PMP usage.
