In this paper, we investigated the factors affecting the intention to use smartphone banking with a research model based on the Technology Acceptance Model (TAM) extended to include security risk, trust, and self-efficacy. With analysis after controlling factors such as age, gender, and previous experience of smartphone banking that may have effects, we conclude that perceived usefulness, perceived ease of use, security risk, and trust have direct effect on the intention to use smartphone banking, and self-efficacy has indirect effect on the intention to use through mediation of perceived ease of use. We performed a study to check the validity of TAM in the context of smartphone banking, and confirmed that perceived ease of use has both direct and indirect effect on the intention to use.

As a single-person household emerges as an important consumer group, an Online-to-Offline or Offlineto-Online(O2O) service market is rapidly growing. This study attempted to verify the effects of convenience and webrooming characteristics of O2O service using the Technology Acceptance Model (TAM). The purpose of this study was to investigate the effects of the convenience and webrooming of food O2O service on users' perceived ease of use and perceived usefulness, and the effects of perceived ease of use and perceived usefulness on purchase intention of O2O services. Using a convenience sampling technique, an online survey was conducted through Google survey from April 16 to April 30, 2017 and was distributed to 447 O2O service users. A total of 320 questionnaires were included in the final analysis. The results showed that convenience had a significant effect on users' perceived ease of use as well as perceived usefulness. In addition, users' perceived ease of use had a significant impact on users' perceived usefulness. Finally, both perceived ease of use and perceived usefulness positively affected users' purchase intention of O2O services. These findings suggest that differentiated events, promotions, and store information should be provided when launching O2O service because webrooming is a more important factor in enhancing perceived usefulness than the perceived ease of use.

This study looks deep into how user's individual personality and his or her media experiences affect perceived usefulness and perceived ease of use about UHDTV based on Technology Acceptance Model using survey methodology. This study also focuses on how the purchase intention of terminal equipments and the willingness to pay for UHD contents will make different choices. The result of this study shows that, whether user is an exhibitionist or not or has frequently encountered a big screen, these factors affect both the perceived usefulness and the perceived ease of use about UHDTV. When user is an exhibitionist with more experience with big screens, it was clear that user tended to choose UHDTV with higher perception of usefulness and ease of use about UHDTV. This study also implies that when supplying the next generation broadcasting service, it is needed to consider the users' perceived usefulness and ease of use about UHD as well as the individuals' media experiences and characteristics.

There is a need for research to identify the integrated, rather than fragmented, factors that determine users' acceptance of Internet shopping. Using the newly revised technology acceptance model (TAM) as a theoretical framework, this study investigates the effect of a set of information systems quality (information quality and system quality) and trust on intention to use Internet showing through perceived ease of use and perceived usefulness. Using structural equation modeling, the results strongly support the utilization of TAM in predicting users' intention to use Internet shopping, and demonstrates the effects of critical external variables on behavior intention through perceived ease of use and perceived usefulness. Systems quality such as response time, accessibility, and usability has significant effects on perceived ease of use of Internet shopping. Futhermore, trust has also a significant effect on perceived usefulness, perceived ease of use, intention to use Internet shopping, and actual usage of Internet shopping. Based on these results, this study suggests managerial implications of new Internet shopping strategies, focusing on the integration of information systems quality and trust in order to achieve sustainable competitive advantage in Internet shopping.

The use of global mobile technology has increased exponentially. In particular, a survey of consumers in the Philippines showed that 83% "could not live" without their mobile phones. We investigated factors, such as ease of use and personal innovativeness, to elucidate the consumer adoption of mobile technologies in the Philippines, to integrate existing adoption theories for academics and provide recommendations to practitioners based on our findings. Our research questions are as follows: (1) What key factors drive adoption of mobile technologies by Filipino consumers?; (2) Are Filipino consumers innovative in their use of mobile technologies?; And (3) How can telecom companies retain their customers? A structural equation model, which was built from a survey of 528 mobile Filipino consumers, showed support for repurchase intention to use mobile technologies. The hypotheses were generally supported by variables related to mobile phone usage with the Philippine consumer sample. Results support all of the hypothesized relationships for consumers using mobile technologies. Personal innovativeness did load on both attitude and repurchase intention for mobile applications as originally hypothesized but was strongly loaded for attitude toward using. This research is a first step in understanding the adoption of mobile applications by Filipino consumers. We initially hypothesized that consumer behavior toward mobile applications would involve constructs of innovativeness, ease of use, and satisfaction; however, we found that ease of use was less significant in understanding repurchase intention to use mobile technologies. Personal innovativeness was more important in explaining satisfaction with mobile application attitudes and repurchase intention. The Filipino context of this study also provides other interesting implications. As the Philippines transitions into a more international market, western products start to guide market behavior, particularly consumer adoption.

Recently, firms which have offered a "free Internet service" to their customers, are considering a "charged Internet service" for increasing a company's profit. But they have doubts about the results, because consumers may fly away from their web-site easily and may discontinue using their services. The purpose of this study is to investigate which factors make consumers use the charged Internet services. To do this, the factors, which are ease of using the service, usefulness of the service, the reputation of the service provider, service cost, and the intention to use the service as a mediator, are analyzed. To achieve this research objective, a structural equation model was constructed and a field study method was used. The findings are summarized as follows: First, ease of using the service, usefulness of the service, and service cost have significant impacts on the charged Internet service usage through the intention to use. Especially, although service cost influences on the service usage largely, the usefulness of the service has a bigger impact on the charged Internet service usage than service cost. Second, the reputation of the service provider does not have any impact on the service usage. Third, consumers using only the free Internet service tend to hesitate about using the "charged Internet service" because they doubt its ease of use and usefulness in spite of the service cost.

This study was conducted to explain airport users' acceptance intention for untact smart devices being introduced at Incheon Airport. Based on the technology acceptance model, perceived usefulness and ease of use influenced attitudes and intention to use. It was verified whether it was affecting the effect. In addition, variables proposed in innovation diffusion theory were selected to verify exogenous variables that affect perceived usefulness and ease of use, which serve as key independent variables in the technology acceptance model. Research results show that perceived usefulness has a high level of positive influence on attitude, whereas perceived ease of use has a low influence and does not show a statistically significant influence. In addition, it was confirmed that most variables of the innovation diffusion theory had no effect on usefulness and ease of use. This means that the key variable in the spread and use of untact smart devices at airports is the perception of usefulness, which means that resistance to accepting new technology is not high.

This study empirically analyzed the effects of immersion and self-efficacy on the intention to continuously use realistic media. To this end, we used an extended technology acceptance model that includes not only the perceived ease of use and usefulness, but also the perceived joy as important factors. We collected data from 595 participants through an online questionnaire survey and tested the research model using a covariance-based SEM. As a result, we found that a user's immersion significantly increased perceived usefulness, ease of use, and joy of realistic media; and self-efficacy increased perceived usefulness and ease of use. Although the effect of perceived usefulness was relatively stronger than that of perceived joy, we found that the effect of perceived joy on the intention to use was also quite large. The effect of perceived ease of use on intention to use was found to be completely mediated by perceived usefulness and joy. In addition, the differences according to the types of media were tested by comparing two groups: augmented reality and virtual reality. The effects of perceived ease, usefulness, and joy on the intention to use were very similar regardless of the type of immersive media. However, it was found that self-efficacy increases usefulness only in augmented reality. Based on our findings, we have discussed the implications of our study, as well as the scope for future research.
