Service providers have introduced interactive devices such as self-service kiosks to provide convenient and efficient services to consumers. Self-service kiosks are one of the most diverse technological forms of self-service technologies that provide control and freedom to consumers as well as reduce the frustration of line-ups. This study explores the predictors of consumer resistance and continued use intention with regard to self-service kiosks. It adopts three constructs on the following variables: perceived innovation characteristics, consumer characteristics, and gamification. An online self-administered survey was conducted, and 343 users of self-service kiosk services, aged between 20 and 59, were included in the analysis. The study used the SPSS 23.0 program to perform a descriptive analysis along with, t-test, ANOVA, correlation analysis, and regression analysis. First, convenience, controllability, and gamification negatively influenced consumer resistance to self-service kiosks. Second, human alienation and sociability positively influenced consumer resistance to self-service kiosks. Third, convenience and gamification positively influenced the continued use intention with regard to self-service kiosks. Last, the risk of functionality, human alienation, and sociability negatively influenced continued use intention with regard to self-service kiosks. The results contribute to the literature because few studies have examined what drives the resistance of users and continued use intention with regard to self-service kiosks. It also provides service providers and practitioners with insights and strategies on how to overcome consumer resistance.

The purpose of this study is to examine factors affecting the diffusion and the intention to use, and how these factors differ among adopter categories. A survey was done to analyze the diffusion of smart-phone, the most popular and innovative product nowdays. We collected 197 survey questionnaires from smart-phone user and analyzed the data using SPSS 18.0 and Smart PLS 2.0. PLS (Partial Least Square) analysis was implemented before multiple group-innovator, early adopter, eraly majority- analysis which is categoriezed by Innovation Diffusion Model of Rogers (1995). The results show that firstly, in innovator group (n=63), the functional and the safety value have significantly positive effect on user satisfaction. In addition, we found that user satisfaction and the brand loyalty are significatly associated with the intention of use. Secondly, in early adopter group (n = 67), the design value has significantly positive effect on user satisfaction and it has significantly positive effect on brand loyalty. Finally, in early majority group (n = 67), the design value has significantly positive effect on the user satisfaction and it has stronger effect on the intention of use and brand loyalty. We conclude this paper with the implication of this study to both academia, business practice, and policy making.

This study aims to predict causal relationships between experience economy, perceived flow, and continuous use intention in the mixed reality (MR) environment. A virtual fitting mirror with two modes (i.e., avatar and self-image) was selected for this study. A total of 200 samples was obtained in two sample frames: virtual fitting users in avatar mode (group 1, n = 119) and self-image mode (group 2, n = 81). The results showed that the experience economy consists of entertainment, education, esthetic, and escapism. The entertainment and esthetic experiences had positive effects on perceived flow, leading to continuous use intentions. For avatar mode, the entertainment and esthetic experiences had positive effects on continuous use intentions through the mediating effect of flow; and the education experience had a positive effect on the continuous intentions to use the MR technology. For self-image mode, the flow mediated the effect of entertainment on continuous use intentions, whereas education and escapism directly affected the intention to use the MR technology. The paper also discusses the theoretical and managerial implications of using MR technologies in fashion retailing.
