The purpose of this study is to verify the relationship between perceived innovation and use motivation, use motivation and continuous use intention of fast food restaurants, and the moderating effect of reliability. As for the sample, a total of 317 customers who visited fast food restaurants were used for the final analysis, and the hypothesis verification results are as follows. First, the perceived innovation of Hypothesis 1 was found to have a positive (+) significant effect on the motivation for use (entertainment motivation, performance expectation, habit). Second, it was found that the motivation for using Hypothesis 2 (entertainment motivation, performance expectation, and habit) had a positive (+) significant effect on the intention to continue using. Third, as a result of the moderating effect of reliability on the influence relationship between perceived innovation and use motivation in Hypothesis 3, the high group showed the moderating effect of reliability on the influence relationship between perceived innovation, entertainment motivation, and performance expectations. In the low group, the moderating effect of reliability was confirmed on the influence relationship between perceived innovation and entertainment motivation. Fourth, as a result of the moderating effect of reliability on the relationship between the motivation for use and the intention to continue using Hypothesis 4, the high group showed a moderating effect of reliability in all factors. In the low group, the moderating effect of reliability was confirmed on the influence relationship between entertainment motivation and continuous use intention. As a result of the above, it is necessary to increase the emotional value of kiosk products for new virtual spaces, apply an error prevention interface, and create an environment for products that are reliable and reliable for fun and interest in technology.
