As of 2022, the 50s and 60s accounted for 30% of Korea's total population. Looking at the characteristics of the 5060 generation can yield strategic implications for purchasing power in the wearable device market as well as understanding 5060 generation consumers. As a result, this study investigates the factors influencing wearable device acceptance, taking into account the market potential of the 50s and 60s. Clustering analysis was conducted for 50s and 60s households based on four factors of technology readiness: innovation, positivity, anxiety, and discomfort. An analysis was conducted on 283 participants corresponding to 50s and 60s households, and demographic analysis, hierarchical regression analysis, clustering analysis, chi-square analysis, and one-way ANOVA were conducted through SPSS 26.0. As a result of regression analysis, innovation and optimism had a significant effect on the acceptance of wearable devices in 50s and 60s. Also, based on a cluster analysis, the 50s and 60s were divided into a total of four segment: such as the positive group, the insensitive group, the ultra-sensitive group, and the negative group. The ultra-sensitive group was the most active in acceptance of wearable devices, and the negative group was the most negative for acceptance.
