| Summary: | This study’s purpose was to establish a predictive model of the intention to accept Taekwondo electronic protector devices through the application of the technology acceptance model. Two hundred and twenty collegiate Taekwondo practitioners affiliated with the Korea Taekwondo Association participated in a survey that included 28 questions (4 relating to demographic characteristics, 12 to precursor variables, and 12 to the technology acceptance model). Correlation and structural equation modeling analyses were applied and a significance level of 0.05 was used. The results were as follows. Perceived quality had a significant influence on perceived ease of use (<i>β </i>= 0.380, <i>t</i> = 3.481, <i>p</i> < 0.001) and perceived usefulness (<i>β </i>= 0.544, <i>t </i>= 5.098, <i>p </i>< 0.001). Visual attractiveness had no significant influence on either perceived ease of use (<i>β </i>= 0.159, <i>t </i>= 1.798, <i>p </i>= 0.072) or perceived usefulness (<i>β </i>= −0.010, <i>t </i>= −0.131, <i>p </i>= 0.896). Wearability had a significant influence on perceived ease of use (<i>β </i>= 0.234, <i>t </i>= 2.867, <i>p </i>< 0.01), but a significantly negative influence on perceived usefulness (<i>β </i>= −0.218, <i>t </i>= −2.932, <i>p </i>< 0.01). Functionality had no significant influence on either perceived ease of use (<i>β </i>= 0.116, <i>t </i>= 1.031, <i>p </i>= 0.302) or perceived usefulness (<i>β </i>= 0.107, <i>t </i>= 1.093, <i>p </i>= 0.274). Perceived ease of use had a significant influence on perceived usefulness (<i>β </i>= 0.418, <i>t </i>= 4.361, <i>p </i>< 0.001) and acceptance intention (<i>β </i>= 0.361, <i>t </i>= 4.031, <i>p </i>< 0.001). Perceived usefulness had a significant influence on acceptance intention (<i>β </i>= 0.525, <i>t </i>= 5.758, <i>p </i>< 0.001). These results suggest that improving the perceived quality and wearability of the devices will enhance their acceptance. We believe that this study provides an appropriate verification model for the intention to accept Taekwondo electronic protection devices.
