ABSTRACT
In the wave of Industry 4.0, GPS sports watches are redeveloping towards digitization and intelligence. Whether the information is correct and real-time, operation interfaces easy to use and the displayed information easy to understand have become issues that consumers and manufacturers emphasize. Thus, this study investigated the effects of output quality and result demonstrability on the perceived usefulness of GPS sports watches with participants of the 2020 Taiwan International Triathlons as the research subjects. In total, 280 respondents, who participated in the 2020 Taiwan International Triathlon, were selected by purposive sampling for a questionnaire survey. The statistical software SPSS was employed to file the data, and the statistical software of AMOS was adopted to analyze the correlation among variables. According to the results, (1) output quality has significantly positive effects on perceived usefulness;(2) result demonstrability has significantly positive effects on perceived usefulness;(3) perceived ease of use has significantly positive effects on perceived usefulness;(4) perceived ease of use has significantly positive effects on behavioral intention to use;and (5) perceived usefulness has significantly positive effects on behavioral intention to use.
