In this study, the objective was to understand the receptivity to wearable devices in Portugal and Brazil, analyzing factors such as demographic characteristics, technological experiences and personal opinions. To achieve this, we adapted the Unified Technology Acceptance and Use Model 2 (UTAUT2) model and collected responses from university students and frequent internet users using a Likert scale questionnaire. Data analysis revealed a majority of Portuguese participants and a stronger trend of acceptance among the youngest, most educated and those with the greatest affinity with technology, especially men. The proportion of users and non-users of wearables was balanced, with greater acceptance among individuals aged 35 to 59, women and those with a positive attitude towards technology. Surprisingly, social influence did not prove to be as decisive in the acceptance of wearables as initially assumed. The results indicate a growing preference for the adoption of these devices, but also point to challenges related to the perceived value and, consequently, the cost of the products, which suggests a promising terrain for future research and technological advances.
