EXPLORING CREDIBILITY IN TECHNOLOGY ACCEPTANCE: A STUDY OF RADAR SENSORS FOR HEALTH MONITORING IN BINH DUONG SMART CITY, VIETNAM

Abstract

As Smart Cities continue to evolve, the integration of advanced technologies is crucial for enhancing urban living standards and optimizing city management. Non-invasive monitoring devices like radar sensors hold significant potential for providing real-time, contactless health monitoring, offering a feasible solution for improving public health in densely populated urban areas. This study explores the factors that influence the acceptance and intention to use radar sensors for health monitoring, with a specific focus on Perceived Credibility (PC) within the framework of the Technology Acceptance Model (TAM). A survey conducted among 222 participants who are living or working in Binh Duong Smart City examined the relationships between Perceived Ease of Use (PEOU), Perceived Usefulness (PU), PC, Attitude Toward Use (ATU), and Intention to Use (ITU) using Structural Equation Modeling (SEM). The results revealed that PC significantly impacts PU (β=5.062, p<0.001), while PEOU positively impacts PU (β=5.687, p<0.001), and ATU (β=3.150, p=0.002). These findings suggest that ease of use not only increases perceived benefits but also improves user attitudes. Additionally, PU strongly predicts ATU (β=6.000, p<0.001), and ATU is a key determinant of ITU (β=32.297, p<0.001), highlighting the crucial role of positive attitudes in driving adoption. These insights underscore the importance of trust in technology, ease of use, and perceived usefulness in shaping positive attitudes and facilitating the adoption of radar sensors. By enhancing perceived credibility, city planners and technology developers can effectively integrate these devices into Binh Duong Smart City’s infrastructure, thus improving urban health outcomes and supporting the city’s vision of becoming a leading smart urban environment.
