Continuous Usage Intention of In-Vehicle Infotainment Systems: An Integrated ECM-TAM Approach

Year: 2026

Type: preprint

Abstract: In-vehicle infotainment systems (IVIS) differ from static information systems due to complexity, safety-critical nature, and over-the-air (OTA) evolution. While initial adoption is well known, the driving forces of continuous intention to use (CITU) are still poorly studied. Integrating the Expectation-Confirmation Model (ECM) and Technology Acceptance Model (TAM), this study explored how intrinsic motivations—perceived security (PS), perceived usefulness (PU), perceived ease of use (PEU), and perceived enjoyment (PE)—interact with external factors, including system & service quality (SSQ), confirmation (CON), and satisfaction (SAT), to influence CITU. 516 Chinese users were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). Results showed that the framework was powerfully explanatory. PS emerged as the main driving force of CITU, surpassing PU and PE, underscoring the criticality of risk aversion in smart mobility. SSQ and PU are identified as primary antecedents of SAT. Mediation showed that CON affects CITU via multiple paths, and the functional route (CON → PEU → SAT → CITU) is the strongest influenced. These results suggest that while OTA updates change user expectations, long-term engagement depends on security and utility against hedonic experiences.
