A Research on the Usability Evaluation of Telecommunication and Navigation Applications in In-Vehicle Infotainment Systems

Due to the continuous growth in global trends favoring the development of new energy sources, the in-vehicle infotainment systems (IVIS) domain has witnessed considerable expansion. However, evaluations of in-vehicle activities by national institution have revealed significant safety concerns regarding the utilization of IVIS for telecommunication and navigation during driving. Consequently, this research aims to conduct usability assessments on two widely adopted IVIS platforms, referred to as Sample A (Android Auto) and Sample B (Apple Carplay). A total of thirty-one participants will be recruited to engage in real-world interactions, undertaking context-driven tasks utilizing navigation and telecommunication applications. Objective data, encompassing performance metrics (subjected to two-way ANOV A), alongside subjective feedback (elicited through System Usability Scale questionnaires and semi-structured interviews), will be gathered to explore participants' and users' preferences. Ultimately, the comprehensive analysis of both datasets and perspectives is anticipated to reveal Sample A's superior overall performance compared to Sample B. Additionally, participants have provided valuable insights into the desired attributes of novel IVIS and their applications, including variability in visual presentation, customizable layouts, and simplified navigation with expanded touch range. In conclusion, this research conducted a usability evaluation of two IVIS systems and anticipates broader domain expansion in subsequent related studies.
