Abstract
In the field of Semi-Autonomous Vehicles (SAVs), or partially automated vehicles, ensuring that drivers can better understand and respond to Take Over Requests (TORs) is essential for road safety. This thesis explores a new TOR interface design, called the Context-Aware Adaptive (CAA) design, which uses both visual and auditory cues to improve drivers’ awareness of urgency and understanding of takeover reasons. Using a Research through Design (RtD) methodology and a Mixed Methods approach (quantitative and qualitative), four dynamic driving scenarios of varying lengths and takeover reasons were simulated in Virtual Reality (VR) to test two TOR designs: the CAA design and a Baseline design. Both designs were evaluated on usability and efficacy with 25 participants, using the Situation Awareness Global Assessment Technique (SAGAT), which is a freeze-probe technique, to assess people's perceived level of urgency at three critical time points (T1, T2, and T3). Results showed that the CAA design helped drivers better perceive the gradual change of urgency levels and understand takeover reasons compared to the Baseline design. This research contributes to Human-Machine Interaction (HMI) for SAVs, suggesting that adaptive, multimodal TOR alerts can improve the dynamic communication between SAVs and drivers, potentially enhancing safety and user experience in automated systems.
