For the bio rnetric systern, the classification rnodels achieved high accuracy using SVM when tested on unseen data. The validation process confirrned the ability to detect a range of driver states, including eye closure, head distraction, and yawning, by processing extracted features and derived behavioral rnetrics such as blink rate. The outcornes of this thesis highlight the irnportance of designing AV interfaces that cornmunicate its situational awareness, while being capable of acquiring user behavioral in forrnation. The findings support future integration of such systerns into shared rnobility con texts, with potential extensions including user feedback rnodalities, real-time driver alerting mechanisrns, and multi-user calibration capabilities for broader deployment.
