Although in-car touchscreens expand interaction possibilities, they risk compromising driver safety and vigilance. We propose a data- and expert-informed framework for designing adaptive touchscreens that respond to a driver’s usage profile and cognitive state, maximizing usability while mitigating safety risks. First…

Touchscreens in Motion: Quantifying the Impact of Cognitive Load on Distracted Drivers

This study investigates the interplay between a driver's cognitive load, touchscreen interactions, and driving performance. Using an N-back task to induce four levels of cognitive load, we measured physiological responses (pupil diameter, electrodermal activity), subjective workload (NASA-TLX), touchscreen performance…

From Dashboards to Dialogue: Evaluating a Conversational AI Coach for Performance Driving Skill Development

Learning in domains involving complex motor skills, such as performance driving, often requires feedback that is timely, personalized, and actionable. Yet many drivers rely on video and telemetry data to review their performance without guidance. We explore how conversational AI can support post-drive reflection by in…
