Driving Towards the Future: Exploring Human-Centered Design and Experiment of Glazing Projection Display Systems for Autonomous Vehicles

The automotive glazing projection display pertains to projecting information onto unique glazing materials in a car through projection equipment, a new direction of Human-Computer Interaction (HCI) in the intelligent cockpit. The core issue in glazing projection is determining what information should be projected onto the car's glazing and the area to which it should be projected. To address this issue, we conducted a focus group comprising 12 people. We distributed 1082 questionnaires to investigate future autonomous driving contexts, user information demands based on glazing projection, and regional preferences for displaying such information. We selected five contexts and nine high-rated features to design a driver-specific display interface. We conducted eye-movement experiments to investigate the effect of the projection interface on the driver's gaze behaviors under different display areas and subsequently modified the display areas. This study confirms the feasibility of the glazing projection display and provides theoretical support for HCI development in the intelligent cockpit.
