Effects of AR-HUD forward collision warning designs on drivers' braking behavior and visual attention in highway driving: an eye-tracking study.
While augmented reality head-up displays (AR-HUDs) are known to enhance forward collision warning (FCW) safety, the optimal design for highway scenarios remains unclear. This study evaluated three AR-HUD FCW designs, including spatial referencing (SR), scaling animation (SA), and static symbol (SS), against a no-warnin...
