Road signs are recognized and their importance categorized. A driver's eyes are continuously scanned to determine whether the driver's eyes' ever focus on, or are directed to a detected and recognized road sign. Multiple different visual and/or audible warnings or alarms are generated based on the nature of a road sign, its proximity to the moving vehicle, and the driver's determined awareness of the road sign."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active warning system using the detection of driver awareness of traffic signs","description":"Traffic sign warnings are provided to a driver by optically scanning an area in front of the moving vehicle to obtain an image of said area in front of the moving vehicle.
