The document describes a cognitive navigation and object detection system for blind people. The objective is to design an electronic travel aid system that uses stereovision to inform blind users about nearby static and dynamic objects through acoustic signals. It also aims to provide navigation assistance. The proposed system uses stereo cameras and a processing unit to detect objects and free space, generate depth maps, and estimate object properties. It then sends acoustic signals to headphones to convey distance, direction, height, speed and other details about detected objects and the surrounding environment to help blind users navigate and be aware of their surroundings. An initial prototype and experimental trials are presented.
