Visual Impairment Navigation: Real-Time Contour Mapping with 3D Spatial Audio Feedback

To help the visually impaired navigate through their environment in real time, this research study proposes a novel navigation system. This navigation system works on various navigation algorithms for contour mapping, computer vision techniques for visual processing and deep learning models implemented using TensorFlow for obstacle recognition, OpenCV for real time visual input processing and Open AL for spatial audio mapping. All these technologies combine to create the “follow the beep” feature in integration with Unity 3D. While designing this navigation system factors such as user experience and navigation efficiency have been considered and therefore conventional methods have been implemented to do so.
