Authors - Keerthi AJ, Kalyanasundaram V, Srinivasa Perumal R Abstract - Individuals who are visually impaired or have dual sensory impairments, such as both hearing and vision loss, face significant challenges in navigating public spaces. These challenges often limit their independence and pose risks of unintentional harm to themselves and others. While traditional mobility aids like canes or guide dogs provide some assistance, they lack the ability to deliver real-time, comprehensive awareness of the user's surroundings. To address these limitations, The Intelligent system-powered Smart Device designed to enhance mobility and safety for visually impaired individuals. This device leverages advanced object detection technology to enable users to navigate public spaces more effectively and confidently. The solution employs a SSD MobileNetV3 Convolutional Neural Network (CNN) model for real-time, efficient, and accurate object detection. Integrated with the Ov7670 for computer vision tasks and an Arduino microcontroller for hardware coordination, the system captures live video through a mounted camera to detect and classify obstacles. Users receive instant alerts via auditory or haptic feedback, promoting safer navigation. To ensure robust performance, Azure Custom Vision is used to evaluate and visualize the precision, recall, and average precision (AP) using the COCO dataset. By offering enhanced mobility and reducing risks, this innovative device fosters independence and inclusivity for visually impaired individuals in public environments.
