    Autonomous urban mobility is an essential aspect of the quality of life for visually impaired individuals, who often face physical and architectural barriers aggravated by the lack of accessibility in cities. Traditional tools, such as the white cane, although fundamental, have limitations in detecting aerial obstacles and in the semantic identification of the environment. Given this scenario, this work proposes the development of a wearable visual assistance system based on the Internet of Things (IoT) and Artificial Intelligence. The solution applies Computer Vision technology as a way to understand the environment. The Image capture and distance measurement are performed by an ESP32-CAM module, while heavy processing and inference occur on an external server. The main innovation lies in the feedback delivery: the server processes the image and sends the synthesized audio alert (Text-to-Speech) in real-time via the WebSocket protocol to an Android mobile application, which instantly reproduces the message through the user's headphones. To validate the proposal, tests were performed that could identify objects and report their distance with low latency. The results demonstrate that the integration between IoT, cloud processing, and mobile devices contributes significantly to increasing safety, contextual perception, and locomotion independence for the visually impaired.
