VisionAid

VisionAid is an open-source project made to help visually impaired people understand what is around them. The system uses a webcam and computer vision to detect objects and read text. After detecting objects or text, the system speaks the information so that the user can hear it. This helps users know about their surroundings even without using the internet.

The main goal of this project is to build a simple and useful AI assistant that works completely offline. Many existing assistive systems need internet connection to work because they process data in cloud servers. This can cause problems in places where internet is not available. VisionAid solves this problem by doing all the processing directly on the user’s computer.

The system takes live video from the webcam and analyzes each frame using computer vision techniques. It uses an object detection model to identify common objects such as bottles, chairs, laptops, and people. When the system detects an object, it announces the name of the object using voice output so that the user can understand what is present in front of them.

The system can also read text using Optical Character Recognition (OCR). If a user shows a sign board, label, or document to the camera, the system can read the text and speak it aloud. This helps visually impaired users read important information easily.

VisionAid is built completely using open-source technologies. It uses tools like OpenCV for computer vision, YOLOv8 for object detection, and Tesseract OCR for text recognition. These tools allow the system to work in real time on a normal computer.

The project is designed in a way that more features can be added in the future. For example, future versions could include obstacle detection, navigation assistance, and mobile phone support. VisionAid shows how artificial intelligence and open-source software can be used to build helpful technology for people with disabilities.

By combining object detection, text reading, and voice output in one system, VisionAid aims to create a simple and affordable solution that helps visually impaired people become more independent and aware of their surrounding
