Visually impaired people can't easily access information in their surroundings, like street signs or objects in a room. Most things around us aren't written in braille, and asking for help isn't always comfortable.
This project aims to create a device that uses a camera to detect text and objects, then shows the information in braille using movable pins. It helps visually impaired users understand what's around them without needing to ask others. "The goal of this project is to help visually impaired individuals access information from their surroundings without needing to rely on others. Many things around us-like street signs, labels, or objects-cannot be understood without sight, and they are rarely available in braille. This project aims to create a device that uses a camera to detect text and objects, and then presents that information in braille through a tactile pin display. The overall goal is to improve independence, confidence, and everyday accessibility for blind users.
Additional Info
To achieve this goal, the project will involve several technical steps. First, a camera will be used to capture real-time images of the environment. These images will then be processed using Optical Character Recognition (OCR) to extract any visible text. That text will be converted into braille using a software algorithm. A custom-designed mechanism will then raise pins to display the braille characters on a tactile surface. This display will use a 3x2 pin grid, controlled by 3 (+ 1) servo motors. Finally, the device should be portable, simple to operate, and cost-effective for real-world use."
