Blind Navigator, designed to help visually impaired users navigate websites more effectively. This description can be used for documentation, project proposals, or sharing with collaborators.
Project Description: Blind Navigator Overview Blind Navigator is a Chrome extension designed to assist visually impaired users in navigating websites with ease. The extension leverages text-to-speech (TTS) technology, keyboard navigation, and accessibility-focused features to make web content more accessible. It provides an intuitive and customizable interface, allowing users to interact with websites using audio feedback and keyboard controls.
