Raah is an assistive device designed to help visually impaired users identify and
navigate toward objects in their environment. The system performs real-time object
detection using OpenCV and TensorFlow-based deep learning models, enabling accurate
recognition of everyday items.
Once an object is identified, Raah uses a two-stage haptic feedback algorithm to
guide the user safely toward the target. The first stage provides directional cues,
while the second stage offers distance-based feedback, ensuring intuitive and
reliable navigation without visual input.
Built to be lightweight, affordable, and user-friendly, Raah aims to improve
independence and situational awareness for visually impaired individuals.
