In our surrounding the Communication generally takes place through speech and text. The aim of this project is to provide an assistive technology to help the visually impaired person usage in disaster situations. The purpose of our paper is to develop a cap for blind which will guide them from their source to destination. The solution for smart Cap is to support visually Impaired person and it is cost effective wearable 'smart cap’. The Proposed system consists of web camera which is fitted into a cap, audio microphone, Raspberry pi, speaker for voice. The software’s use in this project is Image processing. open cv, numpy, python. A OCR software is used for converting the details of the detected object (in text format) to speech output. This project is to provide an assistive technology to help the blind people or visually impaired navigate their way out of any potentially disastrous situation. Smart Cap easily navigate the paths and detect obstacles. Smart Cap" give blind people confidence to walk confidently on busy road. The main advantage of this project to use in critical condition. The system and its usage in disaster situations is an innovative, cost-effective solution specifically addressing the needs of visually impaired persons.
