RASPBERRY PI BASED SMART WALKING STICK FOR VISUALLY IMPAIRED PERSON Ravikumar S1, Krishnakumar M2, Karthikeyan S3, Balamuguran N4 1Assistant professor(Sel.G), Department of IT, SRM Valliammai Engineering College, Tamilnadu, India 2,3,4UG Students, Department of IT, SRM Valliammai Engineering College, Tamilnadu, India ---------------------------------------------------------------------***---------------------------------------------------------------Abstract - To provide a smart electronic help for blind individuals, a smart system concept has been designed. People who are blind or visually challenged have difficulty finding their way around. The Raspberry Pi-based system is designed to give artificial vision and object identification, as well as real-time support through GPS. In this project, we'll use the Raspberry Pi to create a smart system for blind people that includes a camera module, a switch, and a GPS module. If someone is in distress, the Pi Camera recognizes the location using GPS and sends a message to that person's Whatsapp. The system is made up of a GPS module that receives feedback via audio, and the voice output is controlled by TTS (text to speech). The suggested system identifies an object in their environment and gives feedback in the form of speech, warning messages sent by earphone, and GPS navigation to a specific area. The overall goal of the system is to deliver a low-cost, high-efficiency navigation and text-to-voice aid for the blind that provides a sense of artificial vision by supplying information about the environment's static and dynamic objects. Key Words: Artifical vision and object identifiaction, TTS(text to speech), GPS, Low-cost, high-efficiency navigation and text-to-voice. 1. INTRODUCTION Individuals with visual impairments are those whose good eyes make it impossible to understand even the smallest detail. Many people with 6/60 or the optical range have a longitudinal range of less than or equal to 20 degrees, or have both eyes wide open. These people are known to be deafeningly deafening visually handicapped persons live in a world where they are completely reliant on others. Individuals with sensory disabilities find it impossible to discern even the tiniest information from that of healthy people. Those with a 6/60 or optical range have a lateral scope of less than or equal to 20 degrees, orhave both eyes wide open. They are referred as as blind. According to the World Health Organization's global data on visual impairment, there are an estimated 285 million visually impaired persons of all ages, with 39 million of them blind. Blindness affects 80% of adults over the age of 50. Uncorrected refractive errors (43 percent) and cataract (33 percent) are the leading causes of visual impairment; cataract is the leading cause of blindness (51 percent ). Because humans receive 83 percent of their information from their surroundings through sight, vision is the most crucial element of their physiology. People with those illnesses face a lot of agony in order to live a normal life. They are mentally secluded and allow themselves to be neglected. This dysfunction with them has a significant impact on their ability to make a living. It manifests as a mental illness that causes patients to lose hope in themselves. As a result, we devised a system for those suffering from those conditions. In recent years, a number of inventors have created devices to assist visually impaired persons. Traditional and oldest accessibility devices for visually handicapped people have their own set of disadvantages. A unique supply or navigator is frequently included with some innovations, allowing the user to carry it in their pocket when travelling al fresco. The consumer is likely to be confused by the profuse patterns. Several attempts to construct blind guard or obstacle-measuring systems utilizing a small number of applications of elements have been made. As a result, it is recommended to design and create a walking stick with all of these functions, such as real-time object identification, voice direction, navigation, and so on, that is affordable to all persons who require assistance.
