Abstract - The most significant difficulty for individuals
tracking provides real-time location data, enabling responders to pinpoint the user's exact whereabouts. This feature ensures that help is quickly mobilized, offering an added layer of security and peace of mind for visually impaired people who could find themselves in critical situations. Together, these features—navigation assistance and the "Help Me" button form a comprehensive solution that enhances both the freedom and safety of people with vision impairments, enabling them to move about their environment more confidently and with security.
who are visually impaired involves to reach their destination. Although smart helping sticks have been produced, they need to be carried around and have restrictions. The goal of the smart system "Help Me" and navigation aid functions is to greatly improve the ability to move and safety of those with visual impairments. The navigation assistance feature utilizes a GPS-based system and speech-to-text technology to provide real-time audio guidance, making users able to reach their desired destinations efficiently and independently. The "Help Me" feature is designed for emergency situations, where pressing a dedicated button activates an alert system that sends pre-configured messages along with the user's GPS location to designated contacts, ensuring immediate assistance. Together, these features offer a robust and userfriendly solution, improving the overall quality of as well as security for blind people.
2. LITERATURE REVIEW Those who are blind or visually handicapped have significant problems while navigating their surroundings. New developments in technology have prompted the creation of a number of systems targeted at improving object detection and navigational skills.
Key Words: Navigation assistance, GPS-based system,
Priya created a smart glasses-based assistive technology for those who are blind. For navigation, it makes use of face and object recognition. With the use of this technology, the user can recognize objects and people in front of them. Only those who have already registered with the system database can be identified by this system [1].

1.INTRODUCTION For those who are visually impaired, getting about all over may be quite difficult, particularly if it comes to autonomous travel and maintaining personal safety. This project presents cutting-edge solutions with two main elements to address these issues: navigation assistance and an emergency "Help Me" feature. Navigation assistance is important for visually impaired individuals to travel with confidence and ease. The proposed system integrates GPS-based voice navigation with real-time speech recognition to provide seamless guidance. By converting spoken destination requests into actionable directions, the system offers precise, audio-based instructions to help users reach their intended locations. The GPS functionality continuously tracks the user's position, ensuring they receive accurate directions and distance information. This approach not only simplifies the navigation process but also enhances the user's autonomy, allowing them to navigate complex environments and unfamiliar areas with greater ease. In emergencies, immediate assistance is crucial. The "Help Me" feature is developed to offer swift support in critical situations. With a simple press of the emergency button, the system sends out an alert message to pre-configured contacts, including family members and emergency services. Simultaneously, GPS

In this work by Israh Akbar, the usage of GPS mobile applications for blind pedestrian navigation was investigated. Improving user confidence in GPS-based applications' accuracy. The study made it easier to analyze and comprehend how blind individuals utilize technology to navigate. The study further aided in highlighting the deficiency of information provided to visually impaired individuals when navigating new surroundings. The fact that every participant mostly relied on the distance measuring units of the applications while being directed by the GPSbased applications further demonstrated the significance of using the right words and units [2]. Sanika Dosi developed a blind-friendly Android app that leverages real-time object recognition through a smartphone camera. By utilizing neural networks, the app can identify objects and provide audio feedback to the user. By enhancing the user's capacity to identify and interact with items in their surroundings, this invention may improve situational awareness and navigation [3].
