Navigate U: A Smart Navigation System for Disabled People Based on ML

Abstract

Accessibility remains a major challenge for individuals with disabilities while navigating public spaces, mainly due to the lack of reliable and up-to-date information about accessible infrastructure. In this work, we present Navigate, a web-based accessible location discovery system developed using React.js, Firebase Firestore, Google Maps Platform, and Geolocation APIs. The system helps users identify nearby places that provide essential accessibility features such as ramps, lifts, wheelchair access, and accessible toilets. The application displays these locations on an interactive map and allows users to filter them based on their specific needs. Users can either use their current location or manually enter a place name, which helps address inaccuracies sometimes observed in network-based location detection. In addition, a voice-based filtering feature is included to make interaction easier for users with limited mobility.

All location data is stored in Firebase Firestore, enabling Realtime updates and allowing users to contribute new accessibility information. A lightweight recommendation approach is also implemented to suggest the most suitable location by considering both distance and available accessibility features.

The system was tested in real-world scenarios and was able to effectively assist users in identifying accessible places. Overall, the results indicate that web-based technologies can be used to build practical and user-friendly solutions for inclusive navigation.
