NavigateU: A Smart Navigation System For Disabled People Based on ML

This survey paper presents a comprehensive review of existing navigation and accessibility technologies designed for physically disabled, visually impaired, and elderly individuals. The study analyzed various approaches, including sensor-based systems, wearable devices, web-based navigation platforms, artificial intelligence-driven models, and augmented reality-based solutions. The findings indicate that significant progress has been made in improving independent mobility and navigation safety through assistive technologies. Systems incorporating multi-sensory feedback, real-time tracking, and intelligent route planning have shown promising results in enhancing user experience and accessibility. However, most existing solutions focus on specific aspects of navigation, such as indoor guidance, obstacle detection, or route optimization, without providing a fully integrated solution. The survey also identifies several critical limitations, including high implementation costs, lack of scalability, limited real-time environmental awareness, and insufficient accessibility-focused features in mainstream navigation systems. Additionally, many systems lack user personalization and fail to address the diverse needs of individuals with different types of disabilities. Based on the analysis, it is evident that there is a strong need for developing unified, cost-effective, and user-friendly navigation solutions that integrate accessibility filtering, real-time navigation support, and intelligent recommendation mechanisms. Future research should focus on combining modern web technologies, artificial intelligence, and crowd-sourced data to create scalable and adaptive systems. In conclusion, accessible navigation remains an evolving research area with significant potential to improve quality of life. By addressing existing research gaps and focusing on inclusive design principles, future systems can provide more efficient, reliable, and universally accessible navigation solutions.
