A Review of Vision-Based Assistive Systems for Visually Impaired People: Technologies, Applications, and Future Directions
It addresses the problem of enhancing mobility and independence for visually impaired individuals, but it is a review paper, so it is incremental in summarizing existing work.
This paper reviews recent advances in vision-based assistive systems for visually impaired people, focusing on technologies for obstacle detection, navigation, and user interaction, and discusses emerging trends and future directions.
Visually impaired individuals rely heavily on accurate and timely information about obstacles and their surrounding environments to achieve independent living. In recent years, significant progress has been made in the development of assistive technologies, particularly vision-based systems, that enhance mobility and facilitate interaction with the external world in both indoor and outdoor settings. This paper presents a comprehensive review of recent advances in assistive systems designed for the visually impaired, with a focus on state-of-the-art technologies in obstacle detection, navigation, and user interaction. In addition, emerging trends and future directions in visual guidance systems are discussed.
