SLAM for Visually Impaired People: A Survey
In recent decades, several assistive technologies for visually impaired and
blind (VIB) people have been developed to improve their ability to navigate
independently and safely. At the same time, simultaneous localization and
mapping (SLAM) techniques have become sufficiently robust and efficient to be
adopted in the development of assistive technologies. In this paper, we first
report the results of an anonymous survey conducted with VIB people to
understand their experience and needs; we focus on digital assistive
technologies that help them with indoor and outdoor navigation. Then, we
present a literature review of assistive technologies based on SLAM. We discuss
proposed approaches and indicate their pros and cons. We conclude by presenting
future opportunities and challenges in this domain.Comment: 26 pages, 5 tables, 3 figure
