“…Unlike SSDs and invasive technologies, these general aids can potentially be used by people with or without vision. Despite the large number of conceptual papers on this topic, [216][217][218][219][220][221][222][223][224][225] we will focus our discussion on the few examples of SSDs that have been empirically tested in the context of navigation. For more comprehensive reviews of technological navigation aids and SSDs, see Refs 4,5,and 226. SSDs translate visual information into tactile information, auditory information, or both in a noninvasive manner.…”

Spatial navigation in the absence of vision has been investigated from a variety of perspectives and disciplines. These different approaches have progressed our understanding of spatial knowledge acquisition by blind individuals, including their abilities, strategies, and corresponding mental representations. In this review, we propose a framework for investigating differences in spatial knowledge acquisition by blind and sighted people consisting of three longitudinal models (i.e., convergent, cumulative, and persistent). Recent advances in neuroscience and technological devices have provided novel insights into the different neural mechanisms underlying spatial navigation by blind and sighted people and the potential for functional reorganization. Despite these advances, there is still a lack of consensus regarding the extent to which locomotion and wayfinding depend on amodal spatial representations. This challenge largely stems from methodological limitations such as heterogeneity in the blind population and terminological ambiguity related to the concept of cognitive maps. Coupled with an over‐reliance on potential technological solutions, the field has diffused into theoretical and applied branches that do not always communicate. Here, we review research on navigation by congenitally blind individuals with an emphasis on behavioral and neuroscientific evidence, as well as the potential of technological assistance. Throughout the article, we emphasize the need to disentangle strategy choice and performance when discussing the navigation abilities of the blind population.

“…The augmented white cane-based system is an indoor navigation system specifically designed to help the visual impaired move freely in indoor environments [ 74 ]. The prime purpose of the white cane navigation system is to provide real-time navigation information, which helps the users to make decisions appropriately, for example on the route to be followed in an indoor space.…”

The visually impaired suffer greatly while moving from one place to another. They face challenges in going outdoors and in protecting themselves from moving and stationary objects, and they also lack confidence due to restricted mobility. Due to the recent rapid rise in the number of visually impaired persons, the development of assistive devices has emerged as a significant research field. This review study introduces several techniques to help the visually impaired with their mobility and presents the state-of-the-art of recent assistive technologies that facilitate their everyday life. It also analyses comprehensive multiple mobility assistive technologies for indoor and outdoor environments and describes the different location and feedback methods for the visually impaired using assistive tools based on recent technologies. The navigation tools used for the visually impaired are discussed in detail in subsequent sections. Finally, a detailed analysis of various methods is also carried out, with future recommendations.

“…Velazquez, et al [5] designed a prototype of the Intelligent Glasses, a novel non-invasive ETA to assist the visually impaired to navigate easily, safely and quickly among obstacles in indoor/outdoor 3D environments. Santosh S S, et al [6] proposed "BLI-NAV", blind navigation system exclusively designed for blind people which allows the blind people to travel through familiar and unfamiliar environment. Ran L, et al [7], proposed "Drishti: an integrated indoor/outdoor blind navigation system and service", which provides dynamic routing and rerouting ability through vocal prompts.…”
