A navigation system for individuals suffering from blindness or visual impairment provides information useful to reach a destination. Although there are different approaches, traditional designs are evolving into distributed systems with low-cost, front-end devices. These devices act as a medium between the user and the environment, encoding the information gathered on the surroundings according to theories on human perceptual and cognitive processes. Ultimately, they are rooted in sensorimotor coupling. The present work searches for temporal constraints due to such human–machine interfaces, which in turn constitute a key design factor for networked solutions. To that end, three tests were conveyed to a group of 25 participants under different delay conditions between motor actions and triggered stimuli. The results show a trade-off between spatial information acquisition and delay degradation, and a learning curve even under impaired sensorimotor coupling.

The term “indoor navigation system” pertains to a technological or practical approach that facilitates the navigation and orientation of individuals within indoor settings, such as museums, airports, shopping malls, or buildings. Over several years, significant advancements have been made in indoor navigation. Numerous studies have been conducted on the issue. However, a fair evaluation and comparison of indoor navigation algorithms have not been discussed further. This paper presents a comprehensive review of collective algorithms developed for indoor navigation. The in-depth analysis of these articles concentrates on both advantages and disadvantages, as well as the different types of algorithms used in each article. A systematic literature review (SLR) methodology guided our article-finding, vetting, and grading processes. Finally, we narrowed the pool down to 75 articles using SLR. We organized them into several groups according to their topics. In these quick analyses, we pull out the most important concepts, article types, rating criteria, and the positives and negatives of each piece. Based on the findings of this review, we can conclude that an efficient solution for indoor navigation that uses the capabilities of embedded data and technological advances in immersive technologies can be achieved by training the shortest path algorithm with a deep learning algorithm to enhance the indoor navigation system.

“…Heat or trace maps for movement analysis have seen use in other works, e.g. [29]- [33], and can provide useful results. Using the numeric computing platform Matlab [34], the VR recordings, and the event analysis, participants' movement is traced on a VE in planar view, the traces colored blue for independent walking; yellow for guided walking due to a method issue; or red if due to a feedback issue.…”

Numerous electronic travel aids (ETAs) to increase the mobility of blind or low-vision (BLV) individuals have been proposed. However, the lack of established and well-motivated methods, and of recruiting enough BLV test participants, keeps a successful aid illusory. To combat this, a new aid-agnostic questionnaire focused on mobility, the Desire of Use Questionnaire for Mobility of BLV individuals (DoUQ-MoB) and a new portable, large-scale-exploration virtual reality (VR) system, the Parrot-VR, were employed to evaluate the ETA Audomni. Through VR and Audomni, 19 heterogenous BLV participants traversed large-scale urban environments. Their experiences were probed through the DoUQ-MoB, and their movement analyzed. Numerous results are presented, a highlight being that most participants, 76 %, responded that it was very or extremely likely that they would want to use Audomni along with their current aid. Further, Parrot-VR assists in recruiting a satisfying number of diverse BLV participants; and DoUQ-MoB allows to systematically probe their opinions of an aid, and how it relates to others aids, in a considerable quantity of mobility aid aspects. This work illuminates some shortcomings of Audomni, but also shows a majority of BLV participants actually wanting to use a proposed ETA -a result rarely seen so distinctly in the field, and which encourages the continuing efforts of the project. The results are supported by a novel test procedure, which might serve as future inspiration to the field.
