Abstract:The purpose of this study was to undertake a systematic literature review on how vision enhancements, implemented using head-mounted displays (HMDs), can improve mobility, orientation, and associated aspects of visual function in people with low vision. Methods: The databases Medline, Chinl, Scopus, and Web of Science were searched for potentially relevant studies. Publications from all years until November 2018 were identified based on predefined inclusion and exclusion criteria. The data were tabulated and s… Show more
“…As pointed out by Htike et al (2020) and Erickson- Davis and Korzybska (2021), the majority of research on visual prostheses (and more generally: low vision aids) has focused on the technical aspects rather than the usability of these devices. One promising development has been the Functional Low-Vision Observer Rated Assessment (FLORA), a tool to provide a subjective assessment to capture the functional visual ability and well-being of visual prosthesis patients (Geruschat et al, 2015).…”
Objective. How can we return a functional form of sight to people who are living with incurable blindness? Despite recent advances in the development of visual neuroprostheses, the quality of current prosthetic vision is still rudimentary and does not differ much across different device technologies. Approach. Rather than aiming to represent the visual scene as naturally as possible, a Smart Bionic Eye could provide visual augmentations through the means of artificial intelligence (AI)-based scene understanding, tailored to specific real-world tasks that are known to affect the quality of life of people who are blind, such as face recognition, outdoor navigation, and self-care. Main results. Complementary to existing research aiming to restore natural vision with these devices, we propose a patient-centered iterative approach to provide visual augmentations designed to support a range of patient-relevant real-world tasks. Significance. The ability of a visual prosthesis to support everyday tasks might make the difference between abandoned technology and a widely adopted next-generation neuroprosthetic device.

“…This study represents the third phase in our project that aims to develop an effective mobility aid for people with LV and to evaluate its effectiveness quantitively with mobility trials. The first phase of our project, a systematic literature review on how current visual augmentations in HMDs affect mobility in people with LV [32], highlighted the lack of user involvement in the design and development stages of the aids, and the lack of qualitative data in most of the existing literature. To better understand the requirements for visual mobility aids in people with LV, we undertook four focus groups with 20 participants with LV as the second phase of our project.…”

People with low vision experience reduced mobility that affects their physical and mental wellbeing. With augmented reality (AR) glasses, there are new opportunities to provide visual and auditory information that can improve mobility for this vulnerable group. Current research into AR-based mobility aids has focused mainly on the technical aspects, and less emphasis has been placed on understanding the usability and suitability of these aids in people with various levels of visual impairment. In this paper, we present the results of qualitative interviews with 18 participants using HoloLens v1 and eight prototype augmentations to understand how these enhancements are perceived by people with low vision and how these aids should be adjusted to suit their needs. Our results suggested that participants with moderate vision loss could potentially perceive the most benefit from glasses and underlined the importance of extensive customizability to accommodate the needs of a highly varied low vision population.

“…A high immersion ensures more natural user behavior and is essential to conclude realistic humans' reactions to VR stimuli. A few papers list available HMD technologies and what types of visual information processing have already been examined to improve mobility performances or support people with low vision [18,22,30]. Due to the first-person perspective (1PP) presented in HMD with a real-time calculation of rotations and translations of participant's body, a high relationship to realistic interaction within a computergeneralized three-dimensional world can be ensured and further recommended also for sportsrelated purposes.…”
In recent years, Virtual Reality (VR) has become a valuable tool in rehabilitation and sports training applications. New technologies offer opportunities to combine various systems and use them for sports-related scientific purposes. For instance, examining the visual perception of athletes within a standardized environment could be helpful to understand the differences between novices and experts in their visual behavior and could further reveal possible training applications for enhancing athletes’ visual attention. The current systematic literature review thematizes the importance of eye-tracking (ET) systems’ usage integrated into head-mounted displays (HMDs) in virtual environments for further inclusion in sports-related usage. An overview of possible implementations is given, and additional recommendations for using the combined technic regarding sports are made. Although only one study examined gaze behavior during sports activity within a standardized virtual environment, 38 relevant papers were identified using the ET systems integrated into the HMDs, which ideas can be transferred to the sports sector. The increased usability and fidelity in the virtual environment enabled through the combined technology were illustrated, and different approaches were listed in using and calculating gaze parameters. This literature review examines the possibility of integrating ET in VR, which can be further used to improve usability, interaction methods, image presentation, and visual perception analyses within future physical training scenarios. The compiled studies have shown that the existing methods are feasible due to the performance of the integrated ET systems but still need to be improved for practical use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
