Feghali JM, Feng C, Majumdar A, Ochieng WY. Comprehensive Review: High-Performance Positioning Systems for Navigation and Wayfinding for Visually Impaired People. SENSORS (BASEL, SWITZERLAND) 2024; 24:7020. [PMID: 39517914 PMCID: PMC11548674 DOI: 10.3390/s24217020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 08/18/2024] [Accepted: 08/20/2024] [Indexed: 11/16/2024]
Abstract
The global increase in the population of Visually Impaired People (VIPs) underscores the rapidly growing demand for a robust navigation system to provide safe navigation in diverse environments. State-of-the-art VIP navigation systems cannot achieve the required performance (accuracy, integrity, availability, and integrity) because of insufficient positioning capabilities and unreliable investigations of transition areas and complex environments (indoor, outdoor, and urban). The primary reason for these challenges lies in the segregation of Visual Impairment (VI) research within medical and engineering disciplines, impeding technology developers' access to comprehensive user requirements. To bridge this gap, this paper conducts a comprehensive review covering global classifications of VI, international and regional standards for VIP navigation, fundamental VIP requirements, experimentation on VIP behavior, an evaluation of state-of-the-art positioning systems for VIP navigation and wayfinding, and ways to overcome difficulties during exceptional times such as COVID-19. This review identifies current research gaps, offering insights into areas requiring advancements. Future work and recommendations are presented to enhance VIP mobility, enable daily activities, and promote societal integration. This paper addresses the urgent need for high-performance navigation systems for the growing population of VIPs, highlighting the limitations of current technologies in complex environments. Through a comprehensive review of VI classifications, VIPs' navigation standards, user requirements, and positioning systems, this paper identifies research gaps and offers recommendations to improve VIP mobility and societal integration.

[PMID: 39374412 DOI: 10.1080/10400435.2024.2411578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/25/2024] [Indexed: 10/09/2024] Open
Abstract
The entitlement to access assistive technology (AT) is fundamental for all individuals. However, challenges encountered during societal crises can significantly impact opportunities for participation and engagement among AT users. Understanding the implications of crises and disasters on AT provision along with their repercussions for end users is crucial. This research endeavors to investigate the experiences of managers overseeing AT provision during crises, using the first wave of the COVID-19 pandemic as a case study. An open-ended questionnaire was distributed to health care managers (n = 18) within AT organizations in Sweden. The responses were analyzed using qualitative content analysis, and four categories derived: Embracing change and navigating new realities, Optimizing strategies due to decreased and limiting prescriptions, Unlocking access and addressing challenges in AT provision, The impact on the staff and their well-being vs effectiveness in the AT organization. The findings indicate that AT organizations have demonstrated remarkable resilience and adaptability in the face of reduced consultations and growing care burden. Despite these challenges, managers have gained valuable insights into developing AT provision more efficiently and sustainably, particularly in digitization. The lessons learned will be critical in ensuring AT provision remains responsive to the needs of patients and society in the future.

Abstract
People with blindness and low vision (pBLV) encounter substantial challenges when it comes to comprehensive scene recognition and precise object identification in unfamiliar environments. Additionally, due to the vision loss, pBLV have difficulty in accessing and identifying potential tripping hazards independently. Previous assistive technologies for the visually impaired often struggle in real-world scenarios due to the need for constant training and lack of robustness, which limits their effectiveness, especially in dynamic and unfamiliar environments, where accurate and efficient perception is crucial. Therefore, we frame our research question in this paper as: How can we assist pBLV in recognizing scenes, identifying objects, and detecting potential tripping hazards in unfamiliar environments, where existing assistive technologies often falter due to their lack of robustness? We hypothesize that by leveraging large pretrained foundation models and prompt engineering, we can create a system that effectively addresses the challenges faced by pBLV in unfamiliar environments. Motivated by the prevalence of large pretrained foundation models, particularly in assistive robotics applications, due to their accurate perception and robust contextual understanding in real-world scenarios induced by extensive pretraining, we present a pioneering approach that leverages foundation models to enhance visual perception for pBLV, offering detailed and comprehensive descriptions of the surrounding environment and providing warnings about potential risks. Specifically, our method begins by leveraging a large-image tagging model (i.e., Recognize Anything Model (RAM)) to identify all common objects present in the captured images. The recognition results and user query are then integrated into a prompt, tailored specifically for pBLV, using prompt engineering. By combining the prompt and input image, a vision-language foundation model (i.e., InstructBLIP) generates detailed and comprehensive descriptions of the environment and identifies potential risks in the environment by analyzing environmental objects and scenic landmarks, relevant to the prompt. We evaluate our approach through experiments conducted on both indoor and outdoor datasets. Our results demonstrate that our method can recognize objects accurately and provide insightful descriptions and analysis of the environment for pBLV.

Abstract
We present a comprehensive review of the various challenges that individuals with visual impairment (VI) face during the COVID-19 pandemic. A structured review was done using online databases PubMed, EMBASE, and grey literature databases between 19 April 2021 and 4 August 2021, using search terms ‘COVID-19’, ‘SARS-CoV-2’, ‘Coronavirus’, or ‘pandemic’ combined with ‘visually impaired’, ‘visual impairment’, or ‘Blind’. Studies included were written in English, published after the World Health Organization (WHO) declaration of the COVID-19 Pandemic (11 March 2020), and focused on the VI population during the pandemic. The initial search yielded 702 publications, of which 20 met our inclusion criteria and were included in analysis. Emotional distress from deteriorating mental health and social isolation were considerably higher in the VI population. For a community that relies on spatial awareness and touch, regulations related to social distancing and avoiding contact were considerable barriers. Further challenges were noted in accessing healthcare, care, receiving timely health information and changes in regulations, adequately sanitizing, using technology, and completing activities of daily living. In the unprecedented times of the COVID-19 pandemic, the VI community has faced unique challenges. A more holistic and inclusive approach needs to be adopted to ensure that more vulnerable populations are adequately cared for.

Abstract
The COVID-19 pandemic caused unexpected and unavoidable changes in daily life worldwide. Governments and communities found ways to mitigate the impact of these changes, but many solutions were inaccessible to people with visual impairments. This work aimed to investigate how blind individuals subjectively experienced the restrictions and isolation caused by the COVID-19 pandemic. To this end, a group of twenty-seven blind and seventeen sighted people took part in a survey addressing how COVID-19 impacted life practically and psychologically, how it affected their daily habits, and how it changed their experiences of themselves and others. Results demonstrated that both sighted and blind individuals had a hard time adapting to the new situation. However, while sighted people struggled more with personal and social aspects, the frustration of the blind population derived mostly from more practical and logistical issues. Likely as consequences, results showed that blind people engaged more in their inner life and experienced fear and anger as main emotions. This study suggests that changes in life associated with COVID-19 have been subjectively experienced differently based on the presence or not of blindness, and that tailored future interventions should be considered to take care of the different needs of blind individuals.

Abstract
ABSTRACT The COVID-19 pandemic has propelled an unprecedented global implementation of telemedicine and telerehabilitation as well as its integration into the healthcare system. Here, we describe the clinical implementation of the A3E framework for the deployment of telerehabilitation in the inpatient and outpatient rehabilitation continuum by addressing accessibility, adaptability, accountability, and engagement during the COVID-19 pandemic. By using an organized, coordinated, and stratified approach, we increased our telerehabilitation practice from 0 to more than 39,000 visits since the pandemic began. Learning from both the successes and challenges can help address the need to increase access to rehabilitation services even beyond the COVID-19 pandemic.

Assistive Technology during the COVID-19 Global Pandemic: The Roles of Government and Civil Society in Fulfilling the Social Contract. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182212031. [PMID: 34831783 PMCID: PMC8625172 DOI: 10.3390/ijerph182212031] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 11/10/2021] [Accepted: 11/10/2021] [Indexed: 11/16/2022]
Abstract
The COVID-19 pandemic imposed significant challenges to users of assistive technology (AT). Three key issues emerged from a series of structured qualitative interviews with 35 AT users in six low- and middle-income countries. These were (1) access to information about COVID-19 and available supports and policies, (2) insufficiency of the government response to meet the needs of AT users, and (3) the response of civil society which partially offset the gap in government response. AT users noted the need for better communication, improved planning for the delivery and maintenance of AT during times of crisis, and higher-quality standards to ensure the availability of appropriate technology.

Abstract
The SARS COVID-19 pandemic emerged in 2019 and has impacted people everywhere. Disparities in impact and outcomes are becoming apparent for individuals and communities which go beyond the trajectory of the disease itself, influenced by the strength and weaknesses of systems of universal health care, and the actions of civil society and government. This article is one of a series exploring COVID-19-related experiences of assistive technology (AT) users across the globe and implications for AT systems strengthening. AT such as mobility products, braille devices, and information communication technologies are key enablers of functioning, necessary to the achievement of the UN Sustainable Development Goals and enshrined in the Convention on the Rights of Persons with Disabilities. Reporting on a survey of 73 AT users across six global regions, we demonstrate that minority groups already living with health inequities are unduly impacted. An AT ecosystem analysis was conducted using the WHO GATE 5P framework, that is, people, products, personnel, provision and policy. AT users and families call for inclusive pandemic responses which encompass their needs across the lifespan, from very young to very old. We offer specific recommendations for future action to strengthen access to AT across public policy and civil society in pandemic preparedness and response.
