Introduction: To improve access to assistive products (APs) globally, data must be available to inform evidence based decision-making, policy development and evaluation, and market-shaping interventions.

Methods: This systematic review was undertaken to identify studies presenting population-based estimates of need and coverage for five APs (hearing aids, limb prostheses, wheelchairs, glasses and personal digital assistants) grouped by four functional domains (hearing, mobility, vision and cognition).

Results: Data including 656 AP access indicators were extracted from 207 studies, most of which (n=199, 96%) were cross-sectional, either collecting primary (n=167) or using secondary (n=32) data. There was considerable heterogeneity in assessment approaches used and how AP indicators were reported; over half (n=110) used a combination of clinical and self-reported assessment data. Of 35 studies reporting AP use out of all people with functional difficulty in the corresponding functional domains, the proportions ranged from 4.5% to 47.0% for hearing aids, from 0.9% to 17.6% for mobility devices, and from 0.1% to 86.6% for near and distance glasses. Studies reporting AP need indicators demonstrated >60% unmet need for each of the five APs in most settings.

Conclusion: Variation in definitions of indicators of AP access have likely led to overestimates/underestimates of need and coverage, particularly, where the relationship between functioning difficulty and the need for an AP is complex. This review demonstrates high unmet need for APs globally, due in part to disparate data across this sector, and emphasises the need to standardise AP data collection and reporting strategies to provide a comparable evidence base to improve access to APs.

Artificial Intelligence (AI) in Education has been said to have the potential for building more personalised curricula, as well as democratising education worldwide and creating a Renaissance of new ways of teaching and learning. Millions of students are already starting to benefit from the use of these technologies, but millions more around the world are not. If this trend continues, the first delivery of AI in Education could be greater educational inequality, along with a global misallocation of educational resources motivated by the current technological determinism narrative. In this paper, we focus on speculating and posing questions around the future of AI in Education, with the aim of starting the pressing conversation that would set the right foundations for the new generation of education that is permeated by technology. This paper starts by synthesising how AI might change how we learn and teach, focusing specifically on the case of personalised learning companions, and then move to discuss some socio-technical features that will be crucial for avoiding the perils of these AI systems worldwide (and perhaps ensuring their success). This paper also discusses the potential of using AI together with free, participatory and democratic resources, such as Wikipedia, Open Educational Resources and open-source tools. We also emphasise the need for collectively designing human-centered, transparent, interactive and collaborative AI-based algorithms that empower and give complete agency to stakeholders, as well as support new emerging pedagogies. Finally, we ask what would it take for this educational revolution to provide egalitarian and empowering access to education, beyond any political, cultural, language, geographical and learning ability barriers.

Extracting useful information from the user history to clearly understand informational needs is a crucial feature of a proactive information retrieval system. Regarding understanding information and relevance, Wikipedia can provide the background knowledge that an intelligent system needs. This work explores how exploiting the context of a query using Wikipedia concepts can improve proactive information retrieval on noisy text. We formulate two models that use entity linking to associate Wikipedia topics with the relevance model. Our experiments around a podcast segment retrieval task demonstrate that there is a clear signal of relevance in Wikipedia concepts while a ranking model can improve precision by incorporating them. We also find Wikifying the background context of a query can help disambiguate the meaning of the query, further helping proactive information retrieval.

Purpose
To explore the personal and system factors that motivate and enhance outcomes for patients accessing a prosthetic service and using a lower-limb prosthesis within a low resource setting.

Materials and methods
This study employed a qualitative approach to explore the motivations and satisfaction of individuals with lower limb loss engaging with a prosthetic service in Mombasa, Kenya. In-depth interviews were conducted over Microsoft Teams with 10 lower limb prosthesis users and thematic analysis was applied.

Results
Five key themes emerged: acceptance, self-determination, hope, clinician relationship and perception. These findings demonstrate the importance of hopeful thinking and a supportive community in overcoming physical and stigmatising challenges. The findings further highlight the value of the service provider relationship beyond just prescribing an assistive device.

Conclusion
These results have relevance in developing patient-centred services, assistive devices and personnel training that are responsive, motivating, and cognisant of the service user. This is of particular interest as assistive technology services are newly developed in low resource settings.

The importance of assistive technology (AT) is gaining recognition, with the World Health Organisation (WHO) set to publish a Global Report in 2022. Yet little is understood about access for the poorest, or the potential of AT to enable this group to participate in the activities of citizenship; both formal and informal. The aim of this qualitative study was to explore AT as mediator of participation in citizenship for persons with disabilities who live in two informal settlements in Freetown, Sierra Leone (SL). The paper presents evidence from 16 participant and 5 stakeholder interviews; 5 focus groups and 4 events; combining this with the findings of a house-to-house AT survey; and two national studies—a country capacity assessment and an informal markets deep-dive. Despite citizenship activities being valued, a lack of AT was consistently reported and hindered participation. Stigma was also found to be a major barrier. AT access for the poorest must be addressed if citizenship participation for persons with disabilities is a genuine global intention and disability justice is to become a reality.

Elastomeric liners are commonly worn between the prosthetic socket and the limb. A number of improvements to the state of the art of liner technology are required to address outstanding problems. A liner that conforms to the residuum more accurately, may improve the skin health at the stump-socket interface. Previous work has shown that for effective thermal management of the socket environment, an active heat removal system is required, yet this is not available. Volume tracking of the stump could be used as a diagnostic tool for looking at the changes that occur across the day for all users, which depend on activity level, position, and the interaction forces of the prosthetic socket with the limb. We believe that it would be advantageous to embed these devices into a smart liner, which could be replaced and repaired more easily than the highly costly and labour-intensive custom-made socket. This paper presents the work to develop these capabilities in soft material technology, with: the development of a printable nanocomposite stretch sensor system; a low-cost digital method for casting bespoke prosthetic liners; a liner with an embedded stretch sensor for growth / volume tracking; a model liner with an embedded active cooling system.

Disability stigma in many low- and middle-income countries represents one of the most pervasive barriers preventing people with disabilities from accessing equal rights and opportunities, including the uptake of available assistive technology (AT). Previous studies have rarely examined how disability stigma may be shaped through factors endemic to social interactions, including how the use of assistive technology itself may precipitate or alleviate disability stigma. Through two strands of work, we address this gap. Via a series of focus groups with Kenyans without disabilities (Study 1) and secondary data analysis of consultations with Kenyans with disabilities and their allies (Study 2), we identify shared and divergent understandings of what shapes disability stigma and discrimination. Specifically, Kenyans with and without disabilities were cognizant of how religious/spiritual interpretations of disability, conceptions of impairments as “different” from the norm, and social stereotypes about (dis)ability shaped the experience of stigma and discrimination. Moreover, both groups highlighted assistive technology as an influential factor that served to identify or “mark” someone as having a disability. However, whereas participants without disabilities saw assistive technology purely as an enabler to overcome stigma, participants with disabilities also noted that, in some cases, use of assistive technologies would attract stigma from others.

Living in informality is challenging. It is even harder when you have a mobility impairment. Traditional assistive products such as wheelchairs are essential to enable people to travel. Wheelchairs are considered a Human Right. However, they are difficult to access. On the other hand, mobile phones are becoming ubiquitous and are increasingly seen as an assistive technology. Should therefore a mobile phone be considered a Human Right? To help understand the role of the mobile phone in contrast of a more traditional assistive technology – the wheelchair, we conducted contextual interviews with eight mobility impaired people who live in Kibera, a large informal settlement in Nairobi. Our findings show mobile phones act as an accessibility bridge when physical accessibility becomes too challenging. We explore our findings from two perspective – human infrastructure and interdependence, contributing an understanding of the role supported interactions play in enabling both the wheelchair and the mobile phone to be used. This further demonstrates the critical nature of designing for context and understanding the social fabric that characterizes informal settlements. It is this social fabric which enables the technology to be useable.

The supply of and market demand for assistive products (APs) are complex and influenced by diverse stakeholders. The methods used to collect AP population-level market data are similarly varied. In this paper, we review current population-level AP supply and demand estimation methods for five priority APs and provide recommendations for improving national and global AP market evaluation. Abstracts resulting from a systematic search were double-screened. Extracted data include WHO world region, publication year, age-groups, AP domain(s), study method, and individual assessment approach.497 records were identified. Vision-related APs comprised 65% (n = 321 studies) of the body of literature; hearing (n = 59), mobility (n = 24), cognitive (n = 2), and studies measuring multiple domains (n = 92) were proportionately underrepresented. To assess individual AP need, 4 unique approaches were identified among 392 abstracts; 45% (n = 177) used self-report and 84% (n = 334) used clinical evaluation. Study methods were categorized among 431 abstracts; Cross-sectional studies (n = 312, 72%) and secondary analyses of cross-sectional data (n = 61, 14%) were most common. Case studies illustrating all methods are provided. Employing approaches and methods in the contexts where they are most well-suited to generate standardized AP indicators will be critical to further develop comparable population-level research informing supply and demand, ultimately expanding sustainable access to APs.

Humanitarian coordination systems increasingly recognize and aim to respond to the needs of people with disabilities within populations affected by crises, spurred on by the UN Convention on the Rights of Persons with Disabilities (CRPD) which was adopted in 2006. Many agencies state their aim to meet the requirements of the CRPD using a “twin track” approach: ensuring the inclusion of people with disabilities in mainstream provision, alongside targeted support for their needs, which may include the need for Assistive Technology (AT). However, there is very little evidence of AT provision in humanitarian settings, which is a specific and urgent need for many people including the elderly and people with disabilities, and an implicit requirement of Article 11 of the CRPD and World Health Assembly resolution on improving access to assistive technology. There is also little evidence of effective mechanisms for AT provision in humanitarian settings. This is despite high and growing levels of unmet AT need in crises, and despite the legally binding requirement in the CRPD to provide AT for those who need it. AT provision faces unique challenges in humanitarian settings. This paper discusses the evidence available in the literature for the scale and quality of AT provision interventions in crises, and what is known about the challenges and facilitators of provision. We conducted a search of the academic literature and retained literature that reported on any form of AT provision following crisis, where international humanitarian response was in place, published in English between January 2010 and June 2020. We found very few examples in that academic literature of systematic and coordinated AT provision at the acute stage of crisis, and even less in the preparedness and post-acute stages. However, it is difficult to assess whether this is the result of insufficient academic attention or reflects a lack of provision. The small body of academic literature that describes AT provision in humanitarian settings paints a picture of small-scale provision, specialized to single types of impairments, and delivered by predominantly by NGOs. We also conducted a search of the gray literature, using the same inclusion criteria, in two countries: Afghanistan and South Sudan (case studies forthcoming). This gray literature provided supplementary evidence of the types of AT providers and AT provision available in those protracted crises. There are very few examples of how AT services can be scaled up (from a very low baseline) and maintained sustainably within a strengthened health system. The literature also describes more examples of provision of assistive products for mobility over assistive products for other impairments. If the paucity of literature on AT provision in humanitarian settings is a reflection of the scale of provision, this implies a deficiency in humanitarian response when it comes to providing people with AT needs with the essential products and services to which they have a right, and which will enable their access to basic, life-saving assistance. We conclude by providing recommendations for urgent actions that the AT and humanitarian community must take to fill this critical gap in the provision of essential products and services for a potentially marginalized and excluded group.

Globally, mobile technology plays a significant role connecting and supporting people with disabilities. However, there has been limited research focused on understanding the impact of mobile technology in the lives of persons with disabilities in low or middle- income countries. This paper presents the findings of a participatory photovoice study looking at the role that mobile phones play in the daily lives of 16 persons with disabilities in Kenya and Bangladesh. Participants used a combination of pictures and voice recordings to capture their own stories and illustrate the impact that mobile phone use has on their lives. Through thematic analysis, we categorized the benefits of mobile phones captured by participants as 1) Improved social connection; 2) Increased independence and 3) Access to opportunities. While mobile phones are ubiquitously used for communication, for persons with disabilities they become essential assistive technologies that bridge barriers to opportunities which are not accessible otherwise. Our paper adds evidence to the need for mobile phones for persons with disabilities to enable communication and connectivity in support of development.

From multiple studies conducted through the FCDO AT2030 Programme, as well as key literature, we examine whether Assistive Technology (AT) provision models could look towards more sustainable approaches, and by doing this benefit not only the environment, but also address the problems that the current provision systems have. We show the intrinsic links between disability inclusion and the climate crisis, and the particular vulnerability people with disabilities face in its wake. In particular, we discuss how localised circular models of production could be beneficial, facilitating context driven solutions and much needed service elements such as repair and maintenance. Key discussion areas include systems approaches, digital fabrication, repair and reuse, and material recovery. Finally, we look at what needs be done in order to enable these approaches to be implemented. In conclusion, we find that there are distinct parallels between what AT provision models require to improve equitable reliable access, and strategies that could reduce environmental impact and bring economic benefit to local communities. This could allow future AT ecosystems to be key demonstrators of circular models, however further exploration of these ideas is required to make sense of the correct next steps. What is key in all respects, moving forward, is aligning AT provision with sustainability interventions.

It is essential to understand the strategies and processes which are deployed currently across the Assistive Technology (AT) space toward measuring innovation. The main aim of this paper is to identify functional innovation strategies and processes which are being or can be deployed in the AT space to increase access to AT globally. We conducted a scoping review of innovation strategies and processes in peer-reviewed literature databases and complemented this by identifying case studies demonstrating innovation strategies. The review includes WHO world region, publication year, AT type and a sector analysis against the Systems-Market for Assistive and Related Technologies Framework. We analyzed the case studies and interviews using thematic analysis. We included 91 papers out of 3,127 after review along with 72 case studies. Our results showed that product innovations were more prevalent than provision or supply innovations across papers and case studies. Case studies yielded two themes: open innovation (OI); radical and disruptive innovation. Financial instruments which encourage OI are needed and we recommend pursuing OI for AT innovation. Embedding AT within larger societal missions will be key to success governments and investors need to understand what AT is and their translational socioeconomic value.
