On the Relation between Assistive Technology System Elements and Access to Assistive Products Based on 20 Country Surveys - Research Summary
Wei Zhang, Johan Borg, Irene Calvo, Chapal Khasnapis, Mikael Winberg, Arne H EideNov. 1, 2024Research SummariesClick here to read a summary of the WHO-led 2021 study on global access to assistive technology (AT). The study reveals significant disparities in AT access, with rates ranging from less than 3% to 90% across countries. While many nations have AT policies, only 30% provide comprehensive services, and just 10% have sufficient trained personnel. Further research is essential to evaluate specific initiatives and enhance equitable access worldwide.

Scaffolding Digital Literacy Through Digital Skills Training for Disabled People in the Global South
Laxmi Gunupudi, Maryam Bandukda, Giulia Barbareschi, Tigmanshu Bhatnagar, Aanchal Singh, Satish Mishra, Amit Prakash, Catherine HollowayOct. 27, 2024Academic Research PublicationsDigital inclusion is key to the UN’s Sustainable Development Goals. In LMICs, limited digital skills hinder employment, especially for disabled individuals. Our study in India and Kenya trained 138 participants using classroom instruction and WhatsApp-based peer learning. We found that inclusive scaffolding and community-based learning are essential, leading to a new digital scaffolding framework extending Vygotsky’s Theory to enhance digital skills for all.

Development of Priority Assistive Product Lists in Three African Countries
Emma M. Smith, Ikenna D. Ebuenyi, Ying Zhang, Laura LigthartOct. 23, 2024Academic Research PublicationsNational Assistive Product Lists (APLs) are vital for improving access to assistive products, which enhance the well-being of people with disabilities and functional limitations. This study compares how the World Health Organization’s 5Ps model (people, personnel, policy, provision, products) influenced the development of national APLs in Malawi, Liberia, and Sierra Leone, aiming to improve assistive product service delivery.

PRET Printer: Development and Evaluation of a Passive Refreshable Tactile Printer
Catherine Holloway, Tigmanshu BhatnagarAug. 28, 2024Academic Research PublicationsWhile audio-based interfaces make information accessible to people with visual impairments, some information, such as diagrams, graphs, and charts, can be better interpreted tactilely. We introduce a new Passive Refreshable Tactile (PRET) Printer concept. Using off-the-shelf components of a laser engraver and the nascent Tacilia technology, the prototype enables the creation of refreshable tactile graphics.

Mapping Assistive Technology Start-ups
Catherine Holloway, Tigmanshu Bhatnagar, Patel DilishaJuly 16, 2024GlobalAcademic Research PublicationsThis paper explored their experiences of providing and accessing AT, including procurement strategies, adoption of new technologies, and provision pathways. Overall, we found that there is still a substantial knowledge gap in assistive products, how to access products, and funding for needed products. These discussions also enlightened us that word-of-mouth and peer networks are the main avenues through which knowledge of assistive products is shared. Difficulties in keeping up with the expanding innovative landscape was raised as a key concern.
