An assistive product (AP) is defined as a product used exter-nally to the human body, whose primary purpose is to main-tain or improve an individual’s functioning and independence and thereby promote his or her well-being (WHO, 2016). Global population aging forecasts a rise in the need for solu-tions that support participation and independence, including APs. 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.

Shape changing materials create a unique opportunity to design reconfigurable tactile display actuators. In this paper, we present a method that transforms a single thin monolithic sheet of Nitinol into a passive reconfigurable tactile pixel array at Braille resolution. We have designed a 27x27 tactile pixel array in which each pixel can be selectively actuated with an external source of heat. The pixels rise 0.4mm vertically with a peak blocked force of 0.28kg and have an average blocked force of 0.23kg at room temperature. After cooling, the pixels can be mechanically reconfigured back to their flat state for repeatable actuation. We demonstrate this actuator’s interactive capabilities through a novel erasable tactile drawing interface.

Information and communication technology (ICT) tools can have a catalytic effect in advancing both educational access and learning outcomes for children with disabilities. Despite tremendous potential, a gap exists between technology advancements and their large-scale application in educating children with disabilities in low- and middle-income countries. This landscape review of ICTs for disability-inclusive education by the Inclusive Education Initiative seeks to understand the current status and trends in the practice of educational technology (EdTech) and the use of ICT in improving the educational participation and outcomes of children with disabilities. The review explores what factors enable or restrict this improvement within the wider EdTech ecosystem.
GDI Hub partnered with the World Bank to design and conduct the research, and author the ICT Landscape review: The use of ICT in improving the educational participation and outcomes of children with disabilities. This report is a global knowledge product from the Inclusive Education Initiative (IEI)—a multi-donor trust fund on disability-inclusive education managed by the World Bank, with support from the Norwegian Agency for Development Cooperation (Norad) and the United Kingdom’s Foreign, Commonwealth and Development Office (FCDO).
