Additive manufacturing (AM), also known as 3D printing, is a promising tool to produce assistive technology. For instance, individuals with deafblindness (concurrent vision and hearing loss) could benefit from tactile AM-based products as touch may be their main gateway to access information. This study thus aimed to synthesize evidence on the…

Tactile graphics convert visual information into touchable patterns and braille, providing an essential solution for accessible graphics for individuals with visual impairments. Pioneering research advocates for the potential of audio-augmented tactile graphics, which convey complex information through auditory and tactile modalities rather than…

Introduction: Three-dimensional (3D) printing can be used to produce tactile teaching materials for individuals with visual impairments. Although 3D and 2.5D teaching materials are based on realistic content, no systematic conversion model for 2D materials exists. Here, we combined the previous findings and this study's results and technology to…

Purpose: This paper aims to evaluate the accessibility of digital information systems as a key usability attribute in information retrieval by users with visual impairment (VI), to inform development of accessible information systems. Design/methodology/approach: This study used a cross-sectional survey design based on the quantitative research…

The difficulties faced by teachers at a Special Public School in teaching Balinese script literacy to visually impaired children have resulted in low literacy skills in Balinese script among these students. In order to maximize Balinese script learning, appropriate learning media tailored to the characteristics of visually impaired children are…

In the late nineteenth century, Protestant missionaries introduced modern education for the blind people in Taiwan and Korea. They developed various tactile reading systems to enhance literacy and provided handicraft training for self-sufficiency. When these regions came under Japanese colonial rule in the first half of the twentieth century, the…

Professional development is essential for certified Teachers of students with Visual Impairments (TVIs) to create high-quality tactile graphics in school settings. The teachers need more opportunities to learn knowledge and skills from other teacher colleagues on a community basis. Few studies were conducted to investigate what community-based…

Families play an important role in ensuring their child with a disability has access to the educational materials they need to learn and succeed. This guide is designed for parents and caregivers of children who require accessible educational materials (AEM) for learning. It will provide you with information about what AEM are, how they can…

Courses at the postsecondary level continue to rely heavily on visual material that is accessible only to fully or partially sighted students. Tactile graphics work for many pedagogical purposes, but in some cases are insufficient; other information and concepts may be better conveyed through haptic exploration of 3D printed objects. However,…

The "Next Generation Science Standards" (NGSS) stress the need for all students to receive excellent science instruction--including those with disabilities--based upon disciplinary core ideas, crosscutting concepts, and science and engineering practices (NGSS Lead States 2013). Further, the NGSS emphasize reducing disparities in student…

Although very rare, the existing research on the biological education of blind people indicates that teaching content is not fully in line with the sensory perception of that content by the blind. The aim of this study is to analyse the morphological details which the blind can register in multisensory plant research and to harmonise the…

The AEM Navigator facilitates the process of decision-making around accessible formats of educational materials for individual students. It assists teams in making informed, accurate, and multi-step decisions related to determining a student's need for accessible formats, selecting the format(s) needed, acquiring materials, and determining the…
