The plastination technique produces non-toxic human tissues, ensuring their safe handling in educational settings. This investigation aimed to understand if visually impaired students profit from the use of plastinated anatomical specimens in learning the anatomy of the nervous system. For this purpose, their learning performance was compared to…

The scope of this paper is to examine the potential capabilities of embossed printers under the lens of Information Technology (IT). One of the main principles of IT is to manage and deliver information into accessible formats to all users with and without disabilities. The present study investigates the discriminability of lines and squares by…

Introduction: Recent trends in training teachers of students who are blind or have low vision (i.e., those who are visually impaired) have shifted away from traditional hand-over-hand guidance and toward a hand-under-hand approach. However, a search for peer-reviewed studies that address the effects of the use of hand-under-hand versus…

Introduction: There are major differences when children with blindness perform construction tasks using haptics, without relying on sight, compared to when children with typical vision perform them through sight. When using sight, in all of the processes, the overall image can be grasped simultaneously while executing the task. When using haptics,…

Introduction: The objective of the current study was to design and pilot-test a nonverbal intelligence test for children and adolescents with visual impairment (i.e., blindness and low vision) aged 10 to 16 years. Method: A three-dimensional haptic matrix test of nonverbal cognitive abilities (3-DHMT-CA), initially developed for adults with visual…

Deaf-sighted, deaf-blind, and hearing-sighted people have been interacting within a small community in the Bay Islands of Honduras for over a century (Ali 2023; Ali and Braithwaite 2020). In this article, we sketch the history of the community and the ways in which signers make use of their own and their interlocutor's bodies to co-construct…

This review examines research on math achievement in students who are blind or visually impaired (BVI), and seeks to show the opportunities that BVIs have access to in order to demonstrate their knowledge of mathematics as well as the unique challenges they face and the ways in which these barriers have (or have not) been addressed. Math…

Introduction: Many tactile graphics designed for individuals with visual impairments consider single factors. According to the results of our previous study, there may be interactions among scale, representation, and complexity factors. We conducted this integrative study with these three factors. Additionally, for the representation factor, we…

The development of accessible elements in museum exhibitions is an important pursuit that needs a well-defined process. Educators at the Smithsonian National Air and Space Museum, working with accessibility professionals and blind or low-vision user/experts, discovered the value of co-designing tactile models with the people who would eventually…

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: This work investigates if simple two-dimensional (2D) tactile shapes can facilitate encoding, retention, and retrieval of associated information in the form of one-word labels. It also questions the need for the resemblance of tactile graphics with respective visual referents. Methods: Four experiments were conducted using recall…

Ocean currents play an important role in regulating the Earth's climate by redistributing ocean heat around the planet. One important climate phenomenon that includes several large ocean currents is the Atlantic Meridional Overturning Circulation, which is the process of warm surface currents in the North Atlantic Ocean moving to the Arctic to…

Students with visual impairment have the same range of mental abilities as their sighted peers. However, these students experience academic failure, especially in courses in which visual themes are dominant, as they cannot use their sense of sight to process information sufficiently. One of the courses that students with visual impairment have the…

The aim of this dissertation is to bring to light factors that affect how people who are blind or visually impaired (BVI) access, consume, design and produce with different types of tactile media for themselves or for others who are also BVI. Toward the goal of creating equity within the media and information landscape and beyond, this…

Tactile, motor and cognitive capacities decline with age, but little is known about how this relates to braille reading outcomes. This study investigated correlates of braille reading speed among working-age and older adults. Texts were read in two modes (oral/silent) and two media (paper/electronic braille display) by 46 blind adults (age range…
