The Picture Exchange Communication System (PECS) has been widely used to teach functional requesting and commenting skills to children with autism spectrum disorder. Some researchers also modified the PECS to explore its effect on children with other disabilities. The main purpose of this study was to add tangible symbols to PECS (PECS-TS) in…

Visual representations, such as graphics and shapes, are modes of presenting information that can pose a challenge for individuals with visual impairments. To address this issue, mobile technologies that provide tactile and auditory stimuli have been developed to ensure equal learning opportunities for individuals with visual impairments. The…

Introduction: Visual model comprehension and application are important for success in science, technology, engineering, and mathematics (STEM) courses. As educational materials shift to primarily digital content with dynamic interactive visuals, students with visual impairments are at risk for being disadvantaged, since few interactives are born…

Programming can be challenging to learn, and for visually impaired (VI) learners, there are numerous additional barriers to the learning process. Many modern programming environments are inaccessible to VI learners, being difficult or impossible to interface with using a screen reader. A review of the literature has identified a number of…

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…

One of the key abilities that every student should learn is mastering math skills. It is particularly difficult for blind students who have problems with access to information that is usually presented graphically for common pupils. One of such information in the case of mathematics is the presentation of graphs of functions and geometric shapes.…

This work discusses the construction and evaluation of a digital thermometer especially designed to be operated by people with visual disabilities. The accessibility thermometer can be used as an educational tool in practical activities in classes for sighted and visually impaired students, with the aim of helping those with special needs gain…

Introduction: As the number of people with visual impairments (that is, those who are blind or have low vision) is continuously increasing, rehabilitation and engineering researchers have identified the need to design sensory-substitution devices that would offer assistance and guidance to these people for performing navigational tasks. Auditory…

This paper addresses a central need among people who are blind, access to inquiry-based science learning materials, which are addressed by few other learning environments that use assistive technologies. In this study, we investigated ways in which learning environments based on sound mediation can support science learning by blind people. We used…
