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…

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…

This paper introduces the tactile method and aims to explore the effectiveness of using tactile methods with students who are blind and visually impaired. Although there was limited research about using this strategy, all of the research agrees that using tactile is one of the best ways for students who are blind and visually impaired to be…

As a symbol of the power and majesty of science, the periodic table has inspired many scientists-to-be to investigate the deep secrets of nature through the study of chemistry. In the spirit of inclusion, blind students too deserve and need to have their curiosity about the inner workings of nature stimulated through greater exposure to this…

Diagram describing texts are integral part of science and engineering subjects including geometry, physics, engineering drawing, etc. In order to understand such text, one, at first, tries to draw or perceive the underlying diagram. For perception of the blind students such diagrams need to be drawn in some non-visual accessible form like tactile…

This study analyzed the quality of brailled instructional materials transcribed by 40 public school personnel. The authors calculated the correlation of the certification status of the personnel and the average amount of time spent transcribing per week with the total number of transcription errors. The findings suggest that students who read…

The report describes the development and evaluation of an instructional program in tangible graph interpretation for braille readers. Because graphs frequently appear in textbooks and in other printed sources, lack of appropriate translation for blind persons can be a significant educational obstacle. Based on anlyses of typical graph reading…

This study compared the length of text in English Braille American Edition, the Nemeth code, and the computer braille code with the Unified English Braille Code (UEBC)--also known as Unified English Braille (UEB). The findings indicate that differences in the length of text are dependent on the type of material that is transcribed and the grade…

Point and linear symbols that represent certain areas of building interiors are discussed in light of their reliability and discriminability if used on tactual maps. A set of "optimally sized" symbols were evaluated with 21 blind observers. (Author/DB)

The Tactile Diagrams Research Project at Loughborough University of Technology (England) developed 164 tactile diagrams for teaching 22 biological themes to blind students. Evaluation of the diagrams found most to be effective when properly introduced to students, and used with supporting text or tapes. (CB)

The question regarding visual imagery and visual perception remain an open issue. Many studies have tried to understand if the two processes share the same mechanisms or if they are independent, using different neural substrates. Most research has been directed towards the need of activation of primary visual areas during imagery. Here we review…

The knowledge visually-impaired people have of the space around them is a subject of great interest to the scientific community. This article describes a school programme and the effect it had on the environmental knowledge of the school where it was carried out. A group of sighted students chose as a project to construct, with the author's help,…

The paper describes a current longitudinal study to examine the speech perception abilities of profoundly hearing-impaired children who use either a cochlear implant or tactile aid. Initial findings indicate large individual differences among subjects with implants and uniformly poor performance by the three subjects with tactile aids. (Author/DB)

This article reviews recent research on perception of tangible pictures in sighted and blind people. Haptic picture naming accuracy is dependent upon familiarity and access to semantic memory, just as in visual recognition. Performance is high when haptic picture recognition tasks do not depend upon semantic memory. Viewpoint matters for the ease…

This project investigated the provision of a set of core tactile and large print diagrams and supporting materials for degree level psychology study, containing diagrams that are central to the majority of UK psychology courses, as an alternative to providing many different bespoke diagrams for individual students. Interviews with 12 blind and…
