Responsive inclusive design (RiD): a new model for inclusive software development.

The design and development of technological solutions based on software for all types of people, including people with disabilities, is still a pending issue in most software application development projects today. Situations like the 2020 pandemic drastically reflect how people with disabilities tend to be left outside the application design and construction guidelines. There are multiple initiatives and previous works that advocate user involvement from the beginning of the project; however, in this work, we go a step further by presenting a model for designing and constructing software applications (RiD—Responsive inclusive Design) defined for inclusive software. RiD extends the involvement of the user with disabilities to the entire software life cycle, in different roles, and taking into account the changing nature of the user profile in the evolution of the product. This article also presents the EDICO case study, an accessible and inclusive scientific editor for the Spanish National Organization of the Blind (ONCE), which was successfully implemented applying the RiD principles.post-print1229 k

Teaching Visually Impaired College Students in Introductory Statistics

Instructors of postsecondary classes in statistics rely heavily on visuals in their teaching, both within the classroom and in resources like textbooks, handouts, and software, but this information is often inaccessible to students who are blind or visually impaired (BVI). The unique challenges involved in adapting both pedagogy and course materials to accommodate a BVI student may provoke anxiety among instructors teaching a BVI student for the first time, and instructors may end up feeling unprepared or “reinventing the wheel.” We discuss a wide variety of accommodations inside and outside of the classroom grounded in the empirical literature on cognition and learning and informed by our own experience teaching a blind student in an introductory statistics course

Supporting braille readers in reading and comprehending mathematical expressions and equations

International audienceBraille readers create an overview of an expression by reading one braille character after another or listening to a voice saying the expression or equation aloud. The specific skills and knowledge that mathematics teachers need to assist this complicated process are often lacking. The purpose of this study was to investigate the effect of an intervention consisting of a course focused on braille display support in combination with Text-To-Speech synthesizer for mathematics teachers on the mathematical performances of braille readers. A quasi-experimental approach was taken to answer this question. Five teachers of an experimental group received the intervention whereas the teacher of the control group did not. Both the experimental group, consisting of 10 braille readers, and the control group, consisting of five braille readers, took a pre- and post-test. The results indicated that there was a very small positive effect of the intervention

@Science: a network about science accessibility for university students

At present, visually impaired students are strongly discouraged to attend university scientific studies, especially because of the lack of scientific resources fully accessible through assistive technologies, the difficulty to attend scientific university lectures based on explanations employing transparencies with mathematical expressions as well as graphical representations and the tools to work on mathematical expressions, which are often partially usable or incomplete for advanced subjects. Furthermore, the variety all over Europe of national braille codes to represent mathematical expressions and the language dependence of audio books recorded by human readers make difficult a cross country exchange of knowledge and resources. Some universities have been working on the improvement of assistive technologies in science learning for many years and they have collected best experiences, tools, accessible scientific resources and effective and efficient methods. Unfortunately, up to now many of these best practices and educational resources haven't got widespread all over Europe. In order to share knowledge among universities about science accessibility by visually impaired people and to produce guidelines and to document best practices, the @Science thematic network was established. It is supported for two years by the European Union eContent- Plus Programme. It involves six founding members from five European countries: Italy, Austria, Slovakia, Belgium and France. In the project lifetime, collaboration actions will be undertaken so as to involve in the thematic network other universities, software and hardware manufacturers, publishers, associations for visually impaired persons and students themselves. In so doing, each group will contribute with its experience and will gain knowledge from other experiences. Moreover, the guidelines and best practices will be the result of a two years exchange of knowledge among experts and end users. At first, this paper will introduce the main barriers which affect blind students in going through scientific studies. Then, it will present the objectives and the methodology of the @Science network

Math in the Dark: Tools for Expressing Mathematical Content by Visually Impaired Students

Blind and visually impaired students are under-represented in the science, technology, engineering, and mathematics disciplines of higher education and the workforce. This is due primarily to the difficulties they encounter in trying to succeed in mathematics courses. While there are sufficient tools available to create Braille content, including the special Nemeth Braille used in the U.S. for mathematics constructs, there are very few tools to allow a blind or visually impaired student to create his/her own mathematical content in a manner that sighted individuals can use. The software tools that are available are isolated, do not interface well with other common software, and may be priced for institutional use instead of individual use. Instructors are unprepared or unable to interact with these students in a real-time manner. All of these factors combine to isolate the blind or visually impaired student in the study of mathematics. Nemeth Braille is a complete mathematical markup system in Braille, containing everything that is needed to produce quality math content at all levels of complexity. Blind and visually impaired students should not have to learn any additional markup languages in order to produce math content. This work addressed the needs of the individual blind or visually impaired student who must be able to produce mathematical content for course assignments, and who wishes to interact with peers and instructors on a real-time basis to share mathematical content. Two tools were created to facilitate mathematical interaction: a Nemeth Braille editor, and a real-time instant messenger chat capability that supports Nemeth Braille and MathML constructs. In the Visually Impaired view, the editor accepts Nemeth Braille input, displays the math expressions in a tree structure which will allow sub-expressions to be expanded or collapsed. The Braille constructs can be translated to MathML for display within MathType. Similarly, in the Sighted view, math constructs entered in MathType can be translated into Nemeth Braille. Mathematical content can then be shared between sighted and visually impaired users via the instant messenger chat capability. Using Math in the Dark software, blind and visually impaired students can work math problems fully in Nemeth Braille and can seamlessly convert their work into MathML for viewing by sighted instructors. The converted output has the quality of professionally produced math content. Blind and VI students can also communicate and share math constructs with a sighted partner via a real-time chat feature, with automatic translation in both directions, allowing VI students to obtain help in real-time from a sighted instructor or tutor. By eliminating the burden of translation, this software will help to remove the barriers faced by blind and VI students who wish to excel in the STEM fields of study

Aprendizagem Digital: Modelos diferenciados de ensino utilizando TICs para alunos com problemas de visão – Boas práticas: Jogando entre 1 a 10

The idea of inclusion encourages an inclusive, open-door school. By adapting formal instruction to standard instruction that is acceptable for everyone while taking into account the requirements, quirks, skills, interests, and experiences of each student, the use of ICTs aids in this direction. One such group is the visually challenged, whose inclusion in general education classes is made possible with the use of ICTs. In the current study, a method of individualized education in the field of mathematics is developed and put into practice, allowing all students-visually impaired or not-to master the mathematical operation of adding to the first ten at their own speed and time. Results show that differentiated instruction improves students' ability to understand mathematical operations: ADDITION from 1 to 10.La idea de inclusión fomenta una escuela inclusiva y de puertas abiertas. Al adaptar la instrucción formal a la instrucción estándar aceptable para todos, teniendo en cuenta los requisitos, peculiaridades, habilidades, intereses y experiencias de cada estudiante, el uso de las TIC ayuda en esta dirección.

Instructional eLearning technologies for the vision impaired

The principal sensory modality employed in learning is vision, and that not only increases the difficulty for vision impaired students from accessing existing educational media but also the new and mostly visiocentric learning materials being offered through on-line delivery mechanisms. Using as a reference Certified Cisco Network Associate (CCNA) and IT Essentials courses, a study has been made of tools that can access such on-line systems and transcribe the materials into a form suitable for vision impaired learning. Modalities employed included haptic, tactile, audio and descriptive text. How such a multi-modal approach can achieve equivalent success for the vision impaired is demonstrated. However, the study also shows the limits of the current understanding of human perception, especially with respect to comprehending two and three dimensional objects and spaces when there is no recourse to vision

Research to Market Transition of Mobile Assistive Technologies for People with Visual Impairments

Mobile devices are accessible to people with visual impairments and hence they are convenient platforms to support assistive technologies. Indeed, in the last years many scientifc contributions proposed assistive applications for mobile devices. However, few of these solutions were eventually delivered to end-users, depriving people with disabilities of important assistive tools. The underlying problem is that a number of challenges need to be faced for transitioning assistive mobile applications from research to market. This contribution reports authors\u2019 experience in the academic research and successive distribution of three mobile assistive applications for people with visual impairment. As a general message, we describe the relevant characteristics of the target population, analyze different models of transition from academic research to end-users distribution and show how the transitioning process has a positive impact on research
