Taking a User Centred Design Approach for Designing a System to Teach Sign Language

User Centred Design (UCD) is today a widely accepted philosophy in systems development. UCD stresses the importance of involving and consulting users throughout the design and development of a system; it puts users and their tasks at the centre of the process. The phases of UCD are not universal and there any many interpretations of how UCD might be applied. Despite the wide acceptance of UCD and its recognised value in terms of designing systems which better meet users’ needs, there is little reported research on the application of UCD in actual development contexts. We describe how we employed UCD to develop a system for teaching sign language. We report on how users were involved and contributed to the design of the system at each of the UCD phases. Finally we reflect on what was learned and propose a model for others wishing to take a UCD approac

Breaking The Exclusionary Boundary Between User Experience And Access: Steps Toward Making UX Inclusive Of Users With Disabilities

This research paper points out that we as Designers have failed to come up with a model of UX that would proximate a satisfying user experience for users with disabilities. It underscores the gaps in designer knowledge about disabled bodies. The research paper also draws the attention of the designer community to the limited understanding we presently possess of the disabled people\u27s notions of, and expectations from, satisfying user experiences. It proposes a multi-step process for shifting the focus of design activity from a medical model of accessibility design that retrofits normative designs to the needs of users with disabilities to developing an accessible user experience model (AUX) of design that counts these users as design collaborators, possessors of special knowledge about disabled bodies, and untapped sources of innovative designs that might offer additional design features for all users

A Systematic Analysis of Accessibility Education Within Computing Disciplines

Accessible technologies improve the usability for all users, including 1 billion people in the world who have a disability. Although there is a demand for accessible technologies, there is currently no requirement for universities to integrate this content within the computing curriculum. A systematic comparison of teaching efficacy is important to effectively prepare future computing professionals with the skills to create accessible technologies. This dissertation contains a mixed-methods cross-sectional and longitudinal analysis of undergraduate Software Engineering and Information Technology students’ learning of accessibility. Four teaching conditions were assessed at Rochester Institute of Technology: content lectures, projects, exposure to stakeholders with a disability, and collaboration with a team member who had a disability. Evidence of student learning was obtained through questionnaires, project reports, and interview data. Student learning was quantified by a knowledge of programming techniques, awareness of accessible technologies, and attitudes towards individuals with a disability. The cross-sectional analysis spanned three years (spring 2016-2019), fourteen courses, and seven distinct professors. We found that students in all conditions gained an increased knowledge of implementation methods. Students who were exposed to a stakeholder with a disability obtained significantly higher scores in their prosocial sympathetic attitudes, awareness of accessible technologies, and knowledge of programming techniques following the course. Students in the other conditions obtained significant changes in only a subset of these measures. While students in all conditions obtained significantly higher knowledge scores in the short term, only students who had a project or a team member with a disability sustained significantly higher knowledge scores two years after exposure. In interviews, senior-level students revealed that there were multiple factors outside the classroom that dissuaded them from furthering their learning of accessibility. Students mentioned a lack of person-centered topics in major software development processes (e.g., agile, waterfall) and workplace tasks. Without direct reinforcement, students focused on functional software requirements and expressed that accessibility would only be necessary in select front-end development career paths or domains. While current work in computer accessibility education evaluates learning during, or immediately following, one course, this dissertation provides a systematic comparison of student learning throughout multiple courses and instructors. The findings within this dissertation may be used to inform future curriculum plans and educational initiatives

Accessibility of Vendor-Created Video Tutorials for People with Disabilities

Many video, screencast, webinar, or interactive tutorials are created and provided by vendors for use by libraries to instruct users in database searching. This study investigates whether these vendor-created database tutorials are accessible for people with disabilities to see whether librarians can use these tutorials instead of creating them in-house. Findings on accessibility were mixed. Positive accessibility features and common accessibility problems are described, with recommendations on how to maximize accessibility

How a Diverse Research Ecosystem Has Generated New Rehabilitation Technologies: Review of NIDILRR’s Rehabilitation Engineering Research Centers

Over 50 million United States citizens (1 in 6 people in the US) have a developmental, acquired, or degenerative disability. The average US citizen can expect to live 20% of his or her life with a disability. Rehabilitation technologies play a major role in improving the quality of life for people with a disability, yet widespread and highly challenging needs remain. Within the US, a major effort aimed at the creation and evaluation of rehabilitation technology has been the Rehabilitation Engineering Research Centers (RERCs) sponsored by the National Institute on Disability, Independent Living, and Rehabilitation Research. As envisioned at their conception by a panel of the National Academy of Science in 1970, these centers were intended to take a “total approach to rehabilitation”, combining medicine, engineering, and related science, to improve the quality of life of individuals with a disability. Here, we review the scope, achievements, and ongoing projects of an unbiased sample of 19 currently active or recently terminated RERCs. Specifically, for each center, we briefly explain the needs it targets, summarize key historical advances, identify emerging innovations, and consider future directions. Our assessment from this review is that the RERC program indeed involves a multidisciplinary approach, with 36 professional fields involved, although 70% of research and development staff are in engineering fields, 23% in clinical fields, and only 7% in basic science fields; significantly, 11% of the professional staff have a disability related to their research. We observe that the RERC program has substantially diversified the scope of its work since the 1970’s, addressing more types of disabilities using more technologies, and, in particular, often now focusing on information technologies. RERC work also now often views users as integrated into an interdependent society through technologies that both people with and without disabilities co-use (such as the internet, wireless communication, and architecture). In addition, RERC research has evolved to view users as able at improving outcomes through learning, exercise, and plasticity (rather than being static), which can be optimally timed. We provide examples of rehabilitation technology innovation produced by the RERCs that illustrate this increasingly diversifying scope and evolving perspective. We conclude by discussing growth opportunities and possible future directions of the RERC program

Uncovering the needs for a hybridized interaction design model for sign language learning through experts’ feedback

Nielsen's and Molich's design guidelines have been famously adapted in studies related to the design of interactive products, including for learning environment, and for hearing-impaired learners. In current situation, the learning materials for hearing-impaired learners are lacking in terms of positive interactions that promote two-way communication, partly because they do not apply appropriate design principles appropriately for the users. This affects their stimulation in learning activities. Hence, this paper aims at uncovering the current design principles applied in learning materials for learning sign language for the hearing-impaired learners. Besides an elicitation of literature, a semi-structured interview with the experts in hearing-impaired curricula has been carried out. It reveals that a study needs to urgently be carried out in proposing a heuristics design model that is specifically able to evoke the positive learning experience

Inclusive Intelligent Learning Management System Framework

Machado, D. S-M., & Santos, V. (2023). Inclusive Intelligent Learning Management System Framework. International Journal of Automation and Smart Technology, 13(1), [2423]. https://doi.org/10.5875/ausmt.v13i1.2423The article finds context and the current state of the art in a systematic literature review on intelligent systems employing PRISMA Methodology which is complemented with narrative literature review on disabilities, digital accessibility and legal and standards context. The main conclusion from this review was the existing gap between the available knowledge, standards, and law and what is put into practice in higher education institutions in Portugal. Design Science Research Methodology was applied to output an Inclusive Intelligent Learning Management System Framework aiming to help higher education professors to share accessible pedagogic content and deliver on-line and presential classes with a high level of accessibility for students with different types of disabilities, assessing the uploaded content with Web content Accessibility Guidelines 3.0, clustering students according to their profile, conscient feedback and emotional assessment during content consumption, applying predictive models and signaling students at risk of failing classes according to study habits and finally applying a recommender system. The framework was validated by a focus group to which experts in digital accessibility, information systems and a disabled PhD graduate.publishersversionpublishe
