The VIVID model : accessible IT e-learning environments for the vision impaired

Sighted learners and vision impaired learners experience different problems when accessing e-learning environments. Web designers use complex visual images and interactive features which learners with vision impairment are unable to access. Learners with vision impairment must rely on assistive technologies to acquire the information they are seeking. Vision impaired learners must have conversion facilities to translate the contents of these displays into readable and accessible formats.This research identifies problems faced by learners with vision impairment and demonstrates how e-learning environments must be modified to ensure success. The most significant problems are the lack of accessibility to teaching materials and an inability to participate in the learning experience to the same extent as sighted learners. Learning materials designed for sighted learners are often unsuited to those with vision impairment. Frequently, text provided is too small and unable to be altered; colour graphics are of little value unless accompanied by text or audio description and interactive Web sites present numerous challenges in navigation. Most courses are designed for sighted learners and learners with vision impairment struggle to maintain the required timeframe because of difficulties in reading texts and documents, completing assignments and sourcing reference materials due to their inaccessible formats and presentation.These problems result in lower academic achievement for vision impaired learners, which in turn lead to a lack of choices in employment opportunities. Learning environments for people with vision impairment need specific consideration in design and implementation. This ensures that the learning materials meet their needs and allow maximum accessibility so that the learners can achieve the same outcomes as their sighted peers.There is a small number of existing models to assist the design of e-learning sites for people with a disability. Kelley’s holistic model (2005) and Seale’s contextualised model (2006) are designed for people with disabilities in general and not specifically for those with vision impairment. Lazar’s Web accessibility integration model (2004) does not take into account the importance of social elements. Prougestaporn’s WAVIP model, (2010) whilst it has generic guidelines, the model is limited in its scope.Venable’s Design Science Research method was chosen to investigate the specific problems faced by vision impaired learners enrolled in IT e-learning courses. The characteristics of approximately one hundred adult vision impaired learners were investigated using two case study environments. The data were collected by observation and semi-structured interviews. Additionally, data were collected from these same learners to identify their specific needs in a Web-based learning situation. Accessibility needs were also identified and analysed. These activities involved the Problem Diagnosis stage in the Design Science Research model. Accessibility guidelines and legal and statutory requirements from several sources were also investigated. The components needed to deliver an effective, fully accessible IT curriculum in two Web-based e-learning environments for the vision impaired was then identified.Information was compiled from studying two learning environments for the vision impaired. Data instruments used in this phase were observations and semi-structured interviews with vision impaired learners and teachers. These activities involved the Problem Diagnosis and Theory Building stages of the Venable model. The relationships between the characteristics and needs of the learner, and the components of the learning environment for an Information and Communications and Technology (ICT) curriculum were analysed and then synthesised to build a conceptual model of an effective Web-based e-learning environment for the vision impaired.A new theoretical model, the Vision Impaired using Virtual IT Discovery (VIVID) was then developed. This holistic framework takes into account the specific needs of vision impaired learners. It also includes a social element which vision impaired learners identified as being extremely important to the success of their learning. This activity involved both the Technology Design/Invention state and the Theory Building stage in the Venable model.An evaluation was carried out by a focus group of eight experts in the field of accessible and e-learning course design and the model was then modified to incorporate their suggestions.The resulting model is a high level, comprehensive conceptual model that can be applied in differing pedagogical environments relating to IT education for adult learners with vision disabilities. It provides a framework to guide education managers, instructional designers and developers who are creating accessible IT e-learning environments for the vision impaired.Whilst this model relates only to the IT area, further research could extend its use to other curriculum areas and to those learners with multiple disabilities

TOURISM FOR ALL: AN INNOVATIVE APPROACH FORENHANCING WELL-BEING OF SPECIAL NEEDSCASE STUDY (ISLAMIC CAIRO –HISTORICAL CITY)

Cities are being increasingly recognized and valued for their contributions to the quality of life of their citizens. Urban environments provide enormous variety of physical and cultural components. Due to social and demographic changes, there is an increase of people with disabilities all over the world. According to UNWTO, people with disabilities represent 2 billion persons or 15 % of the world population .Over the years, persons with disabilities has faced barriers to realizing their right to participate in life in general and in cultural life in particular due to inaccessibility of cultural programs, health problems, and lack of services. Persons with disabilities on average as a group are more likely to experience adverse socio economic outcomes such as poorer health less education and Lower level of employment. The researchers will highlight on how accessibility and accessible tourism can improve and enhance the quality of services, promoting social justice through ensuring healthy and safe life for disabled persons. At the same time from Human right perspective they have the right to live, enjoy and participate in all aspects of life. The research was conducted by using the anthropological qualitative approach; i.e. in-depth interviews and different types of observations. In conclusion, therefore the study advocates the right of Special needs to live and enjoy their lives; to enjoy visiting their cultural heritage sites in an accessible way; and to access museums, galleries, hotels easily.

Engaging older adults with age-related macular degeneration in the design and evaluation of mobile assistive technologies

Ongoing advances in technology are undoubtedly increasing the scope for enhancing and supporting older adults’ daily living. The digital divide between older and younger adults, however, raises concerns about the suitability of technological solutions for older adults, especially for those with impairments. Taking older adults with Age-Related Macular Degeneration (AMD) – a progressive and degenerative disease of the eye – as a case study, the research reported in this dissertation considers how best to engage older adults in the design and evaluation of mobile assistive technologies to achieve sympathetic design of such technologies. Recognising the importance of good nutrition and the challenges involved in designing for people with AMD, this research followed a participatory and user-centred design (UCD) approach to develop a proof–of–concept diet diary application for people with AMD. Findings from initial knowledge elicitation activities contribute to the growing debate surrounding the issues on how older adults’ participation is initiated, planned and managed. Reflections on the application of the participatory design method highlighted a number of key strategies that can be applied to maintain empathic participatory design rapport with older adults and, subsequently, lead to the formulation of participatory design guidelines for effectively engaging older adults in design activities. Taking a novel approach, the final evaluation study contributed to the gap in the knowledge on how to bring closure to the participatory process in as positive a way as possible, cognisant of the potential negative effect that withdrawal of the participatory process may have on individuals. Based on the results of this study, we ascertain that (a) sympathetic design of technology with older adults will maximise technology acceptance and shows strong indicators for affecting behaviour change; and (b) being involved in the design and development of such technologies has the capacity to significantly improve the quality of life of older adults (with AMD)

Accessibility of Health Data Representations for Older Adults: Challenges and Opportunities for Design

Health data of consumer off-the-shelf wearable devices is often conveyed to users through visual data representations and analyses. However, this is not always accessible to people with disabilities or older people due to low vision, cognitive impairments or literacy issues. Due to trade-offs between aesthetics predominance or information overload, real-time user feedback may not be conveyed easily from sensor devices through visual cues like graphs and texts. These difficulties may hinder critical data understanding. Additional auditory and tactile feedback can also provide immediate and accessible cues from these wearable devices, but it is necessary to understand existing data representation limitations initially. To avoid higher cognitive and visual overload, auditory and haptic cues can be designed to complement, replace or reinforce visual cues. In this paper, we outline the challenges in existing data representation and the necessary evidence to enhance the accessibility of health information from personal sensing devices used to monitor health parameters such as blood pressure, sleep, activity, heart rate and more. By creating innovative and inclusive user feedback, users will likely want to engage and interact with new devices and their own data

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

Exploring the accessibility of deformed digital heritage models

The concept of accessibility has been examined by the scientific community in various fields such as education, health care, social inclusion, disabilities, transport, and tourism. Regarding heritage, the European Commission’s efforts toward accessible cultural heritage are highlighted, along with the use of digitisation and modelling technologies for complex heritage shapes. Thus, this chapter explores relevant scientific research into the accessibility of digital heritage models that represent the assets’ real condition, that is, as-is or as-built models produced using advanced digitisation and modelling technologies. The study emphasises the importance of both physical and semantic aspects of heritage conservation and the need for public awareness and cooperation toward the aimed accessibility. The methodology addresses the search for publications in Scopus and Web of Science and their filtering based on inclusion and exclusion criteria to ensure documents related to the accessibility of deformed digital heritage models are considered. The research concludes that creating accessible deformed digital heritage models is crucial for inclusion and participation from the public and stakeholders, and while some studies achieve accurate as-built geometries and accessibility, there is room for improvement

Designing a New Tactile Display Technology and its Disability Interactions

People with visual impairments have a strong desire for a refreshable tactile interface that can provide immediate access to full page of Braille and tactile graphics. Regrettably, existing devices come at a considerable expense and remain out of reach for many. The exorbitant costs associated with current tactile displays stem from their intricate design and the multitude of components needed for their construction. This underscores the pressing need for technological innovation that can enhance tactile displays, making them more accessible and available to individuals with visual impairments. This research thesis delves into the development of a novel tactile display technology known as Tacilia. This technology's necessity and prerequisites are informed by in-depth qualitative engagements with students who have visual impairments, alongside a systematic analysis of the prevailing architectures underpinning existing tactile display technologies. The evolution of Tacilia unfolds through iterative processes encompassing conceptualisation, prototyping, and evaluation. With Tacilia, three distinct products and interactive experiences are explored, empowering individuals to manually draw tactile graphics, generate digitally designed media through printing, and display these creations on a dynamic pin array display. This innovation underscores Tacilia's capability to streamline the creation of refreshable tactile displays, rendering them more fitting, usable, and economically viable for people with visual impairments
