PurposeThe purpose of this paper is to explore the issue of access to digital technology by using the lens of accessibility as set forth by the Rehabilitation Act of 1973 and the American Disabilities Act (ADA) of 1990. More specifically, this paper focuses on gamification, considers the needs of all learners, including those who identify as disabled, and raises important inquiries about equity and access to technological instructional materials.Design/methodology/approachJuxtaposing Kapp’s (2012) nine elements of gamification with aspects of accessibility, this paper conceptualizes the challenges and possibilities associated with gamified instructional approaches.FindingsThis paper examines gamification in light of potential barriers that exist as disabled learners navigate online courses that include one or more of the following aspects of gamification – game-based, mechanics, aesthetics, game-thinking, engage, people, motivate action, promote learning, and solve problems. Notably, online courses enhanced with gamification elements present potential access barriers and challenges to learners who identify with auditory, cognitive, neurological, physical, speech, or visual disabilities.Research limitations/implicationsThis paper initiates an important discussion, and as such, it incepts additional investigations into supporting differently abled learners.Practical implicationsBy examining gamification through the lens of accessibility, this paper contributes yet another perspective of teaching, learning, and instructional design.Originality/valueIn addition to socio-economic factors that may preclude one from engaging in a digital play, there is a larger question of how, if at all, gamification is accessible to learners with auditory, cognitive, neurological, physical, speech, or visual disabilities or impairments. This paper raises important questions for educators, education researchers, and game and instructional designers alike to ensure ubiquitous access to gamified digital materials in general, and online, gamified materials in particular.

Digital technologies are an opportunity to overcome disabilities, provided that accessibility is ensured. In this paper, we focus on visual accessibility and the way it is supported in Operating Systems (OS). The significant variability in this support has practical consequences, e.g., the difficulty to recommend or select an OS, or migrate from one OS to another. This suggests building a variability model for OS that would classify them and would serve as a reference. We propose a methodology to build such a variability model with the help of the Formal Concept Analysis (FCA) framework. In addition, as visual accessibility can be divided into several concerns (e.g., zoom, or contrast), we leverage an extension of FCA, namely Relational Concept Analysis. We also build an ontology to dispose of a standardized description of visual accessibility options. We apply our proposal to the analysis of the variability of a few representative operating systems.

This paper addresses the problem of accessibility in geographical web maps. A person with disability cannot use, nowadays, a web map with the same functionality as other users do. This problem creates a huge gap in universal usability, since a wide range of people are left out. This contravenes clearly the principles of the Web, which was created to benefit everyone in any circumstances. In addition, this kind of map would be very useful for people with disabilities, but they cannot take advantage of them due to accessibility problems. In this paper, some of the latest technologies (e.g. PostGIS or SVG) are used in order to provide a geographical web map with accessible features. Since no standard way of doing so exists, our objective is to research, design and implement a system which consists on the essential components to provide accessibility. What we propose is one of the many possible solutions, with some advantages and limitations, for the problem of accessibility on geographical web maps. This proposed solution leads to a discussion about the obtained result and some comments on the current state of the technologies involved in web accessibility.

Abstract Objective This study aimed to investigate the physical activity of children with decreased visual acuity, thereby providing basic data for developing strategies to enhance the physical activity of school-age children. Methods The participants were 1,194 children and 1,194 parents who participated in the 10th Korean Children Panel Survey. Logistic regression analysis was conducted to examine the status of the physical activity of children with decreased visual acuity according to the accessibility of community facilities. Results The mother perceived the accessibility of community facilities as low, children with decreased visual acuity reported 1.20 times shorter over-the-weekend leisure activity time compared with vision-typical children, and they spent 1.41 and 1.33 times shorter on caring for pets and religious activity, respectively. Conclusions To increase the physical activity of children with decreased visual acuity, family-oriented interventions should be provided. It is also important to establish a community environment with enhanced accessibility of community facilities by examining the level of accessibility perceived by parents.

This article aims to propose a strategy taking in consideration the accessibility of each European citizen to information in all its forms especially audio-visual Media and Heritage. It is known that interlingual mediators are playing a huge part in the world of Information and Communication with the involving difficulties of common core theory and training. Moreover, technology can be the ideal tool to enhance accessibility. Thus, mobile phone applications can offer sometimes both audio and visual content to Museum visitors as well as sign language and text. This part of our work clarifies the needs and the values of an adapted methodology for training.In addition, this project gives to inter-cultural mediators the opportunity to work and to research on different applications and software programs in screen-titling, dubbing, re-speaking and screen-titling for the Deaf and Hard of Hearing, audio description and to obtain a training at professional agencies as well as to present a final assistance of quality.

Recently, Shopping malls are introduced in Algerian cities as new commercial structures instead of traditional markets; they become a part of the daily life allowing people to have a new shopping experience. This paper aims to explore the influence of visual accessibility and spatial configuration on the navigation of individuals in a shopping mall through the analysis of Bab-Ezzouar shopping centre. The analysis of spatial and visual patterns adopts space syntax techniques and methods, a survey analysis based on people tracking and a questionnaire is applied to collect data on the shopping centre visitors’ behaviour. The results show that the perception of shopping spaces differs from familiar to unfamiliar visitors, familiar visitors are guided by their shopping habit more than spatial patterns and unfamiliar visitors are influenced by visual patterns of space more than accessibility. Visitors tend to choose the most open spaces that offer maximum visual accessibility more than physical accessibility, they also prefer walking in a straight-line avoiding change of direction. These features can guide designers in their process for better understanding of shopping space.

Objective: The present study examined whether implementing recommendations of Web accessibility guidelines would have different effects on nondisabled users than on users with visual impairments. Background: The predominant approach for making Web sites accessible for users with disabilities is to apply accessibility guidelines. However, it has been hardly examined whether this approach has side effects for nondisabled users. A comparison of the effects on both user groups would contribute to a better understanding of possible advantages and drawbacks of applying accessibility guidelines. Method: Participants from two matched samples, comprising 55 participants with visual impairments and 55 without impairments, took part in a synchronous remote testing of a Web site. Each participant was randomly assigned to one of three Web sites, which differed in the level of accessibility (very low, low, and high) according to recommendations of the well-established Web Content Accessibility Guidelines 2.0 (WCAG 2.0). Performance (i.e., task completion rate and task completion time) and a range of subjective variables (i.e., perceived usability, positive affect, negative affect, perceived aesthetics, perceived workload, and user experience) were measured. Results: Higher conformance to Web accessibility guidelines resulted in increased performance and more positive user ratings (e.g., perceived usability or aesthetics) for both user groups. There was no interaction between user group and accessibility level. Conclusion: Higher conformance to WCAG 2.0 may result in benefits for nondisabled users and users with visual impairments alike. Application: Practitioners may use the present findings as a basis for deciding on whether and how to implement accessibility best.

In the last decades, the general awareness with regard to the topic of universal design (or design for all) has been steadily increasing. As a consequence, more attention is being paid to the requirements of all segments of population (specifically including those with certain perceptual and/or motoric limitations). Nonetheless, additional efforts toward improving pertinent regulations, design practices, and relevant technologies are needed. Specifically, the field of visual accessibility in the built environment has not received the same level of consideration as some other areas of universal design. Given this background, the present contribution reports on the most recent progress made in the course of the ongoing ViDeA research project. This research effort aims primarily at the development of effective means toward supporting the design and implementation of visually accessible solutions in the built environment. Thereby, a central objective is to enhance the mobility of people with sight restriction. Visually impaired people primarily orient themselves based on their residual eyesight. The optimization of lighting solutions represents a highly critical measure toward creating environmental circumstances in which the remaining eyesight can be optimally utilised. The main components of the ViDeA project are as follows: An original set of optometric experiments, the evaluation of a number of use cases and the development of a computational tool for architects and engineers in order to facilitate the evaluation of visual accessibility criteria of projects. The deliverables of the ViDeA project are expected to enhance the quality of visual performance guidelines and augment the capabilities of simulation-based design optimization tools.

A significant number of individuals in the United States report a disability that limits their ability to travel, including many people who are blind or visually impaired (BVI). The implications of restricted transportation result in negative impacts related to economic security, physical and mental health, and overall quality of life. Fully autonomous vehicles (FAVs) present a means to mitigate travel barriers for this population by providing new, safe, and independent travel opportunities. However, current policies governing interactions with the artificial intelligence (AI) ‘at the wheel’ of FAVs do not reflect the accessibility needs articulated by BVI people in the extant literature, failing to encourage use cases that would result in life changing mobility. By reviewing the legislative and policy efforts surrounding FAVs, we argue that the heart of this problem is due to a disjointed, laissez-faire approach to FAV accessibility that has yet to actualize the full benefits of this new transportation mode, not only for BVI people, but also for all users. We outline the necessity for a policy framework that guides the design of FAVs to include the concerns of BVI people and then propose legislative and design recommendations aimed to promote enhanced accessibility, transparency, and fairness during FAV travel.

Visual impairment causes limitations, including mobility. Studies show that there are about 1.3 billion people in the world with some type of visual impairment. Another important factor refers to the need to include these visually impaired people in schools and universities, for autonomy, learning and personal development. Public policies seek to implement measures that ensure the inclusion of people with disabilities, in order to ensure the use of environments in an equal manner. However, these measures are not implemented due to several factors, such as the lack of knowledge of professionals and the lack of financial and technological resources. This research project aimed to evaluate the use of LazarilloApp, a georeferencing application that helps the mobility of people with visual impairment. The tests were conducted at a university in Brazil. Although it has many features and potential, the application was partially effective and efficient, since in only one of the four routes drawn by it the user arrived at the destination. The accessibility problems identified reinforce the need to enable access through structural changes in physical spaces. The results indicate the need to foster the improvement of the functionalities of LazarilloApp and other mobile applications of free access, for the disabled.

Educational, vocational, and social inclusion is one of the fundamental principles that ensure people with disabilities a chance to have as a normal life as possible. In turn, accessibility is one of the most important components of inclusion and could be defined as the right of people with disabilities to benefit of the same products and services as all other community members. According to government data from 2015, in Romania 752 931 were people with disabilities, 60 289 were children and 13.9% had various forms of visual impairment. For these people, any limitation in accessibility means isolation and discrimination. On the other hand, education and new technologies can increase the accessibility of people with visual impairment to quality products and services in society. Therefore, the purpose of this research was the identification of attitude and training level of teachers in the educational process accessibility for students with visual impairment using ICT. The sample consisted of 210 professors who teach in pre-academic learning system in Bihor, Romania and research tool - a questionnaire composed of 76 multiple choice items – it was administered online by the end of 2016. The results of the research show that, even if they want to support inclusion of people with visual impairment using ICT in teaching/learning, most teachers do not have professional skills in that field and do not know how to use educational software or to adapt a scholar curriculum for this category of students.

The aim of this study was to determine the impact of safety-related environmental characteristics in a city park on users’ preferences and whether this impact can be explained by perceived safety. The factors examined were physical and visual accessibility as well as the effectiveness of concealment created by plants in various spatial systems. We used 112 photographs taken in city parks for the study. Studies have shown that visual and physical accessibility varies in terms of impact on preferences and safety—as a result, we tested only visual accessibility and effectiveness. Correlation and regression analyses confirmed that vegetation in a park that obstructs views and can offer concealment reduces our sense of safety. In addition, such vegetation has a negative effect on preference. However, mediation analysis showed that this sense of safety or danger means that dense vegetation (low visual accessibility yet highly effective in offering concealment) is less preferred as a landscape feature. After excluding the impact brought to bear by the sense of safety, the studied features of vegetation had no significant impact on preferences. This means that plants and vegetation layouts of varying densities can be used in completely safe parks and this will probably not adversely affect the feelings of the users.

ABSTRACTAs higher education has increasingly embraced digital technologies, we have been too slow to acknowledge accessibility issues for students with visual disabilities. One of the earliest promises of information and communication technology was increased accessibility to content. In theory, digitized content should be as equally accessible as the printed word on a screen, a braille keyboard, or an audible voice on a speaker. In the majority of educational technology, this promise has gone unfulfilled, and faculty members are largely unaware of the myriad obstacles that students with visual disabilities confront while navigating the technology-rich classroom. The principles of Universal Design in Instruction (UDI) provide guidance for developing curriculum that maximizes accessibility and usability of course content for all learners, including those with disabilities. This article examines the development of political science courses through the lens of UDI.

Purpose Last spring, EBSCO Information Services conducted a usability study with several students with visual impairments. The goal was to understand how these students conduct research and identify areas for improvement of EBSCO Discovery Service™ such that it would meet the needs of all potential users. EBSCO Discovery Service™ provides users with means of accessing all of an institution’s internal (library) and external (database vendors) information resources through a single search. The purpose of this paper is to outline the findings of this research and the applicability to the design of any online resource. Design/methodology/approach Using the Bentley University’s user experience lab to facilitate the study and the Carroll Center for the Blind in Newton, Massachusetts, for recruitment of college students, EBSCO solicited feedback on how students conduct research on the Web in general, as well as their experience using EBSCO’s discovery service. The study involved a structured interview with eight visually impaired students from the Boston area, who had recently been enrolled in a college course. The students were also asked to complete certain tasks using the discovery service and report out as they completed each activity. Findings The findings demonstrated that for the most part, students with visual impairments engaged in research on the Web and within the discovery service in a similar manner to sighted students. They used the same standard search sites, expected the same layout conventions for results’ lists and filters and wanted easily savable full-text documents. Main differences involved their ability to navigate in a similar way to sighted users. Elements that one could skip over quickly as a sighted user were more of a hindrance to those relying on a screen reader. Additionally, improved descriptions for graphics, functions and form fields were noted as opportunities for improvement. For those with low vision, using screen magnifiers, modal boxes and hover features or other unexpected changes on the site proved to be challenging. Research limitations/implications This study focused only on students with visual disabilities. There are many other print disabilities that were not explored such as color blindness, cognitive disabilities or learning disabilities. All the students were in their 20s and had experience conducting research and using library or research-related search sites. Many of the findings highlighted areas of improvement that would benefit all students. Originality/value A study on students with visual disabilities using assistive technologies as they completed research tasks on a discovery system has not been studied before. Guidelines and audits do not provide a complete picture as to whether a website is fully accessible. It is only by working with actual users that insight into what it means to create a truly accessible experience can be gained.

You may not know about the audio-visual material held in the archives at the College: it has not previously been sorted or listed in any way. As a specialist film archivist I looked through the collection, assessed its condition for future accessibility and advised on conservation and preservation issues. The small collections of films seem to have come mostly from the personal collections of fellows of the College, who donated films in their lifetime or after their deaths.

Despite the popular claim that massive open online courses (MOOCs) can democratise educational opportunities, this study suggests that current MOOC platforms are not designed to be accessible and inclusive for learners with disabilities. Our main goals in this study were to identify the needs and barriers that learners with visual impairments face when learning with mobile devices in MOOCs and to make recommendations for designing MOOCs that are more accessible and inclusive. We conducted this study in two phases: a user study (Phase I) and a heuristic walkthrough (Phase II). In Phase I, we conducted a user study with three university students with visual impairments to identify their needs and the barriers to learning that they encounter in mobile MOOC platforms. In Phase II, five evaluators conducted a heuristic walkthrough based on Web Content Accessibility Guidelines 2.0 (World Wide Web Consortium, 2008) to examine the degree of accessibility of a MOOC platform. Overall, the results indicate that serious accessibility issues exist in MOOC platforms, preventing learners with visual impairments from fully participating in learning activities. We conclude this paper by recommending ways to design mobile MOOCs to make them more accessible for learners with visual impairments.

Photographic collections are relatively undeveloped in Japan, although in the last decade a national photographic museum has been established, and other museums have opened departments of photography. Problems of access to collections of photographs of works of art have impeded the study of art history, but the capacity of new technologies to store, and to facilitate the retrieval of, visual images, is beginning to transform the situation.

The paper deals with the topic of making tourist attractions in the regional centre Jihlava accessible to the needs of a specific customer segments – people with physical disabilities, namely wheelchair users and people with visual impairments. This is a relevant topic with both economic and non-economic angle and, at the same time, one that is not sufficiently looked into. In the future the number of visitors with disabilities can be expected to increase, being for the given segment of clients adequately prepared may in fact prove to be a competitive advantage

Introduction: This exploratory study examined how students with visual impairments navigate accessible Word and PDF documents. Methods: Using a combination of video observations and semi-structured interviews, data were collected on participants’ expressed and observed interactions with accessible Word and PDF documents. Results: Using a technique called summative content analysis, four core themes emerged from the findings: useful navigation elements or features (expressed and observed), strategies for navigating accessible documents, barriers to access, and coping strategies. Discussion: The findings suggest practical strategies for training participants to navigate accessible documents. Additionally, they identify the structural elements (i.e., headings, alternative text, etc.) most useful to the study’s participants when navigating accessible documents. Implications for practitioners: As suggested by the findings of this study, universities should implement targeted training initiatives for faculty on basic document accessibility, which could include clearly defining the accessibility features included in a document. Likewise, targeted assistive technology training for students with visual impairments on how to access these elements could increase reading efficiency and reduce cognitive load.

This study focuses on the influence of the degree of visual connections in playrooms on peer interaction between children 21 to 36 months old. In two day care centres, the arrangement of the furniture inside the playrooms were manipulated in order to compare the influence of two contrasting spatial arrangements: a visually open arrangement providing children with a high degree of visual connection within the playroom; and an arrangement with major visual boundaries partitioning the playroom. The findings show that the latter type of spatial arrangement had a negative impact on peer interactions. Conversely, when the spatial arrangement was visually open, children spent more time interacting with peers, and these peer interactions were more affiliative and less conflictual. Furthermore, the positive interactions occurred in longer episodes. These results are discussed as a function of the adaptive flexibility of 2-year-old children's competence in interacting with peers, when they have to cope with an environmental constraint that restricts the visual accessibility to adult caregivers.

Poor accessibility of healthcare facilities is a major barrier for people with disabilities when seeking care. Yet, accessibility is rarely routinely audited. This study reports findings from the first national assessment of the accessibility of primary health care facilities, undertaken in Brazil. A national accessibility audit was conducted by trained staff of all 38,812 primary healthcare facilities in Brazil in 2012, using a 22-item structured questionnaire. An overall accessibility score was created (22 items), and three sub-scales: external accessibility (eight items), internal accessibility (eight items), information accessibility (six items). The main finding is that the overall accessibility score of primary care facilities in Brazil was low (mean of 22, standard deviation (SD) of 0.21, on a 0–100 scale). Accessibility of different aspects of the healthcare facilities was also low, including external space (mean = 31.0, SD = 2.0), internal space (18.9, 1.9) and accessibility features for people with other visual or hearing impairments (6.3, SD = 1.0). Scores were consistently better in the least poor regions of Brazil and in facilities in larger municipality size (indicating more urban areas). In conclusion, large-scale accessibility audits are feasible to undertake. Poor accessibility means that people with disabilities will experience difficulties in accessing healthcare, and this is a violation of their rights according to international and Brazilian laws.
