The Application of Geographic Information Systems to Support Wayfinding for People with Visual Impairments or Blindness

People with visual impairments or legal blindness are relying on differing, comprehensive information utilized for their individual mobility. Increasing the personal mobility of people with disabilities and thereby achieving a self-determined life are major steps toward a more inclusive society. Research and applications on mobility issues of people with visual impairments or blindness mainly focus on technical applications or assistive orientation and navigation devices, and less work is covering the individual needs, e.g., regarding the information required for wayfinding. Moreover, active participation of people with disabilities in research and development is still limited. ways2see offers a new online application to support individual mobility in context of pre-trip planning for people with visual impairments or blindness based on a Geographic Information System (GIS). Obstacles, barriers, landmarks, orientation hints, and directions for wayfinding are generated by user profiles. The underlying network for GIS analysis is designed as pedestrian network. This individually coded network approach integrates sidewalks and different types of crossings and implements various orientation and navigation attributes. ways2see integrates three research realms: firstly, implementing a participative and transdisciplinary research design; secondly, integrating personalized information aligned with the individual user needs; and thirdly, presenting result of GIS analysis through an accessible designed user interface

Mapping Access: Digital Humanities, Disability Justice, and Sociospatial Practice

New digital projects use geographic information systems (GIS) and crowdsourcing applications to gather data about the accessibility of public spaces for disabled people. While these projects offer useful tools, their approach to technology and disability is often depoliticized. Compliance-based maps take disability for granted as medical impairment and do not consider mapping as a humanistic and activist practice. This essay draws on digital humanities theories of "thick mapping" and critical disability theories of public citizenship to offer critical accessibility mapping as an alternative to compliance-focused mapping. Using Mapping Access as a case study, I frame digital mapping as a question-generating device, a site of narrative praxis, rather than mere data visualization. I argue that critical accessibility mapping offers a digital humanities-informed model of "sociospatial practice," with several distinct benefits: it recognizes marginalized experts; redefines the concepts of data, crowdsourcing, and public participation; offers new stories about disability and public belonging; and materializes the principles of disability justice, an early twentieth-century movement emphasizing intersectionality and collective access

Ensuring accessibility of electronic information resources for visually impaired people : the need to clarify concepts such as visually impaired

PURPOSE – The paper addresses the importance of clarifying terminology such as visually impaired and related terms before embarking on accessibility studies of electronic information resources in library contexts. Apart from briefly defining accessibility, the paper attempts to address the lack of in-depth definitions of terms such as visually impaired, blind, partially sighted, etc. that has been noted in the literature indexed by two major Library and Information Science (LIS) databases. The purpose of this paper is to offer a basis for selecting participants in studies of accessibility of electronic information resources in library contexts and to put discussions of such studies in context. DESIGN/METHODOLOGY/APPROACH – Clarification of concepts concerning visual impairment following a literature survey based on searching two major databases in LIS. To put the discussion in context accessibility is also briefly defined. FINDINGS – Although visually impaired and a variety of related terms such as blind, partially sighted, visually disabled, etc. are used in the LIS literature, hardly any attempt is made to define these terms in depth. This can be a serious limitation in web and electronic accessibility evaluations and the selection of participants. PRACTICAL IMPLICATIONS – Clearly distinguishing between categories of visually impaired people and the ability of sight of participants is important when selecting participants for studies on accessibility for visually impaired people, e.g. the accessibility evaluation of web sites, digital libraries and other electronic information resources. ORIGINALITY/VALUE – The paper can make a contribution to the clarification of terminology essential for the selection of participants in accessibility studies, as well as enriching the literature on accessibility for visually impaired people in the context of LIS.http://www.emeraldinsight.com/0737-8831.htmhb201

Visual Impairment and Blindness

Blindness and vision impairment affect at least 2.2 billion people worldwide with most individuals having a preventable vision impairment. The majority of people with vision impairment are older than 50 years, however, vision loss can affect people of all ages. Reduced eyesight can have major and long-lasting effects on all aspects of life, including daily personal activities, interacting with the community, school and work opportunities, and the ability to access public services. This book provides an overview of the effects of blindness and visual impairment in the context of the most common causes of blindness in older adults as well as children, including retinal disorders, cataracts, glaucoma, and macular or corneal degeneration
