Study of conditions of use of E-services accessible to visually disabled persons  [PDF]
Marc-Eric Bobiller-Chaumon,Michel Dubois,Fran?oise Sandoz-Guermond
Computer Science , 2007,
Abstract: The aim of this paper is to determine the expectations that French-speaking disabled persons have for electronic administrative sites (utility). At the same time, it is a matter of identifying the difficulties of use that the manipulation of these E-services poses concretely for blind people (usability) and of evaluating the psychosocial impacts on the way of life of these people with specific needs. We show that the lack of numerical accessibility is likely to accentuate the social exclusion of which these people are victim by establishing a numerical glass ceiling.

Abstract: Although the world’s attention has on several occasions been turned to the plight of the vision impaired, there has been no international copyright instrument that specifically provides for limitations or exceptions to copyright for their benefit. Such an instrument becomes imperative amidst the grow- ing number of persons in this category and the need to facilitate their access to information that will give them the opportunity to participate in public affairs. Brazil, Ecuador, Paraguay, and Mexico (Brazilian group) seek to fill this gap by submitting to the WIPO’s Standing Committee on Copyright and Related Rights a draft treaty for Improved Access for Blind, Visually Impaired and Other Reading Disabled Persons. How- ever, this proposal has generated a lot of reactions, resulting in three other such proposals being submit- ted to WIPO for deliberations. Copyright owners have also opposed the treaty. Amidst these reactions, this work seeks to analyze the compatibility of the Brazilian group’s proposal with the TRIPS three-step test, which has enjoyed a great deal of international recognition since its inclusion in the Berne Convention. It also seeks to find its compatibility with EU copyright law as harmonized in the Directive 2001/29/EC. In the end, we conclude that the proposed treaty is in harmony with the three-step test, and though it has some variations from the EU Copyright Directive, it nonetheless shares some underlying objectives with the Directive and does not radically depart from what prevails in several EU member states.
Design of a Mobile Face Recognition System for Visually Impaired Persons  [PDF]

Computer Science , 2015,
Abstract: It is estimated that 285 million people globally are visually impaired. A majority of these people live in developing countries and are among the elderly population. One of the most difficult tasks faced by the visually impaired is identification of people. While naturally, voice recognition is a common method of identification, it is an intuitive and difficult process. The rise of computation capability of mobile devices gives motivation to develop applications that can assist visually impaired persons. With the availability of mobile devices, these people can be assisted by an additional method of identification through intelligent software based on computer vision techniques. In this paper, we present the design and implementation of a face detection and recognition system for the visually impaired through the use of mobile computing. This mobile system is assisted by a server-based support system. The system was tested on a custom video database. Experiment results show high face detection accuracy and promising face recognition accuracy in suitable conditions. The challenges of the system lie in better recognition techniques for difficult situations in terms of lighting and weather.
Accessible Online Health Promotion Information for Persons with Disabilities
Smeltzer, S., Zimmerman, V., Frain, M., DeSilets, L., Duffin, J
Online Journal of Issues in Nursing , 2003,
Abstract: Online health promotion materials have great potential to reach persons with disabilities and provide valuable information to this vulnerable population. While health promotion efforts are important for everyone, they are crucial for individuals with disabilities. Yet information needed to support these efforts is often presented in such a way that its access is limited or its content is inappropriate for this population. Whether designing or selecting online materials for individuals with disabilities, nurses can benefit from knowledge about strategies to make web sites more accessible or to assess the accessibility of existing web sites. The task of providing health promotion information to women with disabilities was undertaken as part of the Health Promotion for Women with Disabilities Project at Villanova University’s College of Nursing. A web site was created as one method of providing information. This paper presents strategies that are used to make this site accessible.
Methods and Techniques for the Access of Persons With Visual Impairments to Handbooks and Textbooks  [PDF]
Informatica Economica Journal , 2008,
Abstract: The transformation of learning materials in an accessible format for blind students allows them to access texts and graphics. This access was not possible before considering the past technologies. The Daisy format represents an accessibility standard that permits the visually impaired person to listen an audio book as a person without disability. In this way, the visually impaired person can listen the audio book according to its content and/or pages. The usage of this format enables to develop new approaches in the process of teaching and learning, not only for visually impaired students but also for visually impaired teachers. The Daisy format proved to be efficient in the educational area also for children with learning difficulties. Studies concerned with efficiency of Daisy book.
Voice Operated Outdoor Navigation System For Visually Impaired Persons  [PDF]
Somnath koley, Ravi Mishra
International Journal of Engineering Trends and Technology , 2012,
Abstract: —Blind People uses white canes to aid in obstacle detection & avoidance. Guide dogs can also be of limited aid for finding the way to a remote location. So our goal is to create a portable, simple less costly system that will allow Blind peoples to travel through familiar and unfamiliar environments without the aid of guides. Several guidance system has been developed for vision impaired people, but these systems tends to be expensive, also make use of a client server approach. This Navigation system consists of two distinct components: sensing of the immediate environment for blind people to travel (e.g., obstacles and hazards) and navigating to remote destinations beyond the immediately perceptible environment. The paper described here focused on the development and evaluation of a Navigation system that makes use of GPS (the Global Positioning System), voice and ultrasonic sensor for obstacle detection.
Interactive audio-tactile maps for visually impaired people  [PDF]
Anke Brock,Christophe Jouffrais
Computer Science , 2015, DOI: 10.1145/2850440.2850441
Abstract: Visually impaired people face important challenges related to orientation and mobility. Indeed, 56% of visually impaired people in France declared having problems concerning autonomous mobility. These problems often mean that visually impaired people travel less, which influences their personal and professional life and can lead to exclusion from society. Therefore this issue presents a social challenge as well as an important research area. Accessible geographic maps are helpful for acquiring knowledge about a city's or neighborhood's configuration, as well as selecting a route to reach a destination. Traditionally, raised-line paper maps with braille text have been used. These maps have proved to be efficient for the acquisition of spatial knowledge by visually impaired people. Yet, these maps possess significant limitations. For instance, due to the specificities of the tactile sense only a limited amount of information can be displayed on a single map, which dramatically increases the number of maps that are needed. For the same reason, it is difficult to represent specific information such as distances. Finally, braille labels are used for textual descriptions but only a small percentage of the visually impaired population reads braille. In France 15% of blind people are braille readers and only 10% can read and write. In the United States, fewer than 10% of the legally blind people are braille readers and only 10% of blind children actually learn braille. Recent technological advances have enabled the design of interactive maps with the aim to overcome these limitations. Indeed, interactive maps have the potential to provide a broad spectrum of the population with spatial knowledge, irrespective of age, impairment, skill level, or other factors. To this regard, they might be an efficient means for providing visually impaired people with access to geospatial information. In this paper we give an overview of our research on making geographic maps accessible to visually impaired people.
Tactile graphic: the possible form of information and inclusion of the visually impaired  [cached]
Leia de Andrade,Fernando Luiz de Paula Santil
Educa??o : Teoria e Prática , 2011,
Abstract: Although the graphics are present in the textbooks, these are not so accessible to the blind. In this case you need to generate them in high relief to be allowed to read through the tactile sense. For research in the development of tactile graphics with students in 5th grade the urban perimeter of Maringá (PR), drew on the Piaget’s theory, who directed the evaluation of the cognitive development of students in the tasks, and also semiology graphics proposed by Bertin, who helped design treatment information for this production. In order to show the importance of tactile graphics for visually impaired students, which are inserted into the regular classroom, it was evaluated the techniques of construction and production of tactile graphic, and the steps of reading material. The results show that the graphs constructed instigate exploration, as much as it was a favor to tactile perception. It is necessary to respect the "living space" of the chart, in the case indicated by the distance between the hands. Regarding reading, the difficulties encountered were the identification of form, the notion of scale and coordinate system.

Abstract: The inclusion process should guarantee teaching and learning of all students including those with special needs. Currently, didactical materials with focus in attending blind and visually impaired students are still in need, especially those for teaching Biology complex themes (e.g. Arthropods). The purpose of this work is to describe the production and the in loco test of a kit containing an accessible, tactile, didactical and inclusive material about Arthropods targeting this public, which allows to explore the biotechnological potential of these animals. The kit was constructed with affordable materials approached in two- and three-dimensional perspectives. We tested it with seven students with visual deficiency from a Brazilian public school. To verify the efficiency of the material, we applied evaluative questionnaires regarding the theme pre- and post-periods from using the material. The results revealed that the use of this didactical material helps the blind and visually impaired student to understand the complexity of Arthropods anatomy and its morphological characterization to apply for biotechnology purposes.

Abstract: The objective of the study is to find out the parental anxiety among the visually impaired children and normal children. In the present investigation, 120 visually impaired children and normal children and their parents were selected. Equal number of 60 subjects belonged to the group of visually impaired children and normal children. Of which 30 were males and females in each group. Both fathers and mothers of these children were selected for the present study. The results of the present study revealed that parents of both male and female visually impaired children experienced more anxiety than the parents of normal children. Gender did not have any effect on parental anxiety among visually impaired children and normal children.
