Current Perspectives on Linux Accessibility Tools for Visually Impaired Users
ЕЛЕКТРОННО СПИСАНИЕ „ИКОНОМИКА И КОМПЮТЪРНИ НАУКИ“, БРОЙ 2, 2019, ISSN 2367-7791, ВАРНА, БЪЛГАРИЯ ELECTRONIC JOURNAL “ECONOMICS AND COMPUTER SCIENCE”, ISSUE 2, 2019, ISSN 2367-7791, VARNA, BULGARIA Current Perspectives on Linux Accessibility Tools for Visually Impaired Users Radka NACHEVA1 1 University of Economics, Varna, Bulgaria [email protected] Abstract. The development of user-oriented technologies is related not only to compliance with standards, rules and good practices for their usability but also to their accessibility. For people with special needs, assistive technologies have been developed to ensure the use of modern information and communication technologies. The choice of a particular tool depends mostly on the user's operating system. The aim of this research paper is to study the current state of the accessibility software tools designed for an operating system Linux and especially used by visually impaired people. The specific context of the considering of the study’s objective is the possibility of using such technologies by Bulgarian users. The applied approach of the research is content analysis of scientific publications, official documentation of Linux accessibility tools, and legal provisions and classifiers of international organizations. The results of the study are useful to other researchers who work in the area of accessibility of software technologies, including software companies that develop solutions for visually impaired people. For the purpose of the article several tests are performed with the studied tools, on the basis of which the conclusions of the study are made. On the base of the comparative study of assistive software tools the main conclusion of the paper is made: Bulgarian visually impaired users are limited to work with Linux operating system because of the lack of the Bulgarian language support. -

An interactive smart search and communication application can support the people at the university campus and Science Park in a number of ways. Primarily, it can strengthen their professional network and establish a responsive eco-system. Therefore, the objective of this research work is to design and implement a unified flexible and adaptable interface. This interface supports an intensive search and communication tool across the university. It would benefit everybody on campus, especially the People with Disabilities (PWDs). (2) Methods: In this project, three main contributions are presented: (A) Assistive Technology (AT) software design and implementation (based on user- and technology-centered design); (B) A wireless sensor network employed to track and determine user’s location; and (C) A novel event behavior algorithm and movement direction algorithm used to monitor and predict users’ behavior and intervene with them and their caregivers when required. -

FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO Personal Medication Advisor Joana Polónia Lobo MASTER IN BIOENGINEERING Supervisor at FhP: Liliana Ferrreira (PhD) Supervisor at FEUP: Aníbal Ferreira (PhD) July, 2013 © Joana Polónia Lobo, 2013 Personal Medication Advisor Joana Polónia Lobo Master in Bioengineering Approved in oral examination by the committee: Chair: Artur Cardoso (PhD) External Examiner: Fernando Perdigão (PhD) Supervisor at FhP: Liliana Ferrreira (PhD) Supervisor at FEUP: Aníbal Ferreira (PhD) ____________________________________________________ July, 2013 Abstract Healthcare faces new challenges with automated medical support systems and artificial intelligence applications for personal care. The incidence of chronic diseases is increasing and monitoring patients in a home environment is inevitable. Heart failure is a chronic syndrome and a leading cause of death and hospital readmission on developed countries. As it has no cure, patients will have to follow strict medication plans for the rest of their lives. Non-compliance with prescribed medication regimens is a major concern, especially among older people. Thus, conversational systems will be very helpful in managing medication and increasing adherence. The Personal Medication Advisor aimed to be a conversational assistant, capable of interacting with the user through spoken natural language to help him manage information about his prescribed medicines. This patient centred approach to personal healthcare will improve treatment quality and efficacy. System architecture encompassed the development of three modules: a language parser, a dialog manager and a language generator, integrated with already existing tools for speech recognition and synthesis. All these modules work together and interact with the user through an Android application. System evaluation was performed through a usability test to assess feasibility, coherence and naturalness of the Personal Medication Advisor. -

Community Notebook
Community Notebook Free Software Projects Projects on the Move Accessibility for computer users with disabilities is one of the noblest goals for Linux and open source software. Vinux, Orca, and Gnome lead the way in Linux accessibility. By Carla Schroder ccessibility of any kind for people with disabilities has a long history of neglect and opposition. The US Rehabilitation Act of 1973 prohibited fed- eral agencies from discriminating on the basis of disability (Sections 501, A503, 504, 508) [1]. Passing a law is one thing; enforcing it is another, and it took years of activism to make any progress. In the 1980s, the Reagan Adminis- tration targeted Section 504 (addressing civil rights for people with disabilities) for de- Lisa Young, 123RF regulation because it was too “burdensome.” Once again advocates organized, and after two years of intensive effort, they succeeded in preserving Section 504. However, years more of Supreme Court fights, legislative battles, and public education efforts had to be won. The culmination of that work was the Americans with Disabilities Act (ADA) of 1990, which addresses some of the basic aspects of everyday life: employ- ment, public accommodations, telecommunications, and government agencies. This law still leaves an awful lot of gaps. Designing for accessibility is more than just bolting on a few aids as an afterthought – it’s a matter of architecture, of design- ing for everyone from the ground up. Accessibility covers a lot of ground, including: • Impaired vision to complete blindness • Impaired hearing to complete deafness • Color blindness • Difficulty or inability to type or use a mouse • Cognitive, learning, or reading problems • Low stamina, difficulty sitting up Talking computers have existed in science fiction for decades, but the world isn’t much closer to having them than it was 10 years ago. -

Evaluating the Accessibility of Digital Audio Workstations for Blind Or Visually Impaired People
Evaluating the Accessibility of Digital Audio Workstations for Blind or Visually Impaired People Gemma Pedrini, Luca Andrea Ludovico a and Giorgio Presti b Laboratorio di Informatica Musicale, Dipartimento di Informatica “Giovanni Degli Antoni”, Universita` degli Studi di Milano, Via G. Celoria 18, Milano, Italy Keywords: Accessibility, Blind or Visually Impaired (BVI), Digital Audio Workstations. Abstract: This paper proposes a methodology to assess the accessibility for blind or visually impaired people of mu- sic production software known as Digital Audio Workstations. The products chosen for the tests are Cockos REAPER, Avid Pro Tools, and Steinberg Cubase, three of the most popular solutions falling in this cate- gory. Both Microsoft Windows and macOS versions were tested, since these two operating systems natively integrate assistive technologies which provide a further layer to be considered. The degree of accessibility was evaluated in relation to the possibility for blind or visually impaired people to invoke key functions and perform basic operations. Finally, a focus group with visually impaired professional music producers was organized in order to assess the proposed evaluation methodology. 1 INTRODUCTION The theme of accessibility in the context of Information Society, also known as e-accessibility Accessibility means enabling as many people as pos- (Klironomos et al., 2006), concerns the integration of sible to use a resource, even when those people’s abil- all users into the Information Society, including peo- ities are limited in some way.
