Implementing an Android Tool for Visually Impaired Students of E-Learning

This article aims to describe the process of learning and development of an educational tool designed for mobile devices (smartphones) with Android technology. In summary, the application was developed based on the virtual learning environment Moodle and aims to develop a learning environment that supports the visually impaired students of e-learning, allowing them to ask questions, discuss and share ideas through forums and use chat rooms in real time. The fundamental purpose of this application is to cooperate with scientific knowledge in the sense that this is a representation of technological advance on the accessibility tools in distance education mode and provide comfort, flexibility and accessibility for the visually impaired students, realizing that education should always be inclusive

Accessibility barriers for users of screen readers in the Moodle learning content management system

In recent decades, the use of the Internet has spread rapidly into diverse social spheres including that of education. Currently, most educational centers make use of e-learning environments created through authoring tool applications like learning content management systems (LCMSs). However, most of these applications currently present accessibility barriers that make the creation of accessible e-learning environments difficult for teachers and administrators. In this paper, the accessibility of the Moodle authoring tool, one of the most frequently used LCMSs worldwide, is evaluated. More specifically, the evaluation is carried out from the perspective of two visually impaired users accessing content through screen readers, as well as a heuristic evaluation considering the World Wide Web Consortium's Authoring Tool Accessibility Guidelines. The evaluation results demonstrate that Moodle presents barriers for screen reader users, limiting their ability to access the tool. One example of accessibility problems for visually impaired users is the frequent inability to publish learning contents without assistance. In light of these results, the paper offers recommendations that can be followed to reduce or eliminate these accessibility barriers.This study has been partially funded by the MA2VICMR (S2009/TIC-1542) research project.Publicad

INTELLIGENT VOICE-BASED E-EDUCATION SYSTEM: A FRAMEWORK AND EVALUATION

Voice-based web e-Education is a technology-supported learning paradigm that allows phone-access of learners to e-Learning web-based applications. These applications are designed mainly for the visually impaired. They are however lacking in attributes of adaptive and reusable learning objects, which are emerging requirements for applications in these domain. This paper presents a framework for developing intelligent voice-based applications in the context of e-Education. The framework presented supports intelligent components such as adaptation and recommendation services. A prototype Intelligent Voice-based E-Education System (iVEES) was developed and subjected to test by visually impaired users. A usability study was carried out using the International Standard Organization’s (ISO) 9241-11 specification to determine the level of effectiveness, efficiency and user satisfaction. Report of our findings shows that the application is of immense benefit, based on the system’s inherent capacity for taking autonomous decision that are capable of adapting to users’ requests

Psychohygienic Aspects Of Training Of Disabled Adolescents With Pathology Of The Vision

The objective of this article is to undertake a literature review to familiarize ourselves with the knowledge base; to summarize information about some psycho-hygienic aspects of teaching and visually impaired adolescents, including features of communication, learning environment, psycho-emotional stress in specialized educational institutions, as well as individual psychological characteristics of personality, emotional and volitional state of visually impaired and general patterns of physiological and psychological characteristics and health of adolescents with vision pathology. To examine the system of security measures in order to optimize the learning environment for the promotion of mental health of the studied contingent and the nature and impact of the learning environment on functional status and health of adolescents with vision pathology. To investigate the impact of current patterns of complex sanitary and regime-organizational factors of training on functional status and health of adolescents with vision pathology. A thorough literature review helps to lay the foundation for a study, and can inspires new research ideas

Psychometric test for blind adults and children, critical issues and perspectives

In literature a paucity of issues to measure cognitive functioning in the blinds is available (Rich, Anderson, 1965; Pichot, 1968; Newland, 1969; Vander Kolk, 1977; Nelson, Joyce, Dias, 2002) but in these reviews it is clear that they are not yet widely available without further support for research and development. This is particularly true for blind children. The purpose of the current study is to provide a proposal version of some of the Visual Performance Subtests adapted to blind children
