A FRAMEWORK FOR INTELLIGENT VOICE-ENABLED E-EDUCATION SYSTEMS
Although the Internet has received significant attention in recent years, voice is still the most convenient and natural way of communicating between human to human or
human to computer. In voice applications, users may have different needs which will require the ability of the system to reason, make decisions, be flexible and adapt to
requests during interaction. These needs have placed new requirements in voice application development such as use of advanced models, techniques and methodologies which take into account the needs of different users and environments. The ability of a system to behave close to human reasoning is often mentioned as one of the major requirements for the development of voice applications.
In this paper, we present a framework for an intelligent voice-enabled e-Education application and an adaptation of the framework for the development of a prototype Course Registration and Examination (CourseRegExamOnline) module. This study is a preliminary report of an ongoing e-Education project containing the following modules: enrollment, course registration and examination, enquiries/information, messaging/collaboration, e-Learning and library.
The CourseRegExamOnline module was developed using VoiceXML for the voice user interface(VUI), PHP for the web user interface (WUI), Apache as the middle-ware and MySQL database as back-end. The system would offer dual access modes using the VUI and WUI.
The framework would serve as a reference model for developing voice-based e-Education applications. The e-Education system when fully developed would meet the
needs of students who are normal users and those with certain forms of disabilities such as visual impairment, repetitive strain injury (RSI), etc, that make reading and
writing difficult
Embedding accessibility and usability: considerations for e-learning research and development projects
This paper makes the case that if e‐learning research and development projects are to be successfully adopted in real‐world teaching and learning contexts, then they must effectively address accessibility and usability issues; and that these need to be integrated throughout the project. As such, accessibility and usability issues need to be made explicit in project documentation, along with allocation of appropriate resources and time. We argue that accessibility and usability are intrinsically inter‐linked. An integrated accessibility and usability evaluation methodology that we have developed is presented and discussed. The paper draws on a series of mini‐case studies from e‐learning projects undertaken over the past 10 years at the Open University

Language engineering - a champion for European culture
Language is key to culture. It is a direct cultural medium as well as a means of recording and providing access to non-lingual elements of culture. Language is also fundamental to a sense of cultural identity. For this reason, it is vital, in a changing Europe, that we preserve the multi-lingual character of our society in order to move successfully towards closer co-operation at a political, economic, and social level.
Language engineering is the application of knowledge of language to the development of computer software which can recognise, understand, interpret, and generate human language in all its forms.
The paper provides a high level view of the ‘state of the art’ in language engineering and indicates ways in which it will have a profound impact on our culture in the future. It shows how advances in language engineering are an important aid in maintaining cultural diversity in a multi-lingual European society, while enabling the development of social cohesion across cultural and national divides. It addresses issues raised by the prospect of the Multi-lingual Information Society, including education, human communication with technology and information management, as well as aspects of digital cities such as tele-presence in digital libraries, virtual art galleries and electronic museums. The paper raises the issue of language as a factor in cultural domination, showing the contribution that language engineering can make towards countering it.
The paper also raises a number of controversial issues concerning the likely benefits arising from the ways in which language is likely to influence the culture of Europe
UEFI BIOS Accessibility for the Visually Impaired
People with some kind of disability face a high level of difficulty for
everyday tasks because, in many cases, accessibility was not considered
necessary when the task or process was designed. An example of this scenario is
a computer's BIOS configuration screens, which do not consider the specific
needs, such as screen readers, of visually impaired people. This paper proposes
the idea that it is possible to make the pre-operating system environment
accessible to visually impaired people. We report our work-in-progress in
creating a screen reader prototype, accessing audio cards compatible with the
High Definition Audio specification in systems running UEFI compliant firmware.Comment: 6 page
Making online learning accessible to disabled students: an institutional case study
Based on the authors’ reflections on experience working at the Open University, approaches to making online learning accessible to disabled students are considered. The considerations are applicable to all concerned with online learning and indeed anyone seeking to trade, disseminate information and mediate services online. In reflecting on the Open University experience of making online material accessible, pedagogic, organisational and cultural issues are highlighted and it is argued that it is important to address these issues in order to effect the organisational change needed to ensure that accessibility challenges are effectively met

Digital inclusion - the vision, the challenges and the way forward
This paper considers the vision and aspiration of digital inclusion, and then examines the current reality. It looks beyond the rhetoric to provide an analysis of the status quo, a consideration of some facilitators and challenges to progress and some suggestions for moving forward with renewed energy and commitment. The far-reaching benefits of digital inclusion and the crucial role it plays in enabling full participation in our digital society are considered. At the heart of the vision of universal digital inclusion is the deceptively simple goal to ensure that everyone is able to access and experience the wide-ranging benefits and transformational opportunities and impacts it offers. The reality is a long way from the vision: inequality of access still exists despite many national campaigns and initiatives to reduce it. The benefits and beneficiaries of a digital society are not just the individual but all stakeholders in the wider society. Research evidence has shown that the critical success factors for successful digital participation are (i) appropriate design and (ii) readily available and on-going ICT (Information and Communication Technology) support in the community. Challenges and proven solutions are presented. The proposition of community hubs in local venues to provide user-centred ICT support and learning for older and disabled people is presented. While the challenges to achieve digital inclusion are very considerable, the knowledge of how to achieve it and the technologies which enable it already exist. Harnessing of political will is necessary to make digital inclusion a reality rather than a vision. With the cooperation and commitment of all stakeholders actualisation of the vision of a digitally inclusive society, while challenging, can be achieved and will yield opportunities and rewards that eclipse the cost of implementation
Understanding Cognition Across Modalities for the Assessment of Digital Resources
Drawing from the theories of the cognitive process, this paper explores the transmission, retention and transformation of information across oral, written, and digital modes of communication and how these concepts can be used to examine the assessment of digital resource tools. The exploration of interactions across modes of communication is used to gain an understanding of the interaction between the student, digital resource and teacher. Cognitive theory is considered as a basis for the assessment of digital resource tools. Lastly, principles for the assessment of digital resource tools are presented along with how assessment can be incorporated in the educational practice to enhance learning in higher education
The Evolution of E-Inclusion: Technology in Education for the Vision-Impaired
The 1970s and 1980s saw a rapid take-up in the use of personal computers. During the same time period, society began to move towards providing equity for people with disabilities. As legislators around the world created new disability and Information Technology policies, more people with disabilities were given access to education and the evolving computing tools provided unprecedented educational opportunities. These opportunities were due to the use of new technologies such as outputting of electronic text to voice synthesizers. The provision of assistive technology was not only helpful; it also provided education through a medium that was previously unavailable, particular to the blind and vision impaired. For much of the 1980s the development of text-processing sensory technologies, connected to personal computers, led to a closer equality between the educational services of the able-bodied and people with disabilities. Unfortunately this evolution as not without notable difficulties: issues surrounding the cost of products, the lack of support from large corporations and choice of platform resulted in substantial difficulties for educators in the assessment of appropriate technology. In addition, many of these products became largely redundant in the late-1980s as corporations began to place more emphasis on the Graphical User Interface (GUI). Although the GUI was remarkably successful in allowing the general public to gain better access to personal computing, it’s non-text nature once again caused a digital divide for people with disabilities. Although it is clear that the evolution of the personal computer has had a significant impact on the provision of education for people with disabilities, this paper highlights the historical repetition where innovation is prioritized above e-inclusion
Middle Level Education Aims for Equity and Inclusion, but Do Our School Websites Meet ADA Compliance?
An often-overlooked component of a middle school website is the necessity for that website to be accessible to those with disabilities, while following the guidelines of the Americans with Disabilities Act (ADA) and Section 508 of the Workforce Rehabilitation Act. In support of the belief that support the belief that inclusive education and respect for diversity should be integrated throughout the school, this study investigated the accessibility of middle school websites in Indiana, Kentucky, and Ohio by selecting a random sample of 150 schools and analyzing their homepages using WAVE (Web Accessibility Versatile Evaluator), which reports accessibility violations by annotating a copy of the page that was evaluated and presenting embedded icons and indicators to disclose breaches with ADA. Out of 150 districts, 54% had errors that need immediate attention and all 150 schools had alerts of likely violations that ranged from alt-text omissions and empty or confusing links to issues with color contrast and keyboard-only navigation. The article proceeds to give practical suggestions for eliminating many of the errors, even for those shareholders with less than sophisticated technological expertise
