Virtual reality: Theoretical basis, practical applications

Virtual reality (VR) is a powerful multimedia visualization technique offering a range of mechanisms by which many new experiences can be made available. This paper deals with the basic nature of VR, the technologies needed to create it, and its potential, especially for helping disabled people. It also offers an overview of some examples of existing VR systems

Self-organization in Communicating Groups: the emergence of coordination, shared references and collective intelligence\ud

The present paper will sketch the basic ideas of the complexity paradigm, and then apply them to social systems, and in particular to groups of communicating individuals who together need to agree about how to tackle some problem or how to coordinate their actions. I will elaborate these concepts to provide an integrated foundation for a theory of self-organization, to be understood as a non-linear process of spontaneous coordination between actions. Such coordination will be shown to consist of the following components: alignment, division of labor, workflow and aggregation. I will then review some paradigmatic simulations and experiments that illustrate the alignment of references and communicative conventions between communicating agents. Finally, the paper will summarize the preliminary results of a series of experiments that I devised in order to observe the emergence of collective intelligence within a communicating group, and interpret these observations in terms of alignment, division of labor and workflow

A Support System for Graphics for Visually Impaired People

As the Internet plays an important role in today’s society, graphics is widely used to present, convey and communicate information in many different areas. Complex information is often easier to understand and analyze by graphics. Even though graphics plays an important role, accessibility support is very limited for web graphics. Web graphics accessibility is not only for people with disabilities, but also for people who want to get and use information in ways different from the ones originally intended. One of the problems regarding graphics for blind people is that we have few data on how a blind person draws or how he/she receives graphical information. Based on Katz’s pupils’ research, one concludes that blind people can draw in outline and that they have a good sense of three-dimensional shape and space. In this thesis, I propose and develop a system, which can serve as a tool to be used by researchers investigating these and related issues. Our support system is built to collect the drawings from visually impaired people by finger movement on Braille devices or touch devices, such as tablets. When the drawing data is collected, the system will automatically generate the graphical XML data, which are easily accessed by applications and web services. The graphical XML data are stored locally or remotely. Compared to other support systems, our system is the first automatic system to provide web services to collect and access such data. The system also has the capability to integrate into cloud computing so that people can use the system anywhere to collect and access the data

English/Arabic/English Machine Translation: A Historical Perspective

This paper examines the history and development of Machine Translation (MT) applications for the Arabic language in the context of the history and machine translation in general. It starts with a discussion of the beginnings of MT in the US and then, depending on the work of MT historians, surveys the decline of the work on MT and drying up of funding; then the revival with globalization, development of information technology and the rising needs for breaking the language barriers in the world; and last on the dramatic developments that came with the advances in computer technology. The paper also examined some of the major approaches for MT within a historical perspective. The case of Arabic is treated along the same lines focusing on the work that was done on Arabic by Western research institutes and Western profit motivated companies. Special attention is given to the work of the one Arab company, Sakr of Al-Alamiyya Group, which was established in 1982 and has seriously since then worked on developing software applications for Arabic under the umbrella of natural language processing for the Arabic language. Major available software applications for Arabic/English Arabic MT as well as MT related software were surveyed within a historical framework.Cet article examine l’histoire et l’évolution des applications de la traduction automatique (TA) en langue arabe, dans le contexte de l’histoire de la TA en général. Il commence par décrire les débuts de la TA aux États-Unis et son déclin dû à l’épuisement du financement ; ensuite, son renouveau suscité par la mondialisation, le développement des technologies de l’information et les besoins croissants de lever les barrières linguistiques. Finalement, il aborde les progrès vertigineux réalisés grâce à l’informatique. L’article étudie aussi les principales approches de la TA dans une perspective historique. Le cas de l’arabe est traité dans cette perspective, compte tenu des travaux effectués par les instituts de recherche occidentaux et quelques sociétés privées occidentales. Un accent particulier est mis sur les recherches de la société arabe Sakr, fondée dès 1982, qui a mis au point plusieurs logiciels de traitement de langues naturelles pour l’arabe. Ces divers logiciels de TA arabe-anglais-arabe ainsi que des applications associées sont présentés dans un cadre historique

Combating e-discrimination in the North West - final report

The Combating eDiscimination in the North West project examined over 100 websites advertising job opportunities both regionally and nationally, and found the vast majority to be largely inaccessible. Professional standards, such as using valid W3C code and adhering to the W3C Web Content Accessibility Guidelines, were largely not followed. The project also conducted interviews with both public and private sector web professionals, and focus groups of disabled computer users, to draw a broader picture of the accessibility of jobs websites. Interviews with leading web development companies in the Greater Manchester region, showed that there is a view there should not be any additional cost in making websites accessible, as the expertise to create a site professionally should be in place from the start, and that accessibility will follow from applying professional standards. However, through the process of trying to create a website for the project, with such a company, it was found that following professional standards is not sufficient to catch all the potential problems, and that user testing is an essential adjunct to professional practice. The main findings of the project are, thus, that: • Most websites in the job opportunities sector are not following professional standards of web development, and are largely inaccessible • Professional standards of web development need to be augmented with user testing to ensure proper accessibility
