    In this thesis accessibility problems with websites for vision-impaired persons are discussed in detail. General accessibility problems and those specific to e-commerce websites,especially on-line shopping websites are discussed. Accessibility problems are analyzed from the perspective of a screen reader user. As a solution for the accessibility problems identified, the WCAG 2.0 guidelines are reviewed and new changes are proposed to improve the existing guidelines. Enhanced solutions using tactile media capable of providing a better web browsing experience for vision-impaired persons are also discussed

    The principal sensory modality employed in learning is vision, and that not only increases the difficulty for vision impaired students from accessing existing educational media but also the new and mostly visiocentric learning materials being offered through on-line delivery mechanisms. Using as a reference Certified Cisco Network Associate (CCNA) and IT Essentials courses, a study has been made of tools that can access such on-line systems and transcribe the materials into a form suitable for vision impaired learning. Modalities employed included haptic, tactile, audio and descriptive text. How such a multi-modal approach can achieve equivalent success for the vision impaired is demonstrated. However, the study also shows the limits of the current understanding of human perception, especially with respect to comprehending two and three dimensional objects and spaces when there is no recourse to vision

    The VIVID model : accessible IT e-learning environments for the vision impaired

    Sighted learners and vision impaired learners experience different problems when accessing e-learning environments. Web designers use complex visual images and interactive features which learners with vision impairment are unable to access. Learners with vision impairment must rely on assistive technologies to acquire the information they are seeking. Vision impaired learners must have conversion facilities to translate the contents of these displays into readable and accessible formats.This research identifies problems faced by learners with vision impairment and demonstrates how e-learning environments must be modified to ensure success. The most significant problems are the lack of accessibility to teaching materials and an inability to participate in the learning experience to the same extent as sighted learners. Learning materials designed for sighted learners are often unsuited to those with vision impairment. Frequently, text provided is too small and unable to be altered; colour graphics are of little value unless accompanied by text or audio description and interactive Web sites present numerous challenges in navigation. Most courses are designed for sighted learners and learners with vision impairment struggle to maintain the required timeframe because of difficulties in reading texts and documents, completing assignments and sourcing reference materials due to their inaccessible formats and presentation.These problems result in lower academic achievement for vision impaired learners, which in turn lead to a lack of choices in employment opportunities. Learning environments for people with vision impairment need specific consideration in design and implementation. This ensures that the learning materials meet their needs and allow maximum accessibility so that the learners can achieve the same outcomes as their sighted peers.There is a small number of existing models to assist the design of e-learning sites for people with a disability. Kelley’s holistic model (2005) and Seale’s contextualised model (2006) are designed for people with disabilities in general and not specifically for those with vision impairment. Lazar’s Web accessibility integration model (2004) does not take into account the importance of social elements. Prougestaporn’s WAVIP model, (2010) whilst it has generic guidelines, the model is limited in its scope.Venable’s Design Science Research method was chosen to investigate the specific problems faced by vision impaired learners enrolled in IT e-learning courses. The characteristics of approximately one hundred adult vision impaired learners were investigated using two case study environments. The data were collected by observation and semi-structured interviews. Additionally, data were collected from these same learners to identify their specific needs in a Web-based learning situation. Accessibility needs were also identified and analysed. These activities involved the Problem Diagnosis stage in the Design Science Research model. Accessibility guidelines and legal and statutory requirements from several sources were also investigated. The components needed to deliver an effective, fully accessible IT curriculum in two Web-based e-learning environments for the vision impaired was then identified.Information was compiled from studying two learning environments for the vision impaired. Data instruments used in this phase were observations and semi-structured interviews with vision impaired learners and teachers. These activities involved the Problem Diagnosis and Theory Building stages of the Venable model. The relationships between the characteristics and needs of the learner, and the components of the learning environment for an Information and Communications and Technology (ICT) curriculum were analysed and then synthesised to build a conceptual model of an effective Web-based e-learning environment for the vision impaired.A new theoretical model, the Vision Impaired using Virtual IT Discovery (VIVID) was then developed. This holistic framework takes into account the specific needs of vision impaired learners. It also includes a social element which vision impaired learners identified as being extremely important to the success of their learning. This activity involved both the Technology Design/Invention state and the Theory Building stage in the Venable model.An evaluation was carried out by a focus group of eight experts in the field of accessible and e-learning course design and the model was then modified to incorporate their suggestions.The resulting model is a high level, comprehensive conceptual model that can be applied in differing pedagogical environments relating to IT education for adult learners with vision disabilities. It provides a framework to guide education managers, instructional designers and developers who are creating accessible IT e-learning environments for the vision impaired.Whilst this model relates only to the IT area, further research could extend its use to other curriculum areas and to those learners with multiple disabilities

    Access to books for the visually impaired: minimising charity and maximising choice

    This research aims to find ways of making access to copyrighted books for the visually impaired as much a matter of choice as possible by moving the provision of access away from models based on charity and of building the provision of access into the mainstream. The work of third sector organisations providing access and attempts by the visually impaired community itself to enhance access are described. Realities effecting support workers in universities who have to help visually impaired students investigated. Legal disputes relating to copyright and anti-discrimination law are discussed. Developments in the ebooks market are monitored with a particular reference to attempts to build accessibility into devices like the Kindle and Apple products. The research also looks at how best to secure access to online bookshops, web pages offering ebooks for download in public libraries and ebook libraries in academia. The current level of access being achieved in this area is assessed. Next ongoing attempts to improve access and differing views on the advisability of an approach based on enforcement of the Worldwide Web Consortium’s accessibility guidelines or a more flexible approach emphasising user testing are discussed. Conclusions and recommendations: changes to copyright law and further development and clarification of anti-discrimination law as it applies to publishers are necessary. Libraries should adopt a more innovative approach and field some of the specialist provision currently undertaken by charitable organisations. Accessibility to relevant websites is probably best provided by a combination of ongoing relationship building and with web developers and a more flexible approach than rigid enforcement of accessibility guidelines. Further research is needed on exactly how libraries could undertake specialist transcription most efficiently and on how to bring multi-national companies like Adobe, Amazon and other manufacturers of ebooks reading devices unambiguously into the ambit of anti-discrimination

    PT. Sinar Grafindo is a company engaged in the distribution of printing equipment that has clients throughout Indonesia. The problems that occur in PT. Sinar Grafindo is an employee data management that still has drawbacks, namely the recording of employee data is still using Microsoft Excel application. This causes no notification to Human Resource Development (HRD) when there are employees whose work contracts are almost up and there is no system for recording employee daily journals as a means of monitoring employees for leaders. Based on the conditions mentioned, this study aims to develop a based personnel information system web that is able to facilitate the management of employee data. System development is carried out using the Software Development Life Cycle (SDLC) method with a waterfall model. The programming language used is PHP 7.3 and uses the help of the CodeIgniter 3 framework. The Bootstrap framework 4 used to make it easier to make the system look more attractive. System development also uses the help of xampp version 3.2.4 as a local server. Based on the tests that have been carried out using the black box method shows that each function of the system can run well as needed. The results of this study are a web-based personnel information system that is able to manage employee personal data, leave requests, employment status, and employee daily journals in an integrated system

    Collaborative adaptive accessibility and human capabilities

    This thesis discusses the challenges and opportunities facing the field of accessibility, particularly as computing becomes ubiquitous. It is argued that a new approach is needed that centres around adaptations (specific, atomic changes) to user interfaces and content in order to improve their accessibility for a wider range of people than targeted by present Assistive Technologies (ATs). Further, the approach must take into consideration the capabilities of people at the human level and facilitate collaboration, in planned and ad-hoc environments. There are two main areas of focus: (1) helping people experiencing minor-to-moderate, transient and potentially-overlapping impairments, as may be brought about by the ageing process and (2) supporting collaboration between people by reasoning about the consequences, from different users perspectives, of the adaptations they may require. A theoretical basis for describing these problems and a reasoning process for the semi-automatic application of adaptations is developed. Impairments caused by the environment in which a device is being used are considered. Adaptations are drawn from other research and industry artefacts. Mechanical testing is carried out on key areas of the reasoning process, demonstrating fitness for purpose. Several fundamental techniques to extend the reasoning process in order to take temporal factors (such as fluctuating user and device capabilities) into account are broadly described. These are proposed to be feasible, though inherently bring compromises (which are defined) in interaction stability and the needs of different actors (user, device, target level of accessibility). This technical work forms the basis of the contribution of one work-package of the Sustaining ICT use to promote autonomy (Sus-IT) project, under the New Dynamics of Ageing (NDA) programme of research in the UK. Test designs for larger-scale assessment of the system with real-world participants are given. The wider Sus-IT project provides social motivations and informed design decisions for this work and is carrying out longitudinal acceptance testing of the processes developed here
