The usability of software for authoring and editing

This research investigates some of the reasons for the reported difficulties experienced by writers when using editing software designed for structured documents. The overall objective was to determine if there are aspects of the software interfaces which militate against optimal document construction by writers who are not computer experts, and to suggest possible remedies. Studies were undertaken to explore the nature and extent of the difficulties, and to identify which components of the software interfaces are involved. A model of a revised user interface was tested, and some possible adaptations to the interface are proposed which may help overcome the difficulties. The methodology comprised: 1. identification and description of the nature of a ‘structured document’ and what distinguishes it from other types of document used on computers; 2. isolation of the requirements of users of such documents, and the construction a set of personas which describe them; 3. evaluation of other work on the interaction between humans and computers, specifically in software for creating and editing structured documents; 4. estimation of the levels of adoption of the available software for editing structured documents and the reactions of existing users to it, with specific reference to difficulties encountered in using it; 5. examination of the software and identification of any mismatches between the expectations of users and the facilities provided by the software; 6. assessment of any physical or psychological factors in the reported difficulties experienced, and to determine what (if any) changes to the software might affect these. The conclusions are that seven of the twelve modifications tested could contribute to an improvement in usability, effectiveness, and efficiency when writing structured text (new document selection; adding new sections and new lists; identifying key information typographically; the creation of cross-references and bibliographic references; and the inclusion of parts of other documents). The remaining five were seen as more applicable to editing existing material than authoring new text (adding new elements; splitting and joining elements [before and after]; and moving block text)

The design and evaluation of non-visual information systems for blind users

This research was motivated by the sudden increase of hypermedia information (such as that found on CD-ROMs and on the World Wide Web), which was not initially accessible to blind people, although offered significant advantages over traditional braille and audiotape information. Existing non-visual information systems for blind people had very different designs and functionality, but none of them provided what was required according to user requirements studies: an easy-to-use non-visual interface to hypermedia material with a range of input devices for blind students. Furthermore, there was no single suitable design and evaluation methodology which could be used for the development of non-visual information systems. The aims of this research were therefore: (1) to develop a generic, iterative design and evaluation methodology consisting of a number of techniques suitable for formative evaluation of non-visual interfaces; (2) to explore non-visual interaction possibilities for a multimodal hypermedia browser for blind students based on user requirements; and (3) to apply the evaluation methodology to non-visual information systems at different stages of their development. The methodology developed and recommended consists of a range of complementary design and evaluation techniques, and successfully allowed the systematic development of prototype non-visual interfaces for blind users by identifying usability problems and developing solutions. Three prototype interfaces are described: the design and evaluation of two versions of a hypermedia browser; and an evaluation of a digital talking book. Recommendations made from the evaluations for an effective non-visual interface include the provision of a consistent multimodal interface, non-speech sounds for information and feedback, a range of simple and consistent commands for reading, navigation, orientation and output control, and support features. This research will inform developers of similar systems for blind users, and in addition, the methodology and design ideas are considered sufficiently generic, but also sufficiently detailed, that the findings could be applied successfully to the development of non-visual interfaces of any type

Virtual Reality Games for Motor Rehabilitation

This paper presents a fuzzy logic based method to track user satisfaction without the need for devices to monitor users physiological conditions. User satisfaction is the key to any product’s acceptance; computer applications and video games provide a unique opportunity to provide a tailored environment for each user to better suit their needs. We have implemented a non-adaptive fuzzy logic model of emotion, based on the emotional component of the Fuzzy Logic Adaptive Model of Emotion (FLAME) proposed by El-Nasr, to estimate player emotion in UnrealTournament 2004. In this paper we describe the implementation of this system and present the results of one of several play tests. Our research contradicts the current literature that suggests physiological measurements are needed. We show that it is possible to use a software only method to estimate user emotion

Meeting the Standards in Primary ICT

This practical guide to using ICT in the primary classroom addresses all the concerns of student teachers and provides plenty of ideas and advice on how to incorporate ICT into classroom practice on a daily basis. The authors bring together theory and practice to help prospective and new teachers acquire and develop the skills required for using ICT effectively. Meeting the Standards in Primary ICT is split into three sections which will: help assess the readers' ICT skills, knowledge and understanding discuss ways of incorporating ICT for teaching across the primary curriculum help the reader to think about ICT and their own professional learning and development. This book will be an invaluable resource for all student teachers on primary training courses, lecturers and mentors supporting trainees on these courses and newly qualified teachers (NQTs)

The role of information technology in supporting the development of science linked technology education

This study builds on my earlier 1983 Masters research at Cranfield, which was an investigation of early technology education in the UK and USA and a pilot evaluation of the introduction of technology education into the curriculum of Stantonbury Campus in Milton Keynes, England. This gave an indication of the international trends in technology education and showed some of the potential of a problem-oriented approach to learning in schools based around a new integration of subjects and skills. It also showed the challenge to existing school teaching staff who often had to learn new skills themselves, often had to teach in new ways, and had to broaden their orientation after being single subject specialists most of their careers. Teaching materials had to be developed from scratch. IT had to be got to grips with. In September 1984, I took the post of Co-ordinator of the Schools Science and Technology Centre at the University of Oxford and had to implement a policy for sciencelinked technology education through a fast-changing period. During 1987 the pace of change accelerated rapidly being driven by the demands of the emerging new National Curriculum. By that time technology education, including IT, seemed to have become accepted as an important theme in the school curriculum in its own right. The Oxford Centre was there to offer in-service support in the development of training and teaching materials. It was, therefore, a good base for a study which could document the challenge of implementing technology education on a wide scale. In the end the sheer pace of change enacted by the government between 1987 and 1992, and shifts of position over the place of technology education, made the study a harder task than I expected. I was aiming at a fast moving target. But I hope the work is of value in exploring the link between the aspirations of those who advocate "technological capability and literacy" in our school population and what is currently being achieved. This thesis tries to explore the key areas of progress we need to make if technology education is to become a reality in our schools

The case study of SmarTerp

Synopsis: Technological advancement is reshaping the ways in which language interpreters operate. This poses existential challenges to the profession but also offers new opportunities. This books moves from the design of the computer-assisted interpreting tool SmarTerp as a case study of impact-driven interpreting technology research. It demonstrates how usability testing was used to achieve an interpreter-centred design. By contextualising the case study within the past and current developments of translation and interpreting technology research, this book seeks to inform and inspire a redefinition of the conceptualisation of interpreting technology research—not just as a tool to understand change but to drive it into a sustainable and human direction
