OATS - Open Source Assistive Technology - a way forward

The global Assistive Technology(AT)and Alternative and Augmentative Communication (AAC) software field, while expanding all the time, remains small land very specialised. AT is a relatively under funded field with its players widely spread across the globe. Open sourcing, if managed sensibly and creatively could offer the AT field an inexpensive opportunity to create, share, and above all disseminate good products that have high AT end user value but no (or relatively little)commercial interest or return. Open sourcing offers great potential for AT software users, however currently there are a number of barriers that stop its use in AT situations. It is generally difficult to find on the Internet and there are no specific areas dedicated to developing or downloading AT software. Open source software can also be unfriendly to install, often obliging the user to download many different packages before it can be used. This project is investigating the viability of the open source model for the future development of AT software. The OATS project removes these barriers to Open Source AT software: users will have a single point of contact for obtaining open source software and developers will have a forum to write software to meet the needs of specific users. The potential uses and market factors involved with Open Source AT software will be investigated and the underlying concepts promoted. Open Sourcing is a well-established and growing method of software development and it has potential to be beneficial within the Assistive Technology field. Open Source development allows multiple developers to work on software simultaneously even on different sides of the world it also encourages a very close relationship between the user and the developer. Many developers are looking to use their skills on interesting, challenging and worthwhile projects and offer a potential resource for the field that has not so far been utilised. Open Source also allows customisation to software œ an important aspect when working with such a diverse range of users as exist within the Assistive Technology community. Further to this, Open Source promotes common standards œ something very much lacking in existing Assistive Technology software œ and could allow better portability for users between programs. The main deliverable of this project is a website where users can find appropriate software to meet their needs and Open Source developers can find exciting and interesting projects. This software 'Repository' has a user-friendly web interface to allow users to browse the software and download/installitwith ease. The second part of the website, the 'Forge', allows software developers to find motivating, interesting and useful projects. The 'Forge' also provides a wide range of Open Source development tools including Subversion CVS (a tool to enable 'source code' to be stored on-line and for multiple developers to access it)and Trac(a project management tool and bug-tracking system). The site is developed using Plone - a powerful content management system that allows users control over their own project areas and provides a range of tools such as polls, noticeboards, FAQs etc. The website is fully accessible and meets the W3C WAI guidelines. To summarise the OATS project and website offers: - Downloadable Open Source AT software that is of sufficient quality to disseminate widely. - A 'forge' for the development of new Open Source AT software based on specific user needs. - A searchable list of links to other related websites - A discussion forum to promote discussion between end users, AT professionals and Open Source developers. And, in the longer term, itcouldalso provide: - Specific solutions to individual needs by 'tuning' existing applications - End users with help to develop solutions themselve

Exploring multiple factors affecting participation outcomes for children with communication aids

Many factors affect how much communication aids support and promote children’s participation in everyday settings. However, little research has explored which combinations of environmental, child and communication aid factors appear most influential. This paper will present preliminary findings from a pilot study of outcomes of communication aid provision to children. The main aims were to: (1) develop a self-report questionnaire for the parents and carers; (2) conduct a descriptive analysis of parents’ and carers’ perspectives. It is hoped that this presentation will stimulate discussion on issues such as identifying key influential factors in the take-up and use of communication aids and measuring children’s participation

An AAC enabled internet: from user requirements to guidelines

Ensuring that WWW pages are accessible and usable for people with complex communication needs provides a particular challenge for WWW page designers. Despite advances in commercially available assistive technologies, people using augmentative and alternative communication (AAC) comment on continuing difficulty and frustration in physical access to technology and subsequent reliance on non-disabled partners (Clarke et al., 2001 and 2002). The EU WWAAC (World Wide Augmentative and Alternative Communication) project, which began in January 2001, has been engaged in a number of research and development activities in order to overcome some of these problems, including the: • Development of Internet applications, including an adapted Web browser, tailored to the needs of people who use AAC • Contribution to the development of Web accessibility guidelines • Development of a communication infrastructure and protocol to support symbol-based communication on the Web, based upon open-sourced concept coding • Development of a Dreamweaver extension to enable Web developers to symbol embellish their Web pages via the on-line concept coding database. This paper will concentrate on the first 2 activities to demonstrate how the design, development and evaluation of an adapted Web browser with people who use AAC will lead to more accessible and usable software. This work is also contributing to the development of WWW accessibility guidelines, which will feed into the work of the World Wide Web Consortium–Web Accessibility Initiative (W3C–WAI). It is important, however, to consider these activities in light of the concept coding stream of the work, which is briefly described below. Concept coding will facilitate the sharing of symbol-based content between different symbol users using different symbol language systems. It will also enable symbols to be converted into text and vice versa. This might mean, for example, that a person who uses AAC could open an Internet bank account by completing an on-line form using their own symbol system. The vision of concept coding is that instead of images and symbols having to be transferred from one computer to another, it is possible to share a unique code designating the meaning of the symbol needing to be transferred. In addition to efficiency in handling images used for communication purposes, this concept would also allow personalised or idiosyncratic symbols specific to one person to be used by them in Internet-based communication. An open source concept coding, in combination with more accessible and usable software, is the driving force behind the WWAAC project

WWAAC Deliverable 13 - Final user interface report: the evaluation plan

This document provides an overview of the entire evaluation strategy for the project. Although a Workpackage 4 activity (User Interface: design and models for evaluation), this work has been accomplished in close collaboration, in fact virtual integration, with the activities and team members of Workpackage 1, User Involvement and Evaluation. It includes all of the detailed evaluation methods and tools, which were instrumental in developing the final user interface of the WWAAC software

WWAAC Deliverable 11 – Final User Evaluation Report

This document details the results from the user evaluation activities that have taken place with the WWAAC software since the User Requirements Capture (Deliverable 2). This includes evaluation of the: WWAAC Simulated Web Browser; WWAAC Web Browser (WWB); WWAAC Email (WEM); and WWAAC Supportive Writing (WSW). There have also been comparisons with alternative software on the market
