The current presentation presents the approach followed for the derivation of the Use Cases developed in the context of ÆGIS Integrating Project (Grant Agreement: 224348) of the 7th Framework Programme, which constitute the core outputs of the user needs phase of the project, together with the Personas and the conceptual models, setting the basis for the upcoming development and evaluation phases of the project. ÆGIS aims to embed support for accessibility through the development of an Open Accessibility Framework (OAF), upon which, open source accessibility interfaces and applications for the users as well as accessibility toolkits for the developers will be built. Within ÆGIS, three mainstream markets are targeted, namely the desktop, rich Internet applications and mobile devices/applications market segments. The Use Cases developed address all three application areas, targeted by ÆGIS. The User Centred Design (UCD) plan defined from the early beginning of the initiative constituted the cornerstone of the work for the Use Cases, Personas and conceptual models. Following this plan, the project Use Cases have built on the outcomes of the field trials and the workshops (national and Pan-European), where a representative sample of all ÆGIS targeted user groups has participated and the valuable expertise of the ÆGIS Consortium members. Following a concrete development methodology, 36 Use Cases (12 for desktop, 15 for mobile and 9 for rich Internet applications), accompanied by Unified Modeling Language (UML) diagrams, 17 Personas covering all major target groups of the project and 13 conceptual models, which are mapped to the Use Cases, have emerged. The Use Cases will be further elaborated to specific application scenarios that will orient the evaluation to take place in ÆGIS in three iterative phases and across 4 Pilot sites (Belgium, Spain, Sweden and in the UK). The Use Cases are seen as working document, which may be subject to updates and revisions throughout the project, following and keeping up with the progress noticed in ÆGIS project and the overall open source accessibility community.

    • GIS FP7 project (Open Accessibility Everywhere: Groundwork, Infrastructure, Standards; http://www.aegis-project.eu)
      • S eeks to determine whether 3 rd generation access techniques will provide a more accessible, more exploitable and deeply embeddable approach in mainstream Information and Communication Technologies (ICT) .
      • This approach is developed and explored with the Open Accessibility Framework (OAF) through which aspects of the design, development and deployment of accessible mainstream ICT are addressed.
        • The OAF provides embedded and built-in accessibility solutions, as well as toolkits for developers, for engraving accessibility in existing and emerging mass-market ICT-based products, thus making accessibility open, plug & play, personalised & configurable, realistic & applicable in various contexts.
      • In this way, GIS is placing users and their needs at the centre of all ICT developments.

    • OAF is a comprehensive, holistic approach to programmatic support for assistive technologies.
    • This is in stark contrast to the 2 nd generation approach to accessibility via assistive technologies on the proprietary Windows platform.
    • Building on the pioneering 3 rd generation of the SoA Open Desktop in UNIX and GNU/Linux systems, OAF extends the concepts of programmatic accessibility in two directions:
      • upstream into the developer tools for creating accessible applications, and
      • downstream into further use and deployment into Internet technologies and mobile devices.
  • 4.
    • One of the key challenges addressed by GIS is to provide appropriate design solutions that will contribute to reducing the 30% of the European population currently not using ICT.
    • In order to address this issue effectively, GIS is committed to develop solutions that will receive wide acceptance from intended users.
    • For this purpose, the project has defined and is going to follow an appropriate user-centered development process , in which needs, wants, and limitations of the end user are given extensive attention at each stage of the development process.
    • The GIS approach requires designers to analyse and foresee how users are likely to use a design solution , as well as to test the validity of their assumptions with regards to user behaviour in real world tests with actual users.

    • Based on a holistic User Centred Approach (UCD), GIS identifies user needs and interaction models for several user groups (users with visual, hearing, motion, speech and cognitive impairments as well as application developers) and develops open source based generalised accessibility support into mainstream ICT devices/applications:
      • desktop,
      • rich web applications, and,
      • Java-based mobile devices.
  • 6.
    • Based on the findings of user needs and adopting a UCD approach, GIS had, first of all, to develop a series of Use Cases and basic application scenarios for the targeted application areas and user groups, in order to support all coming phases of the project (design, development and evaluation).
    • Subsequently, it had to map the Use Cases with Personas and feed conceptual models.

    • Graphic Symbol Support for facilitated text comprehension and production in OpenOffice.org.
    • Integration of open real-time into audio, video, and text-chat desktop applications.

    • All Use Cases are accompanied by UML diagrams.
    • Link to Personas (17 in total) has been established for each of them.
    • Priority level has been also established for each of them, namely: Essential, Secondary, Supportive.
      • Only 4 of them are considered supportive, whereas the rest of them are all considered essential for the project.
    • 3 major combination application scenarios are provided on the basis of the Use Cases envisaged.
    • Finally, based on the above, conceptual models have been produced.

    • Profile:
      • John, suffering from Usher syndrome, affecting both hearing and especially vision (retinitis pigmentosa).
      • Famous writer of travel guides for people with vision impairments.
      • So far, due to lack of accessible map websites and support, it has been difficult to organise his life independently (i.e. organising a trip on his own).
      • Now, GIS desktop, RIA and smartphone services make this much easier...
    • Scenario:
      • Through GIS enabled accessible internet maps, John is able to plan his trips ahead of schedule.
    • He is also able to explore new cities he visits. In that case:
      • He first finds walking directions from a selected point A (often his hotel) to point B (an accessible touristic site).
      • He accesses the map and direction application using the screen magnifier with an increased screen contrast, that also features speech synthesis (various languages are enabled allowing tours in a variety of foreign to him countries).
      • He detects any accessible interesting sites nearby his walking route and as soon as he selects, he uploads all needed information on his smartphone.
