Design for Adaptive Content Processing

Design for Adaptive Content Processing: Introduction to the Special Thematic Session BIBAFull-Text 1-4
  David Crombie
The Special Thematic Session (STS) on Design for Adaptive Content Processing (ACP) is intended to provide a focus for different but related activities that can be described as having an emphasis on the design process rather than the end product of that process. The European Accessible Information Network (EUAIN) was established to bring together the different stakeholders in the accessible content processing chain and to build on common concerns. The parallel PRO-ACCESS project sought to build on this work and provide ISO 9001 industry-faced guidelines. The mainstreaming of adaptive content processing has also been given an added spur at a European level with the establishment of a high-level stakeholders group which is examining the needs of print impaired people and significantly increasing the current levels of provision.
Generating DAISY Books from OpenOffice.org BIBAKFull-Text 5-11
  Christophe Strobbe; Jan Engelen; Vincent Spiewak
odt2daisy is an open-source extension for OpenOffice.org Writer that converts word processing files into digital talking books in the DAISY format (ANSI/NISO Z39.86). odt2daisy produces Full DAISY 3 (text synchronised with audio), DAISY 3 XML (text without audio) and Full DAISY 2.02 (for compatibility with older DAISY players). The extension also supports mathematical content (MathML). odt2daisy works on Microsoft Windows, Mac OS X, Linux and Solaris. For the production of audio, odt2daisy relies on the DAISY Pipeline Lite, an open-source software developed by the DAISY Consortium, the LAME MP3 encoding technology, and the operating system's text-to-speech (TTS) engine(s). The supported languages depend on the TTS engines available on the user's system. On Unix-based systems odt2daisy relies on the open-source eSpeak TTS engine, which supports 27 languages. odt2daisy enables the production of DAISY books with only open-source software. Vincent Spiewak started working on odt2daisy at the Université Pierre et Marie Curie (Paris, France) and continued the work at the Katholieke Universiteit Leuven (Leuven, Belgium) in the framework of ÆGIS, a research and development project co-financed by the European Commission's 7th Framework Programme.

Combining Web Services and DAISY for the Production and Delivery of Audio Tactile Diagrams BIBAKFull-Text 12-19
  Declan McMullen; Donal Fitzpatrick
In recent years audio tactile diagrams have emerged as a viable method of providing blind learners with access to diagrammatical material. It has proven beneficial, but obstacles remain to its widespread adoption, especially in situations where a teacher may not be skilled in tactile production. Current approaches to audio tactile production contain limitations in various areas namely reusability, producer support and interoperability.
   This paper discusses the Audio Tactile Construction and Delivery Framework (ATCDF), which is a service based approach for the production and delivery of audio tactile diagrams. The approach separates audio tactile diagrams into their component parts, which are then stored independently of one another in repositories. The content in the repositories can be searched for, retrieved and reused independently of one another. Completed audio tactiles can be exported for delivery using the DAISY 3 standard, forming a DAISY based audio tactile. The approach has benefits in areas of reusability, interoperability and producer support.

Wiki, a New Way to Produce Accessible Documents BIBAFull-Text 20-26
  Alex Bernier; Dominique Burger; Bruno Marmol
Adapting complex documents to make them accessible for print disabled persons is an iterative process which involves various skills and requires the intervention of several people. Collaborative approaches are well suited, especially those based on Wikis which are now widely used to edit contents on the Web. A Wiki offers useful features to overcome some of the difficulties encountered when using word-processors. MediaWiki is a popular Wiki software which can be extended to allow users to import, edit and export contents using XML DTBook, the format designed by the DAISY Consortium for structuring text in an accessible way.
Guided Generation and Evaluation of Accessible Scalable Vector Graphics BIBAKFull-Text 27-34
  Bernhard Dürnegger; Christina Feilmayr; Wolfram Wöß
Web content, such as text, graphics, audio and video, should be available and accessible for everybody, but especially for disabled and elderly people. Graphics (like figures, diagrams, maps, charts and images), above all graphics with a high explanatory and content value, still may constitute massive barriers for specific user groups. Using Scalable Vector Graphics (SVG), an open standard published by the World Wide Web Consortium (W3C), provides new possibilities for the accessibility of web sites. SVG is based on XML and consequently gains important advantages like search and index functions. Moreover, SVG files can be processed by tactile displays or screen readers. To support the authoring process of graphics in order to make them accessible guidelines are developed, which empower the authors to detect and evaluate potential barriers in their own SVGs. An additional software-based evaluation tool conducts the authors in fulfilling the accessibility guidelines and simplifies the process of making SVG documents usable and valuable for as many people as possible.

Improving the Re-digitisation Process by Using Software with Automatic Metadata Detection BIBAKFull-Text 35-42
  Reinhard Ruemer; Klaus Miesenberger; Franz Kummer; Claus Gravenhorst
The provision of electronic documents for print-disabled persons is a key service of many institutions like libraries for the blind, educational facilities and other service providers for people with disabilities. Generally speaking all these institutions have defined a common internal workflow for providing these documents. A large amount of work falls on the task of restructuring the text and adding structural metadata for navigation. In this paper we describe the use of the commercial product docWORKS[e] by German company CCS and the challenges and benefits in terms of time and output quality we encountered by using this tool.

New Production and Delivery System for Pupils with Disabilities in Austria as Chance for Higher Quality Output BIBAKFull-Text 43-46
  Reinhard Ruemer; Klaus Miesenberger
The educational sector is a very diverse field when it comes to the type of content that is being used in the teaching of school pupils. To make these documents accessible and usable needs much more work than just to create a structured document that is readable and navigable for blind and visually impaired pupils. Often, exercise types especially in the first few grades at school very much rely on visual activities for example colour matching, naming of things etc. To make these types of exercises accessible additional work needs to be done. In the last years we have improved the production process of schoolbooks inasmuch as we were able to provide a solid basic accessibility now on which special education teachers can now work on the adaptation of specific exercise types like the above mentioned.

A Flexible Software Architecture Concept for the Creation of Accessible PDF Documents BIBAKFull-Text 47-52
  Alireza Darvishy; Hans-Peter Hutter; Alexander Horvath; Martin Dorigo
This paper presents a flexible software architecture concept that allows the automatic generation of fully accessible PDF documents originating from various authoring tools such as Adobe InDesign [1] or Microsoft Word [2]. The architecture can be extended to include any authoring tools capable of creating PDF documents. For each authoring tool, a software accessibility plug-in must be implemented which analyzes the logical structure of the document and creates an XML representation of it. This XML file is used in combination with an untagged non-accessible PDF to create an accessible PDF version of the document. The implemented accessibility plug-in prototype allows authors of documents to check for accessibility issues while creating their documents and add the additional semantic information needed to generate a fully accessible PDF document.

Exploiting the Daisy Format for Automated, Single-Source Braille Publishing BIBAKFull-Text 57-61
  Lars Ballieu Christensen
This paper presents the background and status of the projects and discusses opportunities and challenges of the AutoBraille/NorBraille approach of using Daisy talking books as the foundation for creating well-formatted, multi-volume Braille books ready for embossing. Whereas the current R&D projects are limited to relatively simple document structures, preliminary research suggests that it will be possible to automatically process even complicated math and science titles.

Rapid Listening of DAISY Digital Talking Books by Speech-Rate Conversion Technology for People with Visual Impairments BIBAKFull-Text 62-68
  Naoyuki Tazawa; Shinichi Totihara; Yukio Iwahana; Atsushi Imai; Nobumasa Seiyama; et al
We have performed studies and evaluation experiments of more acceptable rapid speech, aimed at implementation in applications such as installation in commercial devices designed for visually impaired persons. Although our method's playback time is same as the conventional High-speed playback technology, listener might feel playing in slower speeds and listen words clearer. Our proposal technology makes it possible to adaptive speech rate control in utterance position and pitch/power in the speech information, instead of changing the speed of the utterance uniformly. We performed an experiment in Japanese and American subject with visual impairments respectively to compare the conventional high-speed playback technology and that of our adaptive high-speed playback technology in terms of "Listenability". The reaction to our proposal method from subjects with visual impairments has been very positive underscoring its potential as an effective tool for listening to high-speed speech.

E-Books and Audiobooks: What about Their Accessibility? BIBAFull-Text 69-73
  Jan Engelen
Widespread distribution of electronic book readers, commonly called "e-readers" seems to have taken off seriously over the last year. Although the first e-readers popped up almost twenty years ago, last year's market appearance of a completely reworked Amazon Kindle 2, a new series of Sony PRS readers and several Bookeen & Cybook devices made e-books quite popular. All of them can store thousands of books, are extremely light weight and very mince. Many of them however present problems for persons with low vision or blindness. We will discuss briefly the situation and possible solutions.
E-Books and Inclusion: Dream Come True or Nightmare Unending? BIBAKFull-Text 74-77
  Alistair McNaught; Shirley Evans; Simon Ball
Nine e-book delivery platforms were tested for various aspects of accessibility. The results of this testing are discussed in terms of the roles and responsibilities in creating an accessible e-book delivery platform. The e-Book Access Bridge Model is introduced as a potential means of explaining to publishers the importance of ensuring every step in the process is barrier-free.

Collaboratively Generated Content on the Audio-Tactile Map BIBAKFull-Text 78-80
  Armin B. Wagner
The objective of the present study was to investigate the usage of audio-tactile maps in an educational context with visually impaired users, to pinpoint problem areas and to enhance or re-design a suitable system correspondingly. The gained insights led to the design of a modular e-learning tool, based on playful exploration, expression and participation. This is accomplished by harnessing recent advancements in collaborative content generation and geo-localized data available online.

Sonification of ASCII Circuit Diagrams BIBAKFull-Text 89-91
  Angela Constantinescu; Karin Müller
Graphics and diagrams can be made available to blind users mainly in two ways: via speech descriptions or tactile printing. However, both approaches require help from a sighted, well instructed third party. We propose here a fast and inexpensive alternative to making graphics accessible to blind people, using sound and a corpus of ASCII graphics. The goal is to outline the challenges in sonifying ASCII diagrams in such a way that the semantics of the graphics is successfully brought to their users. Additionally, the users should have the possibility to perform the sonifications themselves. The concept is exemplified using circuit diagrams.

Accessing Google Docs via Screen Reader BIBAKFull-Text 92-99
  Maria Claudia Buzzi; Marina Buzzi; Barbara Leporini; Giulio Mori; Victor M. R. Penichet
Groupware systems allow remote collaboration via computer in a simple, economic and efficient way. However, to be universally valuable, groupware systems must be accessible and usable for all, including the differently-abled. In this paper we discuss the results of testing the accessibility and usability of Google Docs (http://docs.google.com) when using a screen reader and a voice synthesizer, and suggest some basic guidelines for designing effective, efficient and satisfactory User Interfaces (UIs).

Making Digital Maps Accessible Using Vibrations BIBAKFull-Text 100-107
  Bernhard Schmitz; Thomas Ertl
In order to allow blind and deafblind people to use and explore electronically available maps, we have developed a system that displays maps in a tactile way using a standard rumble gamepad. The system is intended for both on-site and off-site use and therefore includes mechanisms for getting overviews of larger regions as well as for the exploration of small areas.

Non-visual Navigation of Spreadsheet Tables BIBAFull-Text 108-115
  Iyad Abu Doush; Enrico Pontelli
This paper presents a new system for non-visual navigation of tables located within a spreadsheet. The purpose is to provide a novel hierarchical non-visual navigation of tabular structures. The hierarchical view of the spreadsheet content, along with the user ability to select the desired table within a complex spreadsheet, provides greater flexibility than what offered by current assistive technologies. The proposed system allows the user to select a table and choose between different navigation strategies. The proposed approach introduces the solution in two stages: (i) table detection and recognition and (ii) non-visual navigation of the selected table. The system is provided as a plug-in for MS Excel™.
New Testing Method for the Dyslexic and the Newly Blind with a Digital Audio Player and Document Structure Diagrams BIBAKFull-Text 116-123
  Mamoru Fujiyoshi; Akio Fujiyoshi; Toshiaki Aomatsu
A new testing method with a digital audio player and document structure diagrams is developed for the dyslexic and the newly blind, who have difficulties with reading in braille or print. Since documents in the National Center Test for University Admissions are very long and have very complicated document structure, ordinary auditory testing media such as human reader or audio cassette are not appropriate. The new testing method can be administrated only with a digital audio player with 2-dimensional code reader and sheets of paper on which document structure diagrams and corresponding invisible 2-dimensional codes are printed.

Annotating and Describing Pictures -- Applications in E-Learning and Accessibility of Graphics BIBAKFull-Text 124-130
  Ivan Kopecek; Radek Ošlejšek
The paper describes the ontology based approach to the annotation of graphical objects in relation to the accessibility of graphics. Some applications in e-leaning are also discussed. The problem concerning the optimality of graphical ontologies in relation with the annotation process is addressed and an optimality measure enabling algorithmic solution of this problem is proposed. Finally, an approach to generating picture description is presented.

New Concepts of PC Interaction for Blind Users Based on Braille Displays with ATC Technology (Active Tactile Control) BIBAFull-Text 131-134
  Siegfried Kipke
Braille presented as a combination of raised dots is a very important way of accessing information for blind computer users offering crucial advantages compared to speech output. The ATC (Active Tactile Control) technology allows new PC interactions based on detecting the tactile reading position in real-time on a Braille display. Reading position sensitive assistant functions and context depended controls, like task overview and Braille frames, are introduced.

Inclusive E-Services for All: Identifying Accessibility Requirements for Upcoming Interaction Technologies BIBAKFull-Text 135-138
  Alejandro Rodriguez-Ascaso; Erik Zetterström; Martin Böcker; Helge Hüttenrauch; et al
Information and Communication Technologies (ICT) have the potential of facilitating the lives of citizens. However, experience consistently shows that user-interface innovations for consumer products are being researched and developed without taking into account the needs of people with disabilities. This situation is not helped by the fact that product and service developers can be unaware of the requirements of customers with impairments and therefore lack the insight into appropriate design solutions that may not be very demanding in terms of R&D and production costs. ETSI, the European Telecommunications Standards Institute, has established a Specialist Task Force (STF) 377 on "Inclusive eServices for all: Optimizing the accessibility and use of upcoming user interaction technology". The aim of this working group is to systematically evaluate ongoing and forthcoming interaction technologies to sketch a 10-year roadmap of foreseen technological enablers.

HAIL: Hierarchical Adaptive Interface Layout BIBAKFull-Text 139-146
  John Magee; Margrit Betke
We present a framework to adapt software to the needs of individuals with severe motion disabilities who use mouse substitution interfaces. Typically, users are required to adapt to the interfaces that they wish to use. We propose interfaces that change and adapt to the user and their individual abilities. The Hierarchical Adaptive Interface Layout (HAIL) model is a set of specifications for the design of user interface applications that adapt to the user. In HAIL applications, all of the interactive components take place on configurable toolbars along the edge of the screen. We show two HAIL-based applications: a general purpose web browser and a Twitter client.

Customizable Software Interface for Monitoring Applications BIBAKFull-Text 147-153
  Manuel Merino; Isabel Gómez; Octavio Rivera; Alberto J. Molina
In this paper we propose an application based on virtual keyboard and automatic scanning to communicate with a PC and the others people. The aim users are the people with disabilities. A high degree of customization is possible in the software. So the user can selected the color of buttons, position of system on screen, the kind of scanning, timer, the interface of communication, etc. Five people without disabilities tested our system. The results of the tests show the application reduce the fatigue of user and increased the text entry rate.

Towards to Real-Time System with Optimization Based Approach for EOG and Blinking Signals Separation for Human Computer Interaction BIBAKFull-Text 154-161
  Robert Krupinski; Przemyslaw Mazurek
Electrooculography (EOG) systems could be used for Human Computer Interaction but measurements with minimal number of electrodes and appropriate signals processing algorithms for the separation of EOG and blinking signals are required. Median filter with a carefully selected mask size could be used for the initialization of the evolution-based algorithm, which is used for the estimation and separation of EOG and blinking signals.

Towards Accessible Interactions with Pervasive Interfaces, Based on Human Capabilities BIBAFull-Text 162-169
  Matthew Tylee Atkinson; Yunqiu Li; Colin H. C. Machin; David Sloan
We draw on the literature, established standards and practices, contemporary funded projects and ongoing proof-of-concept work to argue for accessibility advocates to capitalise on the current paradigm shift towards ubiquitous, distributed and collaborative information systems. We discuss the contemporary interaction trends and accessibility challenges that give rise to our proposal; describe and provide an argument for capability-based development over the current, more device-focused, approach and document ongoing proof-of-concept and funded development work in this area.
Accelerometer & Spatial Audio Technology: Making Touch-Screen Mobile Devices Accessible BIBAKFull-Text 170-177
  Flaithri Neff; Tracey J. Mehigan; Ian Pitt
As mobile-phone design moves toward a touch-screen form factor, the visually disabled are faced with new accessibility challenges. The mainstream interaction model for touch-screen devices relies on the user having the ability to see spatially arranged visual icons, and to interface with these icons via a smooth glass screen. An inherent challenge for blind users with this type of interface is its lack of tactile feedback. In this paper we explore the concept of using a combination of spatial audio and accelerometer technology to enable blind users to effectively operate a touch-screen device. We discuss the challenges involved in representing icons using sound and we introduce a design framework that is helping us tease out some of these issues. We also outline a set of proposed user-studies that will test the effectiveness of our design using a Nokia N97. The results of these studies will be presented at ICCHP 2010.

An Open Source / Freeware Assistive Technology Software Inventory BIBAKFull-Text 178-185
  Alexandros Pino; Georgios Kouroupetroglou; Hernisa Kacorri; Anna Sarantidou; et al
Assistive Technology (AT) software market is expensive, and related products are hard to find, especially for non-English speaking users. Open Source and free AT software partially solve the cost problem, and online inventories facilitate the search for the appropriate product. Even so, users don't have all the information gathered and systematically organized in one place. Furthermore, free software often needs to be tested and reviewed by computer and AT experts in order to detect and point out reliability, installation, and compatibility issues. We propose a methodology for creating web-based free AT software inventories, which will make the search and selection of such products straightforward. The methodology is based on the systematic organization and consistency of the information available for each product, and its effective presentation; the goal for the users is to be able to quickly find, compare and understand the functionality and features of each product. We have applied this methodology to create the Open Source / Freeware AT software inventory http://access.uoa.gr/fs.

Designing and Developing Accessible Java Swing Applications BIBAFull-Text 186-188
  Theofanis Oikonomou; Konstantinos Votis; Dimitrios Tzovaras; Peter Korn
Existing development tools provide little out-of-the-box assistance in order to design and develop accessible ICT Java solutions for impaired users. Two new approximation simulation tools are presented in an attempt to achieve accessibility design and development of Java Swing applications.
Effects of Visual Stimuli on a Communication Assistive Method Using Sympathetic Skin Response BIBAKFull-Text 189-192
  Fumihiko Masuda; Chikamune Wada
We propose a communication assistive method that uses sympathetic skin response (SSR) as the input indicator for a device that will assist the disabled. To develop this method, we investigated the influence of optimal display conditions. SSR evokes visual stimuli. Therefore, we first clarified the optimal combination of background and character colors. The results show that the perception of conspicuousness increased as the contrast ratio increased. Then we investigated the change in the SSR appearance ratio in the conspicuous display condition; the result showed that the contrast had no influence on the SSR appearance ratio. In the future, we will conduct experiments on more subjects and further clarify the influence of visual stimuli.

Computerized Assessing the Mouse Proficiency through Multiple Indicators BIBAKFull-Text 193-199
  Ming-Chung Chen; Yun-Lung Lin; Chien-Chuan Ko
This study presents a computerized assessment tool which provides multiple parameters for evaluating a subject's pointing and selecting proficiency. The Mi-CAT system could provide effect parameters, quality parameters, and visual information that serve as the multiple indicators for clinical professionals to decide whether a pointing device or a setting is proper for a client. Besides introducing the Mi-CAT system, this study also explore the effectiveness of applying Mi-CAT in identifying a proper pointing device for a 7-year-old girl. The results reported that the multiple indicators generated from Mi-CAT system would pinpoint a better device or setting for this girl.

PUIR: Parallel User Interface Rendering BIBAFull-Text 200-207
  Kris Van Hees; Jan Engelen
While providing non-visual access to graphical user interfaces has been the topic of research for over 20 years, blind users still face many obstacles when using computer systems. The higher degree of flexibility for both developers and users poses additional challenges. Existing solutions are largely based on either graphical toolkit hooks, queries to the application and environment, scripting, or model-driven user interface development or runtime adaptation. Parallel user interface rendering (PUIR) is a novel approach based on past and current research into accessibility, promoting the use of abstract user interface descriptions. PUIR provides the mechanism to render a user interface simultaneously in multiple forms (e.g. visual and non-visual).
Transient Cooperation in Social Applications for Accessibility Mapping BIBAFull-Text 208-215
  Harald Holone; Jo Herstad
Collecting, disseminating and maintaining accessibility information about the physical world is a daunting task. Through the OurWay concept, end users are involved to provide feedback on suggested routes in a route planning system, thereby solving both their own navigational tasks at hand, and helping other users by leaving behind traces of their activity. We define and explore Transient Cooperation, the type of cooperation we have observed in a prototype evaluation of the concept. This exploration is undertaken in the light of established research on accessibility, cooperation and social software. We also suggest implications this type of cooperation can have for accessibility mapping.
A Social Approach to Accessible Social Networking Using the CAT Model BIBAKFull-Text 216-223
  Jennifer George; Gilbert Cockton; Thomas Greenough
The social model of disability looks beyond medical and technical solution moving towards social approach. This paper applies the label and table attributes of the CAT models to understand the social setting of the child with the disability together with the care circle. It goes on to understand their social needs and identifies accessibility challenges in communication between members of the care circle. Evaluation is carried out in both a computer and Internet based environment and a traditional communication environment. Finally brief guidelines are drawn upon which an accessible social network based design solution could be built for the reduction of disability of children with motor impairment.

Entertainment Software Accessibility

Entertainment Software Accessibility: Introduction to the Special Thematic Session BIBAFull-Text 224-226
  Dominique Archambault
This year will see the fifth edition of this Special Thematic Session. In ten years we have seen the growing awareness of game accessibility in our community of people who aim at helping other people with digital devices, and in the same time in the community of games designers. But this is not enough. Indeed in the real market there is about no accessible game in the blockbusters. For readers interested in this topic, more information can be found in [3], an extensive State of-the-Art paper about Computer Games and Visually Impaired People.
User Interface Evaluation of Serious Games for Students with Intellectual Disability BIBAKFull-Text 227-234
  Cecilia Sik Lanyi; David J. Brown; Penny Standen; Jacqueline Lewis; Vilma Butkute
We have designed and evaluated around 10 serious games under the EU Leonardo Transfer of Innovation Project: Game On Extra Time (GOET) project http://goet-project.eu/. The project supports people with learning disabilities and additional sensory impairments in getting and keeping a job by helping them to learn, via games-based learning; skills that will help them in their working day. These games help students to learn how to prepare themselves for work, dealing with everyday situations at work, including money management, travelling independently etc. This paper is concerned with the potential of serious games as effective and engaging learning resources for people with intellectual disabilities. In this paper we will address questions related to the design and evaluation of such games, and our design solutions to suit the individual learning needs of our target audiences.

Making Mainstreaming Videogames More Accessible: A Pilot Study Applied to Buzz!™ Junior Monster Rumble for PlayStation BIBAKFull-Text 235-242
  Elena Laudanna; Maria Bulgheroni; Francesca Caprino; Serenella Besio
In this article the authors analyse the critical factors concerning accessibility of the videogame Buzz!™ Junior Monster Rumble for the Playstation console. The objective of the study is to propose a series of modifications that, on the one hand, do not change the graphic and playability features of the game and, on the other, expand the target of users to include children with cognitive and/or motor disabilities. If this method turns out to be feasible and applicable it could also be extended to more complex games in terms of functions and required skills, contributing to a more inclusive approach within the research and study of videogame accessibility. The reasons for choosing this particular game are an essential precondition for a comprehensive study.

Using Placement and Name for Speaker Identification in Captioning BIBAKFull-Text 247-254
  Quoc V. Vy; Deborah I. Fels
The current method for speaker identification in closed captioning on television is ineffective and difficult in situations with multiple speakers, off-screen speakers, or narration. An enhanced captioning system that uses graphical elements (e.g., avatar and colour), speaker names and caption placement techniques for speaker identification was developed. A comparison between this system and conventional closed captions was carried out deaf and hard-of-hearing participants. Results indicate that viewers are distracted when the caption follows the character on-screen regardless of whether this should assist in identifying who is speaking. Using the speaker's name for speaker identification is useful for viewers who are hard of hearing but not for deaf viewers. There was no significant difference in understanding, distraction, or preference for the avatar with the coloured border component.

User Feed-Back in the Development of an Information System for Public Transport BIBAKFull-Text 273-279
  Christian Bühler; Helmut Heck; Christian Radek; Rainer Wallbruch; Josef Becker; et al
Within the German projects BAIM and BAIM plus, information services for people with reduced mobility have been developed. These accessible and adaptable services provide information on public transport. The challenge was to provide sufficient information so that accessible, barrier free journeys can be planned in advance and undertaken in real life. These services are available on the internet and on telephones (mobile phones) prior to and while travelling. User evaluation of these developed and implemented services lead to notable suggestions for further development activities.

User-Specific Web-Based Route Planning BIBAFull-Text 280-287
  Bettina Pressl; Christoph Mader; Manfred Wieser
A web-application for route planning should allow users with special requirements like blind or visually impaired people, and wheelchair users to increase their mobility in urban areas. Especially when visiting an unknown city as a tourist, detailed information is needed. Based on a developed digital map for these special user groups, route planning of barrier-free routes with additional information and pre-trip training will be provided. Moreover, public transport is essential for these user groups. Individual user profiles enable the definition of preferences for every single user which will influence route planning and visualization. The upcoming challenges in data modeling and route planning by using time schedules of public transport and multi-criteria optimization are discussed in this article.

Challenges for Norwegian PC-Users with Parkinson's Disease -- A Survey BIBAKFull-Text 292-299
  Miriam Eileen Nes Begnum
This paper presents the results from a Norwegian survey on the computer use of people with Parkinson's disease (PD), conducted through the PIKT project in the summer of 2008. The study shows that nearly 80% of the user population has significant and severe PD related challenges using a computer. Frequent problem areas include inertia, muscle stiffness, using a computer mouse, tremor and issues related to keyboard and ergonomics. Assistance in optimizing computer use is severely lacking, non-systematic and coincidental, and the employment rate among the respondents is about half of the national average. This paper describes the main findings from this study. It highlights main challenges for the user group in question, confirms national findings on gender, computer illiteracy and usage aspects, paints a picture of the current situation for PC-users with Parkinson's disease in Norway and discusses the implications of the findings.

Usability and Usefulness of GPS Based Localization Technology Used in Dementia Care BIBAKFull-Text 300-307
  Øystein Dale
Dementia is a chronic brain disease affecting cognitive functioning. People with dementia have a higher risk of getting lost. In recent years GPS based technology has been utilised to locate lost persons with dementia. We interviewed six families using such technology focusing on perceived usability, user-friendliness and usefulness. The informants also completed the QUEST 2.0 questionnaire which measures satisfaction with assistive technology. By and large the informants found the equipment easy to use, and it was viewed by all as being very useful. There were a number of usability issues which adversely affected usage, e.g. system stability, secure fastening, size, user interface issues and varying GPS-reception. The QUEST 2.0 results corresponded with the findings in the interviews. Further usability studies, as well as R&D to address issues such as security and privacy protection and use in the public health sector are needed.

Usable Web Accessibility: Editing

Merging Web Accessibility and Usability by Patterns BIBAFull-Text 336-342
  Helmut Vieritz; Daniel Schilberg; Sabina Jeschke
Nowadays, usability and accessibility are two important quality aspects of user interfaces (UIs). But in research and development, both are sometimes accounted as unity and sometimes as contradiction. Understanding Web accessibility as an essential part of usability, here an approach is given to clarify the relationship of both. Therefore,
  • a pattern approach was chosen to meet the practical requirements of UI
       designers which are often not familiar with accessibility needs,
  • a collection of patterns for human-computer interaction (HCI) has been
       extended with accessibility requirements and
  • finally a pattern example illustrates the cooperation of usability and
       accessibility in detail.
  • Towards the Convergence of Web 2.0 and Semantic Web for E-Inclusion BIBAKFull-Text 343-350
      Laura Burzagli; Andrea Como; Francesco Gabbanini
    The paper discusses a research approach to achieve the "wider inclusion objectives" reported in the second part of the Riga declaration. The approach is based on the convergence of two forms of intelligence on the web, given by Web 2.0 and the Semantic Web. While Web 2.0 encompasses social phenomena, often undervalued in the field of e-Inclusion (exchange and collection of large amount of information), Semantic Web is designed for interlinking and reusing structured information. The paper outlines a software architecture for the exploitation of the above concepts and gives an example of a possible application built on top of the architecture, in the domain of inclusive e-Tourism, enlightening benefits that come by the adoption of the approach, with respect to current trip planning systems.

    Beyond a Visuocentric Way of a Visual Web Search Clustering Engine: The Sonification of WhatsOnWeb BIBAKFull-Text 351-357
      Maria Laura Mele; Stefano Federici; Simone Borsci; Giuseppe Liotta
    It is widely accepted that spatial representation is processed by an amodal system. Recent studies show that blind subjects have a better motion ability than sighted people in performing spatial exploration guided only by auditory cues. The sonification method offers an effective tool able to transmit graphic information, overcoming the digital divide risen by a visuocentric modality in which contents are conveyed. We present a usability evaluation aiming at investigate the interaction differences between both blind and sighted users while surfing WhatsOnWeb, a search engine that displays the information by using graph-drawing methods on semantically clustered data. We compare the visual presentation of three different layouts with the sonificated ones, demonstrating both qualitatively and quantitatively that blind and sighted users perform with no significant differences the interaction. These results remark that the digital divide could be decreased by going beyond the visuocentric way of the commonly adopted visual content representation.

    We can access to large amounts of information on the web. Searching and getting information has become much more important. Using assistive products, visually impaired people also can access to a goodly portion of them, but getting information they need still takes long time. We introduce our software "Finger Skitter", which is being developed not for reading a document but for getting information with voice navigation. This software provides 2 types of user interface to rapidly get "what the document is written about" and "where is the information in the document". We implement a prototype of the software with JavaScript, which uses live-regions supported in WAI-ARIA to control a speech engine.
    The Evaluations of Deletion-Based Method and Mixing-Based Method for Audio CAPTCHAs BIBAKFull-Text 368-375
      Takuya Nishimoto; Takayuki Watanabe
    Audio CAPTCHA systems, which distinguish between software agents and human beings, are especially important for persons with visual disability. The popular approach is based on mixing-based methods (MBM), which use the mixed sounds of target speech and noises. We have proposed a deletion-based method (DBM) which uses the phonemic restoration effects. Our approach can control the difficulty of tasks simply by the masking ratio.
       According to our design principle of CAPTCHA, the tasks should be designed so that the large difference of performance between the machines and human beings can be provided. In this paper, we show the experimental results that support the hypotheses as follows: (1) only using MBM, the degree of task difficulty can not be controlled easily, (2) using DBM, the degree of task difficulty and safeness of CAPTCHA system can be controlled easily.

    The purpose of this project is to investigate ways of leveraging the collaborative and multi-user nature of modern Learning Management Systems (LMSs) to enhance accessibility of online courses for individuals with visual disabilities. The underlying principle of the project is the generation of semantics annotation for all components of an online course -- that can be used to guide assistive devices. The semantic information can be added in a three different forms (a predefined ontology class, user tags, and annotations). This semantic information is used by assistive technologies (e.g., screen readers) to help visually impaired students when they acquire knowledge from the on-line course materials.

    Using Collaborative Learning to Teach WCAG 2.0 BIBAFull-Text 400-403
      Fernando Alonso; José L. Fuertes; Ángel L. González; Loïc Martínez
    Version 2.0 of the Web Content Accessibility Guidelines (WCAG) was published in December 2008. WCAG 2.0 has a different language, a different structure and a different rationale to WCAG 1.0. All of these influence how to teach web accessibility. In this paper we present an innovative approach that we have followed in a web accessibility module that is taught at the UPM's School of Computing as part of the BEng degree in Computer Science. Our approach combined several teaching methods: traditional lectures, collaborative learning sessions, a short exercise on web site evaluation and, finally, a short project consisting of the development of an accessible web site. In the paper we describe the methods used and the results.

    Assessing WCAG 2.0 Conformance in Practice BIBAKFull-Text 408-412
      Sylvie Duchateau; Denis Boulay; Dominique Burger
    On December 11, 2008, the W3C published the Web Content Accessibility Guidelines 2.0 as the new W3C recommendation. WCAG 2.0 aims to be more flexible and does not rely on a specific technology. Moreover W3C/WAI claims that WCAG 2.0 has been designed to be testable as to respond to multiple demands from stakeholders. However, few implementations have been completed yet providing enough feedback about WCAG 2.0 conformance systems over a long period. This paper will discuss the need for a methodology to ensure conformance to WCAG 2.0 that takes the new constraints of this standard into account. It will propose a process for developing this assessment methodology according to specific requirements. It identifies several steps that proved to be essential towards operational results. Finally, it discusses the possible benefits of such a methodology.

    Is the Accessibility Audit Dead? BIBAKFull-Text 413-416
      Joshue O. Connor
    The Accessibility Audit has long been a staple of the usability professional and web accessibility specialists' toolkit. An audit is where problematic issues that limit the accessibility of a web site or application can be highlighted in a granular fashion, solutions outlined and statements of conformance to accessibility guidelines, like WCAG, teased out. However, in practice is the accessibility audit really the right tool for the job? As a methodology does it efficiently help to advance the cause of improving the accessibility of web sites and applications? Or effectively raise awareness of inclusive design amongst developers? Or is it merely an inert rubber-stamping exercise that could be replaced or enhanced by more progressive methods? [1]

    Evaluating Conformance to WCAG 2.0: Open Challenges BIBAKFull-Text 417-424
      Fernando Alonso; José L. Fuertes; Ángel L. González; Loïc Martínez
    Web accessibility for people with disabilities is a highly visible area of work in the field of ICT accessibility, including many policy activities in several countries. The commonly accepted guidelines for web accessibility (WCAG 1.0) were published in 1999 and have been extensively used by designers, evaluators and legislators. A new version of these guidelines (WCAG 2.0) was published in 2008. In this paper we point out the main challenges that WCAG 2.0 raises for web accessibility evaluators: the concept of "accessibility supported technologies"; success criteria testability; technique and failure openness, and the aggregation of partial results. We conclude the paper with some recommendations for the future.

    Automatic Checking of Alternative Texts on Web Pages BIBAFull-Text 425-432
      Morten Goodwin Olsen; Mikael Snaprud; Annika Nietzio
    For people who cannot see non-textual web content, such as images, maps or audio files, the alternative texts are crucial to understand and use the content. Alternate texts are often automatically generated by web publishing software or not properly provided by the author of the content. Such texts may impose web accessibility barriers. Automatic accessibility checkers in use today can only detect the presence of alternative texts, but not determine if the text is describing the corresponding content in any useful way. This paper presents a pattern recognition approach for automatic detection of alternative texts that may impose a barrier, reaching an accuracy of more then 90%.
    OASES: Online Accessibility Self Evaluation Service -- A Web-Based Tool for Education Institutions to Self-Assess the Accessibility of Their Practice BIBAKFull-Text 433-436
      Simon Ball; Alistair McNaught; Sue Watson; Andrew Chandler
    The JISC TechDis service identified a need to move institutions forward in their accessibility 'maturity'. An 'Accessibility Maturity Model' was developed to highlight the stages of development that different institutions were exhibiting. In order to move institutions forward an Online Accessibility Self Evaluation Service (OASES) was created. OASES allows key managers in education institutions to evaluate their own practice, and to benchmark that practice against the anonymised results of their peers. This information can then be used to affect institutional policy and strategy to move their institution to a higher degree of 'accessibility maturity'.

    User Testing of Google Reader and RIA Complexity -- A Warning BIBAKFull-Text 444-448
      Joshue O. Connor
    There are many APIs and toolkits available in the wild today that allow developers to build rich sophisticated Web Applications. There are a variety of frameworks and toolkits at use in the wild. While these platforms -- in principle -- offer the promise of greater functionality and more robust interoperability they also cast a potential shadow of greater complexity and how will this complexity then impact on the user experience for people with disabilities? In tandem, there are many guidelines designed to help make inclusive, accessible and usable designs a reality such as the principles of Universal Design, the WCAG and other international usability standards. [1][2][3].
       So how can we ensure that when we build complex Rich Internet Applications (RIAs) that they can be easily used by the widest possible audience, including older people and people with disabilities? A well-established method is to conduct a user test.

      Annika Nietzio; Morten Goodwin Olsen; Mandana Eibegger; Mikael Snaprud
    Accessibility benchmarking is efficient to raise awareness and initiate competition. However, traditional benchmarking is of little avail when it comes to removing barriers from eGovernment web sites in practice. Regulations and legal enforcement may be helpful in a long-term perspective. For more rapid progress both vendors and web site maintainers are willing to take short-term action towards improvements, provided that clear advise is available. The approach of the eGovernment Monitoring project (eGovMon) integrates benchmarking as a central activity in a user-driven project. In addition to benchmarking results, several other services and background information are provided to enable the users -- in this case a group of Norwegian municipalities who want to improve the accessibility of their web sites -- to gain real added value from benchmarking.

      Helen Petrie; Christopher Power; Carlos A. Velasco; Jesus G. Boticario
    Blended learning, the use of a combination of face-to-face and distance learning techniques, is becoming very common in all educational sectors. Almost all educational institutions now use websites to communicate with students, provide them with learning resources and, increasingly, allow students and staff to collaborate with each other. Many institutions use their own websites, others use virtual learning environments (VLEs) or learning management systems (LMSs). The transition of institutions to all learning being through electronic channels, or e-learning, is also becoming increasingly prevalent, particularly in the higher and further education domains. Even in primary and secondary school systems, the integration of virtual classrooms, multimedia resources and electronic whiteboards have further blurred the lines between the virtual and the physical world.

    This study investigated the knowledge of educational professionals on the needs and preferences of disabled and mature age students in further and higher education. 102 Interviews and 6 focus groups were conducted in 4 European countries (Austria, Italy, Spain, and the UK) as well as in New Zealand and the USA. An online survey was publicised worldwide and 343 educational professionals from 21 countries responded. The results indicated a lack of standardisation in training and gaps in the knowledge and attitudes of educational professionals regarding how to appropriately support disabled and mature age in higher and further education. The use of e-learning technologies to address these issues is highlighted, as well as what is needed in future to better support not only disabled and mature age students but also the educational professionals who support them.

    Design Guidelines for Developing Curriculum-Focused ICT Materials for Diverse Students BIBAKFull-Text 495-502
      Cara Nicole Greene
    This paper presents design guidelines for developing curriculum focused Information Communication Technology (ICT) materials for diverse students with special needs in the inclusive secondary school setting. Mainstream and learning support teachers and students who developed these guidelines first took part in 'use of ICT' questionnaires and took part in a three-month study investigating how these ICTs impacted on their classroom teaching. The teachers and students involved then took part in evaluation questionnaires and focus groups to develop design guidelines and good practice for developing curriculum-focused ICTs for diverse students. The guidelines were used to develop curriculum-focused materials for aspects of the Irish Junior Certificate (JC) English and History curricula [2]. English and History teachers and learning support teachers used the materials for three months with their classes and carried out an evaluation. Results showed that while mainstream teachers and students found the materials useful for enhancing the curriculum, the real benefit was for the learning support teachers and students.

    A Framework to Support Development of Learning Applications for Disabled Children BIBAKFull-Text 503-510
      José L. Fuertes; Ángel L. González; Gonzalo Mariscal; Carlos Ruiz
    Multimedia resources are an important tool that can be used by teachers in the classroom as a learning aid for learners with disabilities or by parents and children at home. However, disabled children are not always able to use existing assistive technologies because they are not experienced enough, suffer from medium/profound disability, or simply do not have the financial resources to buy commercial tools. Additionally, today's adapted tools are not always valid for a broad spectrum of disabled users and often focus on a user group. We claim that potential applications and resources for people with special needs must self-adapt to user capabilities and skills, reducing the use of external assistive technologies. In this paper, we present a guide for developers to create accessible applications and resources that reduce workload.

    Successful Service Provision

    ICT for Persons with Disabilities: Bridging the Digital Divide in Bangladesh BIBAKFull-Text 527-530
      Mahjabeen Khaled Hossain
    In the last two decades, the disability situation has undergone substantial change globally due to international initiatives supporting the UN declared World Decade of Disabled Persons. However, these progressive steps are yet to reach millions of disabled persons in rural Bangladesh. Around 13 million people in Bangladesh are physically handicapped of which 3 million are children. Disability is increasing with population growth and ageing. Disability on this scale represents not only a major health issue but also a prime cause of poverty and underdevelopment. Information and Communication Technology (ICT), opens up great opportunities to improve the quality of life of disabled people failing which will further the digital divide. This paper proposes to discuss the importance of ICT development and accessibility for persons with disabilities in Bangladesh and elaborate on how ICT has been utilized thus far and how we can further these initiatives towards development.

    Easy-to-Use Social Network Service BIBAKFull-Text 544-549
      Niina Sillanpää; Sami Älli; Timo Övermark
    Social media have become important tools for social networking. However, most services are too complicated for people with learning disabilities or cognitive impairments. The problems are mostly related to understanding the different concepts of the environment and related special terminology, but accessibility and usability problems common to all internet services also apply. To tackle these problems, a project was started, aiming to create an easy-to-use social network service for the above mentioned target group by applying user-centered design methods. This paper explains the rationale for starting the project and also describes the some of the implementation methods used.

    Standards: A Driver for Accessibility and Usability

    Standards Are Drivers for Accessibility and Usability: Introduction to the Special Thematic Session BIBAFull-Text 550-552
      Jan Engelen; Christian Bühler
    Standardisation of products and services developed with a Design for All or Universal Design perspective in mind has been a recurrent theme at the ICCHP conferences. Since the 2008 edition a special thematic session has been organised, bringing together the different contributions in this field. We will describe briefly the 2010 STS. Furthermore as this year's theme of the World Standards Day (organised by ISO, ITU and IEC) will be "Accessibility", some background information on this important issue will be given.
    International AT and DfA Standardisation: What Is in the Pipeline? BIBAFull-Text 553-560
      Jan Engelen
    In this contribution several recent actions in the field of Standardisation related to Assistive Technology and Design for All are reported. The main focus will be on several CEN initiatives, the status of Mandate 376 and the current EU Commission's plans for issuing a new mandate on the inclusion of "Design for All" in relevant standardisation initiatives.
    Redefining Assumptions: Accessibility and Its Stakeholders BIBAKFull-Text 561-568
      Rui Lopes; Karel Van Isacker; Luís Carriço
    Accessibility is becoming more and more relevant in Information technologies, such as the Web and software applications, particularly due to the push on legislation to make public services accessible to everyone. While most accessibility issues are envisioned by the developer-user dichotomy, several stakeholders are responsible for the successful implementation of accessible software and services for all users.
       In this paper we present an exploratory study on the current state of accessibility as perceived by its main stakeholders: developers, service providers, public bodies, accessibility assessors, and elderly and people with disabilities. By surveying more than 400 individuals, we have confirmed some of the expectations and results from other surveys, such as the perception about the lack of understanding and application of Web accessibility guidelines. We have found that this issue gets even worse outside the scope of the Web, for all stakeholders. Another eye-opening finding is that all stakeholders are welcome to the simulation of assistive technologies, in order to widen the perception and involvement of accessibility in the software development process.

    Stand4All: Promoting More Accessible Standards through Training of Stakeholders BIBAFull-Text 569-572
      Christophe Strobbe; Charlotte Mosies; Christian Bühler; Jan Engelen
    The Stand4All project is a response to a call for tenders by the European Commission's Directorate-General for Employment, Social Affairs and Equal Opportunities. Its goal is to increase the use of CEN/CENELEC Guide 6, which contains guidance on the inclusion of the needs of elderly persons and persons with disabilities during the standards development process. To reach this goal, the project consortium has developed and delivered training on standardisation in several locations in Europe and for two types of audience: persons with disabilities and members of standardisation committees. The training for persons with disabilities is meant to increase their effective participation in the standardisation process. The training for committee members is meant to increase their awareness and knowledge of accessibility issues faced by persons with disabilities.
    Standards-Based Content Resources: A Prerequisite for Content Integration and Content Interoperability BIBAKFull-Text 573-579
      Christian Galinski; Karel Van Isacker
    Standardized content repositories (and content repositories based on international standards) for structured content are becoming increasingly important for ICT-assisted communication among users, between users and their devices, and among these devices. Given the increasing ubiquity and pervasiveness of ICTs -- especially in the communication with and around people with disabilities -- it should be assured that ICTs are accessible and inclusive and that they and the standards-compliant data models used facilitate content interoperability. If not, remedial or additional programming may become necessary, which tend to be very costly or even impossible at times. Content interoperability (of structured content) as defined in this article also means -- especially if the content itself is collectively developed and maintained on the basis of international standards -- that effective methods and efficient tools can be conceived for verification, validation and certification.

    People with Speech Impairment: "Weak and Silent Speech": Tools to Support People with Speech Impairment

    ICCHP Keynote: Recognizing Silent and Weak Speech Based on Electromyography BIBAFull-Text 595-604
      Tanja Schultz
    In the past decade, the performance of automatic speech processing systems, including speech recognition, spoken language translation, and speech synthesis, has improved dramatically. This has resulted in an increasingly widespread use of speech and language technologies in a large variety of applications. However, speech-driven interfaces based on conventional acoustic speech signals still suffer from several limitations.
    CanSpeak: A Customizable Speech Interface for People with Dysarthric Speech BIBAKFull-Text 605-612
      Foad Hamidi; Melanie Baljko; Nigel Livingston; Leo Spalteholz
    Current Automatic Speech Recognition (ASR) systems designed to recognize dysarthric speech require an investment in training that involves considerable effort and must be repeated if speech patterns change. We present CanSpeak, a customizable speech recognition interface that does not require automatic training and uses a list of keywords customized for each user. We conducted a preliminary user study with four subjects with dysarthric speech. Customizing the keyword lists doubled the accuracy rate of the system for two of the subjects whose parents and caregivers participated in the customizing task. For the other two subjects only small improvements were observed.

    Adding Voice to Whisper Using a Simple Heuristic Algorithm Inferred from Empirical Observation BIBAKFull-Text 613-620
      Rüdiger Heimgärtner
    The aim of the work described in this paper is to allow people that are enforced to use "whispery voice" to be endowed with "voiced voice". A very simple method and algorithm obtained by empirical observation of corresponding speech signals is presented and discussed. Only well-known methods like FFT, interpolation, normalization, and formant shifting are used. It turned out that the quality of the processed speech signal is adequate to be understood by hearers. The approach can also be used to replace normal speaking or singing voices.

    LIPPS -- A Virtual Teacher for Speechreading Based on a Dialog-Controlled Talking-Head BIBAKFull-Text 621-629
      Hermann Gebert; Hans-Heinrich Bothe
    People with decreasing hearing ability are more dependent on alternative personal communication channels. To read the visible articulator movements of the conversation partner is one possible solution for understanding verbal statements. After giving an introduction to the principals of speech, visual speech & speechreading, we demonstrate the conception and implementation of a language laboratory for speechreading that is meant as an effective audio-visual complement and extension of classroom teaching. Further we show results of evaluation experiments and explain the functionality and interaction of the modules, the interaction between student, teacher, and virtual teacher and the structure of the pedagogical approach to teach speechreading with the help of a virtual teacher.

    The Need for Easy-to-Read Information on Web Sites BIBAKFull-Text 634-640
      Ulla Bohman
    Internet as a media for transmitting information requires higher reading skills from the user than information presented on paper. Therefor it is a great need of easy-to-read information on web sites in order to make the internet accessible for people with reading problems. For the web-information to be accessible, it must be easy to find, the web site easy to navigate and the text must be readable and understandable. The information should be in easy-to-read language and presented in a separate web-room.
