Web Accessibility

A Framework to Facilitate the Implementation of Technical Aspects of Web Accessibility BIBAKFull-Text 3-13
  Roberto Cícero de Oliveira; André Pimenta Freire; Débora Maria Barroso Paiva; Maria Istela Cagnin; Hana Rubinsztejn
The expansion of the internet has become apparent in recent years, both by the number of users, and by the number of services available on the network. Considering such an expansion it is essential that the content be accessible to all people, regardless their abilities or different disabilities. Thus, it is necessary that IT professionals dedicate time and effort in planning accessible online solutions. In this paper, we proposed the Homero framework in order to support the development of accessible interface layer of web applications. Developed using the PHP language, the Homero framework automates the generation of web pages in accordance with guidelines defined in Web Content Accessibility Guidelines (WCAG) 2.0. In order to provide evidence of the quality of web applications generated using the framework, an empirical study was conducted. The results showed the effectiveness of Homero to assist the development of accessible web applications, achieving level AAA in automatically detectable WCAG 2.0 success criteria.

Preserving Privacy -- More Than Reading a Message BIBAKFull-Text 14-25
  Susanne Furman; Mary Theofanos
Social media has become a mainstream activity where people share all kinds of personal and intimate details about their lives. These social networking sites (SNS) allow users to conveniently authenticate to the third-party website by using their SNS credentials, thus eliminating the need of creating and remembering another username and password but at the same time agreeing to share their personal information with the SNS site. Often this is accomplished by presenting the user with a dialog box informing them that they will be sharing information. We were interested in determining if SNS users authenticating to a third-party website with their SNS credentials, were reading the informational message and if changing the message format would impact the choice to continue or cancel. Format type did not alter the participant's choice to continue. Eye-tracking data suggests that the participants who chose to continue read some of the words in the message.

An Ergonomic Evaluation of the Adaptation of Polish Online Stores to the Needs of the Elderly BIBAKFull-Text 26-36
  Krzysztof Hankiewicz; Marcin Butlewski; Wieslaw Grzybowski
Recently websites have been a key intermediary in the exchange of information. The share of trade conducted based on online services transactions is also dynamically growing. Among people using online services and communicating this way, are now also the elderly. These are often people whose first contact with these technologies occurred during adulthood. Many of elderly people did not use a computer in their work, and their first contact with the Internet has been during their retirement. In conclusion, the currently operating focus in Poland on young online shoppers is faulty. With the increasing proportion of elderly people in Polish society and the dissemination of computer technology among them, the need for senior-friendly online stores will grow. The choice of this form of purchase will be decided by convenience, price, range of goods and delivery terms. However, the ultimate determinants of whether elderly users will enjoy the benefits of online shopping are the ergonomic features of services, particularly criteria such as: security, ease of use, rule transparency and ascetic aesthetics.

A Showcase for Accessible Online Banking BIBAKFull-Text 37-45
  Sebastian Kelle; Christophe Strobbe; Gottfried Zimmermann
Online banking systems pose especially high requirements to web architectures with particular respect to the end-user interface. Although the number of online banking users is steadily increasing, they commonly face "one-size-fits-all" user interfaces rather than personalized user interfaces that are tailored to their individual needs and preferences. In this paper we present a prototypical online banking demonstrator that is based on the Global Public Inclusive Infrastructure (GPII), a new technical framework for the development, identification and delivery of accessibility services, assistive technologies and automatic personalization capabilities; and on the Universal Remote Console (URC) technology, a framework for pluggable user interfaces.

Using Eye Tracking to Understand the Impact of Cognitive Abilities on Search Tasks BIBAKFull-Text 46-57
  Efi A. Nisiforou; Eleni Michailidou; Andrew Laghos
Nowadays, there is an increase of studies that examine individuals' cognitive characteristics in correlation to visual perception. The present study investigated the association between cognitive abilities and Web page complexity. Specifically, differences within simple, medium and complex Web pages were observed among the field dependent, independent and mixed cognitive groups via a task completion time with the use of the eye tracking technology. The results showed that task completion time is significantly different in medium and complex pages between the FD and FI users, while, in the simple pages, no statistical differences appeared. Furthermore, it was supported that users' FD-I cognitive construct style can be identified using innovative techniques like eye tracking studies by analyzing users' scan path and heat maps.

Making Web Pages and Applications Accessible Automatically Using Browser Extensions and Apps BIBAKFull-Text 58-69
  Ignacio Peinado; Manuel Ortega-Moral
Web accessibility depends on three factors: the semantics of the web contents, the assistive technologies (ATs) and the capabilities of the web browsers (Fernandes, Lopes, & Carriço, 2011). Moreover, the widespread implementation of Rich Internet Applications (RIAs) poses new challenges for ensuring the equality of access to dynamic web content. This paper presents the development of a solution that will automatically activate the accessibility features and the available ATs in two web browsers that take more than 50% of web browsers market share, and depending on the expressed needs and preferences of the user. The two extensions presented will take advantage of the infrastructures developed in CLOUD4all and APSIS4all in order to inject CSS and JavaScript in any web pages, as well as activating non-out-of-the-box ATs, and hence guaranteeing access to both static HTML pages and Rich Internet Applications.

The German Web 2.0 Accessibility Survey BIBAKFull-Text 70-76
  Michael Pieper
The German BIENE award (Barrierefreies Internet Eröffnet Neue Einsichten / Accessible Internet Provides New Insights) happened to be a best practice competition for accessible websites organized by the social association "Aktion Mensch" and the endowment "Digitale Chancen". For the last 2010 competition 224 web pages have been checked for their barrier free accessibility. Web applications that facilitate interactive sharing of user generated content have been of particular importance. In this respect it soon turned out, that Web 2.0 services cannot only be made accessible by applying common design guidelines and ad-hoc adaptations. In addition to conventional software ergonomic verification procedures, accessibility validation has to rely on sociological reasoning about unique Web 2.0 entities and corresponding usage obstacles. Empirically these considerations have been conceptualized by an online survey amongst 671 respondents with all kinds of different disabilities, carried out by "Aktion Mensch".

Automated Accessibility Evaluation Software for Authenticated Environments BIBAKFull-Text 77-88
  Elisa Maria Pivetta; Daniela Satomi Saito; Carla da Silva Flor; Vania Ribas Ulbricht; Tarcísio Vanzin
Web accessibility has been the subject of much discussion regarding the need to make Web content accessible to all people, regardless of their abilities or disabilities. While some testing techniques require human intervention, accessibility can also be evaluated by automated tools. Automated evaluation tools are software programs that examine the code of Web pages to determine if they conform to a set of accessibility guidelines that are often based on the Web Content Accessibility Guidelines Version 2.0 (WCAG 2.0), developed by the World Wide Web Consortium (W3C). In this context, the purpose of this study is to analyze an automated software program for evaluating authenticated environments and verify the usability of this tool, since automated systems require precision and reliability in terms of both results and use in any type of environment. With this in mind, this paper aimed at evaluating the ASES software by means of a heuristic evaluation carried out by three experts. The analysis revealed major accessibility problems, as well as improper functioning of available tools and inconsistency of results. Furthermore, ASES was found to have problems of efficiency, interaction, validity, and reliability in the results presented. Considering that this is an open-source accessibility testing tool that can be found on a government web site, the correction or improvement of the system's deficiencies identified in this study is highly recommended, as there is a lack of software available to evaluate authenticated environments.

High-Literate and Low-Literate User Interaction: A Comparative Study Using Eyetracking in an Emergent Economy BIBAKFull-Text 89-100
  Letícia Régis Di Maio; Ney Wagner Freitas Cavalcante; Simone Bacellar Leal Ferreira; José Luiz dos Anjos Rosa; Aline Silva Alves
The information technology including, increasingly, the services offered to citizens, this necessitates the development of web pages accessible to everyone, regardless of education level. Whereas a significant portion of the Brazilian population is within the low literacy profile, the objective of this research was to analyze the different forms of navigation among users of high and low literacy. Data were collected through user testing through eye tracking. The experiences of interaction were performed from two tasks initiated in the Google search engine and completed in two popular sites. At the end, some suggestions were proposed interface improvements.

Practical Eye Tracking of the Ecommerce Website User Experience BIBAKFull-Text 109-118
  Wilkey Wong; Mike Bartels; Nina Chrobot
Eye tracking is a productive tool in researching the user experience of ecommerce websites. Because information throughout the online path to purchase is communicated visually, gaze behavior is among the most effective and informative means of testing the extent to which a given ecommerce site facilitates a smooth transaction. The process of analysis typically involves examining the characteristics and patterns of visual attention during the online shopping process. Eye-tracking metrics are used in conjunction with data-based visualizations and traditional usability techniques to answer a variety of questions about the online shopping process. Principles of appropriate design, execution and analysis of an ecommerce eye-tracking study are discussed, along with relevant case examples.

An Accessible CAPTCHA System for People with Visual Disability -- Generation of Human/Computer Distinguish Test with Documents on the Net BIBAKFull-Text 119-130
  Michitomo Yamaguchi; Toru Nakata; Takeshi Okamoto; Hiroaki Kikuchi
We propose a new scheme of CAPTCHA that does not become a perceptual barrier for disable people. Our CAPTCHA system generates the tests in verbal style, so its use is not limited in specific perceptual channels. The tests are composed of several phrases and there are two kinds of tests: Human users try to (1) distinguish a phrase of strange meaning from others, and (2) identify the common topic among them. In our test we utilize open documents for material. Note that there is quite a large amount of documents on the net, so we can generate brand-new tests every time. One may say that adversaries can look for the phrases over the Internet and get several hints. Our system hides the sources by substituting the consonants of the phrases against such an attack. The mechanism is designed to imitate the phenomenon called "consonant gradation" of natural languages.

Design for all in the Built Environment

City -- Mass Communication Space -- Access to Information in Relation to the Composition of the City BIBAKFull-Text 133-142
  Agata Bonenberg
Streets and squares in the cities were created so that they could constitute public space -- space of a social integration. Important social binding agent is a common, direct access to information, ability of passing it on and undertaking actions appropriate to its response. In an era of information revolution, new information and communication technologies enriched social contacts. Access to information no longer requires direct interpersonal contact due to which the contact became less related to city space. The subject of the article is the evolution of city space with relation to the access to information. The contemporary closing of which is the phase of multimedia mass communication and city spaces designed for information society.

      Jerzy Charytonowicz; Dzoana Latala-Matysiak
    Technical progress, thanks to which the contemporary kitchen achieved the current shape, initiated changes going towards adapting the kitchen equipment to widely understood needs of the user. The whole of current studies concerning the ergonomics of the kitchen area in apartment is insufficient, it doesn't fulfill contemporary designing requirements. Verifying and updating previous research, supplementing them and presenting in the form of designing criteria is essential. Taking into consideration all needs of contemporary family, diverse by age, fitness and agility, it is necessary to provide optimal and widely understood quality of kitchen area.

    A Virtual Dressing Room for People with Asperger's Syndrome BIBAKFull-Text 163-170
      Line Gad Christiansen; Anthony Lewis Brooks; Eva Petersson Brooks; Torben Rosenørn
    Using the Virtual Dressing Room (VDR) system, which is created as a research project between different companies and universities in Denmark and funded by the Danish National Advanced Technology Foundation, a usability study has been conducted with people with Asperger's Syndrome (AS), the initial aim was to determine if the people with AS would use the VDR system and understood it, as a second aim, the findings was used to determine a set of design goals. Seven teenagers with AS participated in the study, in the age range from 15 to 17 years old. A questionnaire was used before the study, to determine the target groups interests and how/if they purchase clothes. Through observations and video recording of the usability study, a qualitative interaction analysis provided a set of design goals to be used when designing for this target group. The goals emphasized the importance of an easy accessible and consistent solution with a limited amount of options and the importance of the user's own preferences.

    MoviBed -- Sleep Analysis Using Capacitive Sensors BIBAKFull-Text 171-181
      Maxim Djakow; Andreas Braun; Alexander Marinc
    Sleep disorders are a wide-spread phenomenon that can gravely affect personal health and well-being. An individual sleep analysis is a first step in identifying unusual sleeping patterns and providing suitable means for further therapy and preventing escalation of symptoms. Typically such an analysis is an intrusive method and requires the user to stay in a sleep laboratory. In this work we present a method for detecting sleep patterns based on invisibly installed capacitive proximity sensors integrated into the bed frame. These sensors work with weak electric fields and do not disturb sleep. Using the movements of the sleeping person we are able to provide a continuous analysis of different sleep phases. The method was tested in a prototypical setup over multiple nights.

    Contribution of Augmented Reality Solutions to Assist Visually Impaired People in Their Mobility BIBAKFull-Text 182-191
      Benoît Froissard; Hubert Konik; Alain Trémeau; Éric Dinet
    The study is dedicated to analyze opportunities of augmented reality eyewear solutions for visually impaired people in a context of mobility. In order to perfectly understand the needs of low vision individuals, their expectation towards visual aids, and to clearly define crucial requirements, an experimental study has been carried out in a re-adaptation clinic. 58 patients with different visual pathologies have been carefully selected by vision-care professionals. During experiments and interviews, professional techniques developed for teaching patients to efficiently use their visual residual capabilities have been analyzed. One of the main objectives was to show the usefulness and the importance to put in the loop all actors to be able to derive relevant knowledge essential to success in the design and in the development of new visual aids dedicated to facilitate mobility of low vision people. The first results are encouraging and they tend to demonstrate the interest to use embedded augmented reality systems in order to propose helpful solutions easily adaptable to the specificities of the different visual troubles affecting mobility.

    The Evolution of Public Hygiene and Sanitary Facilities in the Context of Urbanization Processes and Social Conditions BIBAKFull-Text 192-203
      Anna Jaglarz
    The evolution of public places and facilities for personal hygiene is directly related to the history of urbanization and to people awareness of public health and its relationship to sanitation. Throughout history, this awareness has varied extremely both between cultures and periods and produced widely disparate responses in spite of virtually identical needs. Availability of technology, variable over the centuries, was dependent on the social and cultural requirements of the times. On the one hand, the new technologies developed in order to meet the growing needs, on the other technological achievements were ignored and not used by years. An example can be a legacy and the inheritance from civilizations such as the Cretans and Romans who accomplished amazingly great feat as regard engineering and the production of hygienic and sanitary facilities, with supplying the warm and cold running water, flushing systems, steam rooms and a lack of such appliances centuries later, when because of the civilization development the basic technology would seem to be far more advanced. It is possible to say that the form of hygienic and sanitary environment of man has always been reflecting the social and economic aspects, which are a consequence of widely understood, changeable, both individual and social needs, and of the cultural and technical progress of civilizations resulting from them. Experiences and achievements of previous generations are a base of the contemporary model of the societies life. Understanding and analysis of the contemporary needs related to public hygiene and sanitary area and possibilities of its shaping should be based on an analysis of earlier experiences in this field.

    Tradition and Innovation in Architectural Education BIBAKFull-Text 204-214
      Nina Juzwa; Katarzyna Ujma-Wasowicz
    The presentation is devoted to the problem of introducing computers into the educational process during the last semester of architectural studies for a master's degree. Non-linear structures become almost the principle of design through modifying the traditional, orthogonal image of architecture. Students are open to the creation of concepts which modify the traditional orthogonal spatial system of architecture.
       The two-level system of teaching at the course of graduate studies results in students with varying degree of preparation being admitted. This fact in conjunction with large exercise groups and a relatively short time allocated for the project require methodical preparation of the classes. The shaping of the future form of an object can be presented using a freehand sketch, mock-ups or computer models. These tools correspond to the subsequent three phases of the development of the project: exploration of ideas and the context of the environment, working out variants for decisions on functional solutions, spatial and aesthetic concretization of design solutions. In the opinion of the authors of the paper extending the discussion in the first two phases of the teaching process, that take place without the use of computer drawing, leads to a higher originality of the solutions and to an increased efficiency in their preparation.
       The above thoughts, supported by examples, are the subject of this presentation.

    Analysis of Natural Lighting with Regard to Design of Sustainable Office Buildings in Poland BIBAKFull-Text 227-236
      Dariusz Masly; Michal Sitek
    The study was a part of a larger research project which was devoted to simulation-based design analysis for daylit office spaces in Southern Poland. The paper consists of two main parts. The influence of various facade systems, light-shelves and fixed shading systems on daylight factor in the analysed office space is presented in the first part. These introductory analyses allowed to identify the optimal facade for an office building. The second part of the project included the comprehensive analysis of selected best performing architectural solutions. These analysis examined how lighting conditions were changing during typical time of an office work throughout the year. Illuminance levels and visual comfort were analysed. New issues like the performance of external retractable venetian blinds were added. This paper also investigates how state of the art simulation technology can be used to integrate natural lighting design strategies into the early stages of architectural design process.

    Induction Machine Faults Leading to Occupational Accidents BIBAKFull-Text 237-245
      Beata Mrugalska
    In order to obtain high performance and safety degree in machine operation it is necessary to identify potential machine faults. Such faults may have an effect on the machine itself but may also lead to accidents at work. Thus, the activities aiming at the identification of the relation between the failure causes and their effects seem to be necessary to be undertaken. With this purpose, the first part of the paper concerns the analysis of machine faults. In order to achieve it, induction machines are chosen and are widely discussed. In the next part of it the issues of occupational risk are presented, in particularly statistical data about accidents at work in Polish enterprises. It allows to determine the problem of faults and their influence on workers' safety in industrial environment.

    The Controversy between the Human Factors and Ergonomics Demands and the Current Designing Rules of Contemporary Stadiums BIBAKFull-Text 246-256
      Zdzislaw Pelczarski
    The research concerns determining factors of the development of architectural form of modern stadiums and leads to conclusion that the size and shape of the field of game, which is the field of observation, is derivative of the game rules, with no any regard to the factors defining visual comfort of spectators. These game rules, having been invented over one hundred years ago, had not account for the entertaining character of the action on the pitch, nor for the need of co-existence between the field and huge spectator stands.
       The interiors of future stadiums should be shaped considering correct relationship between the needs of spectators and arena. The appropriate standards of the visibility, adjusted to anatomical features of human eye perception, should have the supreme priority in these relationships, consequently causing, as an outcome of these corrected standards, changes in the shape and size of the arena.

    Kitsch in Architecture -- Contemporary Polish Hotels BIBAKFull-Text 279-290
      Elzbieta Trocka-Leszczynska; Joanna Jablonska
    Kitsch has become embedded in the landscape of Polish cities and villages and is especially well represented in the architecture of hotels. It portrays society's relentless yearning for the wealth and tradition of extensive old-style mansions combined with economical building materials, restrictions of computer aided design and the desire to pander to mass tastes. In effect, there are produced over-scaled, not ergonomic, cheap accommodation facilities, filled with plastic and gypsum ornaments, which are unfamiliar to local culture. Drawing on a number of case studies this paper investigates the causes of kitsch manifestation and its effect on the surroundings and proposes methods of protecting the urban and rural landscape from devastation.

    Day-Lighting and Sun Protection in Hospital Facilities -- Assessment of the Used Solutions BIBAKFull-Text 291-302
      Joanna Tymkiewicz; Magdalena Jamrozik-Szatanek
    The paper is a recapitulation of research into hospital buildings, focused on defining the advantages and disadvantages of the applied sun-protection systems and indication of the types of benchmark solutions. Proper selection of sun-protection systems in health care units is very important, because it contributes to creating the conditions of day lighting and their impact on patients' physiology. Moreover, sun protection systems influence the architecture of buildings -- their external image and aesthetics of the interiors, ergonomics of rooms, providing comfort for the main groups of users: patients and medical staff, and contributing to energy-efficiency of buildings. The scope of the presentation is to draw particular attention to the complexity of this issue from users' perspective.

    Notheime -- Ergonomically Designed Crisis Houses of the Building Cooperative "Schlesische Heimstätte" BIBAKFull-Text 303-313
      Jadwiga Urbanik
    In Germany after World War I in years 1918-1923 inflation was a decisive negative economic factor. Since 1923 the inflation process started to increase suddenly. Since July 1923 German currency lost its function of means of payment. Cash was changed into valuables as quickly as possible. Economic development was totally crippled.
       In Wroclaw need for flats was enormous. It was much bigger than in other German cities. In June 1919 building cooperative "Schlesische Heimstätte", provinzielle Wohnungsfürsorgegesellschaft m.b.H (Silesian Homestead, provincial company supporting housing construction, Ltd.), was founded in Wroclaw as part of Prussian housing act. It acted under the aegis of Ministry of Social Care.
       In the first years after WWI, at the time of great postwar crisis, Ernst May -- a young architect beginning his career, was appointed as a manager of "Schlesische Heimstätte". The company was to supply people of modest means with healthy and properly furnished flats at low prices.
       In the first half of the twenties so called crises houses (Notheime) were proposed. The propositions of the smallest houses were introduced in 1919-1920. They were dwelling summer houses with a room, small barn and toilet. They were to be enlarged or replaced with new buildings after the economic situation would have improved.
       Because of the lack of building materials after WWI, building cooperatives used substitute materials. Traditional natural materials were recommended in all designs -- walls built from bricks and plastered, wooden truss and roof covered with tile. In order to find cheap solutions old local building materials were used. Walls could be built from dried clay blocks, limestone, calcareous slag or wood. Shingled or even thatched roof houses were suggested.
       A lot of attention was paid for economically and ergonomically designed layout of crises houses. They were to solve the enormous dwelling problems in Wroclaw and Silesia.

    Federated Databases and Supported Decision Making BIBAKFull-Text 337-347
      Denis Anson; Yao Ding
    Currently, information required to make informed choices of appropriate assistive technology products is scattered among broad, general-purpose databases and narrow, focused databases. The vocabulary used to describe features has not been standardized, and can be very hard to interpret by end-users of assistive technology. The described project will create a federated Unified Listing of assistive technologies for information and communication technologies, and develop a Shopping Aid, using information provided by the individual to filter products and services from the Unified Listing to those that are relevant to the individual. By examining needs information across users, the Shopping Aid will be able to suggest additional needs that are common among people like the user, and to make recommendations for upgrading choices when the probably benefit exceeds the individual's cost of change.

    Evaluating the Global Public Inclusive Infrastructure: Cloud4all Evaluation Framework BIBAKFull-Text 358-367
      Eleni Chalkia; Juan Bautista Montalva Colomer; Silvia de los Rios Perez; Ivan Carmona Rojo
    Moving rapidly into digital economy expands the need for accessibility coming from the growing number of people with disabilities, in various contexts. Additionally, ubiquitous computing has amplified the need for interactive systems to be able to adapt to their context of use, enhancing their utility while preserving usability. Cloud4all project [0] aims to develop a complete new paradigm in accessibility, by replacing adaptation of individual products and services, with auto-configuration of any mainstream product or service, using cloud technologies to activate and augment any natural accessibility the product or service has, based upon a set of the user's Needs & Preferences (N&Ps). In order to assess this goal, Cloud4all has developed an evaluation framework, as part of the User Centred Design (UCD) iterative process. This paper provides an overview of the 1st pilots' evaluation framework, together with ideas and plans about the general framework of the pilot test.

    Federating Databases of Assistive Technology Products: Latest Advancements of the European Assistive Technology Information Network BIBAKFull-Text 378-389
      Valerio Gower; Renzo Andrich; Andrea Agnoletto
    Detailed information on the Assistive Technology (AT) Products available on the market is of paramount importance for many different stakeholders: people with disabilities and their family members, AT professionals, manufacturers/suppliers of AT products, researcher and developer, and policy makers. Since 2005 the organizations responsible for the major European AT information systems have joined together to create the European Assistive Technology Information Network (EASTIN). The core of the EASTIN network is the web portal www.eastin.eu that provides, in all the EU official languages, information on AT products and related material. In the last few years the EASTIN association promoted a series of projects aimed at improving the web portal and expanding the network to cover all the EU countries. This paper describes the main results of such projects.

    The GPII on Desktops in PCs OSs: Windows and GNOME BIBAKFull-Text 390-400
      Javier Hernández Antúnez; Colin Clark; Kasper Markus
    Since The Global Public Inclusive Infrastructure [1] aims to become an international standard, one of the biggest challenge of the GPII project is to support the many Operating Systems that are running in our Personal Computers. Nowadays, we make an extensive use of personal computers -- both laptops and desktops -- and their Operating Systems in a lot of circumstances, and as a result of this, we can say that a lot of people could have difficulties when they start using a new computer. Add to this the diversity of different software applications that people use and their many different restrictions of use, and the problem becomes bigger when a person needs some Assistive Technology [2] to use a computer efficiently. As part of the Cloud4all project, the implementation of the GPII on PC OSs is taking place to address these problems. By having a first version of this implementation, the GPII is ready to help the users to solve their problems when using a new PC's OS for the first time.

    In this paper, we present the main features of the Amara project, and its impact on the accessibility landscape with the use of innovative technology. We also show the effectiveness of volunteer communities in addressing large subtitling and translation tasks, that accompany the ever-growing amounts of online video content. Furthermore, we present two different applications for the platform. First, we examine the growing interest of organizations to build their own subtitling communities. Second, we present how the community-generated material can be used to advance the state-of-the-art of research in fields such as Statistical Machine Translation with focus on educational translation. We provide examples on how both tasks can be achieved successfully.

    AT and GPII: Maavis BIBAKFull-Text 412-420
      Steve Lee; Gregg C. Vanderheiden; Amrish Chourasia
    Maavis is a computer framework that provides an extremely simple way to perform common place computer activities like playing media, viewing photos, accessing web information and making video calls. It is ideal for use with a touch screen. A fundamental principal is that it does not appear to be a computer and yet affords access to computer technology that is of benefit and interest to older users, especially those with age related mental health issues. It also has applications for people with learning difficulties or physical disabilities, or even simple kiosk interfaces as it is designed to work best with a touch screen. Integration of Maavis with the GPII has undergone successful validation tests and further development work is ongoing.

    Requirements for the Successful Market Adoption of Adaptive User Interfaces for Accessibility BIBAKFull-Text 431-442
      Matthias Peissner; Andreas Schuller; Daniel Ziegler; Christian Knecht; Gottfried Zimmermann
    The concept of adaptive user interfaces is a promising solution for providing users with a wide range of individual needs with accessible technology. Developers only have to implement one generic solution to offer a multitude of individually optimised concrete user interfaces. Whereas a lot of technical functionalities and characteristics of adaptive user interfaces are already solved, there is still no widespread market adoption of adaptive UI technologies. This paper presents a collection of requirements for adaptive user interface systems that can enable widespread market adoption. Furthermore it identifies strategies and individual answers, how these requirements can be addressed and met in future systems building on the Prosperity4all approach. It gives a comparison of existing research solutions and how they compare with the stated requirements.

    Prosperity4All -- Setting the Stage for a Paradigm Shift in eInclusion BIBAKFull-Text 443-452
      Matthias Peissner; Gregg C. Vanderheiden; Jutta Treviranus; Gianna Tsakou
    This paper provides an overview of the recently started Prosperity4All project. Prosperity4all aims at a paradigm shift in eInclusion. It focuses on developing the infrastructure to allow a new ecosystem to grow; one that is based on self-rewarding collaboration, that can reduce redundant development, lower costs, increase market reach and penetration internationally, and create the robust cross-platform spectrum of mainstream and assistive technology based access solutions required. This will be done through a process based on true value propositions for all stakeholders and resulting in a system that can profitably serve markets as small as one, at a personally and societally affordable cost.

    People with disabilities are disproportionately affected by systemic global economic problems such as digital exclusion, income disparity, unemployment and poverty. The Prosperity4all project, an international consortium supported in part by the European Union FP7 program, is seeking to address the economic exclusion of consumers and producers at the margins, including people with disabilities. This article discusses the economic or business design models being considered in this emerging initiative. Like the work that the platform supports, the platform itself must be designed for diversity.

    A Novel Infrastructure Facilitating Access to, Charging, Ordering and Funding of Assistive Services BIBAKFull-Text 462-473
      Gianna Tsakou; Helen C. Leligou; Nikos Katevas
    Given that, nowadays, access to ICT is required for almost any kind of education, employment and commerce form, and is increasingly required for travel, it is mandatory to focus on integrating groups of users with any type of disability at a personally and societally affordable cost. In this paper, we outline an ICT-enabled novel infrastructure that significantly facilitates user access to a large set of specialised assistive services and enables small ICT players (e.g. web entrepreneurs) to develop novel services "on user/user group demand" supported by crowd funding. Our vision is to create an infrastructure that can move ideas more quickly from conception to market and consumer availability, that can be more efficient by being better targeted to user needs, that can move users closer to researchers and developers to ensure that the full range of needs are better addressed and that can reduce both the development and operation cost of assistive services. The system we propose consists of the Assistance on Demand (AoD) service infrastructure which aims to be a gateway for accessing on demand diverse types of human and machine-based assistive services. This AoD is accompanied by a flexible payment infrastructure that aims at enabling, for all relevant stakeholders (end users, service providers, etc.), the easy, flexible and reliable handling of multiple bills for different services, while at the same time supporting crowd-funding, as necessary, for user-driven assistive technology (AT) or service development. In this paper, we present the state-of-the-art technologies and approaches that will serve as the basis for the design and development of the AoD and payment infrastructures and then we discuss the requirements that these intertwined systems have to fulfill and draw high-level design directions.

    Prosperity as a Model for Next-Generation Accessibility BIBAKFull-Text 474-482
      Gregg C. Vanderheiden; Jutta Treviranus; Colin Clark; Matthias Peissner; Gianna Tsakou
    We propose a multisided platform approach that is user-based but seeks to provide an infrastructure that supports all stakeholders, making it easier for vendors to design, market and support access features, products, and services and that makes it easier for consumers to find, secure, and use access features, products and services, individually or mixed, on any device they encounter. The system is designed to support use by both mainstream and assistive technology developers and to draw new people into the ecosystem in new roles including developers as resources and users and clinicians as developers. Central to this latter role is a developer space that provides rich resources in the form of tools, component, frameworks, service infrastructures, guidelines, how-to's, mentors, testers, and marketing aids to help both experienced and new developers enter the market and to broaden the range of people contributing to include both non-disability-related researchers/developers and less technical consumers and professionals.

    The incidence of disability is increasing. As we move to a more digital world, people with disabilities, older people, and those with literacy and digital literacy problems face the prospect of losing out due to lack of access to information and communication technology. The rehabilitation engineering research center (RERC) on universal interface and information technology access seeks to promote a new approach to accessibility. This approach involves creating a new infrastructure for the development and delivery of AT and built-in access features. This effort is known as the Global Public Inclusive Infrastructure (GPII). This RERC will move the idea of GPII from laboratory prototypes to real-world implementation. A library GPII system and a cloud-based decision support tool for assistive technology selection are currently under development. The RERC will also support technology transfer and development of standards to promote accessibility.

    The Library GPII System BIBAKFull-Text 494-505
      Gregg C. Vanderheiden; Amrish Chourasia; Jim Tobias; Steve Githens
    This paper describes the library GPII system (LGS), the first real-world implementation of the GPII (Global Public Inclusive Infrastructure) system. The GPII aims to utilize cloud computing to create the infrastructure to provide affordable assistive services whenever and wherever a user demands them. The interactions of the different stakeholders in the library ecosystem present various challenges to implement such a system. These stakeholders include the library patrons, library staff, government, publishers, software developers and vendors. The development of the LGS will happen in three phases: needs analysis, development and empirical evaluation. Libraries of various sizes and resources will be involved in the development and evaluation of the LGS. We are currently in the first phase and the results of our stakeholder analysis work to-date are presented.

    Creating a Global Public Inclusive Infrastructure (GPII) BIBAKFull-Text 506-515
      Gregg C. Vanderheiden; Jutta Treviranus; Manuel Ortega-Moral; Matthias Peissner; Eva de Lera
    The current accessibility ecosystem that develops and delivers both assistive technologies and access features in mainstream technologies is not able to keep up, provide the diversity of solutions needed, nor reach more that a small portion of those who need them. To address this a large scale effort was proposed to provide an infrastructure that would allow the ecosystem to evolve into a quite different and purportedly more effective and efficient ecosystem. This paper describes the infrastructure, reports on the progress in securing funding and implementing the various components of the infrastructure. A roadmap for the implementation and a timeline are provided along with a discussion of the major challenges going forward.

    Individuals with disabilities are often unable to find assistive technology that meets their needs. While different databases of assistive technologies currently exist, individuals with disabilities are not aware of all of them and unable to take advantage of them. The Global Public Inclusive Infrastructure (GPII) Unified Listing's objectives are 1) to create a single unified listing, that covers not only assistive technologies that relate to accessing ICT but also includes access features built directly in to main-stream ICT as well. 2) to create an open marketplace of accessible and personalizable solutions. The unified listing will be bidirectionally federated with databases such as EASTIN. Development of a method to harmonize and federate the data contained in the different databases is complete and work is underway to create a mechanism to extract information relevant to ICT access from the federated data.

    People with communication needs use Assistive Technology (AT) to participate in society, be at the family, school among others. There is a variety of different Alternative and Augmentative Communication (AAC) devices due to end-users have different communication needs. AraBoard is an AAC tool developed with the aim to facilitate the functional communication to people with complex communication needs. In this paper, AraBoard tool is presented. In order to ensure the quality of the tool, an accessibility evaluation has been carried out. Following a methodical approach, two main steps have been followed in the evaluation process: (1) Two lists of checkpoints have been developed based on the study and analysis of accessibility standards and related work in the domain of AAC; (2) An evaluation using these resources has been conducted by accessibility experts. The results from the study indicate a high level of accessibility in AraBoard tool, besides some suggestions about new requirements to integrate in the tool have been obtained.

    Four Data Visualization Heuristics to Facilitate Reflection in Personal Informatics BIBAKFull-Text 541-552
      Andrea Cuttone; Michael Kai Petersen; Jakob Eg Larsen
    In this paper we discuss how to facilitate the process of reflection in Personal Informatics and Quantified Self systems through interactive data visualizations. Four heuristics for the design and evaluation of such systems have been identified through analysis of self-tracking devices and apps. Dashboard interface paradigms in specific self-tracking devices (Fitbit and Basis) are discussed as representative examples of state of the art in feedback and reflection support. By relating to existing work in other domains, such as event related representation of time series multivariate data in financial analytics, it is discussed how the heuristics could guide designs that would further facilitate reflection in self-tracking personal informatics systems.

    Measuring the Perception of Facial Expressions in American Sign Language Animations with Eye Tracking BIBAKFull-Text 553-563
      Hernisa Kacorri; Allen Harper; Matt Huenerfauth
    Our lab has conducted experimental evaluations of ASL animations, which can increase accessibility of information for signers with lower literacy in written languages. Participants watch animations and answer carefully engineered questions about the information content. Because of the labor-intensive nature of our current evaluation approach, we seek techniques for measuring user's reactions to animations via eye-tracking technology. In this paper, we analyze the relationship between various metrics of eye movement behavior of native ASL signers as they watch various types of stimuli: videos of human signers, high-quality animations of ASL, and lower-quality animations of ASL. We found significant relationships between the quality of the stimulus and the proportional fixation time on the upper and lower portions of the signers face, the transitions between these portions of the face and the rest of the signer's body, and the total length of the eye fixation path. Our work provides guidance to researchers who wish to evaluate the quality of sign language animations: to enable more efficient evaluation of animation quality to support the development of technologies to synthesize high-quality ASL animations for deaf users.

    Metrics and Evaluation Models for Accessible Television BIBAKFull-Text 564-571
      Dongxiao Li; Peter Olaf Looms
    The adoption of the UN Convention on the Rights of Persons with Disabilities (UN CRPD) in 2006 has provided a global framework for work on accessibility, including information and communication technologies and audiovisual content. One of the challenges facing the application of the UN CRPD is terminology. The interpretation of concepts such as 'disability' and 'accessibility' builds on national traditions and metrics. A second challenge is implementation diversity: different nations and regions have their own interpretation of how media can be made accessible. A third challenge is the increasing number of platforms on which audiovisual content needs to be distributed, requiring very clear multiplatform architectures to facilitate interworking and assure interoperability. As a consequence, the regular evaluations of progress being made by signatories to the UN CRPD protocol are difficult to compare. Using case studies from three emerging economies (Argentina, Brazil and China) as well as industrialized nations including Canada, Denmark, the United Kingdom and the USA), this paper examines the situation facing television accessibility. Having identified and discussed existing metrics and evaluation models for access service provision, the paper identifies options that could facilitate the evaluation of UN CRPD outcomes and suggests priorities for future research in this area.

    A Comparing Study between People with Reduced Hand Function and Children BIBAKFull-Text 572-581
      Lena Lorentzen; Johan Eklund
    This study was conducted in collaboration with Tetra Pak® [1] measuring the hand strength, grip ability, hand size to judge how easy it was to open three packages with a group of 10 people with reduced hand function and 14 children, six years old. The result showed that the hand strength between the group with reduced hand function and the children was quite similar. Also the results from the grip ability test and their judgement of how it was to handle the package was similar. The size of the participants' hands was the only thing that really differed between the groups. This is an interesting input for designers developing products and packages that should be easy to use for children, but may be even more interesting for developing products where there is a need to exclude children or child protective packages.

    T-echo: Promoting Intergenerational Communication through Gamified Social Mentoring BIBAKFull-Text 582-589
      Yuki Nagai; Atsushi Hiyama; Takahiro Miura; Michitaka Hirose
    Intergenerational social mentoring, a mentoring system on social medium between the elderly and the young, will be the one of the platforms for the elderly to make use of their potential. The elderly could have more chances to communicate their knowledge and experience accumulated through their life to the next generations, and the young could try more challenges under the wisdom of crowds. Such systems should 1) have senior-friendly interface, 2) support the rich context-aware communication, and 3) blur some intergenerational gaps. In this paper, we propose "T-echo", a new trial system for intergenerational social mentoring. T-echo is based on the two concepts: "growing gamification" and "calendar-based interface." The field study 15 elderly joined showed that the calendar-notebook interface was friendly for the elderly and have rich contexts for mentoring. Furthermore, growing gamification could be a good mediator between the elderly and the young.

    Answers for Self and Proxy -- Using Eye Tracking to Uncover Respondent Burden and Usability Issues in Online Questionnaires BIBAKFull-Text 590-600
      Erica Olmsted-Hawala; Temika Holland; Elizabeth Nichols
    In a study of the American Community Survey online instrument, we assessed how people answered questions about themselves and other individuals living in their household using eye-tracking data and other qualitative measures. This paper focuses on the number of fixations (whether participants looked at specific areas of the screen), fixation duration (how long participants looked at the questions and answers), and number of unique visits (whether participants rechecked the question and answer options). Results showed that for age, date of birth and employment duty questions participants had more fixations and unique visit counts, and spent more time on the screen when answering about unrelated members of their household than when answering about themselves. Differing eye movements for proxy reporting suggest that answering some survey questions for other unrelated people poses more burden on respondents than answering about oneself. However, not all questions showed this tendency, so eye tracking alone is not enough to detect burden.

    Self-monitoring and Technology: Challenges and Open Issues in Personal Informatics BIBAKFull-Text 613-622
      Amon Rapp; Federica Cena
    Personal Informatics (PI), also known as Quantified Self (QS), is a school of thought which aims to use technology for acquiring and collecting data on different aspects of the daily lives of people. These data can be internal states (such as mood or glucose level in the blood) or indicators of performance (such as the kilometers run). Some research was conducted in order to discover the problems related to the usage of PI tools, although none investigated how common users use these tools for tracking their behavior. The goal of this paper is to provide some insights about challenges and open issues regarding the usage of PI tools from the point of view of a common user. To this aim, we provide a theoretical background of personal informatics and a brief review on the previous studies that have investigated the usage pattern of PI tools.

    There is a huge availability of videos that have been produced in a very fast and wide way, along with the popularity of Internet. The video authors should carefully consider the scenario since many users have different needs. It is important to keep in mind the user experience because involves a person's behaviors, attitudes, and emotions about using a particular system, for example, the video player. In addition, usability and accessibility of video players need to be considered. The object of this study is to examine users' needs, expectations and requirements for accessible videos. We developed an accessible video player to evaluate with users. We present the results in the form of guidelines, which highlight the characteristics of users; the characteristics that the video need to satisfy the users' needs and the context in which users commonly watch the videos.

    Can Animated Agents Help Us Create Better Conversational Moods? An Experiment on the Nature of Optimal Conversations BIBAKFull-Text 634-640
      Masahide Yuasa
    We describe a method using animated agents to investigate how humans recognize conversational moods. Conversational moods are usually generated by conversation participants through verbal cues as well as nonverbal cues, such as facial expressions, eye movements, and nods. Identifying specific rules of conversational moods would enable us to construct conversational robots and agents that are not only able to converse naturally, but pleasantly and excitedly. Additionally, these robots and agents would be able to assist us with proper action to generate improved conversational moods in different situations. We propose methods for developing agents that can help improve the quality of our conversations and facilitate greater enjoyment of life.
