The 10th International Cross-Disciplinary Conference on Web Accessibility W4A 2013 (use #w4a13)              

Co-Located with the 21th International World Wide Web Conference, WWW2013
13-15th May 2013 ñ Rio de Janeiro, Brazil

Theme: Bring Your Own Device!

Topics and Content
The WHO defines disability as ìa complex phenomenon, reflecting an interaction between features of a personís body and features of the society in which he or she livesî. Web Accessibility should address this interaction aspect of ìdisabilityî so that a wide range of problems are tackled.
While the need for and usage of assistive technologies may raise barriers that hinder the perception, the understanding, and the operation of the Web, other barriers may be caused by technological and situational impairments; think, for example, of people with low vision that use a tablet rather than an interactive board or a desktop.
Depending on the device used, the range of barriers being faced may vary. One could use assistive technologies to enhance the capabilities of a PC, a tablet or a smartphone; but one could also rely on desktop browsers on very large screens, interactive TVs, Web kiosks, gaming consoles, Web browsers in cars or gym equipment, interactive boards, tangible and natural user interfaces, or more esoteric devices. Due to particular interaction modalities, access to information or interactive services may be hindered or even prevented; due to the quantity and richness of information and services, ability to process information may be reduced; due to infrastructure (e.g., cellular networks in under-developed lands), certain services may become unusable; due to contingent factors, everybody can become situationally impaired; due to cultural or language differences, emotional or language barriers may ensue. In each of these situations, decoupling user interfaces from backend services could enhance interoperability both for people who rely on assistive technologies and those who donít, improving the quality of the experience regardless of oneís own devices.
We welcome therefore papers that explore these issues and their technological or methodological counterparts in the context of the Web, papers that assess solutions, that show similarities or differences between approaches, or that evaluate and compare methods and tools.
As a result, topics of interests include (but are not limited to):

- Accessibility-related issues of using oneís own devices
- Developing accessible user interfaces for different devices
- Coping with different interaction modalities
- Web authoring guidelines and tools
- Mobile accessibility
- User modeling and the adaptive Web
- Adaptation and transformation of existing Web content
- Design and best practice to support Web accessibility
- Technological advances to support Web accessibility
- End user tools
- Accessibility guidelines, best practice, evaluation techniques, and tools
- Psychology of end user experiences and scenarios
- Innovative techniques to support accessibility
- Universally accessible graphical design approaches
- Accessible graphic formats and tools for their creation.

Keynote Speakers
- Dr. Ed H. Chi ñ Staff Research Scientist at Google Inc.
- Prof. Clayton Lewis - National Institute on Disability and Rehabilitation Research

The Paciello Group Web Accessibility Challenge
The Sixth ìWeb Accessibility Challengeî, is organized to give an opportunity to researchers and developers of advanced Web accessibility technologies for showcasing their technologies to technical leaders in this area not only from academia and industry but also from end-users.
To encourage and accelerate development of innovative and practically usable Web accessibility technologies; the Challenge is one part of the conference in which new experimental systems and technologies are submitted, compared, and judged by our independent panel of experts as to the most significant advance in research technology in accessibility for that year.

Google Student Awards
The W4A 2013 Organising Committee are delighted to announce that, two awards, each of up to US$1200 (including registration), are available to support students to enable them to attend W4A 2013. We now invite applications with a deadline of February 28th, 2013.
The Third ìStudent Awards Programmeî, is organised to give an opportunity to high quality students with limited funding to attend the W4A Conference.
Our deadlines have been chosen to give as much time as possible to allow successful applicants to make their travel and accommodation arrangements.
Students with interests related to this yearís topic are encouraged but it is certainly not a requirement as all students with an interest in accessibility technologies are welcome to apply.

We will accept position and technical papers, and short communications.
Position papers should only be submitted as a communication of (up to 4-pages) whereas technical papers should be in full paper format (up to 10-pages).
The official language of the Conference is English. Submission details are available at <>

This years W4A is endorsed by the IW3C2 in cooperation with the ACM and its Special Interest Groups SIGACCESS, SIGWEB and SIGCHI.
The general conference is supported by IBM Research and The Zakon Group. The Web Accessibility Challenge is sponsored by The Paciello Group, and the Student Awards are sponsored by Google.
Please refer to the sponsors page: <>.

While 'Bring your own device!' is this year theme, please don't be deterred if this somewhat unique area is not yours.
We would like to see all quality work on Web Accessibility regardless of the particular field within accessibility.
The overriding reason for a paper being accepted is its high quality in relation to the broad area of Web Accessibility.
