Accessibility Challenge

The W4A Accessibility Challenge provides an opportunity for researchers and practitioners to showcase new and innovative technologies in the field of accessibility. The main goal of the Challenge is to encourage and accelerate the development of innovative and usable technologies, as well as provide feedback to the authors from end-users and experts in the field. The Challenge is where experimental systems and technologies are compared and evaluated both by the delegates and an independent panel of judges to identify the most significant advances in accessibility research that year.

In particular, we encourage undergraduate and graduate students to apply and showcase their thesis work in the field of accessibility.


Authors are required to attend the conference and present their work. Accessibility Challenge submissions are eligible for two types of awards:

  • Judges Award will be selected by five judges coming from different backgrounds such as academia, industry, and government, all relating to accessibility.
  • Delegates Award is selected by the audience, considering the best pitch and demo presentation at the conference.

Delegates Award

Please use the Delegates Award form to vote. The form will be open from 1.30pm to 5pm.

Panel of judges:

  • Matthew Atkinson, TPGi
  • Lori Samuels, NBC Universal
  • Hernisa Kacorri, University of Maryland
  • Uran Oh, Ewha Womans University
  • Dragan Ahmetovic, University of Milan, Italy

Challenge details for delegates

This year the W4A Web Accessibility Challenge will involve a 10-minute presentation including:

  • A slide pitch presentation
  • A video sent to the Challenge Chairs

During the presentation, each Challenge entrant will “pitch” their solution to the audience and articulate the innovative aspects of their technology and how it advances accessibility and usability. Their presentation will define the accessibility issue their technology solves, and describe the innovations one can expect to see during the demonstration video that will follow. The presenter may or may not allocate time for questions during the session.

Delegates will be given access to a virtual poll for selecting their favorite demo for the Web Accessibility Challenge Delegates’ Award. The poll will be distributed during the conference.

Submission materials and details
