Automation for Accessibility

This year’s special theme is “Automation for Accessibility”. There’s been a revolution in accessibility and assistive technology with the standardization of automation platforms and the lower costs of machine learning and artificial intelligence. What are today’s solutions? What will be the future?

Automation for Accessibility covers a broad spectrum of evaluations, individual adaptations, and Machine Learning/Artificial Intelligence solutions. We therefore particularly welcome submissions that address the following topics:

  • Automation for Accessibility Evaluations
  • Security, Ethics, and Inclusion in Automation
  • Automation and Internet of Things/ Web of Things
  • Developments in Automation for the Web
  • Automation within Mobile and Wearable Technology
  • Adaptive Assistive Technology
  • Customizable Learning and Learning Technology
  • Automation and Inclusive Technology
  • Automation Transforming User Experience
  • Adjustments for Older Adults
  • Automation for People with Learning Difficulties
  • AI and Machine Learning for User Needs
  • Standards for Automation
  • Expectations and Evaluation of Automation by People with Disabilities
  • Adapting to User Needs Using Limited or Small Data
  • Infrastructure for Broad Automation

But as in every year, don’t be deterred by the theme; all topics related to web accessibility are welcome as are papers dealing with wider aspects of digital accessibility and universal access.
