The Billion-User Blind Spot: Who, What, and How of Digital Accessibility
Sean J. Keegan
Stanford University - Office of Digital Accessibility

Abstract: "Have you ever considered how someone who cannot see a screen uses a mobile app? Or how someone who can't use a mouse navigates a website? Technology has the power to connect, but it can also create unintentional barriers that exclude millions."

"Together we will explore how people with disabilities can use assistive technologies - including screen readers, alternate mice, adaptive keyboards, and braille displays - to navigate digital content. Understanding user experiences along with existing digital accessibility standards (WCAG) can help translate design and development decisions into accessible web and mobile app development. We will also discuss how the increased reliance of AI tools represents a 'double-edged sword' for digital accessibility and access for people with disabilities."

Biosketch: Sean J. Keegan is the Director for the Office of Digital Accessibility at Stanford University and leads a team in providing technical expertise, training, and resources to the campus community on accessible websites and digital solutions for people with disabilities. He is also the program lead for Accessible IT at Stanford emphasizing accessibility awareness, allyship, and accountability for institutional digital accessibility efforts. Sean currently serves as Treasurer for the non-profit Teach Access organization.
