Abstract

The International Web for All Conference (W4A) began in 2004 as a workshop to make the World Wide Web accessible for people with disabilities. Over the years the workshop has grown into the top conference for web accessibility research, attracting a diverse crowd from academia, industry, government, and nonprofits. W4A has become the venue for scientists, students, and practitioners from around the world to showcase their latest research, widen their perspectives through discussions with peers, and establish future research agendas.
