Interest in accessing the Web from small, mobile devices, such as cell phones, is increasing rapidly. The challenge of delivering content to such devices is similar in many ways to the challenge of delivering it to users with disabilities. There is a real synergy between these use cases which offers the hope that solutions applicable to one will also be applicable to the other. This presentation will examine the ways in which recent work in standards, being driven by the need to support mobile Web users, may also help to improve accessibility.
