Accessibility of Web Interfaces

• Design - Representation at Task Abstraction Level
  not low level implementation level
• Implementation - Adaptive Navigation Support,
  Context Information wrt current location,

  does not mean equal quality
• Communication between interface information
  gatherers, refiners, and implementers.

Web IDEs In Relation to Accessible Interface
Portion

• Is facility there?
• If not, how can we include it.

• Bottom line Effectiveness of results will
  depend upon communication with Web IDE Vendors
