Accessing Web Based Documents through a Tree Structural Interface

In addition to the intrinsic accessibility difficulties posed by a graphical user interface for blind web users, specific usability penalties arise from the serial nature of blind adapted interfaces (speech, braille). We propose an approach to the design of a browser tailored for blind users which may mitigate some of these difficulties. We suggest this may be achieved through maximal exploitation of structural HTML mark-up to support highly dynamic and interactive user control of content rendering.
