“…In their recent survey of audio presentation of diagrams, Brown et al [24] identified several design principles which are required for non-visual diagram access. These principles also apply to tactile and multimodal presentations of diagrams.…”

“…The search mechanism provides access to the explicit information in a diagram, such as the nodes or edges of a graph; however, there should also be a means of providing access to implicit features of interest within the diagram. The example used in [24] is locating and describing cycles within a simple graph. • Representational constraints.…”

Personal computers, palm top computers, media players and cell phones provide instant access to information from around the world. There are a wide variety of options available to make that information available to people with visual disabilities, so many that choosing one for use in any given context can often feel daunting to someone new to the field of accessibility. This paper reviews tools and techniques for the presentation of textual, graphic, mathematic and web documents through audio and haptic modalities to people with visual disabilities.

In this paper we discuss why access to mathematical graphs is problematic for visually impaired people. By a review of graph understanding theory and interviews with visually impaired users, we explain why current non-visual representations are unlikely to provide effective access to graphs. We propose the use of multiple views of the graph, each providing quick access to specific information as a way to improve graph usability. We then introduce a specific multiple view system to improve access to bar graphs called SoundBar which provides an additional quick audio overview of the graph. An evaluation of SoundBar revealed that additional views significantly increased accuracy and reduced time taken in a question answering task.

“…Researchers and developers have considered the design of audio interaction with similar content in other contexts*e.g. tables (Yesilada et al 2004), lists (Pitt and Edwards 2003), Cartesian graphs (Mansur et al 1985) and node-arc graphs (Brown et al 2004) have all been tackled*and their solutions can form the basis for designing interaction techniques that can be applied to dynamic Web content.…”

Presenting Web content through screen readers can be a challenging task, but this is the only means of access for many blind and visually impaired users. The difficulties are more acute when the information forms part of an interactive process, such as the increasingly common ''Web 2.0 applications''. If the process is to be completed correctly and efficiently it is vital that appropriate information is given to the user at an appropriate time. Designing a non-visual interface that achieves these aims is a nontrivial task, for which several approaches are possible. The one taken here is to use eyetracking to understand how sighted users interact with the content, and to gain insight into how they benefit from the information, then apply this understanding to design a non-visual user interface. This paper describes how this technique was applied to develop audio interfaces for two common types of interaction*auto-suggest lists and pop-up calendars. Although the resulting interfaces were quite different, one largely mirroring the visual representation and the other not, evaluations showed that the approach was effective, with both audio implementations effective and popular with participants.
