Accessible presentation of information for people with visual disabilities

Abstract

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.

Notes

  1. 1.

    The Mathtalk project was incorporated into the Mathematics Access for Technology and Science project in 1996 (MATHS) [55].

  2. 2.

    An example would be raising the voice when reading an exponent.

  3. 3.

    For example, a user should be able to skip some graphic elements and receive textual descriptions for others within the same document.

  4. 4.

    Early work on this project is based on the work in the MAVIS [5, 81, 99] project and the LABRADOOR [13] project.

  6. 6.

    However, despite the popularity of haptic mice in research settings [84, 140, 197, 233, 235] as of this writing there are no haptic mice on the market for sale.

    This work identified the two procedures of grasping and molding.
