Making chalk and talk accessible

This paper investigates the development of an authoring package designed to mimic traditional "chalk and talk" delivery of content in education. It emphasizes the twin goals of making the output more accessible both for those with disabilities and for distance learners and also making the package usable by academic staff without requiring extensive training. It deals with issues arising from the capture of the material, the compromises and conflicts which are made in the satisfaction of accessibility guidelines and the implementation problems which arise. An authoring tool designed specifically for the production of accessible multimedia material is described as is preliminary work being undertaken to provide live subtitles of lectures.
