With increasing influence of globalisation and the importance of accessibility legalisation it is essential that the deaf-blind, especially deaf-blind tertiary students, can make effective use of computers for using the Web, word-processing and email for example. Conventional text to speech translation may not be effective if the student also has hearing difficulties. The authors have developed a system that can replace conventional textual characters with patterns that are matched to a visually disabled person's visual recognition capacity. A timed presentation of a sequence of such patterns can represent a word. Consecutive sequences of such patterns can represent a sentence or a paragraph. This paper includes results of experiments performed using this system via a specially developed program Dynamic Pattern System (DPS) that was designed as a test bed for such investigations. This paper also considers areas requiring further investigation.
