Abstract

The study of mathematics is all but precluded to most blind students because of the reliance on visual notations. The Lambda System is an attempt to overcome this barrier to access through the development of a linear mathematical notation which can be manipulated by a multimodal mathematical editor. This provides access through braille, synthetic speech and a visual display. Initial results from a longitudinal study with prospective users are encouraging.
