There are specific usability requirements that have to be met when developing dual interfaces, that is, graphical user interfaces that are adapted for blind users. These include task adequacy, dimensional trade-off, behavior equivalence, semantic loss avoidance and device independence. Consequently, the development of human-computer interfaces that are based on the task, domain, dialog, presentation, platform and user models has to be modified to take into account these requirements. This paper presents a framework that includes these requirements, allowing for the development of dual interfaces. The framework includes a set of guidelines for interface design, a toolkit for the low effort implementation of the user interface, and a programming library for the inclusion of speech and Braille in applications. A case study of the development of one such dual interface application is also presented
