Non Visual Widgets as Reusable Components

A. Bouraoui (Tunisia)


Reusable software, component based development, assistive technology, model driven engineering.


This paper exposes how to create controls that can be used by developers to implement software for visually handicapped users. The non visual controls are adapted from graphical controls (widgets) like menus, dialog boxes, edit boxes, but they use specific input/output devices and specific interaction principles. The contribution of this work in the field of assistive technology is valuable, because there are no existing tools that facilitate the creation of interfaces for the blind users, and it may considerably improve computer access for this category of users.
