Several technological advances have contributed to providing non-visual access to information by individuals who have sight impairments. Screen readers and Braille displays, however, are not the means of choice for conveying pictorial data such as graphs, maps, and charts. This paper thus proposes the “Falcon Graph” interface which has been developed to enable visually impaired individuals to access computer-based visualisation techniques: mainly pie charts, bar charts, and line graphs. In addition to its interaction with Microsoft Excel, the interface uses the Novint Falcon as the main force feedback media to navigate the haptic virtual environment. Initial findings gathered from testing the interface are also presented.
