Rigas, Dimitrios and Alty, James L. (2005): The rising pitch metaphor: an empirical study. In International Journal of Human-Computer Studies, 62 (1) pp. 1-20.

This paper describes a set of experiments that investigated the use of rising pitch notes to communicate graphical information to visually impaired users. The information communicated in the experiments included coordinate locations within a 40x40 graphical grid, the navigation of an auditory cursor within the graphical grid, the communication of simple graphical shapes and their size. The five simple shapes communicated were rectangles, squares, circles, horizontal and vertical lines. Stereophony, timbre, rhythms, and short tunes were used in addition to the rising pitch metaphor to aid disambiguation. Results suggested that the rising pitch approach enabled visually impaired users to understand the graphical information communicated in the absence of any visual aid. The paper concludes with a discussion of the use of rising pitch metaphor to communicate graphical information.

Alty, James L. and Rigas, Dimitrios (2005): Exploring the use of structured musical stimuli to communicate simple diagrams: the role of context. In International Journal of Human-Computer Studies, 62 (1) pp. 21-40.

The results from previous experiments using structured musical stimuli to communicate coordinate locations within a graphical grid, navigation of an auditory cursor and simple shapes are used as a basis for further exploratory research to communicate diagrams. An experimental framework program (called AudioGraph) provided a platform for investigating musical information processing for blind users. Under this platform, simple arrangements of shapes (forming diagrams) were communicated to users using structured musical stimuli. Meaningfully arranged graphical shapes (at least for the visual sense) were communicated in the absence, and in the presence of a particular perceptual context or different perceptual contexts. The results indicated that perceptual context played an important role in the interpretation of the structured musical stimuli that communicated simple diagrams. The paper concludes with a discussion on the implications of the results, the role of context and the use of structured musical stimuli to communicate graphical information to visually impaired users.
