In this article we examine earcons, which are audio messages used in the user-computer interface to provide information and feedback to the user about computer entities. (Earcons include messages and functions, as well as states and labels.) We identify some design principles that are common to both visual symbols and auditory messages, and discuss the use(More)

A large number of disparate technologies contribute to an understanding of how to design a multimedia, multimodal interface. These vary from the use of vision, gesture and sound to applications, tools for interface construction, models and metaphors, and enabling technologies, such as video disk, and image processing. The primary objective of the workshop(More)
A system for the creation of computer-generated sound patterns of two-dimensional line graphs is described. The objectives of the system are to provide the blind with a means of understanding line graphs in the holistic manner used by those with sight. A continuously varying pitch is used to represent motion in the x direction. To test the feasibility of(More)
Extensible scientific visualization tools are often offered as data analysis tools. While images may be the goal of visualization, insight is the goal of analysis. Visualization tools often fail to reflect this fact both in functionality and in their user interfaces, which typically focus on graphics and programming concepts rather than on concepts more(More)
