In this paper we present a new method for auraliza-tion of the vorticity of a streamline in a vectorj?eld. This technique involves using a composite tone formed by superimposing sine waves of various amplitudes whosefiequency and amplitude vary in such a way as to give the perception that the resulting sound increases or decreases endlessly in pitch without(More)
The potential utility of dividing the information flowing from computer to human among several sensory modalities is investigated by means of a rigorous experiment which compares the effectiveness of auditory and visual cues in the performance of a visual search task. The results indicate that a complex auditory cue can be used to replace cues traditionally(More)
We present UnWindows VI, a set of tools designed to assist low vision users of X Windows in effectively accomplishing two mundane yet critical interaction tasks: selectively magnifying areas of the screen so that the contents can be seen comfortably, and keeping track of the location of the mouse pointer. We describe our software from both the end user's(More)

This work considers databases which store music and explores how these may best be searched by providing input queries in some musical form. For the average person, humming several notes of the desired melody is the most straightforward method for(More)
