Persistent audio cues in auditory display interfaces : menu navigation performance and preference comparison with non- persistent cues

This study investigates auditory display (audio only) menu interfaces and navigational cues. In an experiment using a prototype auditory display menu interface, differences in task completion time, the number of keystrokes used and preferences between navigational cues that were either short, short repeated or persistent. The navigational cues were based on earcon inspired design and were either persistent, short or repeated short navigational cues. The results of the experiment showed no support for any of the cues giving better performance results than any the other. The gathered data did however show how the subjects made significant improvements in completion time and keystroke count after 10 performance tasks.Validerat; 20101217 (root
