Auditory Scrollbar

A non-speech audio cue that conveys a user's position within a list or menu, functioning as an auditory analogue to a visual scrollbar. Auditory scrollbars use variations in pitch, tone patterns, or grouped sounds to communicate contextual information such as how many items are in the menu, where the user is currently located, and how far they are from the beginning or end. Research has identified several design approaches including single-tone (pitch maps to position), double-tone (adds a boundary reference tone), alphabetical grouping (pitch changes at letter boundaries), and proportional grouping (pitch changes every fixed number of items), with proportional grouping showing the best accuracy for menu size estimation.
