The Audio Abacus: Representing Numerical Values with Nonspeech Sound for the Visually Impaired
This paper introduces the Audio Abacus, a novel sonification application that transforms exact numerical values into sequences of non-speech tones, following the analogy of a physical abacus where each digit is represented by a distinct sound. Unlike…
