When You Can't Read It, Listen to It! An Audio-Visual Interface for Book Reading

摘要

This paper presents a prototype of a mobile Digital Talking Book player, which, by combining visual and non-visual means of interaction, strives to achieve universal accessibility. Details on the non-visual aspects of the interaction, both input and output, are provided. To assess the validity of the proposed solutions, an experiment evaluates the non-visual operation of the prototype. Results show users can complete the same tasks with visual and non-visual interaction. However, some limitations are identified, and the observations prompt a discussion on how the use of multimodal interfaces can improve their accessibility and usability.
