Using ecological interface design to develop an auditory interface for visually impaired travellers

Abstract

This paper discusses the development of a prototype design of an auditory interface for the visually impaired based on the work domain analysis of ecological interface design. Secondary mobility devices have been developed to increase preview distances in addition to a long cane, but these have gained limited acceptance. These devices lack an easily interpreted interface. An interface design that provides the user with sufficient preview to avoid obstacles and plan a path among obstacles is presented
