ABSTRACT
This paper presents the design and evaluation of a hypermedia system for blind users, making use of a non-visual interface, non-speech sounds, three input devices, and a 37-node hypermedia module. The important components of an effective auditory interface are discussed, together with the design of the auditory interface to hypermedia material. The evaluation is described, which was conducted over several weeks, and used a range of complementary objective and subjective measures to assess usability, performance and user preferences. The findings from evaluations with 9 visually impaired student participants are presented. The results from this research can be applied to the design and evaluation of other non-visual hypermedia systems, such as auditory WWW browsers and digital talking books.
