Most current interfaces rely almost entirely on vision to present information.
This is not natural and can cause sighted users to become overloaded and is a major problem for people with sight impairments. What we are doing is investigating the use of other senses for human-computer interaction, in particular hearing and touch. This page will tell you about what we are doing and will provide links to other resources. If you have any questions, comments or queries then feel free to contact me . I have been doing work with earcons since 1990 with many interesting results and have used them for many different things.
