First, the interception strategy does not work with all software due to incompatibilities between application and access software. There is some argument, however, as to whether these natural sounds can be used to represent all user interactions. Edwards tested this representation with some modifications and extensions. These findings should be considered also. The problems for non-sighted users in accessing GUI technology are important to mainstream computing because attempts to solve these problems can result in advances which make computers more accessible to all people.
Redundancy is a critical component of human communication.
Yet there is very little redundancy built into human computer interfaces. Research in auditory interfaces for sighted users seeks to address this deficiency. The issue of technology access and adaptation for persons with disabilities will become increasingly prominent with the recent passage of the Americans with Disabilities Act. While there are professional societies which address the problems of persons with disabilities, including those of technology access, the ACM is also an appropriate forum for the reasons stated above.
