Computer software has become much more sophisticated in the last decade. The norm is now to use a graphical user interface, such as Windows, which can be accessible but is not easy to use non-visually (eg with synthetic speech output). However most operating systems now incorporate accessibility features, but many older users are unaware that these exist.
Particular problems are caused by software which bypasses the standard protocols in the operating system; this can mean that assistive devices will not operate correctly.
Cognitively impaired users can sometimes use specific applications with little difficulty once the application is launched and configured for their needs. However they often find error messages incomprehensible and then get confused as to how they can recover from the situation. Such problems can put off older users who may be less experienced in using computer systems.
