We all appreciate systems and technology devices that are well designed. Eliminating unnecessary barriers from software allows people with disabilities to gain effective access to applications at school, college, in the workplace and in society.
Types of disability
The Disability Discrimination Act 1995 (DDA), defines a disability as a physical or mental impairment that has a long-term or substantial effect on a person's ability to carry out day to day tasks. When using software this includes visual, cognitive, mobility and hearing impairments.
Access technology
Software developed for use at work, study, home or in society can usually be used by a blind or partially sighted person with access technology such as speech output or screen magnification. The configuration features of access technology today are amazing, and we are able to use some powerful techniques to make a system useable for someone without sight.
Accessibility myths
There is a common view that people who would benefit from adjustments to the 'standard' computer interface are in a minority but the research contradicts this. We are all susceptible to the effects of ageing and, while we may not need adjustments now, a time will come when we may be grateful for software accessibility initiatives.
Accessibility, usability and inclusive design
We often talk about "accessible" systems or environments, and we may want to test products for accessibility, but what does "accessibility" really mean?
