Def#1:
The accessibility of a product or service is it can be used by all its
intended users, taking into account their differing capabilities. A
user's ability to make inputs and perceive outputs may be impaired.
This can be either permanent or temporary and may be due to various
physical, mental or environmental conditions.
Software accessibility or other devices accessibility can be measured in following perspectives:
• All users are able to perceive and understand the controls, instructions and outputs
• All users are able to reach and manipulate the controls, inputs and outputs
• The user interface is consistent across functions, devices and repeated use
• For users who still cannot use the service, an equivalent alternative service is available
• The controls, instructions, inputs and outputs might include such
things as buttons and keys, the labels that indicate their function,
identification cards, menus and prompts, displayed information,
delivered outputs such as money or tickets, audible warning beeps and
indicator lights.
