Kiosks (or self-service machines) that are accessible:
- in terms of their location allowing users to find and use the machine, e.g. not sited at the top of a flight of stairs or behind a column,
- in terms of their interaction style, e.g. content has understandable language and graphics; the task and task flow understandable; feedback is meaningful to the user; and tolerance for human error, etc.
- in terms of their interface features, e.g. screens where display is visible whether a person is short or tall; alternatives to touch screens for people who cannot use them; interface components, such as knobs, levers, slots, scanners, card readers, etc. easily distinguishable using visual, tactile and audio clues; etc.
These machines are commonly targeted at the public and designed for independent use in unmanned service / product delivery situations. As convergence between different types of internet enabled devices continues, many kiosks may act as part of the delivery chain for a series of services/products. Accessibility issues must be taken into account if these services are to be used people of different abilities.
