Disabilities and Assistive Technology
Here is a list of the different kinds of disabilities and what we can do to assist people that have such disabilities:
- Low Vision
- Support larger fonts and graphics (icons) or a screen magnifier.
- Use clearer fonts, i.e. provide the ability to replace for instance a handwriting font by Helvetica.
- Enlarge contrast between foreground and background.
- Remove or avoid distracting background patterns/images.
- Color Blindness
Do not use color as the only way to express information. - Blindness
To assist blind people in accessing OpenOffice.org we have to provide alternatives to the graphical user interface. These can be- Speech output uses speech synthesis to give a textual representation of everything visible on the screen.
- Braille display
- Hard of Hearing / Deafness
- Closed captioning for providing textual representation of spoken information.
- Visible representation of audio signals.
- Mobility Impairments
Caused by diseases like Parkin-son's disease or multiple sclerosis or physical injuries resulting loss of limbs there is a wide variety of mobility impairments. People can be assisted by:- Alternative pointing devices like foot operated mice or eye trackers.
- On screen keyboard that is operated with the mouse or alternative pointing device.
- Speech recognition.
- Sticky keys provide functionality similar to shift locking for keys like control and alternate. This enables the user to operate the keyboard with a single finger.
- Cognitive Impairments or Learning Disabilities
Make the (G)UI clear and easy to understand. Provide help files and documentation (training?). - Seizure Disorders
Make flashing, rotating, or moving displays adjustable or provide a switch to disable them.
