| |
| <p>Here is a list of the different kinds of disabilities and what we can |
| do to assist people that have such disabilities: |
| |
| <ul> <li><b>Low Vision</b><br> |
| <ul> |
| <li>Support larger fonts and graphics (icons) or a |
| screen magnifier.</li> |
| <li>Use clearer fonts, i.e. provide the ability to replace for instance |
| a handwriting font by Helvetica.</li> |
| <li>Enlarge contrast between foreground and background.</li> |
| <li>Remove or avoid distracting background patterns/images.</li> |
| </ul> |
| </li> |
| <li><b>Color Blindness</b><br> |
| Do not use color as the only way to express information. |
| </li> |
| <li><b>Blindness</b><br> |
| To assist blind people in accessing OpenOffice.org we have to provide |
| alternatives to the graphical user interface. These can be |
| <ul> |
| <li>Speech output uses speech synthesis to give a textual |
| representation of everything visible on the screen.</li> |
| <li>Braille display</li> |
| </ul> |
| </li> |
| <li><b>Hard of Hearing / Deafness</b><br> |
| <ul> |
| <li>Closed captioning for providing textual representation of |
| spoken information.</li> |
| <li>Visible representation of audio signals.</li> |
| </ul> |
| </li> |
| <li><b>Mobility Impairments</b><br> |
| 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: |
| <ul> |
| <li>Alternative pointing devices like foot operated mice or eye |
| trackers.</li> |
| <li>On screen keyboard that is operated with the mouse or |
| alternative pointing device.</li> |
| <li>Speech recognition.</li> |
| <li>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.</li> |
| </ul> |
| </li> |
| |
| <li><b>Cognitive Impairments or Learning Disabilities</b><br> |
| Make the (G)UI clear and easy to understand. Provide help files |
| and documentation (training?). |
| </li> |
| <li><b>Seizure Disorders</b><br> |
| Make flashing, rotating, or moving displays adjustable or provide |
| a switch to disable them. |
| </li> |
| </ul> |
