Blindness
| Issues | Solutions |
|---|---|
| The images, photos, graphics can not be seen. |
Provide text alternatives for the attribute alt and if necessary, longer and more detailed descriptions (either on the same page or via a link to another page). |
| Users often listen to the web page. | Allow users to switch the navigation menus, long lists, drawings ASCII or other content that may be difficult or unnecessary to listen. |
| Users often jump from link to link using the Tab key. | Make explicit links out of context (links "Click here" are problematic). |
| Users generally do not use a mouse. |
Do not write scripts that require only the use of a mouse.
Provide alternatives for the keyboard (use onFocus instead of onMouseover ). |
| It can be difficult for users to know where they are when they listen to the contents of table cells. |
Provide in-row and column (tag th ).
Make it understandable tables listening - especially those who have merged cells - when they are read line by line from left to right. |
| Complex tables and graphs which usually displayed visually are not usable. | Provide summaries and / or text alternatives, if possible on the same page or to link to another page as an alternative. |
| The frames can not be "seen" as a whole. they must be visited independently, which can lead to disorient the user. | Do not use frames unless you are forced. If you use frames, provide titles to frames that inform the user of their natures (examples: "Menu Navigation", "Main content"). |
| The colors can not be interpreted. | Do not use only color to convey information. |
| Users expect that all relationships have a destination. |
Do not write scripts in links that do not have real destinations (example: href="javascript: function(cela)" ). |
| Screen readers read Web content in the literal order of appearance in the code. | Check the CSS and layout tables are read correctly visually complex and in the code. |
| Users can not see the videos. | Provide an audio description of the events of videos that can not be understood only through dialogues (it takes a narrator who describes the actions in the videos for which there is no dialogue). |
Daltonism
| Issues | Solutions |
|---|---|
| Similar contrasts of colors are often indistinguishable (reds and wersts example). |
|
Low Vision
| Issues | Solutions |
|---|---|
| Users often use software screen magnifiers. | To reduce the area with horizontal scrolling, use relative units rather than absolute values (eg, use of percentages for the widths of tables instead of pixels). |
| The texts in the images can not enlarge without the use of specific software and appear pixilated when they are enlarged. |
|
| Users may want to set their own fonts and colors of wallpaper. | Allow users to make their own settings using text wherever possible in text and not images. |
Hearing impairment
| Issues | Solutions |
|---|---|
| The sound is unusable. |
|
Motor disability
| Issues | Solutions |
|---|---|
| Users may not be able to use the mouse. |
|
| Users may not properly control the mouse or keyboard. | Make sure your pages allow errors (eg, "Are you sure you want to delete this file"). Do not create small links or moving parts. |
| Users may be tired of using assistive technologies. | Provide a method for passing long lists of links or content along. |
| Users can use software control by voice. | Software control by voice can replicate mouse movements, but not as effectively as they can replicate the functionality of the keyboard. Therefore, make sure that all features are available from the keyboard. |
| Users may tire using assistive technologies. | Provide a method for passing lists of links or content too long. |
Cognitive impairment
| Issues | Solutions |
|---|---|
| Users can be hampered by complex layouts and navigation systems inconsistents through the website. |
|
| Users may have difficulty concentrating or understanding the long paragraphs of text. |
|
| One method of presenting web content may be insufficient. |
