- Be careful when using icons as stand-alone action button or meaningful user interface element. Only icons like save, add, delete, close, search and email can be used as stand-alone icon since they are well-known and users can interpret them without accompanying textual label. For less known icons, provide always the textual label next to the icon. When in doubt, use always the textual label together with the icon.
- Don’t use color colour as the only indication to express a meaning of an interface element. Color Colour can’t always be interpreted in an unambiguous way. Provide always an accompanying textual label when color colour is used.
- Terminology and vocabulary in your application should be defined from the user point-of-view, and not company-or product point-of-view. Use a comprehensive and easy language style; using short and clear messages adapted to your uses.
- Check recommendations on wablieft.be concerning plain, understandable language.
- Any clinical or technical terms that are being used in the application should be explained clearly to the user, either within the content of the application or via a glossary. Labels in navigation or on buttons (call to actions) should express clearly what the user could expect or will do.
