Colors and contrasts
The texts are designed to be easy to read, using colors that contrast strongly with the background.
Colors are not the only things used to display information. We also use symbols.
Certain color combinations are avoided (such as red and green) since they can make the text difficult or impossible for some people to read. Only easy-to-distinguish colors are used.
Navigation
User guidance is simple and straightforward.
All menu items are clearly labelled and easy to find. There is sufficient space between items so that it's easy to click on the right one.
Buttons and links are large enough to be easily clicked.
Errors: If the user has entered something incorrectly, an error message is displayed. That allows the error to be easily corrected.
Fonts
A clear and easy-to-read font is used.
The text is divided up into paragraphs to improve readability.
The font size can be adjusted for better legibility.
Tactile elements
Poststations use tactile elements in key places to allow visually impaired users to operate the devices. All interactive functions have Brail inscriptions.
Interactive functions include the card reader for payments, dispenser slot for stamps and receipts, and the earphone port with volume control, and more.
Screen reader
When you plug your earphones into the Poststation audio port, screen reader mode will activate.
A brief introduction to using the screen reader and the most important touch gestures will be provided.
There are text alternatives for images, graphics, symbols and control elements that convey information.
Images that are purely decorative and contain no relevant information are hidden from the screen reader.
Forms are clearly labeled.
Errors have simple explanations.
Links and buttons are labeled.
Cashless payment is made via an external card terminal with a touchscreen. The PIN entry is announced through a small speaker, not through the headphones. The input is done via a touch-sensitive keypad. This is currently not a common method for blind users. A brief guide on how to operate the terminal is provided.
