In addition, it is possible to improve the accessibility of information by configuring your computer at the browser and operating system level. Below is an overview of the basic aids.
A more comprehensive guide on the same topic is available here (in English).
Keyboard navigation
This website can only be navigated using the keyboard. Navigation is done using the Tab key. With each press, the focus moves to the next element. The currently active element is indicated by a color change and a box around it. To activate a focused link, press the Enter key on your keyboard.
The first 2 links that become active when navigating in this way are hidden from the normal user and are specially designed for keyboard navigators. These are respectively “Move to main content”, and “Accessibility”.
"Move to main content" skips the header and left pane and jumps to the main content of the page. "Accessibility" refers to the same page you are currently on.
Enhancing content
Web browsers
To enlarge the content, we recommend first using the built-in functionality of the web browser.
In all popular web browsers, you can zoom in and out by holding down the Ctrl key (Cmd key in OS X) and pressing either the + or - key at the same time. Another convenient option is to use the mouse: holding down the Ctrl key and at the same time moving the mouse scroll wheel. You can return to normal size by pressing the Ctrl and 0 keys at the same time.
Standalone programs
All major operating systems include settings to increase the content displayed on the screen.
In Windows 7, you can find a program called Magnifier if you click on the "Start" menu button at the bottom left, type Magnifier (the first few letters are enough) and press Enter. A small window will open in which everything is magnified. By default, the program tracks the position of the mouse cursor.
In Windows 10, to open it, you have to click on the button with the Windows logo on the lower left and at the same time press the plus sign (+) button on the keyboard as many times as you want to enlarge the content. To reduce the size of the content, simultaneously press the Windows logo button and the minus sign (-) button on the keyboard.
On Apple computers, to use zoom, navigate to: Apple menu > System Preferences > Accessibility (or Universal Access) > Zoom.
Browser extensions
For web browsers, there are zoomable extensions that add to the existing functionality of the web browser. For example, Zoom Page for Firefox, which allows you to enlarge both the entire page and only the text; AutoZoom for Chrome.
Using a screen reader
A screen reader is a program that tries to interpret what is displayed on the computer screen and convey it in other forms - for example, as sounds, audio commentary. In particular, it is an aid for the visually impaired.
The content presented on this website has been created according to standards that can be understood by screen readers and in such a way that any type of visual content can be reproduced in another form. For example, the images have textual descriptions, below the video is a description of what is happening in the video, the arrangement and order of the structural elements takes into account the movement of the screen reader on the screen and allows information to be consumed in a logical order.
