Accessibility

Through the principle of perceivability, we want to ensure that functions and information are presented in such a way that they can be noticed by every user in the first place. The so-called two-channel principle is important to us here. This means that we make information perceivable via two different sensory channels.

Put simply, we ensure that:

  • all information that can be perceived by sight is also audible.
  • all information that can be perceived by hearing is also visible.
  • we do not convey information through colours alone, in order to compensate for colour blindness.
  • where possible, we also support/render information tactilely.

In practice, we implement this, among other things, by:

  • providing all images and graphics with alternative texts,
  • making the duration of time-based media adjustable,
  • making text sizes adjustable,
  • ensuring sufficient contrast between foreground and background, or making foreground and background sounds distinguishable,
  • or offering videos with subtitles.

Operability

So that users can interact with our IT solutions, we ensure that they can also be operated by people with disabilities.

For us, this includes, among other things:

  • keyboard operability, on which people with motor impairments or blindness in particular depend, which we guarantee.
  • time limits for individual interaction steps, which we design to be sufficient for all people.
  • we refrain from blinking and flashing in order to avoid seizures for people with epilepsy.
  • we support orientation through unambiguous and clear link texts and through various navigation paths.
  • for pointer gestures or complex gestures we offer alternatives.

Understandability

We do not underestimate the principle of understandability outside the context of IT accessibility either. We ensure that the content is easy to read and understand for the widest possible audience. This also applies when it is read aloud. We therefore use language that is as clear and simple as possible and, where necessary, provide explanations of technical terms, unusual expressions or abbreviations, so that non-specialists, people with a different mother tongue or people with cognitive impairments can also understand the content well. For us, the principle of understandability also includes the predictability of the user interface with a consistent presentation and navigation, as well as support in avoiding input errors.
