Perceivability
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. Important for us here is the so-called two-channel principle. This means that we make information perceivable through two different sensory channels.
In simple terms, we ensure that:
- all information that can be perceived visually is also audible.
- all information that can be perceived audibly is also visible.
- we do not convey information only through colors to compensate for color blindness.
- when possible, we also support/reproduce information tactilely.
In practice, we implement this among other things by:
- providing all images and graphics with alternative texts,
- making the time duration changeable for time-controlled media,
- 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 are also operable for people with disabilities.
This includes for us among other things:
- keyboard operability, on which especially people with motor impairments or blindness depend, which we ensure.
- time limits for individual interaction steps, which we design sufficiently for all people.
- we refrain from flashing and flickering to avoid seizures for people with epilepsy.
- we support orientation through clear and unambiguous 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 even outside the context of IT accessibility. We ensure that the content is well readable and understandable for the largest possible audience. And even when read aloud. Therefore, we use language that is as clear and simple as possible and provide explanations of technical terms, unusual expressions or abbreviations when necessary, so that even non-specialists, people with a different native language or cognitively impaired people can understand the content well. For us, the principle of understandability also includes the predictability of the user interface with consistent presentation and navigation as well as support in avoiding input errors.
