BITV 2.0 – Only one building block of accessibility
The regulation for the creation of barrier-free information technology was issued on the basis of § 12 BGG. It specifies the design guidelines of information offers of the authorities. These include internet presences, intranet appearances as well as graphical program interfaces.
The BITV aims to ensure unrestricted access to information for people with disabilities. This should lead to increased self-determination and thereby promote equal opportunities and quality of life.
The regulation highlights the following four principles that must be fulfilled by the information services of public services:
- Perceptibility - "Information and components of user interfaces should be presented in a way that users can perceive."
Example: In order to be able to perceive pictures also by blind humans, descriptive alternative texts must be deposited for the pictures. This allows screen readers to interpret the images and read them to the blind user.
- Usability - "The components of the user interfaces and the navigation must be able to be operated."
Example: Each element, such as B. Input fields must be accessible with the keyboard and can be operated.
- Comprehensibility - "The information and operation of the user interface must be understandable."
Example: Input fields should be provided with hints, so that the user can easily fill in them.
- Robustness - "Content must be robust enough to be reliably interpreted by as many user agents as possible, including assistive technology."
For example, software must be compatible with assistive technologies, such as screen readers, so that a blind user can use the software.
Each principle includes specific requirements and operations to be distinguished in priority I (must be met) and priority II (should be taken into account). The principle "robustness" has only requirements and conditions with priority I.
Many market providers who check for accessibility only test according to BITV 2.0. But this is just one component of accessibility. Due to our more than 30 years work in the field of workplace equipment of the blind and visually impaired, we have unique expertise that can not be found in laws and regulations.
