Sign Language Video – Accessibility Glossary

A sign language video is a form of accessible multimedia that conveys information in a national sign language such as German Sign Language (DGS). It typically features a signer displayed in a video window translating spoken or written content, making it directly accessible to deaf users.

These videos are not simply subtitles or captions, they are translations into a visual, gestural language. This distinction is critical because many deaf individuals use sign language as their first language and may not fully understand complex written texts.

Where and How They Are Used

Sign language videos are often embedded into websites, public service announcements, or digital applications. They serve various purposes, such as:

• Explaining legal rights or administrative procedures
• Providing access to educational material
• Enhancing inclusive communication in government and healthcare
• Translating essential public health or emergency updates

Technical and Design Considerations

To ensure accessibility and usability, the videos should:

• Have high contrast and clear visibility of the signer
• Be easily discoverable (e.g., sign language button on a page)
• Load quickly and support playback controls

Proper implementation of sign language videos is a WCAG (Web Content Accessibility Guidelines) recommendation and often a legal requirement in public digital services.

Sign language videos translate content into German Sign Language and are aimed at people for whom written German is not the first language. Typical uses are home pages and accessibility statements, information on procedures, or short introductions to products and services.

Good results need more than a camera: the person must have upper body, hands and face fully in the frame, the background should be plain and high-contrast, and the lighting must not cast shadows on the hands. The translation is best produced by deaf specialists or qualified interpreters who render the text not literally but by meaning in DGS.

Embed the video so that it is easy to find, for example with its own icon in the page header, and add subtitles and a transcript. Also make sure the player controls can be operated by keyboard. That way you reliably reach your target group and at the same time meet requirements from BITV and WCAG.
