Sign Language Video

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.
