Sign-language media are
media based on a media system for
sign languages.
Interfaces in sign-language media are built on the complex grammar structure of sign languages. Generally media are built for
oral languages or
written languages, and are often not compatible with sign languages.
Sign-language media have specific characteristics:
Sound is absent, or on very low frequencies (bass).
Sign language can be shown in
movie theaters via a
second screen mounted on the chair, playing a Sign Language Video track synchronized with the film.[6][7]
^a Sign-language names reflect the region of origin. Natural sign languages are not related to the spoken language used in the same region. For example, French Sign Language originated in France, but is not related to French. Conversely,
ASL and
BSL both originated in English-speaking countries but are not related to each other; ASL however is related to
French Sign Language.
^b Denotes the number (if known) of languages within the family. No further information is given on these languages.
