Automated Annotation Assistance for Pidgin Sign Japanese in Sign Language Recognition

Gibran Benitez-Garcia;Nobuko Kato;Yuhki Shiraishi;Hiroki Takahashi

2024 International Conference on Cyberworlds (CW)

Year: 2024 | Conference Paper |

HTML

Japanese Sign Language (JSL) and Manually Coded Japanese (MCJ) are the two main forms of sign language used in Japan. The former differs significantly from spoken Japanese, while the latter closely aligns with spoken syntax. Pidgin Sign Japanese (PSJ) is an intermediate form that heavily relies on nonmanual signals such as facial expressions and head movements for grammatical nuances. Current sign...Show More
