The Development of Virtual International Sign Animation Communication for the Deaf Association of Thailand

This research aimed to design 3D virtual characters by searching for identities from the Deaf Association of Thailand. It involved creating virtual international sign animation using Motion Capture technology to record international sign language movements of the hearing impaired. Additionally, facial emotions of the characters were corrected and adjusted, as facial muscle expression is considered a clearer part of sign language. The correctness of international sign language communication was inspected by international sign language experts for dissemination at the 4th International World Federation of the Deaf 2020's inauguration speech.

The evaluation results of the international sign language animation disseminated at the 4th International World Federation of the Deaf 2020 were assessed by 30 participants using a 5-point Likert scale. The findings are as follows: For the appropriateness of characters' facial beauty, the mean score was (𝑥̅ = 4.83). For body proportions, facial features, and palm sizes suitable for international sign language, the mean score was (𝑥̅ = 4.70). For characters' costume design suitable for sign language communication, the mean score was (𝑥̅ = 4.83). For the naturalness of sign language communication, the mean score was (𝑥̅ = 4.50). Regarding the clarity and correctness of international sign language communication, the mean score was (𝑥̅ = 4.17). Finally, for the clarity of characters' facial expression in communication, the mean score was (𝑥̅ = 4.50).
