Punjabi Indian Sign Language Dictionary Using Synthetic Animation

Abstract

Objective: Sign language is the primary form of communication for those who are deaf or hard of hearing. Modern technology necessitates the design of a 3D video dictionary for Indian Languages (ISL). Although there are several human video sign language dictionaries available, we want to construct the Punjabi ISL dictionary utilizing computer-produced animations rather than actual people. Methods/Statistical Analysis: Sign language is different from English, Punjabi, Hindi, etc., in that it cannot be spoken or written. In Punjabi ISL, the most regularly used words are grouped and then translated to the sign language writing notation (HamNoSys—Hamburg Notation System). The HamNoSys notation is changed into Signing Gesture Markup Language (SiGML) so that a synthetic animation of the sign can be made. Findings: In terms of memory usage, uniformity, and scalability, synthetic animation is superior to human film. Synthetic animations may be altered to meet the needs of the audience, but human videos cannot. However, these computer-generated animations may lack the natural and non-manual component of the sign’s expression. Applications/Improvements: It is feasible to utilize this dictionary to construct a system that translates Punjabi phrases into Punjabi ISL.
