A Review For Different Sign Language Recognition Systems

The fundamental aspects of communication that take place between human beings are exemplified by human language. For people who are deaf or hard of hearing, sign language is the primary mode of communication because the spoken language is inaccessible to those who are hard of hearing. As a result, many people are disabled because of hearing loss. The understanding of sign languages is a particular area of research interest. This study provides an overview and review of hand signals, gestures, and the most important methods utilised to recognise sign languages. The methods for understanding Sign Language are shown and explained. For each method, the accuracy is given. Many researchers have presented their research based on the main categories of these techniques. There are advantages and downsides, or limits associated with each technique. This study should be used as a guide to choose the best model to implement and as a road map for future research. This will help us improve the accuracy of future models and give the sign language community a better way to study how to make a fully video-based translator.
