Deaf people use movements and physical expressions to reveal their ideas and feelings to their world. These expressions are called ‘sign language’, and like natural languages, there are many forms of signs worldwide. Deaf use one or two hands and sometimes use other body parts like the head, lips or eyes. Their gestures are by either static or dynamic hands, and they are a bit of complicated language. Therefore, other people need to understand the meaning of each of these signs and gestures to communicate with the Deaf community successfully. Human-computer interaction is an effective tool and an excellent trend to facilitate the communication and comprehension of the different sign languages used worldwide. The research community has tried to review the most important techniques and models used in deciphering and understanding sign languages. Every new research effort is directed towards improving these ways of communication. Some proposed models dealt with isolated signs, and others focused on continuous signs. This article represents a summary of multiple comprehensive reviews that studied different literature conducted on sign language recognition. The discussion in this review focuses on the systems and approaches that only deal with static hand gesture recognition. This work aims to provide a guide for researchers and practitioners to relate their work to existing research and gain insights into what their work can contribute to the field
