This paper provides a brief survey of various research works carried out so far in the field of sign language technology.
: Sign language is used by speech impaired people for communication but normal people do not know sign language which causes a communication gap between them. This gap can be filled using today’s advanced technologies. Technologies such as image processing and machine learning can be used to build a system which converts sign language to text or speech. These systems can be of great help to dumb people as they can easily communicate with anyone using such system.
