signlanguage is a communication tool for deaf and dumb people that includes known signs or body gestures to transfer meanings. It uses shapes, directions, movements of hands, and also facial expressions. A sign not only transmits a word but also conveys a tone. Many of the deaf people are not only able to speak, but also not able to write or read a language, so developing signlanguage translation or in other words signlanguagerecognition (SLR) system can be very vital in their life. The SLR is extremely desired because of its capability to overcome the obstacles between deaf and normal people. It is one of the most important research fields in the human computer interaction studies. Hence, this paper presents an overview of the recent main research works with the vision-based SLR system, and the existing recognition techniques are discussed. Next, we focus on video-based SLR system and perform continuous SLR within video sequences.
