Hand gesture recognition has become one of the key techniques of human-computer
interaction (HCI). Many researchers are devoted in this field. In this paper, firstly the history
of hand gesture recognition is discussed and the technical difficulties are also enumerated.
Then, we analyze the definition of hand gesture and introduce the basic principle of it. The
approaches for hand gesture recognition, such as vision-based, glove-based and depth-
based, are contrasted briefly in this paper. But the former two methods are too simple and …

The interaction between human and computer is becoming stronger day by day. Gesture
recognition plays an effective role against the issues of different applications. This consists
of various aided tools and gesture detection and classification algorithms and techniques.
This paper introduces the main stages for constructing hand gesture classification system
and investigates various studies that utilized different algorithms and techniques. Gesture
recognition system challenges that hinder the performance of any recognition system related …
