This paper reviews the technology for using hand, body and facial gestures as a means for interacting with computers and other physical devices. It discusses the rationale for gesture based control technology, methods for acquiring and processing such signals from human operators, applications of these control technologies, and anticipated future developments. Today, there is a growing interest in research and development of new human-machine interaction systems that are more natural and ergonomic for the users. The gesture recognition plays an important part of human-machine interaction systems. The focus is done in systems that are based on accelerometers, and on glove based equipments. Based on several papers, the process for different types of approach of gesture control is described. Some applications of these technologies are also presented
