Computers are emerging as the most utilitarian products in the human society and therefore the interaction between humans and computers will have a very significant influence in the society. As a result, enormous amount of efforts are being made to augment the research in the domain of human computer interaction to develop more efficient and effective techniques for the purpose of reducing the barrier of humans and computers. The primary objective is to develop a conducive environment in which there is feasibility of very natural interaction between humans and computers. In order to achieve this goal, gestures play a very pivotal role and are the core area of research in this domain. Hand gesture recognition is a significant component of virtual Reality finds applications in numerous fields including video games, cinema, robotics, education, marketing, etc. Virtual reality also caters to a variety of healthcare applications involving the procedures used in surgical operations including remote surgery, augmented surgery, software emulation of the surgeries prior to actual surgeries, therapies, training in the medical education, medical data visualization and much more. A lot of tools and techniques have. Been developed to cater to the development of the such virtual environments. Gesture recognition signifies the method of keeping track of gestures of humans, to representing and converting the gestures to meaningful signals. Contact based and vision based devices are used for creating and implementing these systems of recognition effectively. The chapter begins with the introduction of hand gesture recognition and the process of carrying out hand gesture recognition. Further, the latest research which is being in carried out in the domain of hand gesture recognition is described. It is followed by the details of applications of virtual reality and hand gesture recognition in the field of healthcare. Then, various techniques which are applied in hand gesture recognition are described. Finally, the challenges in the field of hand gesture recognition have been explained. |
