The advancement in technology has revolutionized the way of communication with computing devices. The conventional interaction technique consists of input devices such as mouse, keyboard and pointers which requires physical handling. A multimedia interaction approach provides a comfortable, touch-less, novel solution. Consequently, several approaches have been proposed as a mode of communication for the information and communication technology ICT applications. In recent years, the ubiquitous computing with conventional camera is progressing towards potential gesture based communication as a novel modality for human computer interaction HCI. Now, the gesture based technology is gaining popularity as it proves to be natural and intuitive mode of communication [1]. The target application of such hand gesture interactive system includes smart environments like training institutes, office, home, malls etc. In fact the modern work places and business environments which are equipped with dedicated conference room having computer assisted systems can be enhanced with gesture based technology. However, the gesture interface is a complex research problem as it involves image processing techniques for gesture recognition. The basic challenge in designing a gesture interface lies in dealing with various factors such as illumination, complex background, camera characteristics, and ethnicity. A typical gesture interface setup consists of computing system, camera and efficient algorithm [2]. It is required that the gesture interface should be simple, user friendly and respond in real time. Thus, the performance of interface depends on the hardware and efficient software techniques used. In present work a comprehensive study of multimedia interfaces for ICT applications is conducted. A review of various gesture recognition techniques is performed to identify optimum method for real time interaction. A preliminary study of implementing gesture interaction for computer system is done. Accordingly, a prototype is developed that recognizes hand gesture and converts it into actions to interact with various computer applications such as VLC, PPT etc.
