AN OVERVIEW OF HUMAN COMPUTER INTERACTION AND ROLE OF GESTURES

Since its emergence, Human Computer Interaction(HCI) has risen as a field of study for a powerful collaboration between user and computers. This paper exhibits an understanding of the idea of human computer collaboration. Also, we present a briefing of evolution of HCI and how gestures provide a reliable means of interaction to facilitilate an increasingly natural technique for interacting with our computers. This paper gives an overview of existing writing in regards to gesture recognition for communication between a human and computer by classifying it as per hand motions and eye motions. The usage of motions as a characteristic interface attracts the consideration for research in novel strategies. Further, study of noteworthy studies in vision based systems is additionally discussed about. The key purpose of this paper is to depict the usefulness of human computer interaction and to exhibit a rundown of progress accomplished till date which can further enhance the current gesture recognition systems for future direction.
