A REVIEW ON HUMAN COMPUTER INTERFACING METHODS

Abstract

Due to the recent advent of high powered processors which have made high end computations faster and easier, there has been an increasing focus on research areas of less cumbersome but high resource utilizing techniques for proper human machine interaction. One of these techniques is Gesture Recognition. Although still in its infancy, gesture recognition and control techniques possess the power to render input devices even as high end as touch-screens, obsolete. Pickering in his dissertation on Human Computer Interface (Henceforth, referred to as HCI), entitled “The search for a safer driver interface: a review of gesture recognition Human Machine Interface†(IEEE Computing and Control Engineering, 2005, pp. 34-40) said that initially touch-based technologies in the HCI field would become more popular than the rigid models of everyday use but eventually gesture based technologies would outlast them. With the progress of technology and the high resource providing machines that are being used today, we are slowly but surely heading towards this phase and gesture recognition can indeed be said to be the future of Human Computer interaction. The ability to trace a body part such as a hand in its trajectory of motion through space in a finite amount of time and to associate a meaningful gesture to this motion is part of an intelligent system design and an essential step in this new generation technology of human computer interaction taking it to a level almost mimicking natural human to human communication.
