Recognizing hand gestures for human computer interaction

Abstract

As there are new developments and innovation in the field of computer technology, size of electronic devices is decreasing rapidly. Thus, there is a need of new input interface for such devices. Increasingly we are recognizing the importance of human computing interaction (HCI) and in particular vision-based gesture and object recognition. Simple interfaces already exist, such as embedded keyboard, folder-keyboard and mini-keyboard. However, these interfaces need some amount of space to use and cannot be used while moving. Touch screens are a good control interface nowadays and are globally used in many applications. By applying vision technology and controlling the devices by natural hand gestures, we can reduce the work space required. In this paper, we propose a novel approach that uses a video device to control the Laptop using gestures.
