C. R. Dikovita, D. P. Abeysooriya · 2013
Human Computer Interaction (HCI) is one of the major disciplines in the field of computing which defines the way people interact with machines. HCI is a combination of computer vi science, behavioral science, design and several other areas which determines the best and optimized ways to interact with computers. The way people interact with machines changed dramatically after the 21stcentury due to the advancements of the computing devices. Computers became more portable and embedded to the environment with the improvement of processing power and miniaturization of devices. New concepts such as ubiquitous computing are also emerged with these advancements of technology. Traditional HCI concepts were failed to meet the requirements of the emerging technologies since most of these new concepts requires natural interactions rather using tangible devices. This paper present a computer vision based interactive surface application for human computer interaction which enable users to perform QWERTY keyboard and mouse interactions on a flat surface. Primarily, this research addresses the existing issues related to gesture based interactive interfaces by presenting a novel approach to perform interactions without stereoscopic vision and wearable markers. The proposing approach present a system (V-Touch) based on Haar-like features with single camera and a laser projection module that allows users to perform traditional keyboard and mouse interactions naturally using low cost hardware setup.
