A Hand-Tracking HCI Interface

Human computer interaction, or HCI for short, concerning how people interact with computers, has long been an important and popular research field. Traditionally keyboards and mice are the most commonly used devices. In order to have a more flexible interaction, this paper proposes a vision-based interface for human computer interaction based on hand contour tracking. As an articulated hand can provide more freedom, the versatility of possible interactions also increases. Our algorithm combines several existing methods and further improves them to provide a more accurate and responsive hand tracking system. In addition, we also propose a novel windows interface to facilitate human computer interaction.
