Human-Computer Interaction System Using 2D and 3D Hand Gestures

Hand gesture interaction has been the trending technology for human-computer interaction (HCI). Frequently a number of research works are carried out in this area to expedite and contrive interaction with computers. In this paper, we propose a real-time human-computer interaction system (HCI) using two different hand gestures - hand pointing and clenched fist gesture. We propose a single camera hand gesture estimation algorithm for hand gesture tracking in 2D space from a distance and are mapped to the screen coordinates. Moreover, we also propose orthogonal cameras to estimate hand gestures in 3D space from a distance and is mapped to the screen coordinates.
