Hand Gesture Interaction with a 3D Virtual Environment

Virtual Environment (VE) system offers a natural and intelligent user interface. Hand gesture recognition is more efficient and easier interaction in VE than human-computer interface (HCI) devices like keyboards and mouses. We propose a hand gesture recognition interface that generates commands to control objects directly in a game. Our novel hand gesture recognition system utilizes both Bag-of-features and Support Vector Machine (SVM) to realize user-friendly interaction between human and computers. The HCI based on hand gesture recognition interacts with objects in a 3D virtual environment. With this interface, the user can control and direct a helicopter by a set of hand gesture commands controlling the movements of the helicopter. Our system shows the hand gesture recognition interface can attain an enhanced and more intuitive and flexible interaction for the user than other HCI devices.
