Abstract
A system and method for manipulating virtual objects in a virtual environment, for drawing curves and ribbons in the virtual environment, and for selecting and executing commands for creating, deleting, moving, changing, and resizing virtual objects in the virtual environment using intuitive hand gestures and motions. The system is provided with a display for displaying the virtual environment and with a video gesture recognition subsystem for identifying motions and gestures of a user's hand. The system enables the user to manipulate virtual objects, to draw free-form curves and ribbons and to invoke various command sets and commands in the virtual environment by presenting particular predefined hand gestures and/or hand movements to the video gesture recognition subsystem.
