Tangible 3D: Immersive 3D Modeling through Hand Gesture Interaction
Hyosun Kim, Geórgia Albuquerque, Sven Havemann, Dieter W. Fellner · 2005
This paper presents an immersive 3D modeling system that realizes a new method for creating and manipulating 3D objects using non-instrumented hand gestures. Our model representation is based on a mesh library, which is optimized not only for real-time rendering, but also accommodates for changes of both vertex positions and mesh connectivity in real time. For performing the gesture interaction, the user’s hand is marked with just four fingertipthimbles made of inexpensive material as simple as white paper. The recognized hand gestures are used to create, manipulate and deform the 3D meshes in a natural and intuitive way. With various modeling functions the modeler provides flexible modeling capabilities. The user’s viewpoints to see the modeling procedures are approximated by tracking a pair of marked polarized glasses. All modeling tasks are performed wirelessly through a camera/vision tracking method for the head and hand interaction. 1
