Tangible 3D: Immersive 3D Modeling through Hand Gesture Interaction
ثبت نشده
چکیده
Most of all interaction tasks relevant for a general three-dimensional virtual environment can be supported by 6DOF control and grab/select input. Obviously a very efficient method is direct manipulation with bare hands, like in real environment. This paper shows the possibility to perform non-trivial tasks using only a few wellknown hand gestures, so that almost no training is necessary to interact with 3D-software. For performing the gesture interaction, the user’s hand is marked with just four fingertip-thimbles made of inexpensive material as simple as white paper. Within our virtual 3D modeling scenario, the recognized hand gestures are used to select, create, manipulate and deform the 3D meshes in a spontaneous and intuitive way. 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.
