Abstract
In this paper we describe a prototype system for directing a computer generated
scene for film planning. The system is based upon the concepts of the Intuitive
Interface, an environment in which the user interacts in front of a projection
screen, and where interaction in physical space and pointing gestures are used
to direct the scene. The environment demands certain requirements of the interaction
paradigms that cannot be converted directly from menu-based systems. We present
some new concepts using real space that cannot be found in traditional desktop
metaphors. For the pointing gesture we describe a simple algorithm based on
tracking colored regions and inverse kinematics using a simple model of the
human arm. Finally, we will discuss some results from an empirical study with
film directors using the prototype.
