In this paper we present a new framework in Augmented Reality context for rapid evaluation of prototypes before manufacture. The design of such prototypes is a time consuming process, leading to the need of previous evaluation in realistic interactive environments. We have extended the definition of modelling object geometry with modelling object behaviour being able to evaluate them in a mixed environment. Such enhancements allow the development of tools and methods to test object behaviour, and perform interactions between real virtual humans and complex real and virtual objects. We propose a framework for testing the design of objects in an augmented reality context, where a virtual human is able to perform evaluation tests with an object composed of real and virtual components. In this paper our framework is described and a case study is presented.

“…Movie companies have successfully produced films like Jurassic Park, The Mask, or Titanic with digital creatures generated in a non real-time context. Similarly, in earlier work [14], we have developed an Augmented Reality system that allows virtual humans to perform script driven actions. First, color images are acquired with a single static camera.…”

“…To achieve our goal, we have augmented our earlier system [14] by developing and integrating many distinct technologies that originate from the fields of Computer Graphics and Computer Vision. In the remainder of the paper we first introduce the model-based tracking algorithm we have developed to follow the checkers board and allow camera motion.…”

Abstract. For some years, we have been able to integrate virtual humans into virtual environments. As the demand for Augmented Reality systems grows, so will the need for these synthetic humans to coexist and interact with humans who live in the real world. In this paper, we use the example of a checkers game between a real and a virtual human to demonstrate the integration of techniques required to achieve a realistic-looking interaction in real-time. We do not use cumbersome devices such as a magnetic motion capture system. Instead, we rely on purely image-based techniques to address the registration issue, when the camera or the objects move, and to drive the virtual human's behavior.
