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.
