A framework for rapid evaluation of prototypes with augmented reality

Abstract

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.

1:1 Spatially Augmented Reality Design Environment

“…Augmented Reality (AR): To integrate the virtual and physical objects to take advantage of both sides, the notion of AR is proposed. Many researches such as (Balcisoy, Kallmann et al, 2000;Benford, physical environment. This creates a possibility to implement a portable immersive display system for our research.…”

Rapid Prototyping of Mixed Reality Applications That Entertain and Inform

“…It shares the idea of using a powerful scripting language, however it does not feature a high level library similar to i4D. Balicisoy et al presented a framework for the prototyping and evaluation of technical prototypes with augmented reality [7]. This approach focuses on the interaction of virtual humans with technical devices by extending 3D CAD models by additional object behavior that can be evaluated in an AR simulation running on SGI workstations.…”

Modeling Behaviors of Interactive Objects for Real-Time Virtual Environments

“…Some times objects have simple geometry but a lot of semantic information, and some times objects simply don't offer interaction, and SOMOD is used, for instance, to define relative positions around the object for collision avoidance. Some examples of interactive applications built using smart objects are: urban environment simulations [33], object prototyping with augmented reality [34], and behavioral animation of virtual actors [28]. Figure 13 shows a typical working session and figure 14 shows some snapshots of different object interactions during the simulation of an interactive computer room.…”
