“…MR design review has been investigated before, e.g., by Klinker et al [19], however, the HMDs used were rather bulky and the rendering techniques employed were missing important features to integrate the virtual objects into real scenes convincingly, most important dynamic soft-shadows were missing. The ARIS Project [1] developed a MR rendering system which uses high dynamic range images (HDRIs) to capture incident lighting.…”

In mixed reality (MR) design review, the aesthetics of a virtual prototype is assessed by integrating a virtual model into a real-world environment and inspecting the interaction between the model and the environment (lighting, shadows and reflections) from different points of view. The visualization of the virtual model has to be as realistically as possible to provide a solid basis for this assessment and interactive rendering speed is mandatory to allow the designer to examine the scene from arbitrary positions. In this article we present a real-time rendering engine specifically tailored to the needs of MR visualization. The renderer utilizes pre-computed radiance transfer to calculate dynamic soft-shadows, high dynamic range images and image-based lighting to capture incident real-world lighting, approximate bidirectional texture functions to render materials with self-shadowing, and frame post-processing filters (bloom filter and an adaptive tone mapping operator). The proposed combination of rendering techniques provides a trade-off between rendering quality and required computing resources which enables high quality rendering in mobile MR scenarios. The resulting image fidelity is superior to radiosity-based techniques because glossy materials and dynamic environment lighting with soft-shadows are supported. Ray tracing-based techniques provide higher quality images than the proposed system, but they require a cluster of computers to achieve interactive frame rates which prevents these techniques from being used in mobile MR (especially outdoor) scenarios. The renderer was developed in the European research project IMPROVE (FP6-IST-2-004785) and is currently extended in the MAXIMUS project (FP7-ICT-1-217039) where hybrid rendering techniques which fuse PRT and ray tracing are developed

“…Aspects of collaboration between co-located parties have been covered by Regenbrecht et al (2004) with a focus on social components of the collaboration process in AR. Klinker et al (2002) identified visual fidelity and communication as important usability issues for AR through a system for design review and interactive collaboration. They highlighted the problem of feasibility in the visual representation within an immersive augmented display.…”

Abstract. This paper outlines the design, execution and analysis of a user evaluation experiment using Augmented Reality (AR) in an urban design studio. The aim of the experiment was to gauge the differences between two interfaces in regard to their impact on the design process. The two conditions of the experiment were a direct manipulating tangible user interface and a pen-like 3D manipulation interface. Findings include differences in perceived object presence, performance measures, perceived performance and variations in the communication patterns. These findings have implications for the integration of this technology in a praxis relevant design work flow.

“…The MagicMeeting system (Regenbrecht et al 2002) is a multi-user AR system that allows up to four colocated users to have a design zone review meeting. Fata Morgana (Klinker et al 2002) supports five different scenarios for car designers where they can rotate a car, perform an overview evaluation, focus on details, discuss with colleagues, and compare designs. Roivis (Pentenrieder et al 2007) is an AR application that supports factory design and planning between co-located users that share a view.…”

Abstract. Augmented Reality (AR) is a technology that allows users to view and interact in real time with virtual images seamlessly superimposed over the real world. AR systems can be used to create unique collaborative experiences. For example, co-located users can see shared 3D virtual objects that they interact with, or a user can annotate the live video view of a remote worker, enabling them to collaborate at a distance. The overall goal is to augment the face-to-face collaborative experience, or to enable remote people to feel that they are virtually co-located. In this special issue on collaboration in augmented reality, we begin with the visions of science fiction authors of future technologies that might significantly improve collaboration, then introduce research articles which describe progress towards these visions, finally we outline a research agenda discussing the work still to be done.
