IMPROVE: Collaborative Design Review in Mobile Mixed Reality.
ABSTRACT In this paper we introduce an innovative application designed to make collaborative design review in the architectural and
automotive domain more effective. For this purpose we present a system architecture which combines variety of visualization
displays such as high resolution multi-tile displays, TabletPCs and head-mounted displays with innovative 2D and D Interaction
Paradigms to better support collabo rative mobile mixed reality design reviews. Our research and development is motivated
by two use scenarios: automotive and architectural design review involving real users from Page\Park architects and FIAT Elasis.
Our activities are supported by the EU IST project IMPROVE aimed at developing advanced display techniques, fostering activities
in the areas of: optical see-through HMD development using unique OLED technology, marker-less optical tracking, mixed reality
rendering, image calibration for large tiled displays, collaborative tablet-based and projection wall oriented interaction
and stereoscopic video streaming for mobile users. The paper gives an overview of the hardware and software developments within
IMPROVE and concludes with results from first user tests.

ABSTRACT: During design reviews, multiple stakeholders convene to reflect on the quality of intermediate results and to decide upon following steps. As prior research indicates, such design reviews are only partly a structured, rational process; often aspects as trust, hidden agendas or lacking commissioning skills influence this activity. Furthermore, a wide range of media is being used during these meetings, which are difficult to recollect in their context after the event. This research project attempts to improve design reviews in the domain of Industrial Design Engineering by two means: (1) by providing a specific prototyping and annotation device employing physical mockups, (2) by recording both communication between stakeholders and interaction with the prototype to produce comprehensive coverage of the review session. Based on literature and additional case studies, an analysis of the information streams is presented. Furthermore, an Interactive Augmented Prototyping solution is devised. Early verifications show that the recording resolution still requires a lot of fine-tuning, which will be the primary focus prior to a comprehensive evaluation in practice.International Journal for Interactive Design and Manufacturing (IJIDeM) 04/2009; 3(3):189-200.

ABSTRACT: In this paper, a collaborative system for product information visualization and augmentation is presented. The developed system allows the users, who can be remotely distributed, to view a product model, which is a geometric representation of the product, from different perspectives. They can choose to view design and product history, such as previous modification processes and feature information of the product independently. The product models displayed to the users are immediately updated after any design modifications have been made to the CAD model. Product features being discussed can be highlighted to draw the users’ attention. In addition, modifications can be displayed dynamically for the users to evaluate the design effect. The product history document module in the system provides a user-friendly interface for retrieving design records. After a specific record has been chosen, the related product model is displayed, and it can be aligned with the current product model for the ease of comparison and evaluation. The feature information of the product is displayed using virtual “floating” annotations linked to the related features. A user interface to enter annotations is provided, and the annotations entered by different users can be shared in real time. A cluster-based greedy algorithm is implemented to avoid overlapping annotations in the field of view.Computer-Aided Design. 01/2008;

ABSTRACT: A system was developed for the creation of urban scenarios pro-duced on large screen displays using laser pointers as input devices and supporting collaborative usage. A novel interface had to be de-veloped to support interaction with such input devices, based on the concept of gates and circular menus with a non-intrusive interface. Users can navigate on a virtual world using a set of comprehen-sive navigation modes, namely: first person, bird's eye view and examine modes, along with a multimodal flight mode controlled by speech commands and arm tracking. Simple shapes can be created and modeled using a minimalistic set of modeling tools, defining a novel modeling interface. Buildings can be instantiated from a li-brary of facade styles by drawing the desired blueprint and setting the facade height to generate unique buildings. Additional styles may be implemented by making use of a developed XML format for defining façade layout rules. Buildings and other shapes can be transformed and cloned. Objects in the scene can have notes at-tached to them to aid in reviewing sessions. An alternative building creation work flow is proposed to take advantage of this system for early prototypes and showcasing projects.11/2008;
