Investigating user preferences in utilizing a 2D paper or 3D sketch based interface for creating 3D virtual models
Computer modelling of 2D drawings is becoming increasingly popular in modern design as can be witnessed in the shift of modern computer modelling applications from software requiring specialised training to ones targeted for the general consumer market. Despite this, traditional sketching is still prevalent in design, particularly so in the early design stages. Thus, research trends in computer-aided modelling focus on the the development of sketch based interfaces that are as natural as possible. In this report, we present a hybrid sketch based interface which allows the user to make draw sketches using offline as well as online sketching modalities, displaying the 3D models in an immersive setup,
thus linking the object interaction possible through immersive modelling to the flexibility allowed by paper-based sketching. The interface was evaluated in a user study which shows that such a hybrid system can be considered as having pragmatic and hedonic value.peer-reviewe
Investigating user response to a hybrid sketch based interface for creating 3D virtual models in an immersive environment
This research was done in collaboration with the Fraunhofer Institute for Production Systems and Design Technology Berlin. It was supported by VISIONAIR, a project funded by the European Commission under grant agreement 262044.Computer modelling of 2D drawings is becoming increasingly popular in modern design as can be witnessed in the shift of modern computer modelling applications from software requiring specialised training to ones targeted for the general consumer market.

ARTEFACTS: How do we want to deal with the future of our one and only planet?
The European Commissionâs Science and Knowledge Service, the Joint Research Centre (JRC), decided to try working hand-in-hand with leading European science centres and museums.
Behind this decision was the idea that the JRC could better support EU Institutions in engaging with the European public. The fact that European Union policies are firmly based on scientific evidence is a strong message which the JRC is uniquely able to illustrate. Such a collaboration would not only provide a platform to explain the benefits of EU policies to our daily lives but also provide an opportunity for European citizens to engage by taking a more active part in the EU policy making process for the future.
A PILOT PROGRAMME
To test the idea, the JRC launched an experimental programme to work with science museums: a perfect partner for three compelling reasons. Firstly, they attract a large and growing number of visitors. Leading science museums in Europe have typically 500 000 visitors per year. Furthermore, they are based in large European cities and attract local visitors as well as tourists from across Europe and beyond.
The second reason for working with museums is that they have mastered the art of how to communicate key elements of sophisticated arguments across to the public and making complex topics of public interest readily accessible. That is a high-value added skill and a crucial part of the valorisation of public-funded research, never to be underestimated.
Finally museums are, at present, undergoing something of a renaissance. Museums today are vibrant environments offering new techniques and technologies to both inform and entertain, and attract visitors of all demographics.JRC.H.2-Knowledge Management Methodologies, Communities and Disseminatio
Teilprojekt TP 1 - Information im PLM-Prozess
Kap. 3 betrachtet die Forschungsarbeiten zur Integration von Informationen aus dem Produktlebenszyklus in virtuellen Modellen. Der Schwerpunkt liegt dabei auf schrittweise strukturierten HandlungsablĂ€ufen, wie sie typisch fĂŒr Montage-, Demontage und bestimmte Bedienhandlungen sind. In den Arbeitspaketen wird untersucht, wie ArbeitsplĂ€ne aus Product-Lifecycle-Management-Systemen fĂŒr AblĂ€ufe in virtuellen Modellen verwendet werden können. Weiterhin werden AnsĂ€tze zur Extraktion von HandlungsablĂ€ufen aus kamerabasierten Daten und semantischen Modellen untersucht
ModelTracer: User-friendly traceability for the development of mechatronic products
The development of complex mechatronic systems demands an integration of models throughout the virtual product development process. Systems engineering is an approach for enabling the development of successful interdisciplinary products. Traceability, one of the most important aspects of systems engineering, is a method for explicit documentation of logical relationships between development artifacts. In this paper we present a prototype traceability tool, ModelTracer, which aims to reduce the cognitive effort for the creation and maintenance of traceability models in systems engineering
Erlebbarkeit von Anlagenkomponenten im Kontext Virtuelle Inbetriebnahme in virtuellen Umgebungen
Aus der Einleitung
"Der Einsatz von Virtual Reality (VR) Methoden in der Fabrikplanung und Absicherung ist bei groĂen produzierenden Unternehmen heute in allen Phasen des Produktentwicklungsprozesses (PEP) âState of the Artâ (Runde 2012). Virtual Reality ermöglicht die frĂŒhzeitige Visualisierung eines Entwicklungsstands in OriginalgröĂe. Dadurch lassen sich Design- oder KonzeptentwĂŒrfe visualisieren, frĂŒhzeitig Fehler erkennen und Absicherungen hinsichtlich Ergonomie, oder Ein- und Ausbauuntersuchung durchfĂŒhren (Rademacher, 2014). Diese Absicherungen, insbesondere die PrĂŒfung von Produktionsanlagen wird heute vor allem mit statische Modellen durchgefĂŒhrt (WestkĂ€mper & Runde 2006).
Weiterhin resultiert die zunehmende Vernetzung und Intelligenz von Produktionsanlagen im Kontext von Industrie 4.0 in hochkomplexen Anlagensteuerungen. Zur frĂŒhzeitigen ĂberprĂŒfung der Datenquellen bzw. Planungsdaten fĂŒr die reale Anlage hinsichtlich ihrer Korrektheit, VollstĂ€ndigkeit und Konsistenz bereits wĂ€hrend der Entwicklung werden daher zunehmend auch Techniken der funktionellen Virtualisierung eingesetzt. ...
Ressourcenoptimiertes Produktdesign
Die BerĂŒcksichtigung von Effizienz beginnt bereits in der Produktentwicklung. Hier werden die Weichen fĂŒr den Ressourcenverbrauch eines Produkts in allen nachfolgenden Lebenszylusphasen gestellt. Zur verbesserten Nutzung dieses Potenzials wurde eine Methodik entwickelt, die den Ingenieur dazu befĂ€higt, bereits in den frĂŒhen Phasen der Produktentstehung den verfĂŒgbaren Lösungsraum zu identifizieren und daraus MaĂnahmen fĂŒr die weitere Entwicklung abzuleiten
