Conference paper (peer-reviewed)abstract
- Empirical investigation in the European aerospace industry has shown major drawbacks in the way design teams share information about the value contribution of a solution during early design stages. Across functions and organizations, design teams collaborate mainly using the contractual requirements as a basis, lacking of recording and communicating the contextual knowledge and the overall intent of product and service development projects. The paper proposes an approach that uses color-coded 3D CAD models for intra-cognitive communication of such value-related information to enhance the decision-making process in design. The paper first introduces the concept of product service systems and the benefits provided by visualization, afterwards it describes how value visualization can be implemented in a CAD 3D environment. A case study derived from the aerospace industry is presented to provide an example of application of the approach in a real industrial environment.

Multimodal conversational interaction with a humanoid robot

Conference paper (peer-reviewed)abstract
- The paper presents a multimodal conversational interaction system for the Nao humanoid robot. The system was developed at the 8th International Summer Workshop on Multimodal Interfaces, Metz, 2012. We implemented WikiTalk, an existing spoken dialogue system for open-domain conversations, on Nao. This greatly extended the robot's interaction capabilities by enabling Nao to talk about an unlimited range of topics. In addition to speech interaction, we developed a wide range of multimodal interactive behaviours by the robot, including face-tracking, nodding, communicative gesturing, proximity detection and tactile interrupts. We made video recordings of user interactions and used questionnaires to evaluate the system. We further extended the robot's capabilities by linking Nao with Kinect.

Discussing the role of the physical model in intra-cognitive communication

Conference paper (peer-reviewed)abstract
- In industry today, many different tools and methods using 3D technology are used to create virtual prototypes or products. These tools are excellent for their purpose and offer great possibilities. However, even using these tools, some things are hard to transfer and examine within them. This paper gives you two examples of cases where organic objects are used as an original and then transferred into the digital world. Physical prototypes were used in both cases and the paper explains what they added in addition to the digital 3D-models.

Enhancing intra-cognitive communication between engineering designers and operators : a case study in the laser welding industry
- 2012
-
In: Proceedings of the 3rd IEEE International Conference on Cognitive Communications. - Piscataway, NJ : IEEE Communications Society. - 9781467351874 - 9781467351867 ; , s. 493-497

Conference paper (peer-reviewed)abstract
- In manufacturing, metal parts can be joined using a laser as a welding tool, i.e. laser welding. Despite huge amount of research over the years, the process is neither sufficiently understood nor mathematically predictable. This study aims to holistically analyze the knowledge management issues occurring in laser welding. Emerging from observations and semi-structured interviews from industry and academy, the complexity and the criticalities of the process as well as the current knowledge transfers is explained and analyzed, using a knowledge lifecycle framework as a reference. Besides enhanced awareness of the limiting issues, information and knowledge visualization, e.g. knowledge maps, is identified as a key for progress in the community. The Matrix Flow Chart is suggested as an alternative descaled map of process changes.

Integration of gestures and speech in human-robot interaction
- 2012
-
In: 3rd IEEE International Conference on Cognitive Infocommunications, CogInfoCom 2012 - Proceedings. - : IEEE. - 9781467351874 ; , s. 673-678
-
Conference paper (peer-reviewed)abstract
- We present an approach to enhance the interaction abilities of the Nao humanoid robot by extending its communicative behavior with non-verbal gestures (hand and head movements, and gaze following). A set of non-verbal gestures were identified that Nao could use for enhancing its presentation and turn-management capabilities in conversational interactions. We discuss our approach for modeling and synthesizing gestures on the Nao robot. A scheme for system evaluation that compares the values of users' expectations and actual experiences has been presented. We found that open arm gestures, head movements and gaze following could significantly enhance Nao's ability to be expressive and appear lively, and to engage human users in conversational interactions.

Changes in present product design : opportunities for industrial oriented research

Conference paper (peer-reviewed)abstract
- The manufacturing industry applies approaches in early development stages, i.e. product design, that heavily relies on computer support. The concept of Knowledge Based Engineering systems could represent this approach. However an ongoing trend in manufacturing industry to increase the service contents in their offerings is commonly captured beneath the umbrella term Product-Service Systems (PSS). The paper discusses conceptual examples for changes in product design caused by this increased PSS focus. The examples given are brief descriptions of different demonstrators developed in research projects focusing on PSS and product development in early phases. Examples include a discussion how companies shift from single company to becoming inter-organizational partners, how intangible knowledge, and information in the design process can be made tangible and how companies and engineers shift focus from knowledge transfer to sharing experiences
