To find the most efficient way to exchange information on the digital mock-up of a product, a synchronous co-located collaborative design environment with recent technologies is in needed. A new groupware of multi-view system allows multiple users to have individual visual information of a domain-specific representation of digital mock-up. In this paper, we propose a case study for the development and testing of a co-located multi-view system in collaborative virtual reality, aiming at enhancing the multidisciplinary early collaborative design. An ergonomic method of Personas is introduced to the evaluation of the tool, considering various user performance. With a multidisciplinary mug design scenario, experiments are presented, validating the benefits of the proposed system.

Various experts use domain-specific software to produce various data. This package of data is usually called Digital mock-up (DMU), as well as Building Information Model (BIM) in architectural engineering. For sharing the DMU data, many works have been done to improve the interoperability among the engineering software and among the models in domains of mechanical design and eco-design. However, the computer-human interaction (CHI) currently used in the context of CE project reviews is not optimized to enhance the interoperability among various experts of different domains. Here the CHI concerns both complex DMU visualization and multi-users interaction. Since the DMU has its multiple representations according to involved domains, therefore when various experts need to work together on the DMU they may prefer their own point-of-view on the DMU and proper manner to interact with the DMU.With the development of 3D visualization and virtual reality CHI technology, it is possible to devise more intuitive tools and methods to enhance the interoperability of collaboration among experts both in multi-view and multi-interaction for co-located synchronous collaborative design activities. In this paper, we discuss the different approaches of displaying multiple point-of-views of DMU and multiple interactions with DMU in the context of 3D visualization, virtual reality and augmented reality. A co-located collaborative environment of CHI supporting system is proposed. This collaborative environment allows the experts to see respectively the multiple point-of-view of the DMU in front of a unique display system and to interact with the DMU in using different metaphors according to their specific needs. This could be used to assist collaborative design during project review where some decision on product design solution should be made.

Then we propose the co-located multi-view system with the technology of multi-representation, multi interaction and virtual reality. A study is investigated to evaluate the contribution to the proposed multi-view system in comparing with the traditional mono-view system during a multidisciplinary collaborative task. A multi-role collaborative application is developed to test the co-located collaboration with multiple representations in virtual reality environment. This collaborative application consists of a collaborative task which simulates industrial project review using multi-representation digital mock-up (dmu). The experiment is conducted with two persons under two different collaborative chi’s conditions: two mono-view systems and single multi-view system. The difference in term of verbal communication, contribution and efficiency of collaboration during the multidisciplinary collaborative task is analyzed to compare the two conditions.

LI, Bo; MERIENNE, Frédéric; LOU, Ruding; SEGONDS, Frederic Nowadays more and more industrial design activities adopt the strategy of Concurrent Engineering (CE), which changes the way to carry out all the activities along the product’s lifecycle from sequential to parallel. Various experts of different activities produce technical data using domain-specific software. To augment the interoperability among the technical data, a Digital Mock-Up (DMU), or a Building Information Model (BIM) in architectural engineering can be used. Through an appropriate Computer–Human Interface (CHI), each expert has his/her own point-of-view (POV) of a specific representation of DMU’s technical data according to an involved domain. When multiple experts work collaboratively in the same place and at the same time, the number of CHIs is also multiplied by the number of experts. Instead of multiple CHIs, therefore, a unique CHI should be developed to support the multiview and multi-interaction collaborative works. Our contributions in this paper are (a) a concept of a CHI system with multi-view and multi-interaction of DMU for multiple users in collaborative design; (b) a state of the art of multi-view and multi-interaction metaphors; (c) an experiment to evaluate a collaborative application using multi-view CHI. The experimental results indicate that, in multi-view CHI working condition, users are more efficient than in the other two working conditions (multiple CHIs and split view CHI). Moreover, in multi-view CHI working condition, the user, who is helping the other, takes less mutual awareness of where the other collaborator works than the other two working conditions.
