BREVIE LOGO
An Educational Multi Media Task Force Project of the European Community


Objectives

The aim of Brevie is to demonstrate the feasability and the advantages of a radical new kind of learning environment for vocational training in production engineering and to establish a baseline for network supported cooperation between media developers, research institutions and media users (teachers and learners). Based on the com-bination of real world phenomena and virtual world simulations through a Graspable User Interface it will be possible to freely change between operations on real physical objects and their virtual counterparts. These Twin-Objects, real and corresponding virtual components, will compose a new kind of complex construction kit which prepares a new era of simulation tech-no-logy: Real and Virtual Reality. An era in which real physical parts have an adequate functional, struc-tural and behavioural description, to build from these components a composite system which again shows the correspondence between the physical and the virtual system. The new learning en-vironment allows the composition of a real system and the concrete demonstration of its behaviour by human hand operations (sensed by a scanning device), synchronously generating the control software which assures this behaviour.

The pedagogical objectives of Brevie are to improve (1) the understanding of theoretical and practical interdependencies in mechatronic systems, (2)  the competence of action in electro-pneumatics and (3) the communication about them on the level of skilled workers and engineers. The objectives will be achieved by a new intuitive User Interface which is expected to improve the learning process in production automation by supporting action oriented learning, social verbal and non-verbal communi-cation and the grasping (under-standing) of physical phenomena by really grasping them. The insight into the correspondence between concrete real and abstract virtual structures is expected to promote adequate mental models for the handling of complex technical systems.

The market for training in production automation, especially in the area of control of mechatronic systems, is characterised by a growing demand for the combination of virtual and real models, increasing safety and decreasing costs. The handling of these complex technical systems requires adequate mental models and practical experience of the hybridness or embeddedness of hard- and softwareprocesses.

The development of the Brevie learning environment for vocational training and college education will be carried out incrementally by artec, Festo Didactic, Superscape and Virtual Presence and evaluated at four application sites Escola Superior Leiria, Stockport College, Friese Poort Drachten, Schulzentrum am Holter Feld and artec. The project will start with a detailed requirements analysis, design process and implementation of a reference application "Pneumatic Circuit" from the area of control theory and practice with elements of pneumatic, electric, and Programmable Logic Control (PLC), driven by the experiences from previous multimedia projects of the partners. The installation of this application will serve as the basis for the participation of users of different educational levels (two colleges, two vocational schools) in the following process. Three components will be developed and integrated into a new complex construction kit:
 

 
A complex construction kit wich supports the close coupling of real and virtual objects, constituting a new kind of reality oriented learning environment, will be the result of the project. This prototype is not only able to support the coupling of co-located real and virtual parts, but also to couple them in a remotely and distributed (grasping through the Internet) way. A telelearning, teleworking and telecooperation system which connects users from different locations will be provided on the basis of this construction kit.

The evaluation will be carried out at the application sites by users (teachers) and end-users (learners) supported by the IWP-ETHZ on a formative and a summative way. The formative evaluation will be based on interviews by IWP-Experts during the specification and development process and will influence the design. The quantitative evaluation will take place after the installation of the completed prototypical courseware of electro-pneumatics and the new learning environment by comparing the new approach with a conventionally trained control group. After validation, the Brevie environment and its components will be set up on a commercial basis targeting the broader vocational market of industrial automation.
