Abstract : The evolution of technology and the shift in the role devoted to operators in industry, from simple task execution to complex system control, provoke a development of the literature concerning assistance to fabrication process. This thesis of psychology joins this literature. It aims at designing an assistant to fabrication process, called the virtual companion, which would both support performances and maintain or improve competences. In particular, the virtual companion would be addressed to operators in an aeronautical factory. The case study requires in line simulation of dynamic physical processes. Two fields of the literature were used: frameworks concerning interface design for dynamic situations and those concerning competences. A three-parts methodology was used: (1) activity analysis of the operators in the real factory, (2) conception and validation of a microworld, and (3) design and test of a virtual companion in the microworld. Results show that the operators of the factory use a misleading scheme during their activity. This misleading scheme is also used by random participants. Moreover, this misleading scheme has an effect on the performances of random participants trained in the microworld. Finally, the virtual companion, whose interface is design based on EID principles, does not eliminate the misleading scheme. However, the participants who did not use the misleading scheme performed better after using the virtual companion. This results leads to the conclusion that studying the operators’ use of misleading schemes seems accurate as such schemes may impair the use of interfaces designed to support their activity.
