UNLABELLED The present paper is a commentary on the recently published IEA strategy for human factors/ergonomics (Dul, J., et al. (2012), A strategy for human factors/ergonomics: developing the discipline and profession. Ergonomics, 55(4), 377-395). Two main issues that demand attention are: (i) the way others understand our profession and discipline, and(More)
The aim of the present paper is to contribute to the debate in the cognitive ergonomics community as for the adequacy of different approaches for the analysis of socio-technical systems in view of designing artifacts facilitating human work. Using a taxonomy of sociotechnical systems as frame of reference, the theoretical origins and the main application(More)
The present paper deals with a teaching method aiming at overcoming the difficulties of students for conceptual or abstract thinking within a course of User Centred Design. Following the hermeneutic approach a series of small in class exercises have been planned. In those exercises students are urged to brainstorm from early on with all levels of solution(More)
<b>Motivation</b> -- To examine if cognitive task analysis of expert machinists can be effective in developing a virtual reality based training system for CNC tool offsetting. <b>Research approach</b> -- A cognitive task analysis of expert machinists was conducted which informed the development of a VR training system for CNC tool offsetting. Subsequently(More)
The importance of the scenarios in the user-centered design process of low complexity interactive systems is well documented in various academic and professional articles. The aim of this study is to reveal the undocumented properties that distinguish useful (rich) scenarios from uninteresting (poor) ones. Two student projects, involving scenario writing,(More)
Current models of driving behavior and designs of driver support systems are not taking adequately into account the interactions between drivers. Although a driver's intended maneuver may not be physically possible at a specific time point, it may still be safely executed if the driver's intention is successfully communicated to and interpreted by another(More)
The present research deals with aircraft maintenance technicians (AMTs) situated decision-making in a commercial aircraft maintenance department. The aim is twofold: first, to study how AMTs through their situated decisions experience inconsistencies between diverse organizational imperatives and pragmatic constraints and second, to identify persistent(More)
The present communication deals with the methodology of the ergonomics field intervention process. It proposes an operationalized version of work analysis in terms of contradictions. The aim is to demonstrate that such a dialectic tool and method of representation may assist the ergonomist to frame the essence of a work activity in practical terms, swiftly(More)
