<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 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 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)
Overtaking maneuvers were studied in real traffic, by comparing cases where a change in the opposite traffic occurred during the overtaking maneuver i.e., appearance of an oncoming car, with cases where no change occurred during the maneuver i.e., either an already apparent oncoming car or no oncoming car. In total 45 naturally occurring cases of overtaking(More)
<b>Motivation</b> --- To identify the objects/entities that determine the ontology of the motorcyclist's visual exploration activity, when driving in urban arterials. This ontology may form the basis for modelling the motorcyclists' visual activity in urban traffic as well as shed light in their interaction with automobile drivers. <b>Research approach</b>(More)
<b>Motivation</b> -- To enrich our understanding of the factors that influence the decision to overtake against two way traffic, and this, beyond the limitations of the human visual system in making spatiotemporal estimations. Such understanding may be valuable for the design of future adaptive aid systems. <b>Research approach</b> -- An explorative(More)
