Abstract

Start-up procedures are non-routine tasks in process control, which are prone to skill decay. To mitigate skill decay, job performance aids (JPA) are used. A dynamic JPA was developed for the human-computer interface, which guides the gaze of the user by visual cues. Two gaze-guiding applications (spotlight, spotlight plus integration of information) were tested in terms of their impact in supporting the start-up performance after a three-week and six-month period of non-use ( N = 46). Irrespective of the gaze-guiding format, participants with three weeks of non-use outperform participants with six months of non-use. Results show that the best indicator of skill loss is the length of the period of non-use. It is assumed that the advantage of gaze guiding plus integration of information was not shown due to the loss of interface-operating knowledge. In conclusion, gaze guiding for long periods of non-use needs to be accompanied by interface-operating knowledge.
