Evaluating the effectiveness of a priori information on process measures in a virtual reality inspection task
Abstract: Due to the nature of
the complexity of the aircraft maintenance industry, much emphasis has been
placed on improving aircraft inspection performance. One proven technique for
improving inspection performance is the use of training. Several strategies
have been implemented for training, one of which is giving feedforward
information. The use of a priori (feedforward) information is known to
positively affect inspection performance (Ernst and Yovits, 1972; Long and
Rourke, 1989; McKernan, 1989; Gramopadhye et al., 1997). This information can consist of knowledge
about defect characteristics (types, severity/criticality, and location) and
the probability of occurrence. Although several studies have been conducted
that demonstrate the usefulness of feedforward as a training strategy, there
are certain research issues that need to be addressed. This study evaluates the
effects of feedforward information on process measures in a simulated
3-dimensional environment (aircraft cargo bay) by the use of virtual reality.
