Abstract

Remotely Operated Vehicle (ROV) operation is a prime candidate for training by simulation. In the present study, we investigate the simulation of ROV operation, especially related to search tasks, using low-cost Commercial Off The Shelf (COTS) development tools, so-called “serious games”. In particular we investigate whether the cognitive processes of search, recall and spatial awareness of the user are the same when “technical aids”, such as metal detectors are used. The findings show that there is no significant difference in a person's ability to recall location or environmental features when performing a task in the real or virtual world.

The second area of investigation focuses on comparisons between control of ROVs, in simulation and in reality. There was a clear positive significant difference in performance for those participants that had received virtual training. This validated the simulation as having the appropriate psychological fidelity required to make training effective.

Finally, the impact of high fidelity simulation on the dependency of technical aids is investigated. The findings suggest a significant increase on the dependency of using additional technical aids when the simulation fidelity was increased. There is also significant evidence to show that the increased fidelity did affect the search strategy employed.
