Research exploring factors that affect an operator's use of automated systems has gained a great deal of attention over the years; however, it is only recently that an operator's simultaneous use of multiple automated aids has been investigated. The current study employed a target search task to examine how individuals utilize two automated aids when one of the aids fails and begins to decrease in reliability. More specifically, we were interested in investigating whether people would be able to switch from utilizing the failing aid (originally highly reliable) to the other aid (originally less reliable) when the failing aid became less reliable than the other aid. The results show that participants were able to consistently use the more reliable aid, even if this meant switching from one aid to the other. Practical implications are discussed.
