The Defence and Civil Institute of Environmental Medicine (DCIEM) has been contributing to research into the application of Direct Voice Input (DVI) to military systems to facilitate their operation in demanding situations. In support of this research, the Canadian Marconi Company (CMC) was contracted by the Chief of Research And Development (CRAD) to install and demonstrate a DVI system in the National Research Council (NRC) Institute for Aerospace Research (IAR) Bell 412 helicopter. This system was to be evaluated by Canadian Forces (CF) pilots from the Department of National Defence (DND). The system was installed in the helicopter in 1996, and successful flight demonstrations were flown by five CF pilots and one NRC pilot between Oct 96 and Jan 97. NRC is currently producing a report on the results of the speech experiments with respect to recognition rates and other linguistic issues. However, no formal report was ever produced to document the human factors issues identified during those flights. CMC also acquired considerable expertise and insight on DVI technology during the development of the Bell 412 system and the conduct of the flight demonstrations, but none of that knowledge has been formelly recorded either. This report is being produced to document the human factors aspects of the DVI flight demonstrations and the operator interface design. It is intended to augment the NRC report on the speech experiments.
