Abstract : Direct Voice Input, a conventional keyboard and a touch-sensing display have been compared as methods of en-route data entry during a simulated ground attack sortie. It was shown that when using Direct Voice Input the pilot looked inside the cockpit less frequently and for shorter periods and, when flying at very low level, was able to control height more accurately than when using either of the tactile systems. Contrary to expectation, the total entry times for a sequence of data and the times between entry of individual instructions and digits were longer using Direct Voice Input than with either the keyboard or the touch-sensing display. This was attributed to the characteristics and performance of the isolated work recogniser used in the DVI system. A further simulator trail is planned, which will use a connected speech recogniser with a higher recognition performance. (Author)
