A Comparison of Manual and Vocal Response Modes for the Control of Aircraft Subsystems
Abstract
The objective of this study was to determine how a vocal response mode compared to a manual response mode for data entry in a fighter cockpit simulator. Specifically, both vocal and manual response modes were compared in single and dual task conditions on the basis of pilot flight performance, response time, and errors while accomplishing several communication, navigation, and weapons tasks. The results indicated that the manual response mode was more effective than the vocal response mode in terms of response time data; however, the vocal response ode was more effective in terms of flying performance data. These results pointed to a trade off strategy used by the pilots as a function of their current workload. In the dual task manual condition the pilots concentrated on the manual data entry task and flying performance suffered, whereas, in the dual task vocal condition, the pilots kept their attention on the flying task and entered data while maintaining good flight control. As a results, in future fighter aircraft both manual and vocal control should be provided to the pilot for his selection This conclusion was also supported by questionnaire results in which the pilots favored the implementation of both manual and vocal control.
