A comparison of voice and multifunction controls: logic design is the key

The proper design of the human-computer interface is a key feature for the optimum use of advanced manned systems. In future aircraft cockpits, one of the pilot's principle tasks will be to interact with a very sophisticated computer system—an electronic crewmember. This paper discusses the experimental comparison of two communication mechanisms: voice control and multifunction keyboards. The paper also discusses the crucial role of the software logic used with these devices.
