Abstract
The integration of voice into a complex interface like that between a pilot and an aircraft is not trivial. In this paper, we try to address some of the factors affecting the use and integration of voice in human-machine interfaces. We describe general principles for merging different kinds of human-machine interaction, and apply them to voice interaction in the cockpit. We do this despite published opinion that psychological principles cannot be applied in the design of human-computer interaction (e.g., Landauer, 1991). The theory of Layered Protocols (LP) is introduced in context of the more general Perceptual Control Theory of behaviour (PCT). LP theory provides a model for describing interaction between complex partners based on a layered structure of protocols that differ in levels of abstraction. The proper use of feedback is fundamental to both LP and PCT. Voice interaction is useful mainly for the control of tasks requiring discrete information. Failure of voice recognition systems is often caused by inappropriate feedback. Proving feedback and forcing correction word by word may increase the mental load on a user, often leading to instability in the interation. Such inefficient, and often frsutrating, use of voice interaction can often be overcome through the use of feedback at higher, more abstract, layers of interaction. TRUNdATED
