On the Issue of Error in Man-Machine Communication

Avoiding errors in the cource of man-machine interaction is one of the essential tasks of an intelligent man-machine interface. There can be more than a couple of categories as the causes of errors between a human and the interface concerned. Errors are analysed here based on some experimental results, introducing the viewpoint of localization for the mechanism of errors. A major category is the notion of cusp catastrophe. A cusp catastrophe sometimes occurs in a human's processes of understanding and reasoning, which gives a sudden change in state skipping middle stages available between the two extreme opposite states. This sort of human behavior may be dangerous and give damage to machines. The aim of the present paper is to eliminate such errors.
