The earlier work established that search depends on geometric and kinematic factors such as observer and target positions and motions, and introduced probability only through specific relative positions. The present paper investigates the uncertainties inherent in detection under various specific conditions of contact. The authors develop a set of probabilistic methods for detection that treat each visual glimpse as an independent trial, tailored to the specific situation.
“Kinematic bases,” the first paper of this series, discussed the geometric and kinematic factors involved in search—the positions, motions, and contacts of observers and targets. Probability was introduced only in assuming specific relative positions for the observer and target. The present paper discusses the uncertainties inherent in the act of detection under various specific conditions of contact. In the course of the discussion a body of methods for applying probability to problems of detection is developed. It must be emphasized, however, that these methods are conditioned by the particular situation in the case of visual detection because the different elementary acts of looking or “glimpses” are essentially independent trials. The reason for the distinction follows.
