Analysis of Visual Discriminations in Helicopter Control.
Abstract
The visual Discrimination Analysis is a method of examining the cue structure of the helicopter pilot's visual environment. It is hypothesized that the critical cue is the relationship between two referents--a fixed internal referent placed on the helicopter windscreen and an external referent located on the ground plane. Cue value is analyzed through the geometric relationships of these referents for the six degrees-of-freedom: pitch, roll, yaw, altitude, range, and latitude. The pilot's ability to detect perturbation will depend upon its magnitude, initial state of the craft, location of the internal and external referents, and his threshold for detecting the relative motion of two points. A mathematical model is used to generate data for a sample analysis of pitch, and the data are graphed to explore referent placements that provide detectable cues. The 'information density plot' is then developed as a means of examining the cue value of an entire field of external referents with respect to one or more internal referents. (Author)
