Abstract
Abstract Kalman filtering, and similar statistical analyses, have been widely adopted to provide the operator with statistical information as an aid in object location tasks. However, there is little available research to indicate how the operator will use the information to make judgements about the standard deviations associated with the current and future predicted estimates of the coordinates of an object's location. Hence an experiment was carried out to observe and analyse subjects' judgements associated with the estimated coordinates of an object moving in a two dimensional space. The results lead to the conclusion that naive subjects make judgements of standard deviations which can be related to the spread of the point estimates of an object's coordinates. The judgements of standard deviation were not related to the measures of variability associated with the generation of the track. These conclusions are discussed in terms of matching the man to the mathematics of the software generating the display.
