Visual detection of compound motion

Abstract

Results of previous studies suggest that under certain geometric conditions the rate of change of the relative bearing (ω) between 2 moving objects is used as a cue to predict their future positions in space. 4 Os were studied in 4 situations representing an abstraction of these geometric conditions. Their task was to detect a rotary motion superimposed on translational motion. The results indicate that ω was the primary cue used in this task; detection performance was a linear function of ω.
