This involves mathematical relationships between these visual cues and the vehicle state variables. The visual scene provides a variety of perspective geometrical and relative motion cues. Experimental results support the hypothesis that these characteristics can be considered as separate cues among which the human operator must divide his attention. No interference was found between tasks. The visual scene perception model is shown capable of providing a general framework for dealing quantitatively with the important visual scene characteristics. Integrating this model with the optimal control model of human control behavior allows a detailed description of the visual perception process involved in the visual approach task. 收起
