Disambiguating complex visual information: towards communication of personal views of a scene.
Two experiments on the perception and eye-movement scanning of a set of six overtly ambiguous pictures are reported. In the first experiment it was shown that specific perceptual interpretations of an ambiguous picture usually correlate with parameters of the gaze-position distributions. In the second experiment these distributions were used for an image processing of initial pictures in such a way that in regions which attracted less fixations the brightness of all elements was lowered. The preprocessed pictures were then shown to a group of 150 naïve subjects for an identification. The results of this experiment demonstrated that in four out of six pictures it was possible to influence perception of other persons in the predicted way, ie to shift spontaneous reports of naïve subjects in the direction of interpretations that accompanied gaze-position data used for the preprocessing of initial pictures. Possible reasons for a failure of such a communication of personal views in two cases are also discussed.
