Disambiguating Complex Visual Information: Towards Communication of Personal
Views of a Scene

Abstract
Two experiments on perception and eye-movement scanning of a set of 6 overtly ambiguous
pictures are reported. In the first experiment it was shown that specific percetual
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 pre-processed pictures
were then shown to a group of 150 naive subjects for an identification. The results of
this experiment demonstrated that in 4 out of 6 pictures it was possible to influence
perception of other persons in the predicted way, i.e. to shift spontaneous reports of
naive subjects in the direction of interpretations that accompanied gaze-position data
used for the pre-processing of initial pictures. Possible reasons for a failure of such a
communication of personal views in two cases are also discussed.
