Attention Attraction in Circular Perception of a Three- Dimensional Object

The article is dedicated to the parametric analysis of a trajectory of circular rotation of a three-dimensional object during its perceptual inspection and emphasizes the difference in the psychological mechanism of distribution of a person attention from the mechanism of saccadic eye movement during perception of the video scene. According to the result, when the image of the three-dimensional object scanned with eyes there are saccades and fixed points of attention. The difference between perception of a physical object and its virtual image lays in necessity of physical action to go around the object or rotate it with the hand. So, there is a hypothesis the motive to form a full virtual image of the object consists of consequence of discrete motives, like: look at the object from left, from right, from behind, from top. In that case a person has a freedom of choice which discrete motive to implement and do it consciously. Perception of parameters of the object occurs during its rotation with an accent on the points of interest. In that points attention attracted and kept for some time, comprehension of perceived scene occurred, and the new motive generated. In the point of interest, the observation trajectory makes a maneuver and this fact support the hypothesis. The maneuvers reflect change of cognitive motives. The topology of the object image formed as a graph with vertices and vectors with azimuths and lengths of vertex connections as vector-defined edges of the graph. The results of the study are applicable in ergonomic design and prediction of human perceptual actions in new cognitive situations.
