The video shows the behaviour of the system for the selected letter and dimension. The top left part shows how the eye moves on the letter. The big green square corresponds to the image portion perceived with the eye periphery while the inner little green square corresponds to the image portion perceived by the high resolution fovea. The top central part is a record of eye movements since the beginning of the trial. In the top right part of the video the visual input is shown: the two squares show what the eye periphery (left) and the eye fovea (right) perceive in the current time step. Below them the "ANSWER OK" or "ERROR" text indicates whether the system is giving the right or wrong answer respectively (they appear after the first 50 steps have passed). The lower part of the video shows the categorization output neurons activation through time. Each color corresponds to a letter: letter "l" is black, letter "u" is red, letter "n" is blue, letter "o" is green and letter "j" is purple. This information is also shown below the graph (the "c" before the letter as in "cl" stands for "categorization output"). To ease the identification of the line corresponding to the right answer, such line is drawn thicker than the others.
