1. A method for searching a preferred retinal locus of a visual field damage of a patient, the method being performed by an apparatus, the method comprising:
providing a first stimulus to the patient through a stimulus providing device interworking with the apparatus;
receiving a response to the first stimulus from the patient through the stimulus providing device;
analyzing a motion of a head of the patient, which corresponds to the first stimulus, when the response is a correct answer; and
specifying the preferred retinal locus based on an analysis result,
wherein the preferred retinal locus is a specific area among a peripheral vision area of the patient, in which the patient recognizes an object and is set as a target for training of at least one of an eyesight and a visual cognitive ability of the patient, with a second stimulus being provided,
wherein the first stimulus includes a behavioral task for finding the first stimulus presented to a dead center of a screen of the stimulus providing device and determining whether an orientation is transverse or longitudinal, in a state, in which eyes of the patient are fixed to the dead center of the screen by using two line segments that intersect the dead center of the screen of the stimulus providing device, to searching the preferred retinal locus, and
wherein the second stimulus includes a training task provided, after the first stimulus, to the preferred retinal locus of the patient that recognizes the object, the training task is a temporal two alternative forced choice (temporal 2-AFC) task using a target stimulus and a peripheral stimulus of a collinear array provided at the preferred retinal locus of the patient, and requiring a response to a number of the screen that is presented together with the target stimulus positioned at a center of the collinear array.
