1. An evaluation device comprising:
a display configured to display images;
a gaze point detecting unit configured to detect a positional data of a gaze point of a subject who observes the display;
a display controller configured to display a task target object that includes a task feature portion and that is to be gazed at by the subject and instruction information that is a task related to the task target object on the display, and to display, after displaying the task target object and the instruction information, a specific target object that includes a specific feature portion corresponding to the task feature portion and that is a correct answer to the instruction information and comparison target objects each of which differs from the specific target object on the display;
an area setting unit configured to set a specific area for an entirety of the specific target object, a specific feature area for the specific feature portion which is part of the specific target object, and comparison areas for the comparison target objects on the display;
a determination unit configured to determine, based on the positional data of the gaze point, whether the gaze point is present in each of the specific feature area and the comparison areas;
an arithmetic unit configured to calculate, based on a determination result by the determination unit, a gaze point transition data in a target display period; and
an evaluating unit configured to obtain, based on the gaze point transition data in the target display period, an evaluation data of the subject by applying different weightings to a case in which the gaze point is present in the specific feature area and to a case in which the gaze point is not present in the specific feature area but is present in the specific area.
