EVALUATION APPARATUS, EVALUATION METHOD, AND NON-TRANSITORY STORAGE MEDIUM

1 . An evaluation apparatus comprising:

a display;

a detecting unit configured to detect a position of a gaze point of a subject;

a display controller configured to display an evaluation image including a main target and multiple sub-targets, and instruction information which is an image for explicitly instructing the subject to gaze at the main target on the display, and then to hide the instruction information;

an region setting unit configured to set determination regions corresponding to the main target and the multiple sub-targets;

a determination unit configured to determine, after hiding the instruction information, whether the gaze point is positioned within the determination regions based on the detected position of the gaze point;

an arithmetic unit configured to calculate a movement count by which the gaze point has moved from one of the determination regions to another based on a determination result of the determination unit; and

an evaluation unit configured to acquire evaluation data of the subject based on the movement count.

2 . The evaluation apparatus according to claim 1 , wherein the main target and the multiple sub-targets are of a same type.

3 . The evaluation apparatus according to claim 1 , wherein the display controller further configured to display the multiple sub-targets in a different display mode without changing a display mode of the main target.

4 . The evaluation apparatus according to claim 1 , wherein the display controller further configured to display regions other than the main target at a lower luminance.

5 . An evaluation method comprising:

detecting a position of a gaze point of a subject;

displaying an evaluation image including a main target and multiple sub-targets, and instruction information which is an image for explicitly instructing the subject to gaze at the main target on a display, and then to hide the instruction information;

setting determination regions corresponding to the main target and the multiple sub-targets;

determining, after hiding the instruction information, whether the gaze point is positioned within the determination regions based on the detected position of the gaze point;

calculating a movement count by which the gaze point has moved from one of the determination regions to another based on a determination result; and

acquiring evaluation data of the subject based on the movement count.

6 . A non-transitory storage medium that stores an evaluation program causing a computer to execute:

a process of detecting a position of a gaze point of a subject;

a process of displaying an evaluation image including a main target and multiple sub-targets, and instruction information which is an image for explicitly instructing the subject to gaze at the main target on a display, and then to hide the instruction information;

a process of setting determination regions corresponding to the main target and the multiple sub-targets;

a process of determining, after hiding the instruction information, whether the gaze point is positioned within the determination regions based on the detected position of the gaze point;

a process of calculating a movement count by which the gaze point has moved from one of the determination regions to another based on a determination result; and

a process of acquiring evaluation data of the subject based on the movement count.
