Claim 7:
8. A computer program stored on a computer-readable storage medium, wherein the computer program, when executed on at least one processor of a device, the at least one processor performs processes of identifying dementia of a user, the processes comprising:
a process of performing a first task causing a first object configured to be displayed on a first region of a screen displayed on a user terminal configured so as to induce the user's gaze of the user terminal to stare at the first region;
a process of causing at least one camera of the user terminal to acquire an image of the user's eye while the first task is performed;
a process of recognizing, by analyzing the image of the user's eye acquired while the first task is performed, that the user is staring at the first object for a preset time by recognizing that a central point position of the user's pupil exists within a preset region, wherein the preset region corresponds to a region in which the central point position of the user's pupil is located when the user's eye stares at a center of the screen, and wherein the image comprises a plurality of pixels; and
after recognizing that the user has stared at the first object for the preset time, a process of performing a second task causing at least one object, which induces the user's gaze to move to a region other than the first region instead of the first object on the screen of the user terminal, configured to be displayed in a region other than the first region, wherein the first task and the second task are performed a preset number of times;
a process of causing the at least one camera of the user terminal to acquire another image of the user's eye while the second task is performed the preset number of times;
by analyzing the another image of the user's eye, a process of generating gaze information related to the user while the second task is performed the preset number of times; wherein the gaze information comprises at least one of information on a number of times that the user correctly performed a preset gaze task, information on a number of times the user failed to perform the preset gaze task correctly, information on whether the user's gaze continues to stare at a specific point for the preset time, information on a time elapsed from a time point that a screen comprising the at least one object is displayed to a time point that the user's gaze moves to any one of the at least one object, information on a movement speed of the user's gaze, and information on whether the user's gaze is accurately staring at a point related to the preset gaze task;
a process of calculating a score by inputting the gaze information into a dementia identification model; and
a process of determining whether the user has dementia based on the score;
wherein either:
(a) the at least one object comprises text: displayed instead of the first object on the first region; and a second object and third object respectively displayed in a second region and third region different from the first region; and
the first region is located between the second region and the third region; and
the preset gaze task comprises at least one of: a task to stare at an object related to a meaning of the text among the second object and the third object; and a task to stare at an object related to a color of the text among the second object and the third object; or
(b) the at least one object comprises a gaze-inducing object displayed in any one area of a second region and third region different from the first region; and
the first region is located between the second region and the third region; and
the preset gaze task comprises a task to stare in a direction opposite to a direction in which the gaze-inducing object is located.
