1. An information processing device, comprising:
circuitry configured to
change an intensity of light of a light source that irradiates first and second eyes of a user with light;
receive, from an event driven vision sensor including a sensor that generates an event signal when detecting a change in intensity of a light to be incident thereon, the event signal indicating a position and a time of the change in intensity of the light reflected in first and second regions of the first eye and in third and fourth regions of the second eye of the user;
identify the light source corresponding to the event signal based on the event signal and positions of the eyes of the user, the light source, and the vision sensor; and
detect a visual line of the user according to the identified light source, wherein
the first and second regions are adjacent to a pupil of the first eye and the third and fourth regions are adjacent to a pupil of the second eye,
the first region is at an outer corner side of the pupil of the first eye,
the second region is at an inner corner side of the pupil of the first eye,
the third region is at an inner corner side of the pupil of the second eye, and
the fourth region is at an outer corner side of the pupil of the second eye.
