Abstract: Provided is an information processing device including a light source control section that changes intensity of light of a light source which irradiates eyes of a user, a reception section that receives, from an event driven vision sensor including a sensor which 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 by the eyes of the user, and a visual line detection section that identifies the light source corresponding to the event signal on the basis of a relative positional relation among the eyes of the user, the light source, and the vision sensor, and of the event signal generated at the same time that control is carried out by the light source control section, to detect a visual line of the user.
