An information processing device according to the present technology includes a controller. The controller is configured to acquire first position-and-pose information related to a position and a pose of hardware that is used to calibrate a line of sight, and second position-and-pose information related to a position and a pose of the hardware, the second position-and-pose information being different from the first position-and-pose information; to control a display section to display a plurality of presented gaze points including a first presented gaze point and a second presented gaze point, the first presented gaze point being presented at a first position, the second presented gaze point being presented at a second position different from the first position; to control an image-capturing section to acquire a first image of an eyeball of a user gazing at the first presented gaze point, and a first image of the eyeball of the user gazing at the second presented gaze point; to generate a plurality of pieces of calibration data using the first position-and-pose information, the second position-and-pose information, and the first images; and to perform a correction related to an optical-axis vector and a visual-axis vector with respect to the eyeball of the user, using the plurality of pieces of calibration data.
