Information processing device, information processing method, and program

An information processing method comprising:

• obtaining viewpoint information related to viewpoint of user;
• obtaining position-related information related to position of the user and position of predetermined object;
• obtaining head rotation information related to angular velocity accompanying rotation of head region of the user and related to changes in the angular velocity;
• and
• determining, based on a gazing score which is calculated for each object according to the position-related information and the head rotation information and which indicates extent of gazing of the user with respect to the object, whether or not the user is gazing at the object.

A program that causes a computer to function as:

• a viewpoint information obtaining unit that obtains viewpoint information related to viewpoint of user;
• a position-related information obtaining unit that obtains position-related information related to position of the user and position of predetermined object;
• a head rotation information obtaining unit that obtains head rotation information related to angular velocity accompanying rotation of head region of the user and related to changes in the angular velocity;
• and
• a determining unit that, based on a gazing score which is calculated for each object according to the position-related information and the head rotation information and which indicates extent of gazing of the user with respect to the object, determines whether or not the user is gazing at the object.
