Abstract: A robot includes an operation control unit that selects a motion of the robot, a drive mechanism that executes a motion selected by the operation control unit, an eye control unit that causes an eye image to be displayed on a monitor installed in the robot, and a recognizing unit that detects a user. The eye control unit causes a pupil region included in the eye image to change in accordance with a relative position of the user and the robot. A configuration may be such that the eye control unit causes the pupil region to change when detecting a sight line direction of the user, or when the user is in a predetermined range.

Abstract: A game contents delivery server receives a desire to obtain contents from the player terminal with presentation of the contents ID via a communication network. The game contents delivery server creates tag data uniquely defined when the desire to obtain the contents is received from the player terminal. The game contents delivery server delivers the contents to the player terminal by adding the tag data thus created to the contents identification information and transmitting the contents to the player terminal. An online video game control server creates delivered contents data in the case where the obtained contents information in which header data are added to the obtained tag data is received from the player character. The online video game control server then registers the created delivered contents data so that the contents indicated by the obtained contents information can be utilized.
