Abstract: An information processing apparatus includes a processor and a memory with instructions thereon. The instructions upon execution by the processor, causes the processor to: sequentially sense a movement of a body of a user; present, to the user, an avatar corresponding to the user, rather than a photographed image of an appearance of the user, based on a result of the sensing so that the user perceives a shape of a surface of the body of the user; determine a position of a figure object to be drawn that serves as a guide for movement of the body of the user in association with the avatar based on the result of the sensing; and display the figure object at the determined position.

Abstract: A program causes a computer to estimate, based on a result of sensing a surface of the body of a target, a plurality of joint points corresponding to joints in the body of the target; set a first type line segment for at least one of the plurality of joint points in a two dimensional base image that represents the body surface of the target, the first type line segment passing through the joint point; and identify an intersection at which the first type line segment intersects with the body surface of the target in the base image.

Abstract: A game device executes a game in which a manipulated character is brought up. When a first manipulation input is accepted, the game device controls events that are generated for a manipulated character in the game and require manipulation inputs by the user of the game device so that a non-generation state, in which their generation is not allowed, is entered. Accordingly, restrictions involved in the behavior of the user are reduced.
