Abstract

An avatar control device for controlling an avatar to be displayed within a virtual space acquires a face image of a user captured by a camera, acquires initial setting information indicating a reference posture of a face of the user, acquires posture information indicating a posture of the face of the user for the camera on the basis of the face image, and controls forward or backward movement of the avatar within the virtual space on the basis of a distance between the camera and the face of the user indicated in the initial setting information and the posture information; and controls a movement direction of the avatar within the virtual space on the basis of an orientation of the face of the user for the camera.

First claim

1 . An avatar control device for controlling an avatar to be displayed within a virtual space, wherein the avatar control device;
acquires a face image of a user captured by a camera; acquires initial setting information indicating a reference posture of a face of the user; acquires posture information indicating a posture of the face of the user for the camera on a basis of the face image; controls forward or backward movement of the avatar within the virtual space on the basis of a distance between the camera and the face of the user indicated in the initial setting information and the posture information; and controls a movement direction of the avatar within the virtual space on the basis of an orientation of the face of the user for the camera.

2 . An avatar control device for controlling an avatar displayed as an alter ego of a user within a virtual space, wherein the avatar control device;
acquires a face image that is an image of a face of the user who visually recognizes an image of the virtual space displayed on a display unit, the image being captured by a camera; acquires initial setting information indicating a reference posture of the face of the user; acquires posture information indicating a posture of the face of the user for the camera on a basis of the face image; and controls lateral movement of the avatar within the virtual space on the basis of a displacement angle from the reference posture of the face of the user indicated in the initial setting information and the posture information.

3 . The avatar control device according to claim 1 , wherein the avatar control device controls a forward or backward movement velocity or acceleration in accordance with a magnitude of a distance between the camera and the face of the user, or a change rate of the distance.

4 . The avatar control device according to claim 1 , wherein the avatar control device;
detects a predetermined operation of the user captured by the camera; and prevents avatar movement control from being performed when the predetermined operation has been detected.

5 . An avatar control method for controlling an avatar to be displayed within a virtual space, the avatar control method comprising:
acquiring a face image of a user captured by a camera; acquiring initial setting information indicating a reference posture of a face of the user; acquiring posture information indicating a posture of the face of the user for the camera on a basis of the face image; controlling forward or backward movement of the avatar within the virtual space on the basis of a distance between the camera and the face of the user indicated in the initial setting information and the posture information; and controlling a movement direction of the avatar within the virtual space on a basis of an orientation of the face of the user for the camera.
