Abstract: A method includes defining a virtual space associated with a first user, wherein the virtual space includes a first object associated with a second user and a second object different from the first object. The method further includes selecting the first object in response to input by the first user. The method further includes associating the selected first object with the second object within the virtual space in response to input by the first user. The method further includes establishing communication between the first user and second user associated with the first object in response to the first object and the second object being associated with each other.

Abstract: A method includes defining a virtual space including a virtual camera, a character object, and a field in which the character object is movable, the field defining a peripheral direction and surrounding the virtual camera along the peripheral direction. The method includes defining a visual field of the virtual camera. The method includes displaying a visual-field image on a head-mounted display based on the visual field. The method includes detecting a movement input including a lateral-direction component, the lateral-direction being different from the peripheral direction. The method includes moving the character object in the field along the peripheral direction in response to the lateral-direction component of the movement input. The method includes detecting movement of the head-mounted display and changing a direction of the virtual camera based on detected movement of the head-mounted display. The method includes updating the visual-field image based on the direction of the virtual camera.
