An information processing device according to the present disclosure includes a correction section that corrects a position of a virtual camera on the basis of first information regarding a height of a visual line of a performer in a virtual space and second information regarding a height of the virtual camera linked with a viewer in the virtual space. ## Claims ### Claim 1 An information processing device, comprising: a correction section configured to correct a position of a virtual camera in a virtual space based on a movement direction of a performer in the virtual space, first information regarding a height of a visual line of the performer in the virtual space, and second information regarding a height of the virtual camera, wherein the virtual camera is linked with a viewer in the virtual space, and the height of the visual line of the performer and the height of the virtual camera are with respect to a plane in the virtual space. ### Claim 2 (depends on 1) The information processing device according to claim 1, wherein the correction section is further configured to correct the height of the virtual camera. ### Claim 3 (depends on 2) The information processing device according to claim 2, wherein the correction section is further configured to correct the height of the virtual camera in such a way that the virtual camera is directed to a face of the performer. ### Claim 4 (depends on 1) The information processing device according to claim 1, wherein the first information includes information regarding at least one of a direction of the visual line of the performer or an angle of a head of the performer, the second information includes information regarding an angle of the virtual camera, and the correction section is further configured to correct the angle of the virtual camera based on a basis of the first information and the second information. ### Claim 5 (depends on 4) The information processing device according to claim 4, wherein the correction section is further configured to correct the angle of the virtual camera in such a way that the virtual camera is directed to a face of the performer. ### Claim 6 (depends on 1) The information processing device according to claim 1 further comprising a control section configured to move a position of the viewer in the virtual space based on the movement direction of the performer. ### Claim 7 (depends on 1) The information processing device according to claim 1, further comprising a control section configured to control, based on a position of the viewer in the virtual space, at least one of the movement direction of the performer or an angle of the performer. ### Claim 8 (depends on 1) The information processing device according to claim 1, wherein the correction section is further configured to: correct the position of the virtual camera in a case where the viewer is present in the movement direction of the performer; and does not correct the position of the virtual camera in a case where the viewer is not present in the movement direction of the performer. ### Claim 9 (depends on 1) The information processing device according to claim 1, wherein a plurality of performers is present in the virtual space, the plurality of performers includes the performer, the performer is present in a direction to which the virtual camera is directed, and the correction section is further configured to: select, from among the plurality of performers, the performer who is present in the direction to which the virtual camera is directed; and correct the position of the virtual camera based on the first information on the selected performer. ### Claim 10 (depends on 1) The information processing device according to claim 1, further comprising a control section configured to cause, based on the correction of the position of the virtual camera, the performer to make a reaction to indicate that a visual line of the viewer is opposed to the visual line of the performer. ### Claim 11 (depends on 1) The information processing device according to claim 1, further comprising a virtual camera position control section configured to: temporarily move the virtual camera to a specific position in the correction of the position of the virtual camera; and move the position of the virtual camera to the corrected position of the virtual camera subsequent to completion of the correction. ### Claim 12 (depends on 1) The information processing device according to claim 1, further comprising a detection section configured to detect the first information from content information including the performer. ### Claim 13 (depends on 1) The information processing device according to claim 1, further comprising a virtual camera position control section configured to: acquire, from a head device mounted on a user linked with the virtual camera, the second information regarding a position of the head device, wherein the user corresponds to the viewer; and control the position of the virtual camera based on the second information. ### Claim 14 (depends on 13) The information processing device according to claim 13, further comprising a control section configured to: generate an image based on the position of the virtual camera; and display the image on a monitor of the head device. ### Claim 15 An information processing method, comprising: correcting a position of a virtual camera in a virtual space based on a movement direction of a performer in the virtual space, first information regarding a height of a visual line of the performer in the virtual space, and second information regarding a height of the virtual camera, wherein the virtual camera is linked with a viewer in the virtual space, and the height of the visual line of the performer and the height of the virtual camera are with respect to a plane in the virtual space. ### Claim 16 An information distribution system, comprising: a distribution server configured to distribute content information including a performer; a control section configured to: place the performer in a virtual space based on the content information; and place a virtual camera linked with a viewer in the virtual space; and a correction section configured to correct a position of the virtual camera in the virtual space based on a movement direction of the performer in the virtual space, first information regarding a height of a visual line of the performer, and second information regarding a height of the virtual camera, wherein the height of the visual line of the performer and the height of the virtual camera are with respect to a plane in the virtual space.
