[Solution] There is provided a control device including: an acquisition unit configured to acquire position attitude information regarding a position or an attitude of an object related to a user manipulation located at a different position from a head of a user; and a control unit configured to control an image visual field which is a range displayed as an image on a display device mounted on the head of the user based on the position attitude information. ## Claims ### Claim 1 A control device comprising: an acquisition unit configured to acquire position attitude information regarding a position or an attitude of an object related to a user manipulation located at a different position from a head of a user; and a control unit configured to control an image visual field which is a range displayed as an image on a display device mounted on the head of the user based on the position attitude information. ### Claim 2 (depends on 1) The control device according to claim 1, wherein the image visual field includes at least a part of a virtual space. ### Claim 3 (depends on 2) The control device according to claim 2, wherein the acquisition unit acquires position attitude information regarding the head of the user, and based on a situation of the user, the control unit selects one of a first image visual field specified by the position attitude information regarding the object related to the user manipulation and a second image visual field specified by the position attitude information regarding the head of the user as a range to be displayed as the image. ### Claim 4 (depends on 3) The control device according to claim 3, wherein the control unit selects the second image visual field when a predetermined user manipulation is performed. ### Claim 5 (depends on 4) The control device according to claim 4, wherein the control unit selects the second image visual field when the positions or the attitudes of the object related to the user manipulation and the head of the user are changed in mutually different directions. ### Claim 6 (depends on 3) The control device according to claim 3, further comprising: a determination unit configured to determine whether the user is in a visually induced motion sickness state, wherein the control unit selects the second image visual field when the determination unit determines that the user is in the visually induced motion sickness state. ### Claim 7 (depends on 6) The control device according to claim 6, wherein the determination unit determines that the user is in the visually induced motion sickness state when a displacement of the head of the user is equal to or greater than a threshold. ### Claim 8 (depends on 3) The control device according to claim 3, wherein the control unit selects one of the first image visual field and the second image visual field based on whether the user is a manipulator of the first image visual field. ### Claim 9 (depends on 3) The control device according to claim 3, wherein the control unit performs control such that a correspondence object corresponding to the object related to the user manipulation is displayed in an image generated based on the first image visual field. ### Claim 10 (depends on 9) The control device according to claim 9, wherein the correspondence object indicates at least a part of the object related to the user manipulation. ### Claim 11 (depends on 9) The control device according to claim 9, wherein the correspondence object is different according to a shape or a kind of the object related to the user manipulation. ### Claim 12 (depends on 3) The control device according to claim 3, wherein the control unit controls a broadness of the first image visual field according to a manipulation amount of the user manipulation. ### Claim 13 (depends on 3) The control device according to claim 3, wherein the object related to the user manipulation includes a virtual object on a virtual space, and the first image visual field includes an image visual field specified based on a position attitude of the virtual object. ### Claim 14 (depends on 13) The control device according to claim 13, wherein the object related to the user manipulation includes a manipulation object, and when a position or an attitude of only a part of the manipulation object is changed, the control unit changes a movement speed of the virtual object on the virtual space according to a change amount of the position or the attitude of the part of the manipulation object. ### Claim 15 (depends on 13) The control device according to claim 13, wherein the control unit controls the first image visual field based on the position attitude information regarding the head of the user. ### Claim 16 (depends on 9) The control device according to claim 9, wherein the control unit performs control such that an object indicating another user different from the user is displayed in the first image visual field or the second image visual field. ### Claim 17 (depends on 1) The control device according to claim 1, wherein the image visual field includes a part of a real space. ### Claim 18 (depends on 17) The control device according to claim 17, wherein the image visual field includes a range of a subject in imaging of an imaging device. ### Claim 19 A control method comprising: acquiring position attitude information regarding a position or an attitude of an object related to a user manipulation located at a different position from a head of a user; and controlling an image visual field which is a range displayed as an image on a display device mounted on the head of the user based on the position attitude information. ### Claim 20 A program causing a computer to realize: an acquisition function of acquiring position attitude information regarding a position or an attitude of an object related to a user manipulation located at a different position from a head of a user; and a control function of controlling an image visual field which is a range displayed as an image on a display device mounted on the head of the user based on the position attitude information.
