Abstract: An information processing apparatus includes an acquisition unit configured to acquire a position and orientation of a virtual viewpoint and a position and orientation of each of one or more virtual objects, a movement unit configured to move the virtual viewpoint, a control unit configured to control each of the one or more virtual objects to be interlocked or not to be interlocked with movement of the virtual viewpoint based on whether the virtual object satisfies a predetermined condition, and a generation unit configured to generate a virtual image including the controlled one or more virtual objects at a viewpoint as a result of moving the virtual viewpoint.

Abstract: An information processing apparatus includes a first acquisition unit for acquiring an actual viewpoint position and orientation and a virtual viewpoint position and orientation of a first user, a second acquisition unit for acquiring an actual viewpoint position and orientation and a virtual viewpoint position and orientation of a second user, and a correction unit for correcting the virtual viewpoint position and orientation of the first user based on the virtual viewpoint position and orientation of the second user and a relative position and orientation between the actual viewpoint position and orientation of the first user and the actual viewpoint position and orientation of the second user.

Abstract: An information processing apparatus that shares with another user a space where a virtual three-dimensional model is presented includes at least one processor and/or at least one circuit configured to acquire information about an actual viewpoint of the another user, and generate a video effect based on the information about the actual viewpoint of the another user in a case where a virtual viewpoint of the another user is different from the actual viewpoint of the another user because a walk-through function is used.
