Abstract: An image forming device tracks a state of a head mounted display by Visual SLAM on the basis of a captured image of a space around a user wearing the head mounted display. The image forming device determines keyframes collated with a current frame during (a) setting of a play area (step S50), and classifies some of the determined keyframes into keyframes prohibiting discard (step S52). The image forming device reads stored keyframe data and uses the read keyframe data for tracking during (b) execution of an application (step S60). The image forming device adds keyframes and discards pieces of data of keyframes allowing discard according to movement of the user (step S64).

Abstract: An image forming device stores a play area where a user wearing a head mounted display is movable during play of an application in a space around the user. The image forming device causes the head mounted display to display an image indicating the stored play area. The image forming device receives an operation performed by the user to edit the play area. The image forming device expands or reduces the play area according to the operation performed by the user.

Abstract: Provided is an image generation device which detects an obstacle that is present in the surrounding space, on the basis of a captured image obtained by a stereo camera of a head-mounted display, and sets a boundary 72 of a play area in which a user wearing the head-mounted display is allowed to move. When a new obstacle is detected inside the play area, the image generation device generates tangent lines 82a and 82 from an observation point H on a floor surface to a contour 80 of the obstacle and uses the tangent lines and a portion which is a part of the contour 80 and which is between tangent points AB to set a new boundary 86 of the play area.

Abstract: Provided are a boundary display control device, a boundary display control method, and a program which can reduce an oppressive feeling of a user when a virtual object representing a boundary surface dividing a region in a real space in which the user is permitted to exist from a region in the real space in which the user is not permitted to exist is displayed. A program executing section (84) locates a position of the user wearing a head-mounted display. An approach portion identifying section (86) identifies, as an approach portion, a part of a boundary surface dividing a permitted region that is the region in the real space in which the user is permitted to exist from an unpermitted region that is the region in the real space in which the user is not permitted to exist, on the basis of the located position of the user. A display control section (92) causes the head-mounted display to display a virtual object representing the identified approach portion.
