Abstract: An image forming device automatically detects a play area in reference to a camera image that indicates a space around a user and that is captured by a camera of a head mounted display. The image forming device causes the head mounted display to display an image representing the play area automatically detected. The image forming device receives an operation performed by the user to edit the play area from a controller, and changes a shape of the play area according to the operation.

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: A stereo camera of a head-mounted display photographs left-viewpoint and right-viewpoint photographed images and the like at a frame rate of 1/Δt as depicted in (a). By using either one of the left-viewpoint and right-viewpoint photographed images, a display control device alternately generates a left-eye or right-eye display image (display image, for example) for each frame at a rate equal to the frame rate used in photographing, and displays the generated display image in a corresponding region of a display panel while not displaying any image in the other region, as depicted in (c).
