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 information processing apparatus acquires, using an image obtained by capturing a device including a light-emitting marker with exposure times shorter than a time corresponding to one frame, information regarding a position and a posture of the device. The light-emitting marker is caused to emit light for light emission times equal to or shorter than the exposure times. The information processing apparatus causes the light-emitting marker to emit light in a predetermined flashing pattern, and identifies the exposure times on a time axis of the device on the basis of whether or not the image appears in the captured image, to thereby synchronize the exposure and the light emission.
