A program comprising instructions that, when executed by a computer, cause the computer to execute: processing that detects that viewing is being performed for a book that is provided for reading on which details corresponding to a predetermined story are printed and that is registered in advance; processing that, for a target book for which it is detected that viewing is being performed, identifies a progression position in the viewing in a story corresponding to the book; and processing that starts presentation of binocular stereoscopic content associated with the progression position in the viewing that is identified; wherein the presentation of binocular stereoscopic content is performed using a see-through head-mounted display having a display apparatus, cameras which are arranged at positions corresponding to each eye of a user, and sensors configured to detect the direction in which the user is facing; wherein the program further causes the computer to, prior to the processing that starts presentation: - receive an output of the cameras or the sensors, - detect the posture of the head-mounted display, - store the posture of the head-mounted display in a memory as state information; - execute an introduction dramatization process in which, based on state information obtained in respect of the head-mounted display that signifies that the user's head is tilted forward as for reading, a dramatization is performed to prompt the user to raise their head into a facing-ahead posture for the viewing of binocular stereoscopic content; and wherein the presentation of binocular stereoscopic content comprises: displaying images captured by the cameras on the display apparatus, and transitioning to a display of images in which additional image elements are superimposed in a region corresponding to the book on the images, the transitioning being such that ultimately only images corresponding to provision content are displayed, and visual information of the outside world, from the cameras, is blocked. processing that detects that viewing is being performed for a book that is provided for reading on which details corresponding to a predetermined story are printed and that is registered in advance; processing that, for a target book for which it is detected that viewing is being performed, identifies a progression position in the viewing in a story corresponding to the book; and processing that starts presentation of binocular stereoscopic content associated with the progression position in the viewing that is identified; wherein the presentation of binocular stereoscopic content is performed using a see-through head-mounted display having a display apparatus, cameras which are arranged at positions corresponding to each eye of a user, and sensors configured to detect the direction in which the user is facing; wherein the program further causes the computer to, prior to the processing that starts presentation: - receive an output of the cameras or the sensors, - detect the posture of the head-mounted display, - store the posture of the head-mounted display in a memory as state information; - execute an introduction dramatization process in which, based on state information obtained in respect of the head-mounted display that signifies that the user's head is tilted forward as for reading, a dramatization is performed to prompt the user to raise their head into a facing-ahead posture for the viewing of binocular stereoscopic content; and - receive an output of the cameras or the sensors, - detect the posture of the head-mounted display, - store the posture of the head-mounted display in a memory as state information; - execute an introduction dramatization process in which, based on state information obtained in respect of the head-mounted display that signifies that the user's head is tilted forward as for reading, a dramatization is performed to prompt the user to raise their head into a facing-ahead posture for the viewing of binocular stereoscopic content; and wherein the presentation of binocular stereoscopic content comprises: displaying images captured by the cameras on the display apparatus, and transitioning to a display of images in which additional image elements are superimposed in a region corresponding to the book on the images, the transitioning being such that ultimately only images corresponding to provision content are displayed, and visual information of the outside world, from the cameras, is blocked. displaying images captured by the cameras on the display apparatus, and transitioning to a display of images in which additional image elements are superimposed in a region corresponding to the book on the images, the transitioning being such that ultimately only images corresponding to provision content are displayed, and visual information of the outside world, from the cameras, is blocked.
