  • Patent number: 10329047
    Abstract: The present invention relates to a collapsible virtual reality viewer. Aspects of the viewer include a body portion and a viewing portion, each having a plurality of panels abutting fold lines. The viewer may be folded along the fold lines to move from an expanded configuration to a collapsed configuration when it is not being used. In one aspect, the viewer includes a detachable panel that is removeably coupled to the viewer along a plurality of perforations. Promotional material may be printed on or attached to the detachable panel. In another embodiment, the body portion and the viewing portion are each formed of a unitary construction in which the panels of each portion are die cut from a single piece of material and folded along fold lines to form the body and viewing portions, which are then secured together at one or more locations.

  • Publication number: 20140009828
    Abstract: An improved collapsible stereoscope made of a stiff but bendable material. The stereoscope includes a front viewing panel with apertures for lenses, a rear picture holding panel, and bracing side walls, all integrally hinged to a bottom panel. Each bracing side wall varies in height so that it is tall enough in some regions to provide structural support, but short enough in other regions to reduce or prevent the casting of shadows on the stereogram. The length of each bracing side wall is longer than length of the bottom panel, so that when each bracing side wall is secured to the front panel, the bracing side walls bend in toward each other at a preformed folding crease which improves structural stability of the stereoscope, holds stereograms against the picture holding panel, and reduces shadowing on the stereogram. The collapsible stereoscope can be used as a greeting card.

  • Patent number: 8427746
    Abstract: The present invention discloses a stereoscopic image display system and a method of controlling the same. An eye tracking module locates current 3D spatial positions of the viewer's eyes, and generates the information of both left and right eyes' current 3D spatial positions. A control module controls a display device that can alter the direction of the light outputted, and outputs images on the display device in time multiplex mode. The light containing the left eye image is outputted to the position of left eye instead of right eye at one time point, and the light containing the right eye image is outputted to the position of right eye instead of left eye at another time point, so that a stereoscopic image is perceived according to the parallax theory. The present invention enlarges the visual range of stereoscopic image and achieves a better stereoscopic image visual experience for viewers.

    Abstract: A stereoviewer for observing a stereo pair of photographs three-dimensionally through binocular lenses is shown and described. The stereoviewer comprises a box-shaped main body case having a space for accommodating stereoscopic photographs; a lid for covering the main body case; holder portions provided on one side surface of the box-shaped main body case so as to position and hold the stereoscopic photographs in a non-perpendicular standing state; and binocular lenses provided thereon are inclined in such a manner that the binocular lenses face the vertical center portion of the stereoscopic photographs. This stereoviewer also serves as a package and has a simple structure. The thickness of the binocular lenses are varied so that the focal distance is different between the upper portion and the lower portion of said binocular lenses and the binocular lenses are decentered outwardly in the horizontal direction.

  • Patent number: 5204776
    Abstract: An automatic viewer for half-frame stereoprints includes a base with a pair of lenses for stereoscopic viewing mounted thereon. The base has a kicking foot and picking detent projecting therethrough for engaging openings in a carrier deck upon which the half-frame stereoprints are pivotally mounted. A control mechanism utilizes cams to coordinate movement of the kicking foot and picking detent to index the carrier deck across the base so that the photoprints may be viewed individually. The carrier deck has two rows of openings for receiving the kicker foot, allowing the viewer to advance the carrier deck from either end presenting a first set of photoprints for viewing when advancing from one end and a second set of photoprints for viewing when advanced from the opposite end. The carrier deck may be stored with other carrier decks in a binder.

  • Patent number: 5136423
    Abstract: A 3-D viewer is created by folding paper such as card stock in a predetermined manner. A first section of the viewer carries a pair of 3-D lenses and a second section, which is held normal to the plane of the first section when the viewer is in use, has a longitudinal extent substantially equal to the focal length of the lenses. In a first embodiment, a third section is foldably connected to the second section, carries a pair of 3-D scenes, and is held generally parallel to the first section when the scenes are viewed. Only one scene is provided in a second embodiment. Third and fourth embodiments add a fourth section that interconnects the free ends of the first and third sections of the first and second embodiments, respectively. That fourth section suggests to the user that the sections should be held in a square, box-like configuration. In the fourth embodiment, a foldable flap locks the viewer into the box-like configuration and serves as a septum member that facilitates viewing of the 3-D images.

  • Patent number: 5058990
    Abstract: A stereoscope includes a body having a base panel and a septum panel, wherein the front and rear edges of the base and septum panels each define at least one respective tab. A lens assembly having a lens panel that supports a pair of lenses defines multiple tab receiving slots, each positioned to receive a respective one of the tabs to support the septum panel in a pre-determined position with respect to the base panel and to hold the lens assembly on the body. A stereoscopic view panel has a pair of stereoscopic views fixedly positioned on the view panel. The view panel defines multiple tab receiving slots, each receiving a respective one of the tabs to secure the view panel to both the septum and base panels, with the septum panel precisely positioned between the stereoscopic views.

  • Patent number: RE40131
    Abstract: A handheld stereographic book-type device which includes a content support portion (8) configured to position and support stereographic content (1A, 1B), and a stereoscopic viewer (5) configured to enable interocular adjustment. The stereoscopic viewer includes adjustable left and right lenses and respective adjustable occluding apertures to enable perception of stereographic content configured with left and right peripheral monocular fields (FIGS. 7-9, 2DL & 2DR). A viewer pivotal chassis (3) is configured to couple the stereoscopic viewer to the content support portion (8). The viewer pivotal chassis includes a plurality of pivotal axes (3) parallel to a line which bisects the left and right lenses of said viewer to enable the user to visually scan and traverse up and down the length of said content while maintaining focus of said content therewith said viewer (5).
