A cone for use in a Pepper's Ghost illusion includes a conical wall of semi-reflective material, and an attachment member for removably attaching the cone to the surface of a light emissive display, and a method of displaying a Pepper's Ghost illusion includes positioning a cone of semi-reflective material onto a light emissive display; and displaying on the light emissive display an image that has been distorted by an inverse of a distortion caused by a reflection of the cone.

A head-mounted display apparatus includes: a first body including a front face having a vision hole and a rear face formed in the shape of a diving mask to cover up a user's nose and eyes; a first external body extending forward from the rear face of the first body to the front face of the first body and being spaced apart from a side surface of the first body and surrounding the side of the first body; a second body including a front face opened and a rear face having a lens mounting hole to which with a lens fixed; and a second external body extending rearward from the front face of the second body to the rear face of the second body and being spaced apart from a side surface of the second body.

A foldable virtual reality display device that includes a central board, which is provided with image displays in the user's viewing direction; first and second hinges provided at the front end and the rear end of the central board; left and right image plates folded toward left and right surfaces of the central board with respect to the first hinge; and left and right lens plates folded toward both left and right surfaces of the central board with respect to the second hinge. When used, the optical axis of the left and right image plates corresponds to the optical axis of the left and right lenses, and simultaneously corresponds to the focal distance between the left and right lenses, and when carried, the left and right image plates and the left and right lens plates are folded with respect to the both left and right surfaces of the central board.

A portable virtual reality device, which is provided with a board having a length to correspond to the focal distances of the left and right lens; a supporting board that is deployed and foldable based on the board; left and right lens plates that are deployed and folded left and rightward on a rear surface of the board based on the board. The smart phone is mounted simply to correspond to the focal distances of the left and right lens when it is used, and when it is carried, the left and right lens plates and the supporting board are folded to form a thin film to be carried conveniently.

A head-mounted display (HMD) system includes an optical arrangement, a first image panel, a second image panel, and a central image panel located between the first and second image panels. The optical arrangement is reconfigurable between a first position and a second position that maintains first and second optical pathways of the first and second image panels, and the HMD system has a different form factor when the optical arrangement is in the second position as compared to the first position. The optical arrangement includes at least one segmented optical component, wherein segments of the segmented optical component are moveable relative to each other to reconfigure the optical arrangement between the first position and the second position. The segmented optical component may include one more lens assemblies, each with multiple lens segments that are rotatable relative to each other about a hinge structure.

A head-mounted display apparatus includes: a first body formed in the shape of a diving mask to cover up a user's nose and eyes and having vision holes formed at a position where user's eyes are located; a first external body extending forward from the rear end of the first body and surrounding the side of the first body; a second body having a cross section in the shape of inverted with its front face opened and with a lens fixed to a rear face corresponding to the vision hole; and a second external body extending rearward from a front end of the second body to surround the side of the second body and having a terminal mounted on the front end thereof,

A virtual reality viewer may be integrated with printed materials, such as pamphlets, flyers, magazines, or books. A user may be able to review the printed material regarding the advertised products or services and then activate a virtual reality scene on an electronic display, such as the user's mobile device, that provides the user with more information regarding the products or services. The virtual reality viewer may be attached to pages in the printed materials and constructed in a manner such that the viewer pops up when the pages are opened. The user may place a mobile device in the viewer and/or access an integrated display to view a virtual reality scene related to content in the printed materials.

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.
