A virtual reality viewer reconfigured from a standard post card such that the post card is transformed into a three dimensional body and attached to a cell phone to view a three dimensional scene . The folds on the outside of the post card enable the post card to form the virtual reality viewer. The post card also includes a set of lenses and a locking mechanism to hold the viewer onto the cell phone.

A stereoscopic viewing apparatus for use with a SmartPhone including a pair of lenses and a viewer body preferably fabricated at low cost from a single paper sheet. The sheet is provided with a pair of fold lines which define first and second sheet segments separated by a lens mounting segment. The lens mounting segment defines a pair of left and right lens openings for receiving the respective lenses, with the mounting segment further defining features that secure the lenses in place in the lens openings. When in an operating mode, the first and second sheet segments function to position the lenses appropriately for viewing stereoscopic images on a SmartPhone screen, with the viewer being capable of being folded into a compact state for shipping or storage.

To provide a stereo viewer and/or a stereo view finder that enables a stereo image displayed on an electronic display to be easily visualized and to enhance portability so as to be easily and conveniently carried when photographing and viewing the stereo image outside. There is provided a stereo viewer/stereo view finder (1) including a foldable light shielding hood (10) attached on a liquid crystal display (D), and a magnifying lens (20) including a pair of lenses (21R, 21L) for viewing stereo images (SR, SL) and a lens folder (22), the magnifying lens being attached to a front inner wall surface (11a) of the light shielding hood (10) by way of a hinge (23) and being developable to be parallel to the liquid crystal display (D).

A stereoscopic image viewer comprises a frame to be physically coupled to a handheld electronic device. The frame comprises a face plate having a pair of lens sockets with a pair of lenses, and a pair of side arms with a pair of slots to receive the handheld electronic device. The lenses can be coupled in the sockets by twist-to-lock couplings. A forehead pad comprising a squat dome is disposed on the face plate.

An accessory includes a lens frame and a pair of lenses. The lens frame includes a spacer plate, a lens plate and a pair of foldable plates. The spacer plate is coupled to a portable device. The lens plate is flexibly connected to the spacer plate. The pair of foldable plates are flexibly connected between the spacer plate and the lens plate. The pair of foldable plates are unfolded in using state so the lens plate is opened in a preset angle relative to the spacer plate. The pair of foldable plates are folded in folding state so the spacer plate and the lens plate overlap each other. The pair of lenses are disposed on the lens plate, and positioned in front of a display of the portable device in using state. A lens system including aforesaid portable device, the lens frame and the pair of lenses is also provided.

A portable virtual reality glasses for accommodating an electronic device is provided. The portable virtual reality glasses includes a frame and a spectacle frame assembly assembled with optical lens. The frame includes a first cover, a second cover, a first side plate body, and a second side plate body. The first cover, the second cover, the first side plate body, and the second side plate body are connected with each other to define an accommodation space. By relatively moving the first side plate body and the second side plate body with respect to the first cover and the second cover, the frame can be transformed to either an extended state or a folded state, to change a volume of the accommodation space. The spectacle frame assembly is connected with the frame, for moving relative to the accommodation space of the frame.

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 portion in which a detachable panel 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 viewer is of a unitary construction in which the panels of the body portion and the panels of the viewing portion are die cut from a single piece of material and folded along fold lines to form the viewer.
