Three-Dimensional Viewer
Field of the Invention

The invention relates to 3D viewers for electronic devices.

Background
Smartphones and other portable devices with screens have been used for some
time to display two-
dimensional (2D) images and video to a user. Larger devices having a back-lit
such as televisions and
computers also project 2D images into the eyes of a user. A significant
shortcoming of 2D entertainment
is that it pales in experience with our 3D view on the real world. Therefore
there have been attempts in
the art to produce 3D projected images.

3D televisions have been on the market for some time however require glasses,
which block alternating
eyes in synchronicity with the television, to show slightly different views to
each eye to provide a .
perception of depth. However, the glasses are cumbersome and uncomfortable to
wear, and each set of
glasses may be used by only one user at a time.

Therefore there is a need for 3D projection technologies that provide a
perception of three dimensions
to users without the need for cumbersome glasses and complicated synchronizing
systems.

Summary
Disclosed is a viewer providing a 3D effect comprising a housing containing a
viewing area and having a
viewing aperture, a back-lit screen for displaying images, the screen mounted
in the housing and facing
into the viewing area, the screen divided into two or more screen portions,
and two or more translucent
planes, stacked in relation to the viewing aperture, each plane mounted within
the viewing area
adjacent to a screen portion and angled to project one or more images from the
screen portion out
through the viewing aperture, wherein images on planes closer to the viewing
aperture appear
superimposed over images on planes further from the viewing aperture.

images on the planes for a 3D effect.

One embodiment further comprises a housing containing a viewing area and
having a viewing aperture.
In an embodiment the screen is divided into screen portions, wherein each
screen portion displays an
image for a particular plane. The screen may be removable. In a preferred
embodiment the screen is a
portable device screen and the portable device is removably mounted within the
housing.

The housing may have an opening opposite the viewing aperture to view images
on the one or more
planes plane superimposed over the environment. Further, the angle and
position of the planes may be
adjustable. The planes may be molded in the housing and may be transparent.

Further disclosed is a three-dimensional viewer comprising a screen for
displaying images, the screen
divided into two or more screen portions, and a set of two or more planes and
projecting from the
screen, wherein each screen portion corresponds to a particular plane and the
image from the screen
portion is partially reflected in the corresponding plane.

In one embodiment the planes are translucent. The planes may be transparent.
The screen may be a
portable device screen. The planes may be symmetrical or asymmetrical.

Detailed Description

The three-dimensional (3D) viewer is an enclosure that fits around a display
system, such as that of a
portable smartphone or tablet having a screen, or a non-portable device having
a screen, and produces
an image that has perceived depth for a user looking in. In one embodiment it
produces an image that
appears to float in space. The viewer is intended but not limited to use with
portable devices such as
smart phones, PDA's, tablets and other portable electronics (portable image
electronics) that produce a
viewable image through a back lit screen. Furthermore, an image producing
electronics could by design,
incorporate the device as a permanent feature.

With reference to Figure 1, a stacked configuration of the viewer is shown. In
one embodiment the
viewer 2 has a housing 10 that blocks all or most ambient light from entering
the viewing area 12, which
is enclosed and defined by the housing 10, with the exception of a viewing
aperture 14 in the front of
the viewer, through which a user looks to view the image. The housing 10 may
be any shape, but in

particular, when used for gaming, may take the shape of an object a game
player interacts with, such as
a gun, a motorcycle console, a race car steering wheel and console. The
housing 10 is frequently an
opaque and robust material such as plastic for blocking light and for
protecting the viewing area 12,
however in certain applications the housing 10 is partially transparent. The
housing does not flex such
3


CA 02796304 2012-11-13

that it holds the contents of the viewing area 12 in a fixed dimensional
relationship. Preferably the
viewer is made from plastic, however components such as the housing 10 may be
made from a number
of other materials, including metal, wood or other materials known in the art,
and planes 15 within the
housing 10 may be glass. The housing 10 has a ceiling 11 therein and walls 13
at the side and rear,
blocking ambient light and preventing viewing out of the viewer. The interior
of the housing 10,
including ceiling 11 and walls 13, is absorbent of light so as to minimize
reflected light, images and other
similar interference. in an embodiment, the housing 10 may have an opening
opposite the viewing
aperture 14 so that the viewer may view through the viewing area and out into
the environment, to see
an image in the viewing area 12 superimposed over the environment, to provide
a 3D effect. In this
embodiment there is no rear wall 13 (not shown) to the housing 10. In an
embodiment, the housing 10
is unnecessary and the planes 15 may be positioned on their own over the
screen 22, the images
viewable by the user on the planes 15 themselves, from practically any angle.
Without a housing they
may employ a frame to hold the planes 15 in position relative to one another.
Without the housing
blocking ambient light the image may be difficult to see unless in low-light
conditions.

With reference to Figures 1 and 2 the housing contains the viewing area having
one or more inclined
planes 15 (three planes 15a, 15b and 15c in this embodiment) therein, and a
device 20 having a back-lit
screen 22 facing into the viewing area 12. The housing 10 encloses the
inclined planes 15, which in one
embodiment are fixed into the walls 13 and ceiling 11 of the housing such that
they remain fixed relative
to one another and the back-lit screen 22. The screen 22 may be mounted above,
below or to the side of
the viewing area 12, and the planes 15 are mounted adjacent to the screen 22,
so as best to receive the
light transmitted from the screen. They may be mounted within grooves cut into
the walls 13 and ceiling
11, molded into position or held by means of mounting brackets, the use of
which is known in the art. In
another embodiment the planes are movable for angle and position, projecting
through the housing and
adjustable from the outside or adjustable within once the housing is opened.
The planes 15 are in a
stacked relationship with one another, that is they are in front of one
another with reference to the
viewing aperture 14, such that when a user views through the viewing aperture
14, he or she sees
through the multitude of planes 15, and images they carry are therefore
superimposed over one
another. In an embodiment, the planes 15 are user adjustable, and may be
constrained in a fixed
position relative to each other and the screen 22. The inclined planes 15 are
capable of reflecting light,
and may be transparent, translucent, and in one embodiment when a multiplicity
of planes are used the
plane that is located furthest from the viewing point of the user could be,
but does not necessarily have
to be, opaque. In a preferred embodiment the planes are translucent.
Considering clear glass transmits
4


CA 02796304 2012-11-13

only about 80% of visible light, clear glass is also considered translucent
for the purposes of this
disclosure. The screen 22 is divided into screen portions 22a - 22c, wherein
each screen portion 22a -
22c displays an image for a particular plane 15a - 15c. The screen 22 may be
fixed within the housing or
may be removable, and in a preferred embodiment the screen 22 used is that of
a portable device such
as a smartphone or table computer, which is inserted into the housing 10 and
removably secured there.
In one embodiment the housing 10 is adjustable for different screen sizes and
contains markers to align
the particular screen correctly and the screen 22 may be removably secured
within the housing 10. In
one embodiment a screen controller (not shown) splits a single screen image
into at least two images
for display on two or more screen portions corresponding to the two or more
planes, to provide a 3D
effect. The screen controller (not shown) may be implemented in software,
firmware or hardware.

The result of the above configuration is that content on the screen of the
image electronics are reflected
off the inclined planes 15 towards a user or viewer. As the planes 15 are
transparent or translucent the
viewer is able to see the image on the inclined plane closest to them as well
as being able to see images
that are reflected off of each subsequent translucent or transparent plane
further away from them.
Regarding the translucent planes, some light is reflected to the eyes of the
user following light path Z,
and some light remains on the plane and is visible there, potentially from any
angle. Transparent planes
reflect the image due to the inclination of the plane and the phase change
from air to solid material.
Removal of the ambient light greatly increases visibility of the image. Since
the planes are translucent,
they project a reflection of the screen image 22 to the viewer, however the
user can see through each
one to superimpose that image with the "layer" behind. The result is a 2D
image on each plane that
produces a composite image that appears 3D due to layering that is achieved by
using translucent or
transparent planes, wherein the viewer's eye recognizes that the composite
image has depth.
Translucent Even a single plane provides an image that appears to be floating
in air, within the dark void
of the enclosed viewing area 12 or particularly where the viewing area 12 can
be seen through to the
environment, so that the floating image is superimposed on the environment.

With reference to Figures 1 to 3, the inclined planes 15a - c are spaced
relative to the screen portions
22a - c and have an angle A, B, C such that they reflect the images from the
screen portions out the
viewing aperture 14 and into the eyes of a user. The light path from the
screen 22a - c to the respective
plane 15a - c, and on to the eyes of the user, is shown in stippled lines Z.
The angle A, B, C depends on

the height of the planes 15a - c and size of each of the screen portions or
"slices", and may be the same
between planed 15a - c or may differ for each plane 1Sa - c depending on the
configuration of the
5


CA 02796304 2012-11-13

viewer. The screen may be divided into a multitude of parts, typically
corresponding to the number of
planes 15. The plane 1S angle may range from 20 to 80 degrees; however a
preferred range is 30 - 60
degrees, which results in a reasonable number of screen slices and a
reasonable height of the viewing
aperture 14. In the embodiment shown, the angle is approximately 45 degrees.
The number of screen
slices is unlimited, only constrained by the thickness of each plane 15 and
the length of the screen 22. In
multi-plane embodiments every plane angle need not be the same, and each plane
may be at a different
angle. The more slices, the smaller the screen or the more obtuse the angle
needs to be in order to fit
the constraints of the screen 22.

For example, in the embodiment shown in Figures 1 - 3, a three-plane viewer
would divide the screen
22 into thirds, with an image showing on each third. Each third is, in turn,
projected into the eyes of a
viewer by means of i) the translucence of the planes, and ii) the angle of the
planes oriented to reflect
the image out through the aperture 14. Due to the translucence or transparency
of each plane 15, the
user partially sees through the planes so that the images superimpose on one
another, while
maintaining their relative depth, to provide the perception of a three-
dimensional image. The depth
would be limited to one of three depths, wherein the planes 15 appear. The
image of plane 15a will be
perceived as in front of that of plane 15b, and the image of plane 15c will
appear behind that of plane
15b. The viewer has the surprising benefit of producing 3D images having depth
that may be viewed
with the naked eye, without the need for special glasses. Images may be
rapidly sequential so as to
produce the perception of movement, in the case of video images for example.

As an example of a use, the housing 10 is in the form of a motorcycle console
with handlebars, for
playing a motorcycle game. The handlebars have controls, such as throttle and
brake that are
communicated to a smartphone, as well as movement of the console from side-to-
side, which is
communicated to the smartphone by means of the smartphone's accelerometer. The
smartphone is
inserted face-up against the bottom of the inside of the housing 10. The
housing 10 is hinged at the back
and closed over the smartphone so as to retain the smartphone therein, such
that the planes 15 are
adjacent to the screen 22. The gamer looks through the viewing aperture 14.
The image on plane 15a is
closest to the viewer and represents the foreground, so may show a competing
rider directly in front of
the player's motorcycle. The image on plane 15b represents the midground, so a
number of the
motorcycles that are farther ahead, as well as signs on the road. The furthest
image on plane 15c
represents the background, such as the grandstands and the upcoming curves.

CA 02796304 2012-11-13

In another embodiment, the smartphone is similarly enclosed in the housing,
however the housing has
an opening opposite the viewing aperture 14 so the gamer may see into the
environment, through the
planes 15. The housing may be shaped like a gun. Again, the planes show
foreground in plane 15a,
midground in plane 15b, and background in plane 15c, with the background
further supplemented by
the environment, like a forest or marsh, that the gamer is physically playing
in. The foreground depicts
damage when the gamer is hit, or enemies that are very near. The midground
shows enemies further
away. The background shows far objects in the distance that provide context.

With reference to Figures 4 and 5, a pyramidal configuration is shown. This
embodiment enables
projection of an image that appears to float in space within the viewing area
12 defined by the planes
35a, 35b, 35c, 35d. The viewer is located at a distance relative to the screen
of the electronics such that
one or more users can view the reflected 3D image from a variety of locations
around the viewer. A
housing (not shown), if used, is adapted to hold a pyramidal set of planes
35a, 35b, 35c, 35d over the
screen, either directly adjacent to the screen or at a small distance, such as
a few centimeters or inches,
therefrom. In another embodiment, a simple plastic or wire frame (not shown)
holds the pyramidal
plane set 35 in position above the screen 22. The planes 35 define a viewing
area 12. In this
embodiment the set of planes 35a, 35b, 35c, 35d forms a square-based inverse
truncated pyramid,
having four truncated triangular planes 35a, 35b, 35c and 35d, with the flat
apex 38 against the screen
22, and wherein the base is absent. The apex 38 may be used for supporting the
planes 35a, 35b, 35c,
35d on the screen 22. Each triangular plane 35a, 35b, 35c and 35d displays a
triangular portion of the
screen 22 directly below it. In other embodiments the pyramid may be
triangular-based or have a
plurality of planes such as pentagon-based or hexagon-based pyramid would (not
shown).

The screen 22 is divided into 4 triangular portions or "slices", 22a, 22b,
22c, and 22d, each showing an
image that is meant to be displayed in the plane 35a, 35b, 35c, 35d,
respectively, that is above it. For
example, the images may show different sides of a figure so that the figure
appears to be 3D, or may
show the same image which will appear to hover in space. Accordingly, plane
35a displays or partially
reflects screen portion 22a, plane 35b displays screen portion 22b, plane 35c
displays screen portion 22c
and so on. Based on the translucent character of the plane, the combination of
the images is perceived
by the user, who may be at almost any angle from the viewer, as floating in
the air within the pyramid. A
different view may be shown on each plane, to show the front, left side, rear,
and right side of an object

for example. The illusion of depth is created due of the lack of other
features in the viewing area that
would provide a frame of reference, the image appears truly like a hologram
suspended in air. Although
7


CA 02796304 2012-11-13

the set of planes 35a, 35b, 35c, 35d need not be centred over the screen 22,
it must be aligned above
the screen in accordance with the screen slices 22a - d, so as to display the
images correctly. The planes
35 a-d may not all be the same size and orientation, and asymmetrical planes
will require asymmetrical
screen slices 22a-d that correspond with the orientation of the planes 35 a -
d. Each screen portion 22 a
- 22d corresponds to a particular plane and the image from the screen portion
is partially reflected in
the corresponding plane, for example the image from screen portion 22b is
reflected in plane 35b. The
viewer produces the surprising result that a 3D image appears to be floating
in air, somewhat like a
hologram, and this image can be in motion when the screen is showing video
images. This embodiment
is most useful for hologram-type images or multiplayer games wherein, for
example, each player
receives information from a plane to control his "player" in the game.

With reference to Figures 6 and 7, a V-configuration of the 3D viewer is
shown. The two planes 37a and
37b project from the screen 22, which is divided into two screen portions 22a
and 22b. Optionally, a flat
base 39 helps to hold the planes 37a, 37b on top of the screen 22, wherein
planes 37a and 37b are
integrally connected to base 39. In other embodiments, a frame (not shown)
around the planes 37a and
37b hold the planes in position above the screen 22. The images are projected
from the back-lit screen
portions 22a, 22b of the device 20, onto the corresponding planes 37a, 37b
above, such that images are
partially reflected from the translucent plane 37a, 37b following light path
Y, Z, and are partially
absorbed and emanated from the planes 37a, 37b, such that the images are
visible from any angle. As a
result, an image appears to float in space, providing the perception of a 3D
image. This embodiment is
useful for multi-player games, particularly for two players, wherein they sit
opposite to one another and
each one uses a screen to receive information.

To produce an effective result the viewer is used in conjunction with software
on the electronic device
that divides the image producing area into segments that are sized
proportionate to, and located
relative to, each inclined plane such that the image produced in that screen
segment is only reflected by
the intended plane. When the viewer has multiple planes not all planes or
segments of the image
producing screen need to be in use at the same time, or at all. When the
viewer has multiple parallel
planes the image on the screen segment closest to the user will be reflect on
the inclined plane 15
closest to the user and hence this image will appear closest to the user. The
image produced on each
subsequent screen portion 22a, 22b etc. further away from the user will
reflect from its appropriate
inclined plane 15 and appear at a distance further away from the user. Because
the images from the
8


CA 02796304 2012-11-13

inclined planes 15 located further away from the user are visible through each
inclined plane 15 that is
closer to the user this creates a depth of image resulting in a 3D effect.

The embodiment of the viewer that is intended to be viewed from multiple
viewing angles by multiple
users produces a limited depth view because the inclined planes are not
parallel to each other. The
image reflected from the plane appears to be "floating" in space.

A method of using the viewer is disclosed, First, in step 50 the user inserts
or positions the portable
device within, on, or under the viewer and secures it there. Due to the
variety of shapes and sizes of
portable image producing electronics the fixture in the viewer that constrains
the electronics is
adjustable with directions and/or markings to indicate the correct positioning
of the most popular
electronics. Second, in step 52, showing an image on at least 2 portions of
the device's screen. Third, in
step 54 displaying the image on corresponding planes located adjacent to the
two or more portions. As a
fourth step 56, viewing the 3D image
