Hi-Tech projector that display pictures in the
air.
Works as a free space touch screen when
connected to PC.
Although it is also a two-dimensional display
that appears to float (3d when using 3d
content).
Similar in principle to the cinematic technique
of rear projection and can appear threedimensional whenMJRP University
using appropriate content.

HELIODISPLAY
A screen projector display
in 2d.
A support structure (i.e.
projection-screen) is used
for displaying a projected
image.

All video, images can
been seen in 3d, this
makes the image more
realistic than on a
projection screen.
No screen is required,
as the system itself
creates an invisible
screen in the air and
thus projects on that.

The Heliodisplay was invented by Mr. Dyner.
He built it as a five-inch interactive prototype in
2001 before patenting the free-space display
technology.

The original system used a CMOS camera and
IR laser to track the position of a finger in midair and update the projected image to enable
the first of its kind co-located display with midair controller interface.
IO2 Technology commercialized the original
versions along with improvements.
The Heliodisplay is sold directly worldwide by
IO2 Technology with offices in California.

The device converts the imaging properties of
the air so that the air is taken in, converted
instantaneously, and then re-ejected out.
The system thus creates a dynamic, non solid
particle cloud by ejecting atomized condensate
present in the surrounding air.

Now the projector projects the given input on
the virtual screen formed.
It can be considered as a touch screen on which
the elements of the image displayed can be
moved around with a fingertip.
The image can still be moved with a fingertip,
but it floats unsupported above a quietly
whirring gray box that is connected to a laptop
computer.

Device is light weight and can be converted into a
furniture
Nothing is added to air. Nothing affects air quality
projected images and video are two-dimensional,
but appear 3D since there is no physical depth
reference
Heliodisplay does not create fog, so no electronic
devices in the room are affected
Heliodisplay can be used in any country since it
works on 95-115 or 220-240 VAC
Heliodisplay, imagery can be seen up to 75 degrees
off aspect for a total viewing area of over 150
degrees
No special glasses required to see the display

Heliodisplay is very expensive
Viewing a Heliodisplay image in direct
sunlight is almost impossible
Screen is essentially air, so it can become
distorted with too much air movement in the
room

Heliodisplay has great potential and would be
ideal for collaborative work
Heliodisplay is still in the initial stages and the
flaws of cost and environment of positioning
will soon be overcome.
Several other thin air-displays are available but
Heliodisplay outclasses them, because of the
attention it draws and its maintainability, and
as a result it has more market value
Its various applications such as in advertising,
a board room etc suggests that its future scope
is very bright.
