3. Introduction
 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 three-dimensional when using
appropriate content.

4. Heliodisplay and Screen Projector
Screen Projector
• A screen projector display in 2d.
• A support structure (i.e. projection-
screen) is used for displaying a
projected image.
Heliodisplay
• 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.

5. History
• 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.

6. History
• The original system used a CMOS camera and IR laser to track
the position of a finger in mid-air and update the projected
image to enable the first of its kind co-located display with
mid-air controller interface.
• IO2Technology commercialized the original versions along
with improvements.
• The Heliodisplay is sold directly worldwide by IO2Technology
with offices in California.

7. Principle
• This is similar in principle to the cinematic technique of rear
projection and can appear three-dimensional when using
appropriate content.

8. Working
• 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.

13. Development in Helodisplay
• MODEL M1
• MODEL M2
• MODEL M3 and M30
• MODEL M50 and M100
• Model L90
• P-SERIES
13

14. Specifications
• 1024 x 768 resolution, 16:9 or 4:3 aspect ratios.
• 2000:1 contrast ratio
• Supports all formats
• Projects any images that would be viewable on a computer screen
or television
• No specialized hardware or software
• 3D compatible
14

15. Advantages
• 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
• Translucency is controlled by the Heliodisplay
15

16. Disadvantages
• 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
16

17. Applications
• Advertising/promotion
• Video conferencing
• Virtual surgery and pre-operative planning
• Military training programs
• Gaming/artwork
• Engineering/architecture plans
• Build the Heliodisplay into furniture

18. Other display System with same principle
• Fog Screen: a display surface made out of a cloud
of water vapor diffused into the air as a very dry
fog.
• DNP Holo Screen
• Holoclear
• Depth Cube Z1024 display

19. Conclusion
• 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.
