Whats HELIODISPLAY ?
Heliodisplay is a technology used for displaying images in mid air.
9/16/2012
Contd
Results in a two-dimensional display that appears to float.
Similar to Conventional Rear Projection technique.
No physical screen required.
History
Developed by Chad Dyner, CEO of IO2 technologies.
In 2005 US patent office granted Dyner patent for his product (HELIODISPLAY)
Dyner found IO2 technologies to commercialize Heliodisplay.

Functional Overview
AIR
AIR
Contd Fine water vapour, suspended in mid air to create nearly invisible screen. This vapour curtain(screen) is sandwiched between layers of clean air to create an acceptable screen.

created by passing the surrounding air through a heat pump which in turn cools the air to a level below its dew point.
These particle cloud consists of individual micro-droplets, held together by surface tension.

Base Unit :
Converts the imaging properties of the air so that the air is taken in, converted instantaneously, and then re-ejected out. Creates a dynamic, non solid particle cloud by ejecting atomized condensate from air.
Projector :
Projector projects the given input on the newly created invisible screen. Similar to rear view projector. Higher quality image delivery output.

Extraction Device : Condensates the air. Extraction storage : The extracted condensate is stored in a storage vessel. : alters the condensate by mechanical, acoustical, electrical or chemical means, or a combination of these.

Particle cloud
9/16/2012
HELIOCAST :
Allows the image to serve as an input/output (I/O) device . Physical intrusion within the input detectable space of particle cloud , such as a user's finger, a stylus or another foreign object, is recognized as an input instruction. Reflected light scattered off the user's finger or other input means is captured by optical sensor.
Contd
Light beyond the frequency response bandwidth of the sensor is ignored or minimized, for better Noise immunity. The space coordinate of intrusion in space where the intrusion is lit by the functions as a mouse cursor, analogous to a virtual touch-screen.
controller reads and interprets the highlighted input data (coordinate) using blob recognition or gesture recognition software at Processor.

Connectors
PC Specifications : at least Pentium III 400MHZ 25MB free disk space Win2000/XP
Advantages
No screen is required to project images Light weight and can be used/converted
into a furniture
No chemicals are used. Nothing affects air quality projected. Two-dimensional, but gives 3D looks.

Contd
Heliodisplay does not create fog. It causes no odour in the air.
Contd
Heliodisplay system can be used in any country, regardless of voltage
standards.
Translucency is controlled by the Heliodisplay.

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.
Applications
Advertising/promotion

Heliodisplay is still in the initial stages and the flaws of cost and environment of positioning will soon be overcome. Its various applications such as in advertising, a board room etc suggests that its future scope is very bright.
