The dispersion is caused by turbulence and friction in the fog’s flow, which disrupts the desired smooth planar surface, causing projected points of light to streak into lines.

The system senses when your finger breaks through the infrared beams and interprets your movements in a way not dissimilar to a touch-sensitive screen — except there’s no screen. The Heliodisplay uses no additives or chemicals, only plain tap water you can also use distilled water, ionized yeliodisplay or demineralised water if desired. The particle cloud composition consists of a vast number of individual condensate spheres held together by surface tension with a mean diameter in the one to ten micron region, too small to be visible individually by a he,iodisplay, yet large enough to provide an illuminated cloud for imaging.

Viewing requires no special glasses. Dark environment is preferred. The interactive M2i version includes virtual touchscreen capability. External ambient conditions such as temperature, humidity, and ambient lighting are read by sensors 36and sent to controller 35which interpret the data and instruct particle cloud manufacturing system 3 to adjust semjnar parameters, ensuring an effective invisible to near-invisible screen for imaging.

In its preferred embodiment, this invention operates solely on a power source independent of a water source by produc ing its own particle cloud material.


Oxygen passing over one electrode and hydrogen over the other generates electricity to run the device, water for the cloud material and heat as a by-product. A more recent development is the FogScreen, which creates an image in midair by employing a large, non-turbulent airflow to protect the dry fog generated within from turbulence. Some projection systems changed the operating environment by over-saturating the surrounding ambient air with particulates, such as humidity or other ejected gases.

Uses no additives or chemicals. Conventional displays have the benefit of being enclosed in a solid frame or case with lights shining directly towards the audience. A few examples of these include stereoscopic imaging via shutter or polarized glasses, as well as auto-stereoscopic technologies composed of lenticular screens directing light from a conventional display, or real-imaging devices utilizing concave mirror arrangements. In the multisource embodiment, the directing of light from multiple sources onto the particle cloud ensures that a clear image is viewable from all around, providing continuous on-axis viewing.


However, that is an option that we can use, with the Heliodisplay or Fogscreen projector. The user can interact with floating images or video, and manipulate them as you could with a mouse, including clicking and dragging.

As dark areas of the image may appear invisible, the image may be more realistic than on a projection screen, although it is still not volumetric. The image generator 9comprises a means of displaying still or video data for projection, which may be a laser based means of directing or modulating light from any illumination source used to generate a still or video image.

No special glove or pointing device is required. Air comes into the device, is modified then ejected and illuminated to produce the image.

The interface uses a tracked wireless joystick to control a 3D cursor around the head, while buttons on the joystick trigger stretching or sculpting actions. Tracking of the viewer is not necessary.


The surface can be viewed from arbitrary viewpoints with proper eye accommodation since each point of light has a real origin in 3D. The image manipulation comes courtesy of a row of infrared light emitters positioned just in front of where the water vapour emerges.

The curtain is heliodisplay seminar report using similar ultrasonic technology as used in foggers and comprises a number of columns of fog. The coordinate in space where the intrusion is lit by the illumination source corresponds to an analogous two or three-dimensional location within a computer environment, such as in a graphic user interface GUI where the intrusion input 14 functions as a mouse cursor, analogous to a virtual touch-screen. More sophisticated displays present different left and right images for stereo separation effects, but in general focal length remains constant across the entire image.

The machine thus modifies the air above a video projector, creating a screen, which can display any kind of video.

Although the Heliodisplay uses lasers, the images are not holographic. Varying the projected illumination intensity and cloud density can further attenuate the image transparency and opacity, a function not possible with existing displays. The interactivity significantly expands the possibilities of the display.


The M2i helidisplay includes a proprietary system, called Heliocast, for interactively controlling the displayed image and drivers for a standard PC.


Heliodisplay – Engineering Seminar. It does not require any screen or substrate other than air to project its image, but it does eject a water-based vapour heliodisplay seminar report for the image to be projected upon.

The Heliodisplay is an heliodisplay seminar report by Chad Dyner, who built it as a 5-inch prototype in his apartment before founding IO2 technologies to further heliodisplay seminar report the product.

The on-axis imaging transmissivity of the cloud screen coupled with the multisource projection insure a clear image, regardless of the viewer’s position and compensates for any aberration caused by turbulent breakdown of the cloud.

The Heliodisplay connects to a computer at least: Heliodisplay projects computer-based images onto thin particles of moisture generated by a particulate emitting device.

Unfortunately, with the tragic proliferation of advertising these days, we are probably looking at a future world where all the space on the buildings is taken for billboards and other various projected ads.

A user can navigate the forest by using a tracked wireless joystick to control their velocity and direction. The development of this distinctive technology, dubbed Heliodisplay by its developer Chad Dyner, began early this decade after Dyner decided to trade a promising career as an architect to become an inventor. This curtain is sandwiched between curtains of clean air to create an acceptable screen. The airborne film of moisture generated by the device — the black box with the large slot pictured in the foreground — captures the light from the projector to allow the images to take shape.

Heliodisplay projections are suspended in thin air, so you will notice some waviness to the screen stability and the intensity and clarity of the image is subject to ambient light conditions and optimisation of display settings.

When you touch an image on the airborne interactive screen, the coordinates are forwarded to a PC as a double-click, emulating a graphics tablet or mouse. Just as you use a mouse to move the cursor on a traditional computer monitor, you can use your finger heliodisplay seminar report move the cursor around the Heliodisplay image see:
