This can be used to find how the face will deform after plastic surgery.

The Heliodisplay or Fog Screen technology from IO2 Technologies can project computer-based images onto thin particles of moisture. To showcase these various interaction technologies, we’ve developed a number of demo applications that explore many different interface possibilities.

Conventional displays have the benefit of being enclosed in a solid frame or case with lights shining directly towards the audience. Heliodisplay images are not holographic although they are free-space, employing a rear projection system in which images are captured onto a nearly invisible plane of transformed air.

In late helidisplay, a small company from the San Francisco Bay Area demonstrated a unique revolutionary display heliodisolay. 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 the parameters, ensuring an effective invisible to near-invisible screen for imaging. The Heliodisplay can be concealed i.

Build heilodisplay into a door jamb and have a walk through image or virtual privacy screen. 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: 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 heliodislay, yet large enough to provide an illuminated cloud for imaging.

The audience sees a floating mid-air image or video. However, these water screens may be large and look good if viewed from afar and on-axis.

In addition, the helildisplay projection redundancy mitigates occlusion from occurring, such as in the prior art, where a person standing between the projection source and the screen, blocks the image from being displayed.


Intersecting light rays from multiple sources further maximize illumination at the intended image location by localizing the sum of illumination from each projection source striking the particle cloud imaging location. Heliodisplay images appear 3D when viewed from more than a few feet away because there is no physical depth reference. Heliodisplay images are not holographic although they are free-space, employing a rear projection system in which images are captured onto a nearly invisible plane of transformed air.

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

Though due to the turbulent nature of the curtain, not currently suitable as a workstation. Apparently, the Heliodisplay creates a particle cloud by passing the surrounding air through a heat pump, which in turn cools the air to a level below its dew point, where it condensates, and is then collected to create an artificial cloud.

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.

This curtain is sandwiched between curtains of clean air to create an acceptable screen. This microenvironment 37and particle cloud 5 characteristics can be continuously optimized to compensate for changing environmental conditions, in order to minimize cloud visibility, discussed in further detail below.

Dark background emphasizes the contrast of the image and is highly encouraged when designing a location to view the display. 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.

With the lightest of touches, users can grab and shuffle images around, zoom in and out to see the minutest of details, or simply wave their hands over an image to make it come alive on screens as large as inches or centimetres.

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

However, that is an option that we can use, with the Heliodisplay or Fogscreen projector. This curtain is sandwiched between curtains of clean air to create an acceptable screen. The result is a thin, stable sheet of fog, heliodjsplay between two layers of air, on which an image can be projected and even walked through.

Particle cloud delivery device 4 ejects the microscopic particle cloud material locally re-humidifying the surrounding air 21creating an invisible to near-invisible particle cloud screen 5contained within a controlled microenvironment The curtain is heliodisplay seminar report using similar ultrasonic technology as used in foggers and comprises a number of columns of fog. A well-established method solving this constraint is by projection onto an invisible surface that inherently possesses a true spatially perceived image location; yet prior art method s rendered poor image fidelity.

The image is two-dimensional, can be seen from several angles, and be manipulated by hand. IO2 Technology is actually marketing the M2 to corporate customers who would use the device as a novel way to display the company’s logo or as a strikingly impressive advertising and promotional tool for exhibitions.

Heliodisplay provides a method and apparatus for generating true high-fidelity full color, high-resolution free-space video or still images with interactive capabilities. Tracking of the viewer is not necessary. The native resolution of the M2 is x though it can support up to xand the image can be viewed from as much as a degrees angle.

The M30 is the updated version of the M3, which fits into the current model numbering system, 30 designating the diagonal screen size. The M2i Heliodisplay can run for up to 10 hours on 2 litres of water and can display at resolutions of up to 1,x1, pixels. The device can be hung from the ceiling, placed on walls, on the floor, concealed within furniture such as a desk, and project images from all directions, allowing the image can be retracted when not in use.

Are you interested in this topic. This finds great application in criminology. The Heliodisplay only requires a standard power outlet and a video source i. The moisture film generated by the device captures the light from the projector to allow the images to take shape.
