The only place that would not be taken is the spaces that people walk through. The image manipulation comes courtesy of a row of infrared light emitters positioned just in front of where the water vapour emerges.

The image is display into two-dimensional space i. Conventional displays have the benefit of being enclosed in a solid frame or case with lights shining directly towards the audience. 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 current version of the Heliodisplay projects a 22″ to 42″ depending on model diagonal image that floats above seminarr device. 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.

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. The Perspecta is an enclosed device with lower resolution but with the capability to display a full 3D image and video with almost no flickering or wavering effects. Uses no additives or chemicals. Applications for this technology are wide-ranging, since the displayed image is non-physical and therefore unobtrusive.

Perspecta is a true 3D display capable of showing a 3D object perceived when simply walking around the display; the M2 displays a 2D image in midair, creating the illusion of depth. Again, we are back with latest project ideas for Mechanical Engineering. Displaying an image using conventional projectors requires a non-transparent medium, typically screens, walls, or even water, but air, which is transparent, cannot be used.

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.

Heliodisplay – Engineering Seminar. 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. Light beyond the frequency response bandwidth of the sensor is ignored or minimized, diminishing background interference and recognizing only intentional input The Heliodisplay transforms ambient air using a proprietary multi-stage system of modifying the optical characteristics within a planar region in seinar polychromatic light is scattered on this surface such that the image appears visible to the viewer.

The 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 seeminar optimization of display settings. The Heliodisplay connects to a computer at least: 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.

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.

Air comes into the device, is modified then ejected and illuminated to produce the image. Nothing is added to the air so there isn’t any harmful gas or liquid emitted from the device. The screen is safe for human interaction and will not cause any harm of any kind. The focus and heliodisplqy intensity of the projected image can be controlled by changing some of the cloud’s properties, enabling a sharper and brighter image.

The new third-generation M3 version launched on February 28th Like any semonar projection system, the images are best seen within 70 degrees to either side. It does not require any ssminar or substrate other than heliodisolay to project its image, but it does eject a water-based vapour curtain for the image to be projected upon. Also, just like viewing any computer monitor or TV, viewing a Heliodisplay image in direct sunlight is almost impossible. This website is built heliodisplay seminar report the students and helildisplay for the students.


The dnp HoloScreen and the HoloClear displays make the screen practically transparent from the viewer’s point of view, showing only projected objects. Virtual Forest was modified to be used with the Heliodisplay to show how a first person style interfaces would feel, and to show off some advanced real-time rendering techniques on the novel display. 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 focus and controlled illumination intensity onto the overall cloud, allow the individual spheres to act as lenses, transmitting and focusing light at highest intensity on-axis, whereby the viewer views the image at its brightest and clearest.

The display can create a true 3D hologram effect when the right content seminra used. The curtain is heliodisplay seminar report using similar ultrasonic technology as used in foggers and comprises a number of columns of fog. Like any rear projection system, the images are best seen within 70 degrees to either side.

Viewing requires no special glasses. The surface can be viewed from arbitrary viewpoints with proper eye accommodation since each point of light has a real origin in 3D.

The darker the room, the better is the result. Though the image it projects appears much like a hologram, its sminar claim that it doesn’t use holographic technology, though it does use rear projection not lasers as originally reported to project its image. Dyner bought an ordinary digital projector, took it apart, and spent entire days trying to figure out a way to stop in midair the light coming from the projector without engaging a traditional screen.
