By Bargi Abhinandan Sadanand 1MV07EC014 Contents Introduction Working Specifications Models Advantages and disadvantages Applications Other display systems Conclusion Introduction Heliodisplay is a technology used for displaying images in mid air. In the heliodisplay, a projector focuses the image onto a layer of mist in mid-air, resulting in a two-dimensional display that appears to float. Basic units 1. Base Unit 2. Projection Source 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 found invisible screen SENSOR ILLUMINATION FEEDBACK CONTROLLER INPUT AIR SINGLE IMAGE DELIVERY OPTICS FLOATING IMAGE (INPUT/OUTPUT) SINGLE IMAGE GENERATION GRAPHICS BOARD STORAGE MULTIDELIVERY OPTICS PARTICLE CLOUD MULTI-IMAGE GENERATION PARTICLE CLOUD DELIVERY DEVICE PARTICLE CLOUD MANUFACTURE CONTROLLER SENSOR STORAGE EXTRACTION DEVICE AIR PROCESSING UNIT EXTERNAL SOURCE Developments in heliodisplay MODEL M1 MODEL M2 MODEL M3 and M30 MODEL M50 and M100 Model L90 P-SERIES 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 televison No specialized hardware or software 3D compatible Advantages No screen to project images 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 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 Video conferencing Virtual surgery and pre-operative planning Military training programs Gaming/artwork Engineering/architecture plans Build the Heliodisplay into furniture Fogscreen Fogscreen is a display surface made out of a cloud of water vapor diffused into the air as a very dry fog LARGE TRANSLUCENT DISPLAYS dnpHolo Screen Holoclear Perspecta A real 3D image is generated by Perspecta display, which draws 2D images on a quickly rotating screen to fill the entire volume swept out by its path Depth Cube Z1024 display Conclusion Heliodisplay has great potential and would be ideal for collaborative work Heliodisplays 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.
