The document presents an overview of the Heliodisplay, a high-tech air-based projection system that creates a floating screen for displaying images in both 2D and 3D. It discusses the technology's working principle, development, applications, and challenges, emphasizing its commercial availability and potential uses in various fields such as advertising and virtual conferencing. Despite its advantages, the Heliodisplay faces limitations such as high costs and difficulties with visibility in bright environments.

- 1. 2D & 3D Air based Projection system MJRP University Presented by: Shruti Bhardwaj VIII Sem Electronics & 1 Comm.
- 2. Contents Introduction Heliodisplay & screen Projector History Principal & Working Development in this field Negative Aspects Applications Conclusions References MJRP University 2
- 3. Hi-Tech projector that display pictures in the air. Works as a free space touch screen when connected to PC. Although it is also a two-dimensional display that appears to float (3d when using 3d content). Similar in principle to the cinematic technique of rear projection and can appear threedimensional whenMJRP University using appropriate content. 3
- 4. SCREEN PROJECTOR HELIODISPLAY A screen projector display in 2d. A support structure (i.e. projection-screen) is used for displaying a projected image. MJRP University All video, images can been seen in 3d, this makes the image more realistic than on a projection screen. No screen is required, as the system itself creates an invisible screen in the air and thus projects on that. 4
- 5. The Heliodisplay was invented by Mr. Dyner. He built it as a five-inch interactive prototype in 2001 before patenting the free-space display technology. MJRP University 5
- 6. The original system used a CMOS camera and IR laser to track the position of a finger in midair and update the projected image to enable the first of its kind co-located display with midair controller interface. IO2 Technology commercialized the original versions along with improvements. The Heliodisplay is sold directly worldwide by IO2 Technology with offices in California. MJRP University 6
- 7. This is similar in principle to the cinematic technique of rear projection and can appear three-dimensional when using appropriate content. MJRP University 7
- 8. 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. MJRP University 8
- 9. Now the projector projects the given input on the virtual screen formed. It can be considered as a touch screen on which the elements of the image displayed can be moved around with a fingertip. The image can still be moved with a fingertip, but it floats unsupported above a quietly whirring gray box that is connected to a laptop computer. MJRP University 9

- 14. 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 television No specialized hardware or software 3D compatible MJRP University 14
- 15. 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 MJRP University 15 Translucency is controlled by the Heliodisplay
- 16. 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 MJRP University 16
- 17. Advertising/promotion Video conferencing Virtual surgery and pre-operative planning Military training programs Gaming/artwork Engineering/architecture plans Build the Heliodisplay into furniture MJRP University 17
- 18. Fog Screen: a display surface made out of a cloud of water vapor diffused into the air as a very dry fog. DNP Holo Screen Holoclear Depth Cube Z1024 display MJRP University 18
- 19. Heliodisplay has great potential and would be ideal for collaborative work Heliodisplay 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.
