Heliodisplay
Helio Display Report.doc (Size: 589 KB / Downloads: 102) ABSTRACT The Heliodisplay is a free-space display developed by IO2 Technology. A projector is focused onto a layer of mist in mid-air, resulting in a two-dimensional display that appears to float. This is similar in principle to the cinematic technique of rear projection. 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. Looking directly at the display, one would also be looking into the projector's light source. The necessity of an oblique viewing angle (to avoid looking into the projector's light source) may be a disadvantage. Heliodisplay can work as a free-space touch screen when connected to a PC by a USB cable. A PC sees the Heliodisplay as a pointing device, like a mouse. With the supplied software installed, one can use a finger, pen, or another object as cursor control and navigate or interact with simple content. The mist is formed by a series of metal plates, and the original Heliodisplay could run for several hours on one liter of tap water. 2008 model Heliodisplays use 80 ml to 120 ml of water per hour, depending on screen size and user settings, and can be built with any size water tank. The Heliodisplay was invented by Chad Dyner, who built it as a five-inch prototype in his apartment before patenting the free-space display technology, and founding IO2 Technology LLC to further develop the product. The Heliodisplay is sold directly worldwide by IO2 Technology. INTRODUCTION Heliodisplay is a hi-tech projector that displays pictures in the air. The is a free-space display developed by IO2 Technology. A projector is focused onto a layer of mist in mid-air, resulting in a two-dimensional display that appears to float.

A PC sees the Heliodisplay as a pointing device, like a mouse. With the supplied software installed, one can use a finger, pen, or another object as cursor control and navigate or interact with simple content. Heliodisplay is a patented projection system designed to project video, products, information, ETC. The Heliodisplay is a free-space display developed by IO2 Technology. The Heliodisplay was invented by Chad Dyner, who built it as a five-inch prototype in his air apartment before patenting the free-space display technology, and founding IO2 Technology LLC to further develop the product. A projector is focused onto a layer of mist in mid-air, resulting in a two-dimensional display that appears to float. This is similar in principle to the cinematic technique of rear projection. 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 Heliodisplay transforms water into a unique screen of fine vapour, suspended in mid-air to create a nearly invisible screen into which any image can be projected. The display can create a true 3D hologram effect when the right content is used. Io2 Technology IO2 Technology today announced the release of the Heliodisplay M2, its revolutionary second-generation Heliodisplay free-space display. Like the first-generation Heliodisplay M1, the Heliodisplay M2 displays high-resolution, full-color video in thin air, without a physical screen. The M2 features a screen area 87 percent larger than that of the M1, and boasts many other improvements allowing for superior images. "Market reaction to the first-generation system has been extremely positive, and based on our evolving advancements, the M2 is the next step in our product line," said Chad Dyner, the inventor of the technology used in the Heliodisplay. With the M2, the Heliodisplay extends its usefulness to the marketing, retail and trade-show industries. "Our customers have been excited about getting a screen area that’s almost double in size from the last version," said IO2 Technology operational manager Jay Fields. With its new design, the M2 can be installed under a table, to have video suddenly appear in front of the viewer floating in the air. Heliodisplay & its Principle The Heliodisplay is an interactive planar display. Though the image it projects appears much like a hologram, its inventors claim that it doesn't use holographic technology, though it does use rear projection (not lasers as originally reported) to project its image. It does not require any screen or substrate other than air to project its image, but it does eject a water-based vapour curtain for the image to be projected upon. The curtain is produced using similar ultrasonic technology as used in foggers and comprises a number of columns of fog. This curtain is sandwiched between curtains of clean air to create an acceptable screen. Heliodisplay moves through a dozen metal plates and then comes out again. (The exact details of its workings are unknown, pending patent applications.)It works as a kind of floating touch screen, making it possible to manipulate images projected in air with your fingers, and can be connected to a computer using a standard VGA connection. It can also connect with a TV or DVD by a standard RGB video cable. Though due to the turbulent nature of the curtain, not currently suitable as a workstation. The Heliodisplays are interactive, allowing a finger or hand to move images around in the air as if one were grabbing a virtual object. Displaying Data in Thin Air The first permanent prototype was installed in the Vapriikki museum in Tampere and has since been loaned for use in France. Fog Screen is renting some devices and expects to begin sales soon. Rakkolainen said, this project started as a wild idea. The researchers formed Fog Screen Inc. last year and are currently marketing the device. Although Heliodisplay and Fog Screen are interesting, it remains to be seen if new techniques represent the latest approach to display technology: doing away with the screen. While unlikely the replace the desktop computer monitor, these thin-air display could eventually be put use in product showrooms, museums, military training facilities, corporate conference rooms, trade fairs, theme parks, and advertisements. Chad Dyner, a graduate student at the Massachusetts Institute of Technology and chief executive officer for IO2 Technologies, has invented the Heliodisplay, which condenses the air above a video projector. The device then projects an image onto the condensed air.

Heliodisplay
Heliodisplay.pdf (Size: 114.99 KB / Downloads: 72) Heliodisplay is an interactive free-space display that projects images or streaming videos onto a layer of mist in mid air, resulting in a two-dimensional display. Heliodisplay can work as a free-space touch screen. With the optical laser-tracking system a user can interact with the displayed images. DSR has developed proof of concept and prototyped the Heliodisplay controller. Microchip PIC was used as the controller and the system had Inductive and Resistive loads up to 100W, PLED display, Ultrasound proximity detector, USB interface, SMPS, Audio amplifier, Real-time clock, humidity and level sensors and interfaces to various audio/video inputs. 3D Goggles Stereoscopy (three-dimensional) imaging is a technique capable of viewing three-dimensional visual information by creating an illusion of depth in an image. The illusion of depth in a movie is created by presenting a slightly different image to each eye. The illusion is created by rapidly changing glasses from dark to clear thereby creating a different image to left eye and right eye. The glasses are implemented using a special LCD called Pi-Cells. These glasses are developed to watch 3-D movies or play 3-D games at home. Interactive White Board Interactive whiteboards cost thousands of dollars which is too expensive for small businesses or schools. An alternate solution was designed to transform any white board into an interactive display system. The device consists of a camera and connects to the PC through USB. The projected image of the computer on the white screen can be interacted using a light pen. The device tracks the light pen and sends the position of the pen to the application program. This device could use to transform any surface into an interactive display and also make an LCD screen on a laptop touch screen capable. Street Light control system The street light control system was developed to control and monitor the street light based on street numbers. The application operates in setup and display modes. The system controls the lighting system based on the time setup to turn ON and turn OFF the lights. The system changes its turn ON and OFF time based on the season. The monitoring system on the Linux desktop displays the current status of the street lights. The controller is connected to the PC through parallel port. |
