Telepresence system “sets new standard”

Slightly gushing and over the top presentation, but an extremely impressive technology none the less. This post from InAVate magazine

Digital Video Enterprises has unveiled a telepresence system that not only simulates face-to-face meetings but can display nine foot wide 3D images that appear to float in mid-air. The Immersion Room solution scooped a Frost & Sullivan Telepresence Product award.

The meeting experience displays HD 3D holographic images of people for realistic videoconferencing.
"The Award was determined after a thorough review of the competing telepresence solutions and the DVE Immersion Room clearly has set a new standard for the potential realism of telepresence communication," said Paul Waadevig, principal consultant at Frost and Sullivan. "The whole point of telepresence is to simulate a meeting where people forget about technology and get down to business. The Immersion Room is a breakthrough in simulating face-to-face meetings that, literally, makes the users forget they are not all in the same room."

Immersion Room enables life-size images of people seen standing and walking about in the 3D physical space of the meeting room. Furthermore, the Room displays nine foot wide volumetric 3D images appearing to float in mid-air. The effect does not require special glasses.
The DVE Immersion Room is based on an extensive patent portfolio of augmented reality telepresence that places real-time images of people inside the middle of the room. The inclusion of hidden cameras that aim through the image are designed to create natural eye contact.

Touchable holography becomes a reality

September 20, 2009

Japanese researchers at the University of Tokyo have developed a touchable holographic display that allows users to interact with a floating 3-dimensional image. Using a combination of Wii gesture recognition sensors and a ultrasound transmitter, the researchers were able to not only control a holographic object floating in space, but to give the user tactile feedback when they “touch” it.

3D display cube creates images in real-time

Japan’s National Institute of Information and Communications Technology has unveiled a new handheld, 3D communications tool. The gCubik, developed by the NICT earlier in the year, reproduces 3D images, inside a 10cm-per-side cube, that are viewable without special glasses. Now, the gCubik+i can generate the images in real-time allowing them to be manipulated using touchscreen panels and on-board motion sensors.

All the six faces of the cube display 3D images, allowing users to see the display from every possible direction. By adding special sensors, users can also interact with the inside images.

The gCubik was born out of a drive at NICT to develop 3D technology that does not require 3D glasses. The organisation said: "Our "gCubik", a cubic auto-stereoscopic display, which has been designed as a tool to support communication among multiple users, is a graspable display born from this new concept."

Each face of the display includes a touch panel. Speakers for posture and acceleration are included inside. Therefore, users can have simple interaction with the 3D images displayed. This now makes it possible to develop applications and begin discussions towards using the display as a communication tool.

The Institute hopes that, by allowing users to share 3D images instead of pictures, it can provide a new means for future communications. "We plan to propose a new interaction paradigm, and develop applications, for multi-user collaborative tasks that exploit the concept of ‘Graspable 3D Images’," the Institute said in a statement. "Furthermore, we plan to make the display which is wireless, even more compact and improve its image quality in preparation for commercial applications."

Each face of the display uses integral photography, which is one of the various methods to display 3D images without special glasses (auto-stereoscopic). When viewing a real scene, humans see a different image with each eye, which depends on the distance and the different position of the eyes (binocular parallax). When we move our heads, we see different images (motion parallax). These are some of clues on how humans perceive depth (3D). Integral photography uses a tightly packed micro convex lens array to record distinct ‘elemental’ images, and when these images are again viewed through the same micro-lens array, they reproduce the 3D integrated image of the scene with both binocular and motion parallax. The Institute’s system utilises the electronic integral photography which uses an LCD display, instead of the recorded photograph, to display the elemental images.

Integral photography makes use of the principle that convex lenses are designed so that parallel incoming light rays converge into its focal point. Conversely, all the ray lights coming from a light source at the focal point will come out of the lens as parallel rays in the direction of the line joining the light source with the lens principal point.

By arranging and displaying appropriate elemental images on the LCD pixels corresponding to each lens, each screen of the display functions as a window where different views of the scene can be observed depending of the viewing angle. By using integral photography (IP), horizontal and vertical motion parallax for 3D images can be observed without special glasses.

Besides, auto-stereoscopic displays using lenticular lenses are more widely known than the ones that use integral photography, but they only provide horizontal motion parallax, a subset of the parallax provided by IP.

‘3D Enabled’ Households By 2012, reports DailyDOOH

Interesting quote from Sarah Carroll, Director of Continuous Services, Futuresource Consulting in their recent research ‘Strategic Impact of 3D’ report on the 3D enabled home, she said “Consumers are starting to experience the new wave of 3D technologies at the cinema and through Digital Out of Home advertising, and it won’t be long before there’s a groundswell of demand for 3D within the home”

Bottom line Futuresource Consulting believe that by 2012 more than 10% of US and Japanese households will be ‘3D enabled’ and Western Europe won’t be far behind.

Now more than ever it seems that 3D is coming to the fore, with backing from all major sectors of the entertainment and consumer electronics industries.

3D movie production of course is intensifying and cinemas all over the world are investing in 3D technologies – feedback too, from audiences has been highly positive, with encouraging ticket sales.

Futuresource Consulting however believe that the ultimate goal is to bring 3D to the home. Their report reveals studios, consumer electronics companies, broadcasters, video game vendors and network operators are all poised to power 3D through the consumer diffusion curve.
