Crewmembers could also learn by using simulations to acquire new skills or execute training drills. They could simulate surgery, flight, and engine repairs in a truly realistic environment.
The holodeck is still science fiction, but last year researchers took the first, confident steps towards its realisation with the Coherent project. This EU-funded research project, developed a commercial, true 3-D display that could one day be called Holodeck version 1.0. It is called HoloVizio.Innovation intensive
"The aim of the COHERENT project was to create a new networked holographic audio-visual platform to support real-time collaborative 3-D interaction between geographically distributed teams," explains Akos Demeter, spokesperson for the project.
Two applications drove the design of the basic networked audiovisual components – a collaborative visualisation system for the medical sector and a collaborative design review system for the automotive industry.
The researchers based the display component on innovative holographic techniques that can present, at natural human interaction scale, realistic animated 3-D images simultaneously to an unlimited number of freely moving viewers.
The COMEDIA application, for example, uses raw data from medical imaging devices to create 3-D models of anatomy. The development, led by Coherent partner CRS4 Visual Computing, demonstrated the system to 50 clinicians in Italy.
"The strength of the COMEDIA system is related to the collaboration, discussion and evaluation of clinical cases, since it provides users with an immediate 3-D understanding of the anatomy shown," explains Demeter.
COMEDIA led to the 'Holo-Heart' series of seminars last year.Art's hidden secrets
It is impossible to see this by standing in front of the statue, because of its height and the position of the left forearm. But it becomes clear when viewed through the COHERENT system, and theorists posit that Michelangelo wanted to present two different faces of the same character.
Coherent also led to the development of the COLLAUDA application for collaborative automotive design. The application, developed with CS Systemes d’Information and Peugeot in France, led to a series of demonstrations to potential end users.
The demonstration led to a new project collaboration, named ARIVA, which starts in June 2008.Oil exploration
In all, the team developed useful applications for a leading edge, emergent technology, explored excellent commercial opportunities and perfected holographic and allied systems for real-world use. The research also stimulated enormous interest in the area and prompted a wave of activity in the sector. But history, perhaps, will remember the Coherent project as the precursor to a real world holodeck.
The project received funding from the EU's Sixth Framework Programme for research.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
