Virtual display for cars could reduce accidents

04.10.2004


Many accidents, especially at night, are caused by motorists having to take their eye off the road as they look down to see the car instruments. Head-up displays would be a solution, were they not so expensive and bulky. OEDIBUS has an innovative solution.
Driving at night is dangerous. Research shows that, although less than one third of all driving is done at night, over 50 per cent of the fatalities occur during this period. For pedestrians, 60 per cent of fatalities occur during the hours of darkness. Part of the reason is that drivers have to change the focus of their eyes and the direction of their gaze every time they look down at the instrument panel.

A head-up display (HUD) can improve the situation, by projecting a virtual image of the instruments along a direction closer to the driver’s gaze when looking ahead and at a focal point far away from the driver.


"Conventional HUDs project the image onto the car windscreen," says Piermario Repetto of Centro Richerce Fiat and OEDIBUS coordinator. "The problem with conventional displays is that they are expensive and occupy an unacceptably large volume, typically in a range from 3 to 5 litres, which is impractical for most car instrument clusters."

Part of the problem with the volume is that the windscreen projection system needs an optical chain, the size of which is difficult to reduce. "The OEDIBUS display chain is very small, and the whole system occupies less than 0.5 litres," adds Repetto. "We use holographic technology to couple the light into and out of the HUD combiner. Light propagates through the material of the combiner and a set of holographic diffraction gratings is used to relay the image from a state-of-the-art microdisplay to the driver’s eye."

"This HUD concept is a real breakthrough," Repetto says. "It’s a completely new way of making HUDs. It’s very comfortable for drivers, too; there are only limited restrictions on their viewing position. And because it produces a virtual image, drivers don’t have to change their focus when they look at the display panel mounted on top of the instrument cluster."

The HUD will be exhibited at the forthcoming IST 2004 conference, and plans are in place for putting the system into production. "Expect to have HUDs installed in cars from 2008 onwards," says Repetto.

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
