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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
