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: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
