Natural warning sounds may be the future in airplanes and perhaps in cars as well. A “slurp” when fuel is low works better than a monotonous beeping sound. In a dissertation at The Royal Institute of Technology (KTH) in Sweden, Pernilla Ulfvengren has studied how warning sounds function, how we associate sounds, and how new sounds can be designed.
In the cockpit of an airplane there are a large number of warning units. If something happens to the plane, some twenty alarms may go off simultaneously, with lights blinking and a number of different beeping sounds signaling at high volume levels. These alarms are necessary, of course, but they can also confuse the pilot when there are too many of them to keep straight and remember what each one means. This problem has been known for some time.
With this in mind, Pernilla Ulfvengren embarked upon her doctoral studies. Designing alarm systems is in the field of cognitive engineering, technological research adapted to how the brain apprehends different types of information. The design of computer interfaces is another area in which cognitive engineering plays a major role.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
