We look at a Gothic cathedral in a different way than we gaze at a standard apartment block, and when we scrutinize paintings, our gaze slides along differently than when we look at a datasheet with numerals to be memorized. And how are training materials - manuals, video films and websites - perceived, when as much information should be gained from a glance? How should they be made up to work most effectively? Specialists of the Institute of Cognitive Neurology (Modern University for the Humanities) have been researching these questions.
Recording eye movements, the researchers found the way to impartially assess informational significance of video materials. To this end, they applied the method of video oculography. The main advantage of the method is that it is noninvasive, i.e., does not require any intervention in the organism – neither application of electrodes or putting on contact lenses.
The image of an eye where a dark pupil is distinctly distiguished is recorded by an ordinary video camera. Displacement of the pupil’s center along the eye image corresponds to displacement of a gaze along a visual stage. The system determines the pupil’s coordinates with accuracy of about 0.5 degrees of arc and with high frequency, and represents the eye movement along the image on the computer monitor in the form of a track.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
