Building on principles of binocular geometry established by Leonardo da Vinci, Drs. Kevin Brooks and Barbara Gillam of the University of New South Wales in Sydney, Australia, conducted a series of experiments in which observers were asked to match the amplitude of motion in depth seen through stereoscopic stimuli presented on two computer monitors. Dynamic versions of a monocular gap stereogram were used to produce a percept of motion in depth from changes in the locations of unmatched features, despite a lack of any previously known cues to 3D motion. The studies showed that while the established cues of changing disparity (CD) and interocular velocity difference (IOVD) are involved in the percept of motion in depth for features visible in both eyes, a new cue, dynamic half-occlusion, is used when unmatched features are observed.
"The benefits of this knowledge enhance the potential for creating more effective simulation of motion in 3D displays and virtual environments," said Brooks. "It will also be interesting to see whether neurophysiological studies are able to locate the cells that mediate these processes."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
