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."

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
