Many designers for the virtual world find it challenging to design efficiently believable complex textures or patterns on a large scale. Indeed, so-called 'texture synthesis,' the design of accurate textures such as water ripples in a river, concrete walls, or patterns of leaves, remains a difficult task for artists. A plethora of non-stationary textures in the 'real world' could be re-created in gaming or virtual worlds, but the existing techniques are tedious and time-consuming.
Your torso is more intuitive -- and more precise -- than joysticks for piloting drones, both simulated and real, according to a recent study by EPFL scientists. Work is already underway to implement this new body-machine-interface technology for search and rescue with drones.
Army researchers have discovered that being initially uncertain when faced with making critical mission-related decisions based on various forms of information may lead to better overall results in the end.
A team of researchers led by Simon Fraser University professor Carman Neustaedter suggests that while there may be obvious benefits to implementing video calling for 911, there are also technical and social challenges to ensuring the system works optimally.
MIT's Cheetah 3 robot can now leap and gallop across rough terrain, climb a staircase littered with debris, and quickly recover its balance when suddenly yanked or shoved, all while essentially blind. The 90-pound mechanical beast -- about the size of a full-grown Labrador -- is intentionally designed to do all this without relying on cameras or any external environmental sensors.
Researchers from Chalmers University of Technology, Sweden, and Tallinn University of Technology, Estonia, have demonstrated a 4,000 kilometer fiber-optical transmission link using ultra low-noise, phase-sensitive optical amplifiers. This is a reach improvement of almost six times what is possible when using conventional optical amplifiers. The results are published in Nature Communications.
A research team, led by computer scientists from the University of Bern-Switzerland and University of Maryland-College Park, have devised a sketch-based editing framework that enables a user to edit their photos by sketching a few strokes on top of them.
Using graphene, one of science's most versatile materials, engineers from the UCLA Samueli School of Engineering have invented a new type of photodetector that can work with more types of light than its current state-of-the-art counterparts. The device also has superior sensing and imaging capabilities.
Smartphones and touchscreens could turn museum visits into a digital and multimedia experience. In the months ahead, an example of this can be seen in Admont Abbey in Austria. In a special exhibition, the abbey is presenting fragments of the 'Admonter Abrogans', a Latin-German dictionary from the period of around 800. The cultural treasures have been made accessible through a multi-media presentation, which researchers of the Institute of Creative\Media/Technologies at St. Pölten University of Applied Sciences (Austria) has designed.
Researchers at the University of York have shown that a new quantum-based procedure for distributing secure information along communication lines could be successful in preventing serious security breaches.
