Virtual laboratory: Fast, flexible and exact

Virtual Reality - Science Daily - 18 July 2017 - 5:52am
During the forming process, sheet metal materials are often stressed to their limits. Computer simulations are used to test how far it is possible to go in production. However, the simulation is only ever as exact as the data on which it is based. Scientists have now developed a virtual test laboratory that allows them to examine different load states for metal materials and determine precise mechanical data.

Self-driving cars may soon be able to make moral and ethical decisions as humans do

Virtual Reality - Science Daily - 5 July 2017 - 9:32am
A ground-breaking new study challenges the assumption that moral decisions are strongly context dependent and cannot be modeled or described algorithmically, finding that human behavior in dilemma situations can be modeled by a simple value-of-life-based model. The research suggests that human moral behavior can be well-described by algorithms and used by machines to manage moral dilemmas on the road.

Tracking humans in 3D with off-the-shelf webcams

Virtual Reality - Science Daily - 5 July 2017 - 8:33am
Whether it's for computer games, motion analysis in sports, or even medical examinations, many applications require that people and their movements are captured digitally in 3D in real-time. Until now, this was possible only with expensive systems of several cameras, or by having people wear special suits. Computer scientists have now developed a system that requires only a single video camera. It can even estimate the 3D pose of a person acting in a pre-recorded video, for instance a YouTube video.

Improving virtual reality and exploring ear shape effects on 3-D sound

Virtual Reality - Science Daily - 26 June 2017 - 6:36am
Paris' Cathedral of Notre Dame has a ghost orchestra that is always performing, thanks to a sophisticated, multidisciplinary acoustics research. In the project, computer models use recordings from a live concert held at the cathedral and detailed room acoustic simulations to produce a novel type of audience experience: a virtual recreation of the live performance using spatial audio and virtual reality.

A unique data center for cosmological simulations

Virtual Reality - Science Daily - 20 June 2017 - 8:41am
Scientists have established 'Cosmowebportal', a unique data center for cosmological simulations. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

Visiting virtual beach improves patient experiences during dental procedures

Virtual Reality - Science Daily - 14 June 2017 - 6:18am
Imagine walking along a beach on a lovely day. As you turn to continue along the coast path feeling calm and relaxed you suddenly hear your dentist say 'Fine, all done, you can take the headset off now'. For patients at one dental practice in Devon, England, such Virtual Reality encounters are resulting in demonstrably better experiences in the dentist's chair.
