When fish swim in the holodeck

Virtual Reality - Science Daily - 21 August 2017 - 8:36am
Standard behavior experiments to investigate behavior in popular lab animals only incompletely mimic natural conditions. The understanding of behavior and brain function is thus limited. Virtual Reality helps in generating a more natural experimental environment but requires immobilization of the animal, disrupting sensorimotor experience and causing altered neuronal and behavioral responses. Researchers have now developed a VR system for freely moving animals to overcome most of these limitations.

Telemedicine as effective as in-person care for Parkinson's disease

Virtual Reality - Science Daily - 16 August 2017 - 1:06pm
Telemedicine can successfully deliver quality care, new findings from a nationwide program that links neurologists with patients with Parkinson's disease in their homes via video conferencing shows. The study points to a new way to improve care for people who suffer from the disease, but may have not have access to a neurologist.

The importance of influencers on social media

Virtual Reality - Science Daily - 10 August 2017 - 7:48am
Tracking the Twitter updates of a random sample of 300,000 active users over the course of a month reveals that this particular corner of social media and social networking is not quite as equitable and democratic as popular perception might have us believe. Indeed, the research reveals that there is a two-step flow of information through which a minority of users accounts for the majority of influence.

Somersaulting simulation for jumping bots

Virtual Reality - Science Daily - 26 July 2017 - 3:43pm
Engineers have been developing new technologies to enable robots and humans to move faster and jump higher. Soft, elastic materials store energy in these devices, which, if released carefully, enable elegant dynamic motions. A pair of new computational methods takes first steps towards automating the design of the dynamic mechanisms behind these movements.

'Magic Bench' lets users see, hear and feel animated characters

Virtual Reality - Science Daily - 26 July 2017 - 7:29am
Sit on Disney Research's Magic Bench and you may have an elephant hand you a glowing orb. Or you might get rained on. Or a tiny donkey might saunter by and kick the bench. It's a combined augmented and mixed reality experience, but not the type that involves wearing a head-mounted display or using a handheld device. Instead, the surroundings are instrumented rather than the individual, allowing people to share the 'magical' experience as a group.

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.
