Soft machines: Fast, low-voltage actuator for soft and wearable robotics

Virtual Reality - Science Daily - 21 May 2018 - 11:38am
In the world of robotics, soft robots are the new kids on the block. The unique capabilities of these automata are to bend, deform, stretch, twist or squeeze in all the ways that conventional rigid robots cannot. Today, it is easy to envision a world in which humans and robots collaborate -- in close proximity -- in many realms. Emerging soft robots may help to ensure that this can be done safely, and in a way that syncs to human environments or even interfaces with humans themselves.

Your body is transparentized in a virtual environment

Virtual Reality - Science Daily - 15 May 2018 - 5:17am
Researchers have found that visual-motor synchronicity of only the hands and feet can induce a sense of illusory ownership over an invisible body interpolated between virtual hands and feet. This active method to induce a sense of illusory ownership over an invisible body at a distance has potential applications in skill learning/transfer and the concept of body-appearance-irrelevant communication in the future.

Virtual avatar-to-avatar interviews may improve eyewitness testimony

Virtual Reality - Science Daily - 14 May 2018 - 9:25am
Virtual avatar-to-avatar eyewitness interviews may increase the quantity and quality of recalled information compared to face-to-face interviews. A first-of-its-kind study shows that eyewitnesses of a mock car theft provided as much as 60 percent more information when interviewed in an avatar-to-avatar context compared to face-to-face interviews. Study participants also found it easier to talk to the avatar and were more likely to admit when they didn't know the answer to a question.

Would video games be better if you could play as yourself? Well, not exactly

Virtual Reality - Science Daily - 10 May 2018 - 8:50am
A new study shows no gender difference or negative effect on a video game player's performance or subjective involvement based on whether a photorealistic avatar looked like them or like their friend.

Virtual reality technology opens new doors of (spatial) perception

Virtual Reality - Science Daily - 9 May 2018 - 5:20am
Locating and discriminating sound sources is extremely complex because the brain must process spatial information from many, sometimes conflicting, cues. Using virtual reality and other immersive technologies, researchers can use new methods to investigate how we make sense of the word with sound.

Could robots be counselors? Early research shows positive user experience

Virtual Reality - Science Daily - 3 May 2018 - 11:27am
New research has shown for the first time that a social robot can deliver a 'helpful' and 'enjoyable' motivational interview (MI) -- a counseling technique designed to support behavior change.

Should ethics or human intuition drive the moral judgments of driverless cars?

Virtual Reality - Science Daily - 3 May 2018 - 11:26am
Driverless cars will encounter situations requiring moral assessment -- and new research suggests that people may not be happy with the decisions their cars make. Experiments designed to test people's reactions to a driving dilemma that endangers human life, revealed a high willingness for self-sacrifice, a consideration of the age of potential victims and swerving onto the sidewalk to save more lives -- intuitions that are sometimes at odds with ethically acceptable behavior or political guidelines.

Move over Tupac! Life-size holograms set to revolutionize videoconferencing

Virtual Reality - Science Daily - 25 April 2018 - 9:02am
TeleHuman 2 -- the world's first truly holographic videoconferencing system -- is being unveiled. TeleHuman2 allows people in different locations to appear before one another in life-size 3-D -- as if they were in the same room.

Making computer animation more agile, acrobatic -- and realistic

Virtual Reality - Science Daily - 10 April 2018 - 1:11pm
Animation in film and video games is hard to make realistic: each action typically requires creating a separate controller, while deep reinforcement learning has yet to generate realistic human or animal motion. Computer scientists have now developed an algorithm that uses reinforcement learning to generate realistic simulations that can even recover realistically, after tripping, for example. The same algorithm works for 25 acrobatic and dance tricks, with one month of learning per skill.

A Zika vaccine could virtually eliminate prenatal infections, model shows

Virtual Reality - Science Daily - 2 April 2018 - 2:10pm
A Zika vaccine could have a substantial effect on mitigating and preventing future Zika virus outbreaks. Through a combination of direct protection and indirect reduction of transmissions, virtual elimination is achievable, even with imperfect vaccine efficacy and coverage, according to a new computer model.

Ag robot speeds data collection, analyses of crops as they grow

Virtual Reality - Science Daily - 12 March 2018 - 5:16pm
A new lightweight, low-cost agricultural robot could transform data collection and field scouting for agronomists, seed companies and farmers. The TerraSentia crop phenotyping robot measures the traits of individual plants using a variety of sensors, including cameras, transmitting the data in real time to the operator's phone or laptop computer.

Virtual predator is 'self-aware', behaves like living counterpart

Virtual Reality - Science Daily - 1 March 2018 - 7:31am
Scientists report that they've built an artificially intelligent ocean predator that behaves a lot like the original flesh-and-blood organism on which it was modeled. The virtual creature, 'Cyberslug,' reacts to food and responds to members of its own kind much like the actual animal, the sea slug Pleurobranchaea californica, does.

Worm 'uploaded' to computer and taught amazing tricks

Virtual Reality - Science Daily - 6 February 2018 - 7:58am
The tiny worm C. elegans is the only living being whose neural network has been analyzed completely. It can therefore be transferred to a computer, creating a virtual copy of the worm which behaves in exactly the same way to external stimuli. Such a 'virtual worm' can learn amazing tricks -- its neural network can even be used to balance a pole, which is a standard control problem in computer science.
