Forget joysticks, use your torso to pilot drones

Virtual Reality - Science Daily - 16 July 2018 - 12:15pm
Your torso is more intuitive -- and more precise -- than joysticks for piloting drones, both simulated and real, according to a recent study. Work is already underway to implement this new body-machine-interface technology for search and rescue with drones.

AI-based framework creates realistic textures in the virtual world

Virtual Reality - Science Daily - 16 July 2018 - 8:45am
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.

Turn exercise into a game and see encouraging results

Virtual Reality - Science Daily - 12 July 2018 - 9:39am
A team of researchers built a web-based app called MapTrek. When synced with a Fitbit, MapTrek allows users to go on virtual walking tours of locations such as the Grand Canyon or Appalachian trail while competing against other users. A study showed MapTrek and Fitbit users averaged 2,200 more steps per day than a control group that used only Fitbits.

Seeing yourself as Einstein may change the way you think

Virtual Reality - Science Daily - 9 July 2018 - 7:12am
People experiencing Albert Einstein's body as their own through a virtual reality simulation were less likely to unconsciously stereotype older people, while those with low self-esteem scored better on a cognitive test. The results suggest that the experience allowed people with low self-esteem to change how they saw themselves and increase their cognitive potential. The technique could be useful for education, particularly for those with low self-esteem.

Virtual reality headsets significantly reduce children's fear of needles

Virtual Reality - Science Daily - 18 June 2018 - 7:26am
Almost anyone can relate to being afraid of needles and injections. A pilot study is the first to use a 3D virtual reality headset to test this tool as a distraction method in a pediatric setting. Children were given the choice of a roller coaster ride, helicopter ride or a hot-air balloon ride. Results show that anticipated versus actual pain and fear were reduced in 94.1 percent of the pediatric study subjects.

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.

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.
