People remain calm as the world ends, video game study suggests

Virtual Reality - Science Daily - 20 March 2017 - 1:23pm
As the world ends, will you lock arms and sing 'Kumbayah' or embark on a path of law-breaking, anti-social behavior? A new study, based upon the virtual actions of more than 80,000 players of the role-playing video game ArcheAge, suggests you'll be singing. The study found that despite some violent acts, most players tended toward behavior that was helpful to others as their virtual world came to an end.

Computing: Is fog more secure than cloud?

Virtual Reality - Science Daily - 16 March 2017 - 8:26am
Computer scientists are working on a new concept for remote and distributed storage of documents that could have all the benefits of cloud computing but without the security issues of putting one's sensitive documents on a single remote server.

Female cyberbullies and victims feel the most negative about school and learning

Virtual Reality - Science Daily - 15 March 2017 - 6:44am
Involvement in cyberbullying among girls triggers negative perceptions of the importance of school and the value of learning, a new study suggests. Psychologists found that 11-15 year-old girls who were most involved in cyberbullying -- as perpetrator, victim, or both -- felt the least accepted by their peers. This then had a knock-on effect of spilling over into how important they felt school and learning were, the researchers found.

Studying altruism through virtual reality

Virtual Reality - Science Daily - 8 March 2017 - 10:13am
A computer-based environment has been developed with the aim to shed light on the origins of altruism. This new study immersed participants in a virtual environment that reproduced a building on fire which they had to evacuate in a hurry, deciding whether to save their lives or interrupt their escape and help rescue an injured person. The results showed that altruistic individuals self-reported to have greater concern for others’ wellbeing and had larger right anterior insula (a brain area involved in processing social emotions) compared to non-altruists.

Computer simulations first step toward designing more efficient amine chemical scrubbers

Virtual Reality - Science Daily - 7 March 2017 - 8:29am
A proof-of-concept molecular modeling study that analyzes the efficiency of amine solutions in capturing carbon dioxide is the first step toward the design of cheaper, more efficient amine chemicals for capturing carbon dioxide -- and reducing harmful CO2 emissions -- in industrial installations.

Virtual characters that touch you are seen as being warmer and friendlier

Virtual Reality - Science Daily - 6 March 2017 - 6:17am
Touch is a basic need. A new study has shown that virtual characters that can touch you are seen as being warmer and friendlier. Previous research had already shown that this applies to human interaction. This new study has demonstrated that the same principle applies to interactions with virtual characters.

Social exclusion in virtual realities has a negative social and emotional impact in 'real' life

Virtual Reality - Science Daily - 16 February 2017 - 7:55am
In this age of highly realistic computer games and increasingly popular social networks, social exclusion in virtual worlds is becoming more and more socially significant, as is demonstrated by the growing number of "cyber mobbing" cases. However, up until now, very little research has been carried out into the impact of social exclusion in the digital world upon real-life social behavior, and hardly any that addresses the latest developments such as Virtual Reality (VR) glasses. A study has now shown that exclusion from a virtual group has a significant negative impact upon willingness to help and social distance in the real world.

Complex 3D data on all devices

Virtual Reality - Science Daily - 6 February 2017 - 5:41am
A new web-based software platform is swiftly bringing the visualization of 3D data to every device, optimizing the use of, for example, virtual reality and augmented reality in industry. In this way, researchers have brought the ideal of “any data on any device” a good deal closer.

Heidelberg Castle revisited

Virtual Reality - Science Daily - 1 February 2017 - 6:36am
Strikes of lightning, fires, wars – not only ravages of time left their traces on Heidelberg Castle. Today, it is considered one of the most important renaissance buildings north of the Alps. And it is one of the most popular tourist destinations in Germany with about 1.1 million visitors from all over the world every year – many of them from English speaking countries and Asia. Now, a researcher has reconstructed the castle as it looked before its destruction by means of a three-dimensional virtual model.

Why scientists should research emojis and emoticons :-P

Virtual Reality - Science Daily - 17 January 2017 - 11:01am
More than 90 percent of online populations now incorporate emojis and emoticons into their texts and emails, and researchers are wondering what the use of (~_^), (>_<), or =D can reveal about human behavior. Emojis and emoticons can be used as tools for evaluating how we relate to each other in the digital age.

Realistic training for extreme flight conditions

Virtual Reality - Science Daily - 27 December 2016 - 5:33am
Missions at sea, in mountainous regions or close to skyscrapers are extremely risky for helicopter pilots. The turbulent air flows near oil rigs, ships, cliffs and tall buildings can throw a helicopter off balance and cause a crash. To provide pilots with optimal preparation for these challenging conditions, engineers are developing new simulation software.

Computer models find ancient solutions to modern climate problems

Virtual Reality - Science Daily - 20 December 2016 - 2:55pm
Archaeologists are at the helm of new research using sophisticated computer technology to learn how past societies responded to climate change. Their work, which links ancient climate and archaeological data, could help modern communities identify new crops and other adaptive strategies when threatened by drought, extreme weather and other environmental challenges.
