Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Robomobiles will be able to make decisions based on morality 15.07.2017

The development of autonomous driving technologies has raised many questions, including the difficult problem for autonomous systems of potential life-or-death decision making. Should autonomous car systems protect the lives of their owners at all costs, or will they have to sacrifice a driver to save a large group of people from death?

While there is no concrete answer to this question, a research team from Germany believes that morality may soon play a role in how self-driving cars will make decisions.

Evidence suggests that human morality is too context-dependent to accurately model, meaning that it cannot be effectively integrated into a self-governing algorithm.

Study participants were asked to drive a car in virtual reality through city streets on a foggy night. In virtual travels, they created emergency situations when it was impossible to avoid a collision with inanimate objects, animals or people. The subsequent decisions were modeled and turned into a set of rules creating a "value of life" model for every person, animal and inanimate object that might be involved in a traffic incident.

“Now that we know how to implement human ethical decisions into machines, we as a society are still left with a double dilemma,” says Professor Peter Koenig. “First, we must decide whether moral values should be included in the guidelines principles of how machines behave, and secondly, if there are any, should machines act in exactly the same way as people?
