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. ... >>
| Random news from the Archive Computer vision for electric scooter
20.07.2022
Electric bike and scooter manufacturer and rental company Lime has announced plans to introduce Advanced Rider Assistance Systems.
For this, a proprietary computer vision platform was created to detect sidewalk driving. In such cases, the user will be notified of the violation by an audible signal or by forcibly reducing the speed of movement.
Lime will begin testing the new system on 400 scooters in San Francisco by mid-August. By the end of the year, it is planned to expand the pilot project to six cities, including Paris, where the company demonstrated the new technology for the first time.
It is noted that in recent times, many large micromobility services have tried to implement some form of ARAS for scooters. Bird, Superpedestrian, and Neuron rely on location-based systems to track where users drive and park. Voi, Spin and Zipp have tried third-party computer vision technologies.
The company has also been testing third-party computer vision systems to test the viability of this approach. Ultimately, the decision was made to invest in a proprietary technology that would detect and prevent sidewalk incidents.
ARAS systems based on location and computer vision have many supporters. Adherents of the first option note that the location system is cheaper and easier to integrate.
It is also noted that computer vision technology is not yet developed enough to be truly effective. Not to mention, computer vision requires additional hardware that can break or be vandalized on the streets.
