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. ... >>

Advanced driver voice assistant 22.07.2014

The Israeli research center GM is developing a system for voice control of automotive functions. The project is being developed jointly with the British developer of speech recognition technologies VocalIQ.

General Motors (GM) is partnering with British technology firm VocalIQ to develop an advanced voice control system for vehicle functions. With the help of new items, drivers will be able not only to give short speech commands to automotive electronics, but also to conduct a dialogue with it.

Work on the project is being carried out at the GM Advanced Technical Center in Israel, which is developing technologies for unmanned vehicles, robots and human-machine interfaces. The cooperation between GM and VocalIQ has been going on for several months, but the conditions for further work have not yet been determined, The Wall Street Journal writes, citing informed informants.

According to the publication, GM and VocalIQ are working on a prototype dialogue management system, which is subsequently planned to be built into the infotainment systems of American brand cars. The presence of such a development in the car will allow its owner, without being distracted from the road, to control some salon functions by voice - for example, turn on the wipers, adjust the volume of the radio or set the route in the navigator.

Many GM models support the Apple Siri Eyes Free platform, which allows you to connect your iPhone to the on-board system and use the capabilities of a smartphone (read SMS messages aloud, dial a subscriber number, use a search engine, etc.) using voice communication. VocalIQ technology is more advanced than current speech recognition systems, explained Richard Anton of Amadeus Capital Partners (one of VocalIQ's main investors).

As Anton noted, the product of the British company is aimed at teaching cars to understand people, especially those things that have not been previously said. The world's first self-learning system is being developed that learns the words spoken by the driver and their meaning, making fewer errors over time, added VocalIQ co-founder Steve Young (Steve Young).
