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 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.

Leap Motion keyboard works without touch 13.06.2014

The Leap Motion keyboard, which can track human hand movements and thus control a computer without touching it, will be sold separately. The cost of the product will be $99.

Previously, the innovative peripheral could only be purchased bundled with some HP PCs. The developers never talked about plans to distribute this keyboard as a standalone product. According to Engadget, Leap Motion will appear in retail during June. The novelty will be compatible with all desktops and laptops running Windows 7 and Windows 8 operating systems.

Recall that Leap Motion technology allows you to interact with computers using spatial gestures, reminiscent of the principle of Kinect in Xbox game consoles. For this, built-in miniature sensors are used.

Leap Motion has its own app store called Airspace, where programs and games specifically designed for gesture control are available. The Airspace portal was launched in the summer of 2013, since then software sales there have exceeded 500 titles.

The HP Leap Motion Keyboard is included with HP ENVY Recline, ENVY Touchsmart, Pavilion 23 and more.
