I guess now we all know what a touchscreen is and how it works. We can interact with it by touching it with our fingertips, and we can also perform certain gestures to perform certain actions, such as pressing two fingers and making a gesture to open or close them or zoom out.
This is no secret, after all, on the touch screen what we do with our fingers is the same as on the traditional PC-mouse interface. This is because your fingers become the cursor and the device is removed. Without this type of interface, it would be impossible to reach the point of technological evolution where we are today, but touch screens also have their drawbacks.
Currently, one of the most important factors is the amount of dirt that accumulates and the risk of it becoming a source of bacteria and viruses. Let’s pause at this point for a moment, let’s think that you hardly ever have clean hands when using a smartphone. In fact, many users perform activities that are not recommended at all, such as washing their hands and touching the phone screen. If the screen is not clean and you start eating, there is an obvious risk.
I think the idea we want to convey is perfectly understood with the example we have set, and that is why experts recommend cleaning our smartphone screen more often than ever before.
A group of scientists from the University of Cambridge has set out to solve the problem of dirt and the build-up of viruses and bacteria on such screens by developing a touchscreen that does not need to be touched. I know you are wondering how this is possible, and rest assured we will find out.
Researchers defined the patent behind the technology as “predictable touch”, and its development was supported by auto giants such as Jaguar Land Rover. This technology allows the user to navigate between different touchscreen options and select them without having to touch them, thanks to a set of sensors that, assisted by the artificial intelligence system, are able to determine the option that the user wants to choose.
It’s a simpler concept than it sounds, but just as interesting and very useful, especially now that we’re still in the midst of the COVID-19 pandemic, a highly contagious disease that requires a high degree of hygiene. And disinfection to minimize the risk of contamination.
Experts have confirmed that this type of display can be easily used on smartphones and other mobile devices, and the technology on which it is based is so strong that it works without problems with people with nervous problems and tremors.
