No-Touch Tech

While much of exactly how the novel coronavirus is spread remains a mystery, we do know that it can last on some surfaces for days. Now, designers are working on what they’re calling “no-touch technology” in an effort to make things like elevators and checkout screens safe.

Prototypes are being developed that would allow us to press an elevator button, for example, by hovering a finger in the air and using sensors rather than making contact. And imagine just holding up two fingers to input a “2” into a touchscreen. This could be achieved through the use of ultraviolet light and sensors.

In some cases, voice technology can also replace touchscreens. As one of the engineers puts it, “Avoiding the need for touch is likely a better solution than relying on cleaning.”
