'Touchless touchscreen' could fight future epidemics, researchers say

Cambridge University researchers have developed a "no-touch touchscreen" that uses artificial intelligence to predict a user's intention before their hand reaches the display. The screen was originally designed for use in cars, but the engineers who built it claim it could also have widespread applications during a pandemic. The "predictive touch" technology can be retrofitted to existing displays and could be used to prevent the spread of pathogens on touchscreens at supermarket check-outs, ATMs and ticket terminals at railway stations. Studies have shown that coronavirus can remain on plastic and glass for anywhere between two hours and a week, meaning touchscreens in public places need to be constantly disinfected to prevent transmission. "Touchscreens and other interactive displays are something most people use multiple times per day, but they can be difficult to use while in motion, whether that's driving a car or hanging the music on your phone while you're running," said Simon Godsill from the university's department of engineering.
