Researchers at Cambridge University have a touchless touch screen that uses AI to track user’s movements. The technology can have a wide range of applications as many devices, from cars to phones, feature a touch screen. The motivation for creating such a device stems from the current pandemic and the fear of transmitting germs via surfaces. COVID-19 has forced people to find new ways of carrying out tasks, and bright minds such as the ones at Cambridge University are leading us into a safer tomorrow.
