Display and camera in one

The Display That Watches You
“By interlacing photodetector cells–similar to those used to capture light in a camera–with display pixels, the researchers have built a system that can display a moving image while also detecting movement directly in front of it. Tracking a person’s eye movements while she looks at the screen could allow for eye-tracking control: instead of using hand controls or another form of input, a user could flip through menu options on a screen by looking at the right part of the screen. The researchers envisage eventually integrating the screen with an augmented-reality system.”
