The Light Touch can turn that image into a touch-screen that you can type on or swipe through with the help of a holographic laser projection and infrared sensor at the bottom of the device.
Thanks to the IR sensor, the phone's browser responds to an "up swipe" in the air above it with by scrolling up, and to a "side" swipe by jumping to another tab.
Rather than using a passcode or swipe pattern to unlock the phone's screen, the new handset's fingerprint sensor allows users to simply press and slide a finger across a switch to quickly unlock it.
