A touchscreen you don't need to touch

                Microsoft has unveiled an experimental touchscreen which you don’t even have to touch to use. The innovative display uses an array of sensors on the front and sides of the phone to detect the user’s finger when it’s hovering above the screen. This opens up a range of interesting new functionalities – for example, when playing video, the controls to pause, play and fast-forward only appear when the user goes to touch the screen, and disappear when the phone detects the finger has moced away. Browsing webpages becomes a lot smoother, as well – hyperlinks, which can make a page look busy and confusing, aren’t visible when a user is just reading an article. When they move to tap the screen, however, the links become visible, with more appearing as the user’s finger moves around the display.
