#4 Sony Xperia sola With 'Floating Touch'  

Sony produces a series of touch phones in the Xperia category and as a first step of moving towards the gesture control technique, it has introduced a new technology, “Floating Touch,” in its new Smartphone Xperia Sola. It is the first ever phone to use the technology which allows you to use your fingers like a mouse or cursor over the phone’s display to highlight icons and links without even touching them. Just move your finger in the air near the display to maneuver through the choices and select them. It can be the touchless-Smartphone- control technology in future Smartphones.
