The base of the Horizon connects to a spring-supported hinge, which allows users to tilt the PC flat. When horizontal, the computer switches to Lenovo's Aura touch interface, which can capture 10 points of contact at once. Through Aura, users can browse photos and video or play games. The Horizon comes with four joysticks and four game pieces, each with a conductive pad that interacts with the touchscreen. The system even includes an accelerometer-equipped die that communicates with the board over the 2.4 GHz frequency. Lenovo and videogame studios, including EA and Ubisoft, are already using the Aura developer kit to code touch versions of new and classic games, such as Monopoly and air hockey. Players will be able to download more as they're published, eventually allowing the Horizon to replace both a computer and a closetful of games.
