Phoenix, AZ - November 8th, 2012 -- Sensor fusion has become an important feature for many portable devices, in particular smartphones, tablets and the emerging Ultraportable PCs. In fact, sensor fusion is required by Windows 8 for all tablet PCs and all convertible Ultrabooks, and recommended for clamshell Ultrabooks. Intel offers reference platforms for tablets and Ultrabooks that include a sensor hub block connected directly to the CPU. Many advanced applications are enabled by sensor fusion, including geo-fencing, gesture controls and context awareness.
