Changes

Sensors include head tracking [[IMU]]s, sound capture system consist of an array of 4 microphones, an energy efficient depth camera with 120°×120° [[FOV]], an a RGB 2-megapixel photo and / HD video camera and an ambient light sensor. Additionally, it has 4 greyscale environment sensing cameras that work with the depth camera to track your head, hands and the surrounding environment.

For processors, in addition to [[CPU]] and [[GPU]], HoloLens will possess an [[HPU]], [[holographic processing unit]]. HPU is a coprocessor that is dedicated to integrating real world and virtually generated content. It consolidates and processes all the data from various sensors and produces a thin stream of useful information to the other processors. HPU removes the burden of handling heavy external data from the CPU and GPU, allowing them to focus on creating content.
