Hololens puts holograms right into a physical environment, giving the user a new way to see the world. HoloLens is immersive, but it doesn’t block out the real world. It embeds holographic content and applications into physical surroundings to see, place and interact as if the holograms are part of the physical world. This mixed reality is enabling new ways to create, communicate, work and play.
The HoloLens features an inertial measurement unit (IMU) (accelerometer, gyroscope, and a magnetometer), four "environment understanding" sensors (two on each side), an energy-efficient depth camera with a 120°×120° angle of view, a 2.4-megapixel photographic video camera, a four-microphone array, and an ambient light sensor.
The front of the Hololens has many of the sensors and related hardware, including the processors, cameras and projection lenses. The visor is tinted, enclosed in the visor piece is a pair of transparent combiner lenses, in which the projected images are displayed in the lower half.
Along the bottom edges of the side, located near the user's ears, are a pair of small, red 3D audio speakers. The speakers, competing against typical sound systems, do not obstruct external sounds, allowing the user to hear virtual sounds, along with the environment. Using head-related transfer functions, the HoloLens generates binaural audio, which can simulate spatial effects; meaning the user, virtually, can perceive and locate a sound, as though it is coming from a virtual pinpoint or location.
