Introduction of HoloLensMicrosoft HoloLens is a Augmented Reality device developed by Microsoft.

It is part of the Windows Holographic AR Platform incorporated with Windows 10 OS

Similar to other OHMDs, HoloLens is a see through display worn over your eyes.

Unlike Oculus Rift and VR Devices, the eye-piece component of HoloLens is transparent and the headset requires neither PC nor smartphone.

It is able to project high-definition virtual content or holograms over real world objects.

It features HD 3D optical head-mounted display, spatial sound projection and advanced sensors to allow its users to interact its AR applications through head movements, gestures and voices.

Display and Sound• The smart glass head-mounted display requires neither cords nor phones. It

features a HD 3D optical head-mounted display, spatial sound system along with various sensors.

• The eye-piece consist of a tinted visor with a pair of combiner lenses within. 2 small speakers are located on the sides of OHMD. 

• Unlike headphones, these speakers do not prevent the user from hearing external sound.

• The field of view where the holograms appear is quite small, estimated to be around 40°.

Sensors and Processors• Sensors include head tracking IMUs, sound capture system consist of various

microphones, an energy efficient depth camera with 120°×120° FOV and a RGB video camera.

• HPU - processes all of the data from its sensors, depth camera, microphone etc.• 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.

Input and Interface• A pair of buttons responsible for brightness is above the left ear while another pair

of buttons responsible for volume is above the right ear. • In each pair, one of the buttons is concave while the other one is convex.• 5 LEDs are present on the left side of the OHMD. • These LEDs display various system statuses such as power and battery conditions.

A microUSB port is present for charging and connection.

FEATURES

Spatial Audio

Voice Recognition

Gesture Recognition

Gaze Recognition

Air Tap

Spatial Mapping

FEATURES• Anchor holograms onto real life objects. Virtual objects are projected at about 60

cm (near plane) to few meters.• Spatial Mapping - Scans the environment in the real time to create a mesh of an

X/Y/Z coordinate plane. Objects can be accurately projected into mesh.• Spatial Audio - Spatial Audio is sound that has been processed to give the listener

a sense of the location of a virtual sound source and the characteristics of a virtual listening space.

• Voice Recognition - Computer analysis of the human voice, especially for the purposes of interpreting words and phrases or identifying an individual voice.

• Gesture Recognition - Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms.

• Gaze Recognition (or) Eye Tracking – It is the process of measuring either the positions and eye movement.
