[[Microsoft HoloLens]] is an [[augmented reality headset]] developed by [[Microsoft]]. It is part of the [[Windows Mixed Reality]] [[AR Platform]] incorporated with [[Windows 10]] OS. HoloLens is an optical see-through head-mounted display. It may be similar to other [[OHMD]]s (optical head-mounted displays). Unlike the [[Oculus Rift]] and other [[Virtual Reality#Devices|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 (HD) virtual content over real world objects. <ref name=”one”>Microsoft. Microsoft HoloLens.

__TOC__
==General Information==
Microsoft HoloLens runs a self-contained Windows 10 computer.  It features an HD 3D optical head-mounted display, spatial sound projection and advanced sensors to allow its users to interact with AR applications through head movements, [[#Gesture|gestures]] and [[#Voice|voices]].


HoloLens has various sensors and a high-end CPU and GPU, which Microsoft says gives the headset more processing power than an average laptop. <ref name=”four”></ref>
The '''Microsoft HoloLens''' (commonly '''HoloLens 1''' or '''HoloLens Development Edition''') is the first [[mixed reality]] [[head-mounted display]] developed by [[Microsoft]], announced on January 21, 2015 and released on March 30, 2016 at $3,000 for the Development Edition. The HoloLens was the first self-contained, holographic computer with no wires, phones, or connection to a PC required, featuring Microsoft's revolutionary Holographic Processing Unit (HPU) capable of over one trillion operations per second. With see-through holographic lenses, gesture recognition, and spatial mapping, the original HoloLens pioneered the mixed reality category and established the foundation for enterprise AR applications.


The potential uses of the HoloLens are vast. From social apps to games, to navigation, there’s an incredible potential that this [[mixed reality]] device can tap into. Indeed, Microsoft collaborated with NASA in the making of HoloLens, and there is the potential to control the Mars rover Curiosity via the headset, allowing Nasa staff to work as if they were on the planet themselves. Microsoft also partnered with Volvo to showcase another possible use - using it in car showrooms for customers to view different color configurations for their chosen car and see features in action. <ref name=”four”></ref>
== History and Development ==


At the end of March 2016, holoportation was showcased. The video demonstration showed how it could be possible - through the use of multiple cameras - to use the HoloLens to view a 3D version of a person. <ref name=”four”></ref>
Microsoft unveiled the HoloLens on January 21, 2015 at a Windows 10 event, surprising the tech industry with a fully self-contained mixed reality headset. The Development Edition shipped on March 30, 2016 to developers in the United States and Canada for $3,000. A Commercial Suite was later offered for $5,000, providing enterprise features. The original HoloLens was succeeded by the significantly improved [[Microsoft HoloLens 2]] in 2019.<ref name="wikipedia">{{cite web |url=https://en.wikipedia.org/wiki/Microsoft_HoloLens |title=Microsoft HoloLens |publisher=Wikipedia |access-date=2025-01-07}}</ref>


While the HoloLens price is high, it is an impressive piece of hardware and indicates that Microsoft is taking the augmented reality and virtual reality markets seriously. <ref name=”three”></ref>

==Announcement and Release==
=== Display ===
Microsoft HoloLens was announced during a Windows 10 Event on January 21st, 2015. The Development Edition was released on March 30, 2016, for $3,000 or £2,000. It allowed developers to start making apps and games for the headset. Months later, it became available to anyone with a Microsoft account. During the last quarter of 2016, the program expanded beyond the United States into countries like the United Kingdom, Ireland, France, Germany, Australia and New Zealand. Currently, there’s still no information regarding a consumer edition release date. <ref name=”three”>Sophie, C. (2017). Microsoft HoloLens: Everything you need to know about the $3,000 AR headset.

==Features==
See-through holographic system:
Realistic 3D objects that can be anchored onto real life locations. These virtual objects are projected at about 60 cm (near plane) to few meters.


[[Spatial Mapping]] - scans the environment in real time to create a mesh of an X/Y/Z coordinate plane. Objects can be accurately projected into the mesh.
* Transparent holographic lenses
* '''1280x720 resolution per eye''' (HD)
* Over 2.5k light points per radian
* 60 Hz refresh rate
* Waveguide-based optics
* Additive display (holograms on real world)


[[Spatial Audio]] - in-app audio will come from different directions which depend on where you are in relation to the virtual object making the sound
=== Field of View ===


[[#Voice|Voice Recognition]] - recognizes various voice commands.
* '''~35° diagonal FOV'''
* 30° horizontal
* 17.5° vertical
* Primary criticism of original HoloLens
* Limited hologram viewing area


[[#Gesture|Gesture Recognition]] - recognizes various gesture commands such as the [[Air Tap]].
=== Processing ===


[[#Gaze|Gaze Recognition]] - HoloLens tracks your gaze.
Custom computing architecture:


==Hardware==
==== Intel Atom Processor ====
===Review===
* Intel Atom x5-Z8100 (Cherry Trail)
'''Headset and Display'''
* 1.04 GHz frequency
* 64-bit quad-core


HoloLens requires neither cords nor phones. It features an optical [[HMD]] on top of a plastic ring that wraps around the head. The plastic ring has a soft foam cushion on the inside. Like other HMDs, the weight of HoloLens is front loaded and feels a bit bulky. HoloLens can be used with most prescription glasses.
==== Holographic Processing Unit (HPU) ====
* '''Microsoft HPU 1.0'''—revolutionary custom chip
* '''24 cores'''
* '''>1 trillion operations per second'''
* 200x faster than software processing
* Processes "terabytes of information"
* Dedicated to spatial computing


The transparent dual displays are made of three layers of glass (red, blue and green). A light engine is mounted above the displays and projects light on the lenses. The tiny corrugated grooves in each layer of glass diffract these light particles, making them bounce around and helping to trick your eyes into perceiving virtual objects at virtual distances.
==== Memory ====
* '''2 GB RAM'''
* '''64 GB storage'''


The [[field of view]] where the virtual objects appear is quite small - 30° horizontal and 17.5° vertical. It is the same as a 16:9 monitor with 15 feet diagonal, 2 feet away from you face.
=== Sensors ===


'''Sensors'''
Comprehensive spatial awareness:


Sensors include head tracking [[IMU]]s (Inertial Measuring Unit); a sound capture system consisting of an array of 4 microphones; an energy efficient depth camera with 120°×120° [[FOV]], an RGB 2-megapixel photo / HD video camera and an ambient light sensor. Additionally, it has 4 greyscale environment sensing cameras that work with the depth camera to track the head, hands and the surrounding environment.
* 1 depth camera
* 4 environment understanding cameras
* 1 HD video camera (2.4 MP)
* Mixed reality capture
* Ambient light sensor
* 4 microphones
* IMU (accelerometer, gyroscope, magnetometer)


'''Processors'''
=== Tracking ===


For processors, in addition to [[CPU]] and [[GPU]], HoloLens possess an [[HPU]], ([[holographic processing unit]]). The HPU is a coprocessor 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.
Self-contained inside-out tracking:


[[HPU]] - processes all of the data from its sensors, depth camera, microphone etc.
* '''6 Degrees of Freedom''' (6DoF)
* No external sensors required
* Spatial mapping of environment
* Real-time mesh generation
* Anchor placement


'''Audio'''
=== Input Methods ===


The [[3D audio|Spatial sound system]] consists of 2 small speakers are located on the sides of the OHMD, sitting above the ears. Unlike headphones, these speakers do not prevent the user from hearing external sounds. In-app audio will come from different directions which depend on where you are in relation to the virtual object making the sound.
Controller-free interaction:


'''Input and Interface'''
=== Gestures ===
* Air tap (select)
* Bloom (go to Start)
* Gaze targeting
* Hand gesture recognition


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.
