−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 using its see-through display.<ref name=”one”>Microsoft. Microsoft HoloLens.

+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]]. Microsoft has said that “The key to a great holographic experience is holograms that are light point rich, i.e. have a high holographic density, and are pinned or anchored to the world around you. To achieve this, HoloLens has been designed for optimal holographic density of 2.5K radiants. The more radiants and light points there are, the brighter and richer the holograms become.” <ref name=”four”>Roberts, J. (2016). What is HoloLens? Microsoft’s holographic headset explained.

−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>
−
−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>

−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==
−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.

−The '''HoloLens 1''' is an [[augmented reality headset]] with an optical see through head mounted display (OST-HMD), developed by [[Microsoft]].
−Microsoft markets the HoloLens as holographic, but it is not. Microsoft misunderstands what holograms are.

−==General Information==
+==Operation==
−[[File:Hololens augmented reality.jpeg|thumb|HoloLens in use]]
−HoloLens uses cameras to track the environment and establish a frame of reference.
−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>
−==Hardware==
+==Displays==
−The [[field of view]] where the holograms 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.
+The [[field of view]] (FOV) is small: 30 degrees horizontal and 17.5 degrees vertical.
−'''Sensors'''
+Its total diagonal FOV is about 30 degrees.<ref name="v477">{{cite web | title=How does the Hololens 2 matter? | website=Steve's Space | date=2019-02-24 | url=https://stevesspace.com/2019/02/how-does-hololens2-matter/ | access-date=2024-09-26}}</ref>
−It is optically comparable with the [[Hololens 2]] and the [[Magic Leap 1]].
−==3D tracking==
+Sensors include head tracking [[IMU]]s (Inertial Measuring Unit), a 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.
−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.

−HoloLens can connect to any WiFi or Bluetooth-equipped device.
−HoloLens can run any universal Windows 10 app.
−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. There is also a Power button. These are the only physical inputs - HoloLens is largely controlled by [[#Voice|voice]], [[#Gesture|gesture]] and [[#Gaze|gaze]] along with [[HoloLens Clicker|a bluetooth clicker]]

'''[[HoloLens Clicker]]''' - a small clicker with a loop that wraps around your middle or index finger. It is held with the microUSB port towards your body and your thumb resting on top of the click, in the indentation. The clicker features a single button and [[rotational tracking]]. It allows a user to click and scroll with minimal hand motion as a replacement for the air-tap gesture.
