Microsoft HoloLens, known under development as Project Baraboo, are a pair of mixed reality smartglasses developed and manufactured by Microsoft. HoloLens was the first head-mounted display running the Windows Mixed Reality platform under the Windows 10 computer operating system. The tracking technology used in HoloLens can trace its lineage to Kinect, an add-on for Microsoft's Xbox game console that was introduced in 2010.
The pre-production version of HoloLens, the Development Edition, shipped on March 30, 2016, and is targeted to developers in the United States and Canada for a list price of $3000. Samsung and Asus have extended an offer to Microsoft to help produce their mixed-reality products, in collaboration with Microsoft, based around the concept and hardware on HoloLens. On October 12, 2016, Microsoft announced the global expansion of HoloLens and publicized that HoloLens would be available for preorder in Australia, Ireland, France, Germany, New Zealand and the United Kingdom There is also a Commercial Suite (similar to a pro edition of Windows), with enterprise features, such as BitLocker security. As of May 2017, The Suite sold for US$5,000. Microsoft has decided to rent the Hololens without clients making the full investment. Microsoft partners with a company called Abcomrents to give the service of Hololens rental.
HoloLens 2 was announced at the Mobile World Congress (MWC) in Barcelona, Spain, on February 24, 2019, and was available on preorder at US$3,500.
Description:
The HoloLens is a head-mounted display unit connected to an adjustable, cushioned inner headband, which can tilt HoloLens up and down, as well as forward and backwards. To wear the unit, the user fits the HoloLens on their head, using an adjustment wheel at the back of the headband to secure it around the crown, supporting and distributing the weight of the unit equally for comfort, before tilting the visor towards the front of the eyes.
The front of the unit houses 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. The HoloLens must be calibrated to the interpupillary distance (IPD), or accustomed vision of the user.
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. On the top edge are two pairs of buttons: display brightness buttons above the left ear, and volume buttons above the right adjacent buttons are shaped differently—one concave, one convex—so that the user can distinguish them by touch.
At the end of the left arm is a power button and row of five, small individual LED nodes, used to indicate system status, as well as for power management, indicating battery level and setting power/standby mode. A USB 2.0 micro-B receptacle is located along the bottom edge. A 3.5 mm audio jack is located along the bottom edge of the right arm.
Hardware:
The HoloLens features an inertial measurement unit (IMU) (which includes an 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.
In addition to an Intel Cherry Trail SoC containing the CPU and GPU, HoloLens features a custom-made Microsoft Holographic Processing Unit (HPU), a coprocessor manufactured specifically for the HoloLens by Microsoft. The SoC and the HPU each have 1GB LPDDR3 and share 8MB SRAM, with the SoC also controlling 64GB eMMC and running the Windows 10 operating system. The HPU uses 28 custom DSPs from Tensilica to process and integrate data from the sensors, as well as handle tasks such as spatial mapping, gesture recognition, and voice and speech recognition. According to Alex Kipman, the HPU processes "terabytes of information," one attendee estimated that the display field of view of the demonstration units was 30°×17.5°.In an interview at the 2015 Electronic Entertainment Expo in June, Microsoft Vice-President of Next-Gen Experiences, Kudo Tsunoda, indicated that the field of view is unlikely to be significantly different on the release of the current version. The HoloLens contains an internal rechargeable battery, with average life rated at 2–3 hours of active use, or 2 weeks of standby time. The HoloLens can be operated while charging.
HoloLens features IEEE 802.11ac Wi-Fi and Bluetooth 4.1 Low Energy (LE) wireless connectivity. The headset uses Bluetooth LE to pair with the included Clicker, a thumb-sized finger-operating input device that can be used for interface scrolling and selecting. The Clicker features a clickable surface for selecting and an orientation sensor that provides for scrolling functions via tilting and panning of the unit. The Clicker features an elastic finger loop for holding the device and a USB 2.0 micro-B receptacle for charging its internal battery.

Interface.
HoloLens, through the use of the HPU, uses sensual and natural interface commands—gaze, gesture, and voice—sometimes referred to as "GGV", inputs.[61] Gaze commands, such as head-tracking, allow the user to bring application focus to whatever the user is perceiving."Elements"—or any virtual application or button—are selected using an air tap method, similar to clicking an imaginary computer mouse. The tap can be held for a drag simulation to move an element, as well as voice commands for certain commands and actions.
The HoloLens shell carries over and adapts many elements from the Windows desktop environment. A "bloom" gesture for accessing the shell (performing a similar function to pressing a Windows key on a Windows keyboard or tablet, or the Xbox button on an Xbox One Controller) is performed by opening one's hand, fingers spread with the palm facing up. Windows can be dragged to a particular position, as well as resized. Virtual elements such as windows or menus can be "pinned" to locations, physical structures or objects within the environment; or can be "carried," or fixed with the user, following the user as they move around. Title bars for application windows have a title on the left, and buttons for window management functions on the right.
In April 2016 Microsoft Created the Microsoft HoloLens App for Windows 10 PC's and Windows 10 Mobile devices, which allows developers to run apps, use his or her phone or PC's keyboard to type text, view a live stream from the HoloLens user's point of view, and remotely capture mixed reality photos and videos.
Developing applications for HoloLens:
Microsoft Visual Studio is an IDE that can be used to develop applications (both 2D and 3D) for HoloLens. Applications can be tested using HoloLens emulator (included in Visual Studio 2015 IDE) or HoloLens Development Edition.
2D applications
HoloLens can run almost all Universal Windows Platform apps. These apps appear as 2D projections. Not all Windows 10 APIs are currently supported by HoloLens, but in most cases, the same app can run across all Windows 10 devices (including HoloLens), and the same tools that are used to develop applications for Windows PC or Windows Phone can be used to develop a HoloLens app.
3D applications
3D applications, or "holographic" applications, use Windows Holographic APIs. Microsoft recommends Unity engine and Vuforia to create 3D apps for HoloLens, but it's also possible for a developer to build their engine using DirectX and Windows APIs.
Critics:
In November 2018 Microsoft got a contract for the supply of 100,000 HoloLens MR glasses, worth US$479 million, to the U.S. military. The MR goggles are intended to provide "increased lethality, mobility, and situational awareness necessary to achieve overmatch against [...] current and future adversaries." Just before the opening of one of the largest international technology conferences - the GSMA Mobile World Congress 2019 in Barcelona - fifty Microsoft employees wrote a letter to their CEO Satya Nadella and President Brad Smith stating that they "refuse to develop technologies for warfare and oppression". They demanded that corporate management terminate the contract.
