Microsoft HoloLens 2 is a pair of mixed reality smartglasses developed and manufactured by Microsoft. It is the successor to the pioneering Microsoft HoloLens. On February 24, 2019 the HoloLens 2 enterprise edition debuted as the first variant of the device, followed by a developer edition that was announced on May 2, 2019. It was subsequently released in limited numbers on November 7, 2019.

Description[]

The HoloLens 2 was announced by lead HoloLens developer Alex Kipman on February 24, 2019 at Mobile World Congress (MWC) in Barcelona, Spain.[2][3] On May 7, 2019 the HoloLens 2 was shown again at the Microsoft Build developer conference. There, it showcased an application created with the Unreal Game Engine.[4]

The HoloLens 2 are combination waveguide and laser-based stereoscopic & full-color mixed reality smartglasses developed and manufactured jointly by Microsoft and MicroVision, Inc.[5] in Redmond, Washington. It is the direct model successor to the pioneering Microsoft HoloLens and the technical successor to the MicroVision stereoscopic and monochromatic laser-based virtual retinal display (VRD) & helmet mounted display (HMD) prototype-in-the-running for the canceled RAH-66 Comanche stealth helicopter [6] and the now-defunct monoscopic and monochromatic MicroVision .[7] On February 24, 2019 the HoloLens 2 enterprise edition debuted as the first variant of the device, followed by a developer edition that was announced on May 2, 2019. It was subsequently released in limited numbers on November 7, 2019. The US military's Integrated Visual Augmentation System is a further development of Hololens 2.

On August 20, 2019, at the Hot Chips 31 symposium Microsoft presented their Holographic Processing Unit (HPU) 2.0 custom design for the HoloLens 2 with the following features:[8]

  • 7x SIMD Fixed Point (SFP) for 2D processing
  • 6x Floating Vector Processor (FVP) for 3D processing
  • >1 TOP of programmable compute
  • 125Mb SRAM
  • 79mm2 die size and 2 billion transistors
  • TSMC 16FF+ process
  • PCIe 2.0 x1 at 100 MB/s bandwidth to Snapdragon 850

On August 29, 2019, at the World Artificial Intelligence Conference in Shanghai, Microsoft's Executive Vice President, Harry Shum, revealed that HoloLens 2 would go on sale in September 2019.[9] The product started shipping on November 7, 2019.[10]

Improvements over the previous model[]

Microsoft highlighted three main improvements made to the device: immersiveness, ergonomics and business friendliness.[11][12]

HoloLens 2 has a diagonal field of view of 52 degrees, improving over the 34 degree field of view (FOV) of the first edition of HoloLens, although Karl Guttag states that it offers less than 20 pixels per degree of resolution[13] (despite Microsoft's claim that it would keep a resolution of 47 pixels per degree[14][15]).

Holographic Processing Unit (HPU) 2.0 improvements compared to the HPU 1.0:[8]

  • 1.7x compute
  • 2x effective DRAM bandwidth
  • Improved hologram stability
  • New hardware accelerated workloads such as eye tracking, fully articulated hand tracking, semantic labeling, spatial audio and JBL filter

HoloLens 2 emulation[]

The HoloLens 2 Emulator was made available to developers on April 17, 2019.[16] This emulator allows developers to create applications for the HoloLens 2 before the device ships.
