History

HoloLens 2 was announced by Alex Kipman on February 24, 2019 at MWC in Barcelona, Spain.[1][2] On May 7, 2019 the HoloLens 2 was shown again at Microsoft Build. There, it showcased an application created with Unreal Engine.[3]

On August 20, 2019, at Hot Chips 31 Microsoft presented their Holographic Processing Unit (HPU) 2.0 custom design for the Hololens 2.[4]

  • 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 will go on sale sometime in September 2019.[5] The product started shipping on November 7, 2019.[6]

Improvements over the previous model

Microsoft highlighted three main improvements made to the device: immersiveness, ergonomics and business friendliness.[7][8]

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, while keeping a resolution of 47 pixels per degree. [9][10]


Holographic Processing Unit (HPU) 2.0 improvements compared to the HPU 1.0[4]:

  • 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. [11] This emulator allows developers to create applications for the HoloLens 2 before the device ships.
