VRFocus - Last week VRFocus reported on the news that Microsoft's HoloLens mixed reality (MR) head-mounted display (HMD) would be heading to the International Space Station (ISS) as part of a partnership between the company and NASA. The special kits will include new software known as Sidekick, designed to help astronauts with training and communication. A pair of HoloLens units were set to be shipped up to the station this month to allow for testing of this project. Sadly, those units have been destroyed in-transit after their unmanned shuttle exploded.
Microsoft seems to be struggling to answer this question, as well.
That's a total of 120,000 devices worth an estimated $21.88 billion
The HoloLens 2 comes with better visuals (and a larger screen) and is easier to use. It is also more comfortable than its predecessor for extended sessions.
