Storm around Microsoft’s HoloLens 2: Field of View Exposed

What is the controversy and why?

At MWC 2019 yesterday Microsoft launched HoloLens 2 stating how improved the field of view is i.e. 52 degrees, when compared with HoloLens 1. But there was no mentioning of what it just means. In answer to this Alex Kipman (Technical Fellow for AI and Mixed Reality) on Twitter clarified the detail. The headset provides 52 degrees diagonal viewing of augmented reality.

How was Alex Kipman able to explain the details?

Microsoft site mentions headsets aspect ratio as 3:2, this would give horizontal FoV of 43° and a vertical of 29° using the basic Pythagorean theorem.

Does this mean Microsoft lied about improved field view?

According to Pythagorean theorem used by Alex Kipman it might seem that Microsoft lied. But if we look at a broader aspect it looks as like Microsoft was referring to total FoV area not the per-axis measurement. Because A 43°×29° FoV is around 2.4x the area of 30°×17.5°.
