HoloLens 2 Specs Reveal 2–3 Hour ‘Active’ Battery Life, Optional Top Strap, & More

Microsoft today revealed HoloLens 2, a standalone AR headset and successor to the original HoloLens. While the company is still keeping some specs under wraps, a list of official specs gives further insight into the new headset.HoloLens 2 was announced today boasting a field of view that’s purportedly twice as large as the original, along with a sharp 47 pixels per degree resolution, hand-tracking, eye-tracking, and improved comfort. Microsoft isn’t giving the exact resolution but says that the resolution is “2K” per-eye with 2.5K light points per radian; which works out 47 pixels per degree, which we understand to be the same pixel density as the original headset (very sharp compared to contemporary consumer VR headsets). On stage at the reveal, the company made the point that they’ve maintained 47 pixels per degree despite more than doubling the field of view of the headset. The specs note a 3:2 aspect ratio for the display which is more square than the original headset’s 16:9 ratio. 3:2 is arguably a better shape for an AR headset because it distributes the display more evenly across the horizontal and vertical portions of our vision, though which is best ultimately depends on the use-case.
