Understanding Pixel Density & Retinal Resolution, and Why It’s Important for AR/VR Headsets

While most of us are used to dealing with resolution figures that describe pixel count (ie: a 1920×1080 monitor), pixel density stated as pixels per degree is a much more useful figure, especially when dealing with AR and VR headsets. Achieving ‘Retinal resolution’ is the ultimate goal for headsets, where at a certain pixel density, even people with perfect vision can’t discern any additional detail. This article explores those concepts, and takes a look at how far today’s headsets are from retinal resolution.
