The Display Resolution of Head-mounted Displays

Doc-Ok

What is the real, physical, display resolution of my VR headset? I have written a long article about the optical properties of (then-)current head-mounted displays , one about projection and distortion in wide-FoV HMDs , and another one about measuring the effective resolution of head-mounted displays , but in neither one of those have I looked into the actual display resolution, in terms of hard pixels, of those headsets.

Accommodation and Vergence in Head-mounted Displays

These are another two (relates ones) of those frequently-asked questions about VR and head-mounted displays (HMDs) that I promised to address a while back. Figure 4: A pair of eyes looking at a virtual object in a head-mounted display. Why do virtual objects close to my face appear blurry when wearing a VR headset? My vision is fine! And why does the real world look strange immediately after a long VR session?

Nintendo Files Patent For New Labo VR Headset

VRScout

Discovered first by Let’s Go Digital , the patent—entitled ‘3D image display system and 3D image display device,’ features concept art of a head-mounted display similar to that of the Labo VR Goggles. Like the original cardboard goggles, this new rendition would not include a head strap, instead requiring users to hold the goggles up to their faces by grasping either the goggles themselves or the Joycon controllers.

Head-mounted Displays and Lenses

Doc-Ok

” The popularity of Google Cardboard , and the upcoming commercial releases of the Oculus Rift , HTC Vive , and other modern head-mounted displays (HMDs) have raised interest in virtual reality and VR devices in parts of the population who have never been exposed to, or had reason to care about, VR before. What this means is that, for most people, it would be impossible to focus on the screens of HMDs (unless the display is ridiculously large ( source )).

Measuring the Effective Resolution of Head-mounted Displays

Doc-Ok

So, why do current-generation head-mounted displays appear so low-resolution? What counts is not the total number of pixels, and especially not the display’s resolution in pixels per inch , but the resolution of the projected virtual image in pixels per degree , as measured from the viewer’s eyes. It’s a good idea on paper, but the tricky bit is that it tries to measure not what a display objectively displays, but what a viewer subjectively sees.

The Display Resolution of Head-mounted Displays, Revisited

Doc-Ok

I wrote an article earlier this year in which I looked closely at the physical display resolution of VR headsets, measured in pixels/degree, and how that resolution changes across the field of view of a headset due to non-linear effects from tangent-space rendering and lens distortion. The first two figures, 1 and 2, show display resolution in pixels/°, on one horizontal and one vertical cross-section through the lens center of my Vive’s right display.
