We’re Past 3DOF, Even for Casual VR Photo by Road to VRĪs the prototype exists today, the Pico VR Glasses would have been a great Daydream-like headset back in, say, 2017. Further still, the headset lacks any sensors for inside-out head, controller, or hand-tracking… which brings me to my next thought. Image courtesy Oculusīeyond using Pancake lenses, Pico’s VR Glasses also off-board most of the other components-the headset has an IMU for tracking, but it relies on a phone for compute and power. This approach has various tradeoffs, but allows the display to be much closer to the lens compared to the simple, single lenses found in most consumer headsets today.
The pancake lens approach condenses the length of the optical path by ‘folding’ it back on itself through the use of polarized light and multiple lens elements. For simple lens designs, it’s difficult to make the distance from the display to the lens smaller than what we see in headsets like Rift and Vive, which is why so many of today’s headsets feel like boxes on your face. In order to correctly focus the light from the display onto your eye, the display must be at a certain distance from the lens. Most consumer headsets today use a single, simple lens.

The biggest factor is the headset’s novel ‘pancake’ lenses, which Pico says is of their own design. Considering the headset’s ‘prototype’ designation, I won’t make a stink about for now near as I can tell, it’s a lack of final tuning rather than a fundamental issue. There was a small but notable latency to the headtracking and misalignment of the lenses which would need to be sorted out before this became a real product.
For the casual VR use-case (seated, 3DOF), it felt perfectly viable. Pico claims a 90 degree field of view on the VR Glasses, and while that sounds a bit aggressive-at least against the woefully undefined measurements touted by other headset makers-it wasn’t that far off from what you’d expect in an Oculus Quest or Rift. This is known as a ‘lens limited’ field of view, which tends to feel much more natural than a ‘display-limited’ field of view which shows a hard edge. I was impressed to find a reasonably large FOV given the compact form-factor, and especially one which filled out the entire lens rather than being cropped by the edge of the display.

In my hands-on with the headset, the viewer was plugged into an Android smartphone and ran a Daydream-like interface from which I could launch games and media.

Each eye has a 0-800 diopter adjustment for focus, and while the provided spec sheet says “51mm–75mm IPD,” I saw no physical IPD adjustment on the prototype (so this may have referred to a software adjustment only). Pico’s VR Glasses prototype employ a 90Hz, 1,600 × 1,600 LCD display in each eye, 3DOF headtracking via an on-board IMU, and a 3DOF motion controller. Pico VR Glasses at CES 2020 Photo by Road to VR
The so called Pico VR Glasses is a prototype small form-factor headset that’s designed as a ‘VR viewer’ of sorts-a lightweight, 3DOF headset designed to tether to Android phones for casual VR experiences.Įspecially considering that it’s still a prototype, it’s the most impressive ‘VR viewer’ headset I’ve seen yet, being several steps ahead in completeness over others, including a similar VR viewer that Panasonic revealed this week. But when we went to the company’s booth on the show floor, we saw a curious device sitting next to their Neo headsets. When Pico made its CES announcements earlier this week, the company talked about its new Neo 2 standalone VR headset, a Quest-like device targeting enterprise customers. This phone-tethered 3DOF ‘VR viewer’ was surprisingly complete, offering a decent resolution and field of view, focus adjustment, and motion controller in a compact form-factor that’s light enough to stay on your head. This week at CES 2020, Pico quietly revealed a prototype headset which its calling the Pico VR Glasses.
