Sharp announced it’s launching a crowdfunding campaign for a slim and light PC VR headset in Japan, called Xrostella VR1.

The News

Sharp first showed off a PC VR headset prototype at CES 2023, which was supposedly meant to ship sometime in 2024. It’s been nearly three years since we last heard about the headset, however during a recent Metaverse Expo in Japan, Sharp unveiled a newer version of the device, as demoed by Gizmodo Japan.

Now, Sharp says it’s slated to sell the device in Japan via crowdfunding platform Green Funding starting sometime in November, which it’s now dubbing ‘Xrostella VR1’.

Xrostella VR1 connects to either a Windows 11 PC or a limited number of smartphones via a wired connection. The company has confirmed compatibility with Sharp’s AQUOS sense10, with more models soon to be revealed.

Weighing in at just 198g and sporting what Sharp calls in a Japanese language press statement a “glasses-like design,” the headset includes dual 2,160 × 2,160 per eye LCD displays clocked up to 90Hz.

It also makes use of “thin, light-efficient pancake lens,” providing a 90 degree field of view (FOV), and cameras for both inside-out 6DOF tracking and color passthrough.

Included controllers appear to be a standard ‘Touch’-style affair that shipped with Quest 2 in 2020, replete with tracking rings, which comes in stark contrast to the company’s recent controller prototype, which combines standard button input with a unique haptic glove.

Additionally, Xrostella VR1 features a mechanism for adjusting the interpupillary distance (IPD) and diopter from 0D to -9.0D, which will allow nearsighted users to wear without needing glasses.

Pricing has yet to be confirmed, however Gizmodo Japan speculates it could be “more expensive than the Meta Quest 3,” which is priced at ¥81,400 (~$530 USD).

My Take

If you saw the specs and did a double take, you’re not alone. While having independent diopter adjustments is cool, it’s a shame Sharp is going so weak in the display department, as it essentially delivers a resolution only slightly higher than Quest 3.

And while the form factor is interesting on paper, I have my doubts that 198g will weigh lightly on the bridge of your nose without having some sort of strap you can crank down, or otherwise better distribute weight for longer sessions—making its ‘glasses’ form factor more akin to headset with rigid, non-configurable straps. It all smacks of an aging headset design, recalling devices like HTC Vive Flow (2021), which feels remarkably heavy on the face, even at 189g.

Granted, marketing images don’t show the buckled strap system seen below, so there’s no telling what it will ship with. But the fact the company was demoing with the strap tells me everything I need to know about just how front-heavy it will be.

Still, it may not be as ‘DOA’ as you might think despite the thin and light PC VR segment growing to include a bevy of devices: Bigscreen Beyond 2 ($1,020), Pimax’s Dream Air SE ($900 – $1,200) coming December, and fellow Japanese brand Shiftall, which is releasing its latest MeganeX PC VR headset in December too for $1,900. It could be significantly cheaper if it were closer to Quest 3 in price, which would be really interesting to watch.

That said, Sharp’s VR headset is likely going to be a Japan-only device, which means the company will probably be leaning hard on the fact that it’s being produced and serviced domestically—regardless of price.

While mostly known for televisions and home appliances in the West, Sharp actually holds a significant slice of the smartphone market share in Japan. Despite foreign brands like Samsung and Google making recent headway in the country, Sharp remains a trusted name that Japanese consumers may simply feel more comfortable dealing with.

    Sharp Corp is doing a crowd funding ?

    I stopped reading after LCD

    • XRC

      $2.7 billion market cap

      and they use crowd funding?

      • LOL yes

        • XRC

          "On the crowdfunding service "GREEN FUNDING" operated by Onemore Co., Ltd., we will start recruiting supporters after the end of November this year."

      A lot of companies now use crowd funding primarily as a marketing tool, not a way to pay for the development itself, giving incentives like early bird special prices, and counting on word-of-mouth news spread. A lot of 3D printer companies still use sites like Kickstarter only for this reason, despite the product having already been completely developed, and the company behind it not needing the extra cash upfront.

    It also makes use of “thin, light-efficient pancake lens,” providing a 90 degree field of view (FOV), and cameras for both inside-out 6DOF tracking and color passthrough.

    The "light-efficient pancake lens" might be the most interesting part, as pancakes as used in current HMDs are horribly inefficient, losing up to 90% of the light coming from the display, compared to only about 15% in aspheric/Fresnel lenses. This is not due to the pancake configuration itself, which just means several lenses are placed in a row, like in zoom objectives that are usually very light efficient.

    But in HMDs, the single lenses are specially coated to either let light pass through the lenses, where it will be refracted/bend at the glass/air barriers, or have it reflected back. What happens depends on the current polarization of the light, so there is a series of reflections/refractions/polarization changes that make the total length of the light pass through the pancakes much longer, allowing for thin HMDs, but also losing a lot of light at every step.

    This comes with high energy costs, as you now have to use much brighter/power hungry displays usually needing active cooling, just to achieve similar visible brightness levels as Fresnel/aspheric. This currently limits pancakes to bright LCD or microOLED, excluding OLED panels like in the PSVR2. So if Sharp have indeed come up with a way to create a “thin, light-efficient pancake lens”, this might open up the road for something like a cheap Quest 4S using relatively cheap OLED panels with pancakes for both high contrast and edge-to-edge clarity, without having to pay a high premium for using microOLED displays.

    Meta quest 3 is great ever

  • foamreality

    I read 'LCD' and stopped reading the rest of the article. Its not 2016.

    VR has become a bubble that never expanded. VR has barely moved on, just different configurations of a high PPD and everythign else which has barely improved since OG VIve, which is still better than half the latest headsets released today. No OLED is s joke, 80 degree fov is a bigger joke, mobile graphics of quest is all 3 jokes.
