Sol Reader Is a VR Headset Exclusively For Reading Books (techcrunch.com) 92

A company called Sol Reader is working on a headset designed exclusively for reading books. "The device is simple: It slips over your eyes like a pair of glasses and blocks all distractions while reading," reports TechCrunch. From the article: The $350 device is currently on pre-order, comes in a handful of colors, and contains a pair of side-lit, e-ink displays, much like the Kindle does. The glasses come with a remote (I wish my Kindle had a remote!) and a charger. A full battery gets you around 25 hours of reading. That may not sound like a lot, but if you have an average adult reading speed of around 200 words per minute, you can finish the 577,608-word tome Infinite Jest in about 48 hours. That means you need at least one charging break, but then, if you are trying to read Infinite Jest in a single sitting, you're a bigger book nerd than most.

The product has a diopter adjustment built in, so glasses- and contacts-wearers can use the glasses without wearing additional vision correction (up to a point -- the company doesn't specify the exact adjustment range). The displays are 1.3-inch, e-ink displays with 256x256 per-eye resolution. The glasses have 64MB of storage, which should hold plenty of books for even the longest of escapist holidays.

The company's $5 million funding round was led by Garry Tan (Initialized, Y Combinator) and closed about a year ago. Today, the company is shipping the 'advanced copy' (read: private beta) of the glasses to a small number of early access testers. The company is tight-lipped on when its full production batches will start shipping, and customers are currently advised to join the waiting list if they want to get their mittens on a pair of Sols.

      I don't think you could pay me enough to put on a headset with only 256x256 resolution in each eye. And 64 MB of storage? 2003 called and wants its flash memory back! A current-gen Kindle has vastly higher resolution, 250 times the storage, and costs less than a third what this headset does. The "VR" buzzword doesn't make the value proposition.

      • The resolution is definitely an issue. I'm just talking about the concept.

        If I'm doing my math correctly 256x256 pixels on a 1.3" (0.92"x0.92") screen works out to ~278ppi, just a shade lower than the 300ppi common to most current gen ereaders like the latest Kindle Paperwhite. If fact I am unaware of any e-ink device offering more than 300ppi. That said you're generally not holding up a Kindle anywhere near as close to your eyes as these glasses will be so every pixel will matter, these just won't have anywhere near the pixel density you'd need for something getting that close to your eyes to have the same subjective density as something held at a more typical book-reading distance.

          You're not looking directly at a 1" display, you're looking at a magnified version of it - the equivalent of an 8" or 10" display, which knocks it down to "1970s Apple II with a 40 column CRT" territory.

        • by Cinder6 ( 894572 )

          Your math is right, but it's still only a 256x256 display. To put it in comparison, the current Paperwhite has a 1236x1648 at 6.8"—roughly 3,000% more pixels. And eInk has a "refresh rate" in the single digits per second, not the 90+ you'd want from a VR setup, meaning you can't just get away with relying on the user turning their head to see more text.

          As others pointed out, the relevant measure is not pixels per inch but pixels per degree. A "retina" display, which has pixels small enough that standard eyesight can barely distinguish them, should have about 60 pixels per degree -- and this 256x256 display will span a lot more than 4 degrees of view.

          Another way to think about it: The resolution of 300 ppi is similar to an old or low-end laser printer. Would you want to read a book printed on 0.9"-by-0.9" pages, even if you had a good magnifying glass or

      • Storage is kind of a minor concern for a book reader. Now, I wish it did graphic novels... but for books, they're probably around a megabyte or less. Are you going to be reading 64 books at a time. Throw five books on it, read them then get some more.
        • by Shaitan ( 22585 )

          It just doesn't make any sense. Storage is so cheap at this point at $350 you'd expect substantially more, or they should have added $20 and tossed another gig in there. First even at 1mb a pop this definitely wouldn't hold my kindle library and second you are forgetting audio books.

          64 MB does not seem so reasonable to me. My Kindle shows 396 MB used by 95 "items". $2 will buy somewhere between 1 GB and 16 GB of flash, depending on packaging (flash drive on Amazon to spot price for bare flash module), so how does a $350 headset justify not spending a buck or two for a huge increase in storage capacity?

        The benefit of a wearable over a handheld is this: One is wearable and the other is handheld.

        Holding something in your hand requires the use of your hand, which dictates the entire posture of your shoulders, neck, and spinal column, for hours at a time.

        Why would people want to wear corrective contact lenses or glasses instead of just carrying around a handheld magnifying glass they can hold up to anything they wish to see in detail? Contacts/glasses seem like an odd niche device, yes?

      If you go to their website (solreader.com), in the middle of the page there is a picture of glasses and if you click on Navigate, you get a closeup. You weren't much off - font seems to be 8px tall, but it is variable width, so a is around 5 pixels wide, which allows slightly more words in one line.
      It is still pretty horrible quality-wise. Plus, their claim that they cost only 10% of apple headset, instead of saying 'we cost the same as Oculus Quest 2, at 10% of capabilities'...

To read a line of these insanely HUGE letters, you'd have to move your eyeballs almost completely from left to right.

        If you want to have the "realistic experience" of what it's like, put your face right onto your screen and try again. This is a horrible experience.

        Your argument is like saying the "Kindle Paperwhite" is not worth because it's the same price as a "Samsung Galaxy Tab A8" and has more limited capabilities. Their device version 1 is underwhelming, but their idea is clearly different than Oculus which is marketed for games (from what I get on their website).

    If you have a DRM-free (.epub) library, you can simply load the books up in the Sol Reader using the Sol mobile app.

    Most of the people checking this out are not going to be e-book geeks and know whether the items on their kindle shelf are epubs or not. They'll have no idea if the books are even DRM-free or not.

    Or, you know, associated with people who do?
    For fun. As this is clearly useless for anything where you have to study the material, keep notes, copy text etc.

    At that price range, they are clearly aiming this at the 30+ crowd with hefty disposable incomes which allow for ANOTHER gadget strictly for reading books, at nearly three times the price of a Kindle Paperwhite, without ads. [amazon.com]
    Meanwhile "diopter adjustment built in" is described by TFA as "up to a point - the company doesn't specify the exact adjustment range"... which isn't actually true - TFA is crap.
    Site claims the optics to be "0 to -5.75 diopter adjustable" - i.e. if you need reading glasses [wikipedia.org] or if you need glasses for walking [wikipedia.org] - you'll probably have to wear contacts to use this.

    Should you be one of the lucky ones and not need eyesight correction, this does not allow for eye rest during reading - without taking the whole damn blindfold off.
    There's nothing to refocus your eyes to.
    I.e. Say hello to eye strain, maybe migraine, maybe neck pain, itchy eyes... Sing it with me!

    Jesus fucking eye-gouging Christ... [sanity.io]
    Are these people [twitter.com] secretly time-travelers from 1890s, trying to amaze us with their idea of illuminated print goggles?

    On top of that, that thing is so THICK, presumably most of it going towards battery space to power THE GOD DAMN E-INK DISPLAY WHICH DOESN'T REQUIRE POWER TO STAY ON!
    Meanwhile, that's still just two built-in 235mAh - 470mAh rechargeable lithium-ion batteries, probably something like this. [aliexpress.com]
    I.e. Up to 940 mAh, for ~25 working hours - compared to Kindle's 890 mAh [newpower99.com] 15 to 20 DAYS of actual use or 2 to 3 days with Wi-Fi on.
    While the remote still requires a goddamn CR2450 and is designed to be lost as a fucking strap would ruin "the design experience". But don't worry, a replacement will set you back only $45+shipping.

    BUT... the thing has side lighting so you can have LED lights burn your retinas - ergo only 20-something hours of battery life compared to Kindle's weeks. [thebookbuff.com]

    The reasoning clearly being that some fucking psychopath with various untreated mental issues but still in charge of directing the design believes that blinkering of the reader (the human, not the device) is necessary in order to prevent distraction while reading.
    Which brings us back to the question - do these people read books or know anyone who does? You know... for fun.
    Simply making this thing translucent to ambient light, or if that's too difficult to design then adding slits with prisms for directing light for that "side lighting" effect, which would make this thing easier on the eyes, longer lasting when used and cheaper to produce.
    Instead, it has sensors to adjust the LED light to ambient light... but it will still be only that ugly 3000K yellow LED light.

    256x256 resolution sound so much like a joke I had to double check. Cheap e-readers are at 800x600 resolution and it is usable but not great. 256x256, that's comparable to a C64, which wasn't really designed for text, even back in the days. There is no mention of the FoV, but either it as tiny as a post-it note, or you are going to get massive pixels.

    I also see they are using e-ink displays. The great thing about these display is they look great with an external light source, but in a VR headset, you can't take advantage of this property, so is it worth it? Especially if it is the reason for that puny resolution.

    But who knows, maybe it is not that bad. It is a first, you don't know until you try. I am particularly interested in the optics. Traditional VR headsets focus so that you are comfortable looking at infinity, but that makes them terrible at a typical reading distance, this headset will presumably have optics optimized for reading.

    That isn't very much. That is maybe 1-3 books.

    • You must be thinking of pdf files, which this is not for.

      epub books tend to run from about 100k for a "novella" up to maybe 1mb for a really long book. In many cases the size of the cover graphic is bigger than the html files that make up the actual book text and you can reduce that easily since an epub file is really a zip file.

      So 64mb of storage will get you at least a few hundred books depending on text length and cover sizes.

        I can squeeze 4 on this device. Not very many.
        • I've never seen an epub file that big. Are they really graphics-heavy or something? Or do they contain embedded font files? I suppose either of those could create a blown-up epub file like that.

          Novels tend to be in the 200-500k range, depending on the length of the text unless they have a huge cover graphic or embedded fonts.

    • That isn't very much. That is maybe 1-3 books.

      Here are some stats from my library of epubs. Most are novels, some are short stories.

      1292 epubs, all with at least a cover image.
      average word count pr. book is 109 000.
      Average file size 719 kb.
      My very largest book is 22MB (Mistborn by Brandon Sanderson), that one has quite a few illustrations
      only 10 books out of all 1292 are larger than 10MB.

      As for your file sizes, I suspect that the newer Kindle formats are quite inefficient, converted to epub (which is basically zipped html+css) they should be much small

        This is incorrect. Minus a handful of reference books and my comics, everything I have is epub.

  • Can you imagine trying to read in bed with that thing on? I already have to find reading glasses with bendy arms to read in bed so they don't dig into the side of my head. Try me again when there's a Pince-nez version.

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
