Electronic Paper's Past and Future
Iddo Genuth sends us to TFOT for his extended series of interviews around the question of how electronic paper will change our lives in the next few years. The article leads off with the "father of e-paper," Nick Sheridon, who came up with the idea almost 35 years ago at Xerox PARC, and goes on to explore how e-paper may evolve past its current incarnations in the likes of the Sony Reader.
I've heard good things about them, specifically the battery life. Does anyone own an E-Reader? I was thinking of getting Sony's. Any thoughts?
the question of how electronic paper will change our lives in the next few years.
Two words: porn.
The theory of relativity doesn't work right in Arkansas.
personally, i'm really interested in this whole e-paper movement, whatever it is. It has an e at the front so it's hip.
Help Me! I'm trapped in the tubes! Oh noes! Here comes a internet!
Can I still write on it?
If you build it, nerds will come. Soylentnews.org
...electronic rolling paper. Maybe some electronic hits while I'm at it. Creepy, it's been years since I've seen stamps dancing on their own...
It is dangerous to be right when the government is wrong.
From TFA:
Q: When do you predict we will see the real e-paper revolution?
A: It has already started but will become a real mass market in about 2012.
So that 's what the Mayans were worried about!
Ahhh, what an awful dream. Ones and zeroes everywhere... and I thought I saw a two.
When the display can be folded and put into a pocket, when I am able to read all of it on a single charge, when I can effortlessly pull down background info from varied sources - let me know, I'll be buy 10 of them.
I see that bookster.com is already register. Even the pirates are planning ahead.
Hopefully, this copyright/piracy controversy will be straightened out by 2012, or authors will be joining musicians in the welfare lines of Tomorrow.
You missed a great opportunity, so I had to correct it for you. :)
Rumors are flying around that Amazon is going to release their own e-ink device any day/week now. A version of it went through the FCC a while ago since it might have a wireless modem in it. It will probably be more expensive than the Sony, but might have the ability to download newspapers and magazines directly.
Bookeen is coming out with their own device any day now that's really similar to the Sony reader but will use different file formats. They all read RTF, TXT, etc... but if you want to buy a new book, it's likely to have DRM in the file. The DRM file format that the Sony uses is different from the DRM files that the Bookeen and Amazon Kindle will use.
The Iliad is bigger and can render letter size PDF files without the hassle of the smaller devices. It has wifi and a writable screen that you can take notes with... but it's supposed to be slower and more than twice as much money.
I want one really bad, but I'm waiting to see what Bookeen and Amazon finally release before I throw down my cash. Sure they're all kind of expensive, but you can load up with free classic books from Project Gutenberg and you'll save money in the long run (if you read a lot and are too lazy/busy to make trips to the library).

I think durability will be the biggest problem.
People are rough with things. Especially students, one of the ideal user groups for this kind of thing.
The low-power portion is desirable, but my guess is that most of these things will end up in frames.
Oh, and if, as is mentioned in the article, they have some sort of promotional giveaway of e-paper with ads/slogans etc... grab one quick!
:)
They'll stop giving them away when a "hack" appears online to add battery life, memory, rewrite the OS, etc.
I'm actually not sure that stable-image type displays (what I would generically consider e-paper) are going to be the first widespread paper-replacement. As nice as their low power consumption is, their bit depth, color, contrast, and refresh rate are all horrible at the moment. And while they are certainly improving in those areas, things like LCDs and OLEDs are improving in power consumption and form factor as well.
I came to this realization when I looked at the new 505 revision of the Sony Reader's marketing, and it occurred to me that I'd rather get an iPod touch. Recharging every few days instead of every few months is a sacrifice I'd be willing to make for real web content and video (while Sony could probably put some sort of basic very-static web browser on it's reader despite the display's low refresh rate if they wanted to support HTML, video and quick interactivity are going to be out of the question until there are fairly major changes in the display technology). And, as more and more content moves online, from static paper to dynamic computer screens, moving content is only getting more prevalent (rollovers, pull-down menus, AJAX widgets of all sorts, and even content in flash and other plug-ins)...
I kind of suspect that e-paper has missed the window where it could have widely succeeded with a refresh rate measured in seconds rather than milliseconds. Stable-image type displays may have to get their refresh rates down into the low-double-digit milliseconds (and coincidentally gain high bit depth color and decent contrast) before they can take on to the mainstream.

The Sony's PRS-505 is at $299. I will wait until the price drop to 199. I have seen the epaper made from E Ink, it is very easy on the eyes and the latest Sony ebook has made a significant advancement in the refresh rate.
There are tons of copy right expired content online. I can't wait to curl up on the couch and read a good classic novel.
The purpose of writing is to inflate weak ideas, obscure poor reasoning, and inhibit clarity....Calvin
I don't think epaper will make a huge difference in our life in the years to come. The biggest reason is that it's overpriced. A laptop is a good example. Laptops go from $400 to thousands. On the upside, they will save you money after you have used at least 400000 (four hundred thousand) sheets of paper roughly. It is also more environmentally friendly and efficient. Not to mention more organized and smaller! However you've also got battery life... It works just as well without the price and no batteries required. If you could make some sort of pocket book that had an easy input method such as a widely sold stylus and a battery life lasting at least 200 hours on full power. I think for now I will stick with good old fashioned paper.

Quit telling me when it's coming, gimmie it now.
Personally, I am waiting for Sony to release their clear plastic imaging technology for this purpose. I believe that once the Japs get their DRM controls a little more liberal, then all of can start making leaps past the wet dreams of an iPhone.
WWPD - What Would Picard Do?
Great, we've managed to replicate yet another crappy input device which is still many levels below direct neural interfacing. Seriously, we're almost 2010... c'mon guys, I'm not lashing out until the Logitech (TM) Direct Neural (TM) connection hits the shelves. And cerebral subprocessors... I mean, I'm still trying to do maths with my woefully inadequate brain - and why can't I use Google by thinking about it??
People from 20 years in the future will laugh at us for our crappy IO devices. Still, they'll all be wearing badly done external implants. Now the people of 100 years in the future with internal bio-processor implants, I'm really jealous of.
Best gadget I've ever bought. _SO_ good. Fictionwise have the rest of the stock and they've rebranded it, but its the same (awesome) device.
Yay me!
First of all the PDF functionality is non-existent despite the claims. However the .doc .txt translation is fan freakin tastic. Pictures are pretty crisp and the major bugs with it were patched. I imagine sony has some evil rootkit what have you on my computer, but quite honestly the program hasn't done anything I can think of as invasive, and other than being a little slow it's ok.
Right now I have a slight gripe with the browsing ability on the reader itself when there are lots of books or documents on it. The ability to magnify documents and books is also really nice and it is really easy on the eyes. This is definitely still first gen hardware, so you can wait for better, but honestly this thing keeps me sane on train travel, airplanes, etc. I often just copy whole online articles, paste them in word, and then browse at my leisure on the go.
You missed the point. E-paper as the name implies isn't a replacement for computer screens. It's a replacement for a printed paper as in newspapers and books. Most of the people still get their knowledge from dead trees and e-paper for them is more or less just like paper, only better, since you can "print" on it many times.
I am an avid ebook reader using Palms for the purpose for years, but as soon as I can get an e-paper reader without stupid limitations at a reasonable price (which for me is anything south of 250eur), I'll go that route. I mean, that would be the best of both world: paper book with the ability to (non-destructivelly) bookmark, annotate, search, copy text at will.

I've heard about e-paper and the way it's going to revolutionize our lives for about 5 years now. I've never seen one device that has it, and I've only heard about this Sony thingy so far. If this stuff was really so good other manufacturers should have embraced it by now and we should have a hard time avoiding it, no? For me e-paper is just like Linux on the desktop: always just around the corner.
-- Cheers!
Other than a specific crowd that will purchase anything neat (and I am very much in that group) who cares about any of those issue?
To largely replace paper books we need a minimum of large size, lots of contrast, rugged construction, light weight, and generally usable anywhere for long periods of time. We are no where *near* that. Add in cost and being able to make marks on it being a requirement for many applications and we have some real issues.
Size, rugged, and battery life do not go together. I need something I can carry in my car, backpack, or just mostly leave lying around and not have it break or get scratched to the point of unusable. I need to be able to expect to take it to most places I go and have it work *and* be readable at the same time - having to have it plugged up every 10 hours is, in many cases, unacceptable.
That is only concerning replacing books, let alone paper. Can I fold it and stick it in my pocket? Will I care if I happen to destroy it? If I can't stick it in my pocket what good does it do me? If I can't carry it in any place other than carefully controlled environments due to its cost - again what good does it do me? Heck, if I can not make a note and give it to someone else that doesn't have one what good does it do me? Everyone on the planet isn't going to carry around their e-paper (which can not be folded, carried in their pocket, exposed to water, exposed to much shock, exposed to high/low temperatures, and all the other things any current or foreseeable future technology has to offer).
E-paper has not come close to its window - it hasn't even come close to the point that most people would seriously look at it. Heck, even the totally made up stuff we saw in Star Trek didn't really replace paper books, let alone paper. That's not to say it will not happen (I think it will), but anything I have remotely seen companies working on do not come close to meeting the requirements to replace paper. They are trying to force books/paper into existing technology and technological paradigms instead of trying to make electronics work like books/paper.
------- Sorry about the spelling, I suffer from two problems. Dyslexia makes it difficult to spell well, lazy makes it
Change our lives in the next few years (hey that is what the article says, blame the editors)? Might be tricky, since we don't actually have e-paper available right now, and no clear date when it will be either, how exactly is it going to chance our lives?
THE BLOODY STUFF DOESN'T EXIST YET.
I am sure a cure for cancer will change our lives, but it doesn't exist yet, so it won't be in the next few years.
Real paper is incredibily cheap and can be easily recycled, do we really want to replace it with something that is more expensive, and can't? I for one can't really see the benefit of having e-paper used to package my groceries.
As for e-books, well we all know how well those worked right? The problem is simple, the readers just ain't books (too expensive and well just not books) and the contents are too fucking expensive. Just because we pay a premium for paperbacks does not mean we will pay the same for a tiny amount of data.
Books unlike say CD's got tremendous extra value for some reason. Maybe it is because most bookstores don't blast our ears with crap music that the idiot behind the counter happens to like, and most bookstores actually bother to hire people who like their job. I like going to my local bookstore, the musicstore BAH.
Simply put the problem is that we don't "mind" the price we pay for our fiction right now. Especially since the alternatives ain't realistically priced. Uploading less then 1/10 of a MB to me does NOT inspire me to pay EXACTLY the same amount, if not MORE then for the dead-tree version. Why yes, I do think the Apple is ripping people off with iTunes, why do you ask?
I can see the costs of producing a dead-tree copy I buy in a brick&mortar store, I can't see them in e-book websites. WHERE ARE THE HUGE SAVINGS GOING? Savings in having to print books, stock them, distribute them, stock them again, take unsold copies back, etc etc. WHO IS RAKING IN THE CASH? Wanna bet it ain't the author?
So I am left with a very expensive reader, that can't stand being wet, or being sat on or having the cat sleep on it (my cat is a bit old and sometimes wakes up a bit too late), I don't think bleaching the wet spot works well on electronics) that if I forget it, I am out NOT just the reader but ALSO the collection of books, so I have to rebuy them at EXACTLY the same price as the dead-tree versions.
LOWER THE GODDAMN PRICE! That is when e-paper will change our lives.
The only way I can see this taking off is combined with the move to make textbooks freely available. Give each student an ebook reader, publish the textbooks online for free and voila, huge savings to education.
But if e-books continue to be sold at 20 bucks for fiction, then no, it won't take off.
MMO Quests are like orgasms:
You may solo them, I prefer them in a group.
So in the future, we can have e-voting machines which leaves an e-paper trail for accountability!

The prefect situation for me would be to have a e-paper module added to the top of a small laptop lid. That way i can read any documentation off the back of the laptop without having to even turn it on. You can cache emails, webpages or anything that you need to read from the laptop while its on and read it later from the lid.
sweet. I'm gonna love this e-papper era.
... we are going to cut down even more trees...
I'm not a tree hugger as trees are just crops that take monger to harvest, but the point is clear.
"My main thought is that since it's by Sony it'll be drenched in poisonous DRM."
As opposed to the analog DRM that books presently enjoy. Yes one can copy books, but technology makes the copying of digital media much easier than analog.
"The only place ebooks have a decent chance of success is to replace the two tons of textbooks most schools require their students to carry. Otherwise it's hard to beat the convenience of Dead Tree Format."
As someone who had to move and give up a lot of books in the process. I'd say it's for more than just textbooks. Bibliophiles would enjoy the convenience of E-books and E-paper. The effects piracy will have on that dream remains to be seen.
"Because musicians are hurt so much by piracy. "
It's not about "hurt", but loss of trust and respect. That "hurts" enough.
"Oh wait, no they're not"
No one here has been able to conclusively prove that it benefits either.
"The small ones freely allow others to copy and distribute their music while the big ones are still making more then enough to support their coke habits."
Piracy is based upon "lack of permission". The big one's have a big stick and lots of padding that the small guy doesn't.
"Guess authors don't have so much to worry about then."
If an author decided to go into another line of work due to piracy?* Then everyone should worry instead of assuming that authors like being treated the way piracy treats them and they will continue to accept it no matter what.
*Much like a FOSS author no longer writing due to repeated license violations with a "whack a mole" attitude public.
I bet you won't be able to light a campfire with your e-paper.
There is another Reader on the market, though it's much less famous. I can't find an English page about it. But it's cheaper than the Sony PRS.
And a review says its functionality is also better. Unfortunately the review is also in Russian
I have two models, V8 - which doesn't have an OS and runs on Epson cpu and V3 - that runs LINUX and runs on ARM 200mhz processor.
Both are great. Both have MMC/SD card, no DRM. V3 can display PDF and DJVU files. Both have SDKs for you to tinker with. While V8 is very basic and you have to use ANSI C to code your things, V3 is somewhat more powerful.
Nevertheless, as a reader, I prefer V8, because it has cover built in and an additional small display :) and I do most of my reading in FB2 and TXT.
ePaper etc always seem 'just around the corner' - until then a cell phone works great as a book reader. The screen is 'not perfect' but the ubiquity sure is.
Having recently tried to find a company that could sell me any economical form of electronic paper I can tell you it's damn near impossible. I had a special project I wanted to use it in. I didn't need color or high resolution. I just needed a really cheap, low power, thin, flexible, screen. The best response I got offered me a tiny bit of paper for around $3500. Hardly the stuff they could be making cereal boxes out of. *sighs*
At what price learning? At what cost wisdom? The price is a man's peace of mind, and the cost is his life.
Seriously. With e-wallpaper I could change the entire look of my house without having to pay decorators, move furniture or get paint/wallpaper paste all over the carpets.
With the added bonus that if I don't like how it looks, I'm not stuck with it until I can afford the time/money to do it again.

Fast-forward several years. "Browsing devices" are the "VHS moviecams" to epaper's version of Polavision. Before anyone starts ranting against web-browsers, let me point out...
- the ORIGINAL web, as developed at CERN, was text-only with browsers like lynx
- you can read files on your local drive with Firefox or IE or Lynx
Note that I said "browsing devices", not PDAs, or micro-laptops. I think that cellphones with browsers are going to be far more of an epaper-killer than laptops...- there are a lot more people already lugging around cellphones/smartphones than will ever buy single-purpose "ebook readers"
- many cellphones/smartphones already have browsers built-in
Which do you think the average person WHO IS ALREADY LUGGING AROUND A CELLPHONE/SMARTPHONE more likely to do for casual reading...- buy yet another $200 device that they have to lug around, or
- use the cellphone/smartphone THEY'VE ALREADY PAID FOR AND THEY'RE ALREADY LUGGING AROUND to accomplish the same task
In a world where cellphones/smartphones/PDAs do not exist, a $200 stand-alone "ebook-reader" might have a market. In today's world, fuggedaboutit. Most people will end up sticking a USB stick into a cellphone/smartphone/PDA and reading text directly with their browser. Verizon subscribers, however, will find that their cellphones are crippled, and they have to upload the file to their account, and Verizon will charge them by the kbyte for the uploads.I'm not repeating myself

.rtfs is _awful_, allowing widows and orphans and pages to end on a hyphen .pdfs which break at a line end become two distinct hyperlinks (this may be a problem in how the user guide .pdf was created)
.pdfs especially for this and leave page numbers off?
The local Borders store set up a display w/ one of these yesterday and I spent a while playing with it. Initial impressions:
- nice size, _very_ thin
- crisp, sharp greyscale display --- very readable
- uses GPL software (there's a list of utilities in the user manual as well as notes on where to d/l the source for the software)
- decent interface w/ sensible buttons and okay layout
- supports pdf, txt, rtf, bmp, jpeg, gif and png files as well as the proprietar? BBeB books (.lrf and
- plays mp3s
- switches from portrait to landscape and back quite easily
- nice magnification mode
On the downside:
- ~2--3 seconds to switch from one page to another sometimes one gets a distracting flashing
- sometimes one gets ``ghosting'' if the new page has a lot of white space where text or image was before
- the text H&J when displaying text files and
- the font used for displaying rtfs uses oblique, not italic for emphasis
- sidebars of some of the text font characters, ``i'' most egregiously is not good resulting in poorly spaced text
- urls in
- while one can play an mp3 while reading, controlling the mp3 functions require going all the way back to the main menu --- would've been better to've over-ridden the number buttons for use as audio controls while an mp3 is playing.
One can't help but wonder if the status bar at the bottom can be turned off --- it displays a persistent page number --- perhaps people will format

Apparently this is an updated model and the text updating used to be even slower.
Borders didn't seem to have a mechanism for selling BBeB books in their stores though which is strange since they can be stored on memory cards (Sony proprietary sticks and SD memory cards).

Sphinx of black quartz, judge my vow.
Throughout my university years, I've consistently sold my textbooks for 90% to 95% of original price (after having bought them new from the bookstore). Two main things I did: first, I treated my textbooks very nicely; second, I found a student who was in the year behind me, and basically consistently sold my textbooks to him, so that he didn't have to worry about having to hunt for textbooks (or buying it from the bookstore, with tax --damn GST), and I didn't have to worry about finding a buyer. (Also helped that I gave him advice from time to time about his courses, homework, etc.)
I can imagine that occasionally you'll find a textbook where you can't get 70% of original price, and I suppose that if the text changes to a new text (or new edition) that's required, you'd have trouble selling --but consistently below 70%? I find that surprising.

There's an excelent GPL program for Palm OS: Palm Fiction. It doesn't need any conversion programs, it can read plain .txt, .html, .rtf files, also in .zip or .gz compression, straight from the memory card. I used it on m500, Tungsten T3, TX and now on Treo 650 and I'm glad I've found it. The UI is so much configurable, I sometimes consider it a drawback.
;)
The only thing Palm Fiction lacks IMO is webpage and documentation in English
Of course it doesn't read any proprietary, encrypted formats, but since I've got Baen free and commercial offerings, as well as MLDonkey I can't complain. I just feel sorry for the publishers that don't want to take my money and thank the authors for their hard work in such cases.

What I don't understand is why more models don't support html. I mean, pdf, txt, and rtf are all fine. But it seems pretty clear that the best format for an ereader is one that will automatically adapt to the different sizes/resolutions of the device. Isn't html the best possible format for this?
Why don't all the ereaders support html?
None of the examples given in the article embody my ideal electronic ink application; none of these devices would come even close to getting me to give up paper books. I think Neal Stephenson had it right in his novel Diamond Age: an e-book should look and act just like a paper book—with some additional benefits, of course. The format could be anything between a small, thin, pocket-size paperback or something like an unabridged desk dictionary. There would be maybe a hundred pages or so in the ebook I'd carry around with me; they would look and feel pretty much like real paper, except that they'd be smudge and spill-resistant. And the ebook would be networked.
Your personal ebook could contain anything you want it to. You'd probably have a section devoted to email, another to newspaper articles—and both could be updated continually. There'd be a special "input" section—maybe inside one of the covers—that would allow you to write and send emails, make notes to yourself, or do any of a wide variety of computational tasks for which you'd use a laptop today. You could use a stylus, but a "keyboard" printed on the first page would be my choice for input. You'd need power for the networking and computational tasks, of course, but the text on the epages wouldn't disappear if your batteries went dead.
And of course, your ebook could contain books. Any book you want could be downloaded to a section of the ebook. You could read the book as you would a normal paper book, but the ebook pages would "refresh" as you read them. Say you download a novel. You'd get maybe the first 50 pages. By the time you got to the last page, the previous 49 would be replaced by pages 51-99 of the novel. Of course, if you wanted to have the whole novel at once, so you can riffle back and forth between the chapters, you'd have to buy the large format ebook--maybe one with 500 or even 1,000 pages. (That's not the way I'd go, though.)
I don't know how realistic my requirements are, but I do know that this is what it would take for me to abandon paper books. I have a feeling that I'll be reading paper for a long time to come.
Great men are almost always bad men--Lord Acton's Corollary
There's been many replies talking about the pros and cons of the current crop of reading devices, and although it hurt a little to put down $300 for the latest PRS-505, I have no regrets about it at all. Within a week I have read two complete books on it, and its been an absolute PLEASURE. I had tried reading ebooks on my Blackberry but the LCD emmisive screen hurt my eyes, and the constant scrolling was a pain. The Reader has been effortless to use and I've been FLYING through the text, and actually find myself MORE engaged with the book than a regular paper book. I don't have to move to turn the pages, so I remain comfortable at all times. The brief flash (NOT 2 or 3 seconds by any means) is hardly noticeable any longer, the multiple font sizes ease my tired eyes at the end of the day, and I'm loving the experience. I have an overseas trip coming up soon, and this will happily contain my reading material and not weigh my bag down. Carrying around large hardbacks is a pain, and this relieves me of it.
For me, this is a complement to plain old black and white paper books, which, for the most part, I read ONCE, from beginning to end and then shelve or give to charity or second-hand book shops. So for me, DRM is not an issue. The chances of me wanting to read the book again in 10 years time is so remote that I just don't care. I NEVER write in books, I never "look anything up" from a book, so I do not care about all these bells and whistles that some people seem to want. I never read paper books in the dark, so the lack of an attached light means nothing to me either.
For a regular READER, who reads books from beginning to end, then starts another book immediately, (meaning you're usually carrying two around), then this a GREAT device. The display is beautiful, and much better than last year's 500 model. I'm keeping track of how much money I've saved on paper books, and will probably break even sometime in 2009 by my calculations. But you know what, I don't even care if I never get to that point. It's been fun playing with my new gadget, I read way more than I listen to music, so in a toss up between an iPod or a Sony Reader, I'd pick the Reader everytime. Like the iPod, it does the job it was designed for, and does it well. Nuff said.
I was at Costco in Canoga Park, California (West Valley) and saw the new Sony 505 for $250, which includes a $50 certificate for electronic books. I didn't have time to find out more, but anyone considering buying an ebook reader might want to check this out.
Reading on the Sony Reader is faster with greater comprehension possible than for the same text with the same person on an ipod touch / pda screen
Even if the study were showing that, you may notice that the highest comprehension was achieved at the lowest reading speed, so the different conditions simply resulted in different speed/comprehension tradeoffs. By your reasoning, if you want to understand what you're reading, you should actually be using the slower device.
Of course, that presumes that the study itself is actually meaningful and relevant, but the experiments reported in that study are so incompetently done that you, in fact, can't infer anything from them.
