Devices To Take Textbooks Beyond Text

An anonymous reader writes with a New York Times piece about the tumultuous transition to electronic devices, instead of printed materials, for text. "Newspapers and novels are moving briskly from paper to pixels, but textbooks have yet to find the perfect electronic home. They are readable on laptops and smartphones, but the displays can be eye-taxing. Even dedicated e-readers with their crisp printlike displays can’t handle textbook staples like color illustrations or the videos and Web-linked supplements publishers increasingly supply. Now there is a new approach that may adapt well to textbook pages: two-screen e-book readers with a traditional e-paper display on one screen and a liquid-crystal display on the other to render graphics like science animations in color."

[ShooterNeo]

Yes, but the idea of a tablet is that it should be much lighter and smaller than a full computer. You'd be able to cart it around like a clipboard and use it in all sorts of industries. Ideally, the tablet would be about the size and weight of the screen on your laptop. It would be running a very low power usage CPU, and would have a power efficient display. Due to the slow CPU, it wouldn't be useful for a lot of things you can do with a laptop, but would be designed for working with lots of 2d documents.

Power it with an Nvidia Tegra processor [nvidia.com], and run Ubuntu Netbook Remix, and you've got one freaking awesome Internet tablet, with e-book reader being the killer app. Add a dynamically warping virtual multi-touch keyboard [billrocks.org], and you've got a killer device.

Re:

[mark-t]

An e-ink reader has less to do with being more compact than a netbook and more to do with being high contrast, and not requiring any power to sustain a static image, which is ideal for something like reading.

Re:

[Mprx]

E-ink displays have very bad contrast ratio. Typically about 10:1, compared to 1000:1 or more for an LCD. The only visual advantage of e-ink is higher DPI, which is a marketing based rather than technical benefit because there's no reason LCDs can't have just as high DPI (see the OLPC XO1's display, which is also reflective so it's usable in sunlight).

E-ink is a dead-end technology. Bistable LCDs will exceed it in ever aspect. Ferro Liquid Display technology looks promising.

Re:

[rockNme2349]

not requiring any power to sustain a static image

Bistable LCDs will exceed it in ever aspect

You can argue that LCDs will be more functional than e-ink displays, but there is no way that you can argue that there will be no niche that a no-power static display could fill better than an LCD.

Re:

[Mprx]

A bistable LCD is exactly that, but able to display motion too.

Re:

[mark-t]

The thing with e-ink displays though, is that _perceived_ contrast improves as ambient illumination gets increases, which is exactly the opposite with any display that emits its own light. When reading anything else, such as paper, contrast also improves as ambient illumination increases, so electronic displays that exhibit this characteristic feel easier on the eyes and are usually less tiring to look at for prolonged periods, as long as sufficient light exists to comfortably read them in the first place

Re:

Try reading a pc or netbook screen in direct sunlight. Able to do more doesn't mean diddly when you want contrast, which is what is really required for general reading.

Try reading E-ink in the dark. I don't think you can do that conveniently. Technology always has its draw backs I find it less likely that somebody's going to be studying outside in bright sun, than indoors where there's fewer distractions. Plus, there's any number of sun screens out there, they've been making them for years for graphics professionals.

Re:

Well, I don't normally read *books* in the dark either, so I don't give up anything by not being able to read an epaper display in the dark either. I can always use a lamp if I need to read something in a place where it's dark. Still, no display that emits light can produce decent contrast in sufficient ambient light.

Cause an E-Reader uses E-Ink, which only uses electricity when the text changes. It doesn't take any power to show static text, just change it. (unless, of course, you use the low power backlight)

But they will be willing to charge their textbook reader once per day (at night) especially if the reader (+ content): 1) costs less then the physical textbooks, 2) has school intranet access + internet access), 3) does a better job of explaining the subject material than the physical textbook and 4) organizes your notes into a study guide on the fly.

Re:

First of all, textbooks in an electronic format still cost a considerable amount. And any savings quickly evaporates once you factor in the cost of an e-reader. Yes most students do have laptops, however those have problems that have been explained elsewhere in this thread.

Also, who lugs their books to class? I certainly don't. Most of the time I just leave them at home.

This semester's accounting book was like that already for me.

After the next semester, I'll be stuck with a worthless pile of paper (not even as good as a worthless textbook.)

The e-reader will probably cost in the $500 range to cover cost. Each "book" will still cost $200 and will have to be bought again the next semester.

Reading comprehension fail?

It's getting better, I suppose

[RudeIota]

I think this is one of those ideas that *sound* better than it actually is. In short, adding graphics and video to electronic book readers are the first couple of steps into losing what a 'book reader' should be.

Many argue that eReaders "just aren't the same" as a real, 3 dimensional book. I agree... both literally and figuratively, I suppose. However, educational text books are perfect for eReaders. They are often enormous, have to be frequently carried around in conjunction with others book and I'm pretty sure most people don't care about how a text book 'feels'. So moving eReaders to book = good idea.

However, with an LCD screen, this changes things a bit. First, I feel this is losing the focus of what an 'eReader' is. It hasn't lost it yet -- but it is getting there. It blurs the line between an eReader and a Tablet... which could be a little blurry with a laptop already.

Another drawback over eReaders as we know them is we're going to see a pretty intensive increase in power usage. This is now going to be a device that needs to be charged hourly, depending on the battery size and how much multimedia they plan on packing into this thing. Books don't have videos and while it is neat, again, it is losing focus of being an electronic book and falling into the realm of tablet.

Take it a couple of more steps with web browsing, a keyboard etc... It's not longer an eReader. Personally, I'd rather have a 'dual screen' laptop that I could types notes on and read at the same time, since I'm going to spend a lot of my time looking in the general direction of an LCD already.

Problems with textbooks

[Darkness404]

The problem with textbooks are twofold, either A) You have to buy the textbooks themselves, and they are worthless after you stop taking that class (I mean, does anyone re-read old textbooks?) or B) Are given to you buy your education institution. Used electronic junk is usually pretty worthless and sometimes nasty (anyone want to get a pre-used keyboard?) and what is the use of a dedicated e-reader that will be used only for a semester?

Re:

Yes, I do reread old textbooks, or utilize them for reference quite a bit. The textbooks I don't intend to keep I sell back for about half of what I paid to the bookstore at the end of the semester so that they can be resold the following semester as a used book, as long as it is still in good condition, thus lowering the cost for future students.

Note : the e-paper screen on this device is 9.7" diagonal, which is the same size as the display on the kindle DX. Most likely it's the same part number.

This device is approaching the functionality of a truly useful electronic book. That's enough screen area to make an electronic textbook practical and close to being equivalent to the paper version. The true value of course is that you should be able to fit dozens or hundreds of books onto the machine. Plus : searchability, updates, electronic highlighting, etc.

Downside : publishers will try to destroy the used book market. They'll use DRM and various access controls to try to force every user to buy a separate copy.

Upside : open textbooks directly published by professors, available free or for under $15, will be more practical.

It would be a much more elegant solution to simply use one screen, which combines the abilities of both technologies. I think when e-ink displays are able to offer full-color and rapid-refresh rates as well as the current benefits of clarity and readability, they will replace LCDs altogether.

Who needs colour textbooks

[ittanmomen]

Its a silly argument that the article makes. E-Readers can display B&W pages, and gray shades. This is absolutely sufficient for displaying textbooks. There is a line of extremely bloated textbooks that takes liberties with layout and colour. I just wonder for what purpose colour is used in those books. In my opinion it does neither help understanding of diagrams and models, nor does it improve the information density. Perhaps a revisit of Tufte's rules for information design is in order for publi

Not if the the book has a chapter on spectroscopy or titration (is the reaction pink or purple?), or shows maps (which shade of grey is water vs land?) or flags of the world. That's just 3 things found in textbooks I can think of that would not work well in grey-scale.

Pretty damn sure you are making an unfair comparison here. Unless textbooks in the author gets all his textbooks from Hogwarts.

dedicated e-readers with their crisp printlike displays

Bullshit. There ARE no such e-readers, unless the only print you've ever seen is darkish grey text on lightish grey paper. E-reader displays are NOWHERE NEAR 'printlike' yet. Ugh.

There are LCD screen book readers that are better than most non-artsy printed books, where the battery life is merely a week or so. Certainly higher contrast than an old yellowed paperback.

Then there are e-Ink or e-Paper or whatever screen book readers, that have no redeeming characteristic at all, other than a battery life measured in page turns, which for a slow reader is possibly measured in months.

The problem is the assumption that given that its technologically hard to make a high contrast display, th

Our school system must change to reflect this.

[RicktheBrick]

There is no excuse for not totally changing our school system. First we should eliminate the grade system. People should have the option of trying to learn a subject until they give up. If someone is trying to learn something than the school system should not shut them off. Second is that we should redefine what teachers do for a living. Computer should be used to teach our children. Teachers should be called motivators. They would have a one on one discussion with each student every day. They would

Could have just given a link to wikipedia

Assuming you're not just making this all up, I would guess you really enjoyed "the little schemer" LISP/Scheme textbook series?

I'm related by marriage to two school teachers. This is a great plan for teaching math, like you mentioned, such as trigonometric identities. Not so good for creative writing. The other problem is, according to my relatives, and most things I've read online, "teachers" only really "teach"

Re:

[Brianwa]

I had a math teacher try something like this for a single chapter. The instruction was still textbook and lecture based, but there were daily assignments that were computer generated and would not let you move on until you had "mastered" the prescribed skillsets. Every assignment corresponded to specific pages of the textbook, so it was basically like what you described. I finished weeks late and very nearly failed that chapter. It was absolutely terrible and if entire classes had been designed like tha

You obviously don't know much about learning and teaching. Having a student reread pages until they pass the test is a waste of time. If you don't understand the material after reading (maybe twice), you need a different explanation of the material; something that any competent teacher will recognize.

The data format is more important than the device.

[lamapper]

There is something about a newspaper, magazine, book, flipping through it that I simply love. I find it relaxing and enjoyable to lazily leaf through a book, magazine or newspaper. Always will.

I have to admit that if I were searching for a phrase or phrases I would prefer to have it on a computer. Just works better.

What matters to me more is not the device (hand held, net book, tablet, laptop, PC, desktop, tower, etc...) but the data format.

I want to purchase my content ONCE, maybe twice if I have too, but not repeatedly for the rest of my life, every three or four years. That it crazy. I was taught at a young age to try to avoid being penny-wise and dollar foolish. I like to purchase things that last. So if you put the content on cheap materials that will not last, your bad, you will lose my business. I would rather save more money, pay a little more and get the data on better materials that will last. Look at furniture, I will not buy cheap furniture that breaks in less than a year. I would rather pay more (its usually not that much more either) and have it last, it should still be in good shape so that I can give it to my grandchildren if I want too. Instead of something cheaply made that will not last till I see my own children. What a waste of money.

To buy too cheap is penny wise and dollar foolish.

I apply the same logic to computer hardware and software that is proprietary in nature. Having been burned not just once, not just twice, but many more times than three, I am simply tired of seeing my hard earned money being drained away by insane fees, charges and forced updates. I will pay for innovation, however I am hard pressed to see how spreadsheets, word-processors and database programs have really improved enough to be labeled "innovative" since Windows 95/98. Granted you might have a chance with databases of finding one or two obscure new features that might be a "must have". But not with Spreadsheets and Word-Processors.

A friend of mine loved WordPerfect, the technical writers would keep finding new ways to apply WordPerfect to their craft, technical writing, literally every day, day in, day out for multiple years. It was not because the product had been improved, though it was, it was because the product was feature rich and would let a master at their craft (word processing, tech writing, etc..) really excel. Word Perfect was the best Word Processor ever. That was years before Word gained only because of Microsoft Office and Microsoft's control of the desktop. Even later when most had switched to Word after Microsoft corrupted their own file formats to force users to upgrade to the new Word, the experts, the technical writers who knew their craft preferred WordPerfect and other Desktop Publishing tools. It just made sense.

Word did not take over through innovation, but it did take over none the less. We are all poorer for the lack of innovation.

So the idea of forcing us to buy some proprietary e-reader hardware in order to read a proprietary data format that could just as easily be provided in an open data format is crazy. Quite frankly it is beyond offensive and hardly endears us to your brand.

We were not born yesterday.

Even those (probably because they are simply too inexperienced) that have not experienced this kind of FUD, still understand the concept.

Buy me (book, music, content, etc...) on this device in that format (proprietary of course) and in a couple of years that device (proprietary) will be left without support (because we said so) and not only will you be forced to purchase the content again because of the proprietary data format; but they (proprietary company) will attempt to force me (and you dear reader if you mistakenly bought in the last time) to purchase yet more new hardware (proprietary of course) that offers yet again, no new innovative features.

Those things don't even waste power when displaying a page, only when you change it. It's like an "Etch A Sketch" of sorts: no backlight, no refreshing; you need ambient light the same way you need it for real books. Supports all common formats, ARM9 running Linux. No DRM, no wifi connecting on your back to delete your stuff, simple usb mass storage transfer: connect, copy and go, no software nonsense, and it has an SD slot...

Was interested so did a little searching. The Linux OS is Wolf Linux, not real familiar with it, though I am sure others may be. Before you can develop with Wolf Linux here is what the company said, "We will provide the SDK of all of our products based on Linux OS, not only provide it to OEM and ODM, but also to personal cooperators. But the cooperators need to sign a cooperation agreement with us, which will relate to the management of version and DRM." [mobileread.com]

[pydev]

Having two different display technologies in the same device is hell in terms of UI design and development. Those hassles mean that you're probably better off just using two LCDs instead of trying to combine e-ink and LCD technology into one gadget.

Well by the time this is implemented at all, I will be done with my schooling and get little use out of it. If I ever have children, hopefully by then this will be commonplace.

How about a two-screen laptop with a traditional LCD display on one screen and a textbook display on the other to render crisp printlike graphics?
