How e-books work: a guide to electronic books and e-book readers: Explain that Stuff! - 0 views

  • Back in the 19th century English author, Martin Tupper wrote: "A good book is the best of friends, the same today and for ever." It's true: books are friendly, familiar, and loveable and that probably explains why it's taking us so long to get used to the idea of portable electronic books. But with the arrival of a new generation of electronic book readers, such as the Sony Reader, and Amazon Kindle, the days of the printed word just might be numbered. Let's take a closer look at electronic books (e-books) and find out how they work! Photo: Left: Amazon Kindle electronic book reader.

Right: The rival Sony Reader PRS-350 is considerably smaller, partly because its touch-sensitive screen does away with the need for a keyboard.
  • contain Think of a book and you think of a single object, but the books we read are actually two things in one: there's the information (the words and pictures and their meaning) and there's the physical object (the paper, cardboard, and ink) that contains them. Sometimes the physical part of a book is as important as the information it carries: it's really true that we judge books by their covers—at least when we're standing in shops deciding which ones to buy—and that's why publishers devote so much attention to making their books look attractive. But, a lot of the time, the information is much more important to us and we don't really care how it's delivered. That's why many of us now turn to the Web when we want to find things out instead of visiting the local library. In short, we've learned to split off the information we need from the way it's delivered. E-books take this idea a step further. When we talk about an e-book, we really mean a digital version of a printed text that we can read on a handheld electronic device like a miniature laptop computer— two quite separate things, once again.
  • How do you store a book in electronic form? An e-book is really just a computer file full of words (and sometimes images). In theory, you could make an e-book just by typing information into a word processor. The file you save has all the elements of an electronic book: you can read the information on a computer, search it for keywords, or share it easily with someone else. The first attempt to create a worldwide library of e-books was called Project Gutenberg and it's still running today. Long before the World Wide Web came along, a bunch of dedicated Gutenberg volunteers took printed books and scanned or typed them into their computers to make electronic files they could share. For legal reasons, these books were (and still are) mostly classic old volumes that had fallen out of copyright. The electronic versions of these printed books are very basic, text-only computer files stored in a format called ASCII (American Standard Code for Information Interchange)—a way of representing letters, numbers, and symbols with the numbers 0-255 that virtually every computer can understand. Photo: The Amazon Kindle electronic book reader (left) alongside a rival, the Sony eReader (right). Photo by courtesy of John Blyberg, published on Flickr under a Creative Commons License. Note the picture displayed on the Kindle screen: E Ink screens can show pictures, though so far only in very unimpressive black and white. The problem with ASCII is that the text contains very little formatting information: you can't distinguish headings from text, there's only one basic font, and there's no bold or italics. That's why people developed much more sophisticated electronic files like PDF (Portable Document Format). The basic idea of PDF was to store an almost exact replica of a printed document in an electronic file that people could easily read on screens or print out, if they preferred. The HTML files people use to create web pages are another kind of electronic information. Every HTML page on a website is a bit like a separate page in a book, but the links on web pages mean you can easily hop around until you find exactly the information you want. The links on websites give you powerfully interconnected information that is often much quicker to use than a library of printed books. The greatest strength of ASCII, PDF, and HTML files (you can read them on any computer) is also their greatest weakness: who wants to sit staring at a computer screen, reading thousands of words? Most screens are much less sharp than the type in a printed book and it quickly tires your eyes reading in this way. Even if you can store lots of books on your computer, you can't really take it to bed with you or read it on the beach or in the bath-tub! Now, there's nothing to stop you downloading simple text files onto something like an iPod or a cellphone and reading them, very slowly and painfully, from the small LCD display—but it's not most people's idea of curling up with a good book. What we really need is something with the power of a computer, the portability of a cellphone, and the friendliness and readability of a printed book. And that's exactly where electronic book readers come in.

  • How do you read an electronic book file? An electronic book reader is a small, portable computer designed for reading books stored in a digital format such as ASCII, PDF, HTML, or another similar format. (Currently the two most popular ebook formats are EPUB, a worldwide, open standard that evolved from an earlier standard called OEB (Open e-book) and widely used by Sony Readers and most other ebook readers, and AZW, a proprietary format developed by Amazon and currently readable only on its Kindle reader.) Books take up very little space when you store them in electronic format: you could easily fit 10,000 electronic copies of the Bible onto a single DVD. Most ebook readers can store hundreds or even thousands of titles at a time and some have Wi-Fi Internet connections so you can download more books whenever you wish. The most important part of an e-book reader is the screen. The first e-books used small versions of LCD laptop screens which have a resolution (sharpness) of about 35 pixels per cm (90 pixels per inch). You could easily see the dots making up the letters and it was quite tiring to read for more than a few minutes at a time. The latest e-books use an entirely different technology called E Ink. Instead of using LCD displays, they show words and letters using tiny, black and white, plastic granules that move about inside microscopic, spherical capsules under precise electronic control. Displays like this have about twice the resolution of ordinary computer screens, are clearly visible in sunlight, and use much less power. In fact, they're almost as sharp and easy to read as printed paper. The lack of books in electronic format is one of the things that puts people off using e-book readers—and that's what makes Amazon.com's new Kindle reader such an exciting development. Amazon already works with virtually all the world's publishers as a bookseller, so it's been able to make huge numbers of titles available for Kindle in electronic format—over 88,000 books were available on the launch date. That's certainly what people want and expect from an e-boo
  • All these products are broadly similar: they're all light, portable, and handheld and they all have large internal flash memories that hold hundreds of books. Some have touchscreens; others (like the Kindles) have miniature keyboards. Some have wireless connections for downloading more books; others (such as the Sony Readers) have to be connected to a computer with a USB cable. If you connect with a cable, running an ebook reader is rather like running an iPod or MP3 player: typically you maintain a library on your PC with a piece of software similar to iTunes, to which you add and remove books and other documents. When you plug in your reader, it synchronizes its internal memory with the library on your PC, adding any new books and deleting any unwanted ones. If you have a wireless reader, you maintain your library on the reader itself, adding and removing books directly. So... wireless or cable? It's not a big issue, I don't think: you'll probably be downloading books relatively infrequently. Photo: Horses for courses: The Sony Reader has a much smaller page size than a typical hardbook book. That's great if you want to carry your reader in your jacket pocket or your handbag so you can read while you're travelling. It's much less attractive if you do most of your reading at home: the smaller the screen, the more often you'll need to turn the pages. This is one example of why it pays to think about how you're going to use an ebook reader before you buy it. The best and most expensive readers use extremely high-resolution E Ink screens that work better in daylight than at night (you'll need good indoor lighting or a clip-on light if you're planning to do most of your e-reading in the evenings); LCD-screen readers (such as the Elonex) have backlit screens that favor indoor use and (like computer screens) can be tricky to read in bright sunlight. E Ink apparently uses energy only when you turn the pages, so the Sony Reader can happily survive for about two weeks of very heavy use on a single charge of the batteries. That means it's also very environmentally friendly to read books or documents from a handheld ebook reader compared to reading them on a computer screen. Some ebook readers can cope with ebooks in all kinds of different formats. The Sony Reader, for example, lets you read Microsoft Word and PDF files, as well as standard formats such as EPUB. The PDF viewer is really neat, allowing you to rotate the screen or scroll documents column-by-column for easy reading. The Amazon Kindle doesn't currently support the EPUB format, but it does allow you to view other file formats such as PDF.
  • Where can you get ebooks from? Most books currently produced by publishers are copyrighted, which means you can expect to pay a fair price if you want to use them. Relatively few publishers have embraced ebooks so far, though there are some notable exceptions (including Penguin). Generally, it's relatively easy to find mass-market bestsellers in ebook format but much harder to find more specialized books and quality, literary fiction. Public domain classics are the easiest books to find in ebook format, largely thanks to the sterling and visionary work of Project Gutenberg. If you enjoy reading classic novels, buying an ebook reader is probably a no-brainer; if you're more a fan of 20th century literary fiction, you'll have a much harder time finding what you want in digital form. If you buy copyright ebooks from either Amazon or another outlet, you'll find they're protected by what's called DRM (digital rights management)—effectively a kind of encryption that prevents people from distributing pirate copies of books illegally. Amazon uses its own DRM system, while Sony (and others) use a system developed by Adobe called Adobe Digital Editions, which requires you to register your reader the first time you use it. DRM protection restricts what you can do with books you've bought, but it's not necessarily the drawback it seems. First, it's very much a necessity from a publisher's point of view: it's only because ebook readers like the Kindle have DRM protection built in that publishers are starting to take what they see as a major risk in making their books available in digital formats. Another advantage of DRM is that it allows libraries to lend people ebooks for limited periods of time. I'm delighted to find I can log in to my local library and download, for free, for periods of up to 14 days, a reasonable selection of a few hundred popular ebooks. Once the borrowing time has expired, the books delete themselves automatically from my reader!

Augmented reality - Wikipedia, the free encyclopedia - 0 views

  • Augmented reality (AR) is a term for a live direct or an indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input, such as sound or graphics.
  • Augmented reality (AR) is a term for a live direct or an indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input, such as sound or graphics. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality. By contrast, virtual reality replaces the real-world with a simulated one.
  • AR has become common in sports telecasting. The yellow "first down" line seen in television broadcasts of American football games shows the line the offensive team must cross to receive a first down using the 1st & Ten system. The real-world elements are the football field and players, and the virtual element is the yellow line, which augment the image in real time. Similarly, in ice hockey an AR colored trail shows location and direction of the puck. Sections of Rugby fields and cricket pitches display sponsored images.

For example, at the 2008 LA Auto Show, Nissan unveiled the concept vehicle Cube and presented visitors with a brochure which, when held against a webcam, showed alternate versions of the vehicle.[21] In August 2009, Best Buy ran a circular with an augmented reality code that allowed users with a webcam to interact with the product in 3D.[22] In 2010 Walt Disney used mobile AR to connect a movie experience to outdoor advertising.[23]

Gesture-Based Computing Uses $1 Lycra Gloves | Gadget Lab | Wired.com - 0 views

  • Interacting with your computer by waving your hands may require just a pair of multicolored gloves and a webcam, say two researchers at MIT who have made a breakthrough in gesture-based computing that’s inexpensive and easy to use. A pair of lycra gloves — with 20 irregularly shaped patches in 10 different colors — held in front of a webcam can generate a unique pattern with every wave of the hand or flex of the finger. That can be matched against a database of gestures and translated into commands for the computer. The gloves can cost just about a dollar to manufacture, say the researchers. “This gets the 3-D configuration of your hand and your fingers,” says Robert Wang, a graduate student in the computer science and artificial intelligence lab at MIT. “We get how your fingers are flexing.” Wang developed the system with Jovan Popović, an associate professor of electrical engineering and computer science at MIT. The technology could be used in videogames where gamers could pick up and move objects using hand gestures and by engineers and artists to manipulate 3-D models.

Coffee Table Computing - A look at collaborative design - 0 views

  • Let me start by declaring that we, as human beings DO NOT have the ability to communicate with computers. Ever since the modern user interface based the WIMP system of Xerox Corp. came about people have found ways to use applications design around tasks and features. There are programmers and there are users. Computers work digitally, and humans cannot easily translate information to store and instruct computers. This has been a limitation and will be, for a long time. Several companies have tried to get out of this cycle by introducing newer touch and gesture based user interface which hold little value beyond novelty. These have been shown in several movies (including Iron Man 2 – where Tony Shark check’s out pictures of the Black Widow online on his table-top display) However, I’m glad that companies are taking this seriously after the touch interface of the iPhone sparked of a UI craze that has picked up quite a pace. One experimental entrant is the MS Surface. This is a table size computer with the screen facing up and is multi-touch capable. Several great instances of object recognition and collaboration of devices and people have been demonstrated on this device, but it hasn’t been taken seriously as yet (which is probably a cost factor for now)

E-book - Wikipedia, the free encyclopedia - 0 views

shared by brooke s on 17 Mar 11 - Cached
  • An electronic book (also e-book, ebook, digital book) is a text and image-based publication in digital form produced on, published by, and readable on computers or other digital devices.[1] Sometimes the equivalent of a conventional printed book, e-books can also be born digital. The Oxford Dictionary of English defines the e-book as "an electronic version of a printed book,"[2] but e-books can and do exist without any printed equivalent. E-books are usually read on dedicated hardware devices known as e-Readers or e-book devices. Personal computers and some cell phones can also be used to read e-books.
  • availability of e-books may be provided for users with a mobile data connection, so that these e-books need not be stored on the device. An e-book can be offered indefinitely, without ever going "out of print". In the space that a comparably sized print book takes up, an e-reader can potentially contain thousands of e-books, limited only by its memory capacity.
  • Among the earliest general e-books were those in Project Gutenberg, in 1971. One early e-book implementation was the desktop prototype for a proposed notebook computer, the Dynabook, in the 1970s at PARC: a general-purpose portable personal computer capable of displaying books for reading.[3] Early e-books were generally written for specialty areas and a limited audience, meant to be read only by small and devoted interest groups. The scope of the subject matter of these e-books included technical manuals for hardware, manufacturing techniques and other subjects.[citation needed] In the 1990s, the general availability of the Internet made transferring electronic files much easier, including e-books. Numerous e-book formats, view comparison of e-book formats, emerged and proliferated, some supported by major software companies such as Adobe with its PDF format, and others supported by independent and open-source programmers. Multiple readers followed multiple formats, most of them specializing in only one format, and thereby fragmenting the e-book market even more. Due to exclusiveness and limited readerships of e-books, the fractured market of independents and specialty authors lacked consensus regarding a standard for packaging and selling e-books. In 2010 e-books continued to gain in their own underground markets. Many e-book publishers began distributing books that were in the public domain. At the same time, authors with books that were not accepted by publishers offered their works online so they could be seen by others. Unofficial (and occasionally unauthorized) catalogs of books became available over the web, and sites devoted to e-books began disseminating information about e-books to the public. [4] U.S. Libraries began providing free e-books to the public in 1998 through their web sites and associated services,[5] although the e-books were primarily scholarly, technical or professional in nature, and could not be downloaded. In 2003, libraries began offering free downloadable popular fiction and non-fiction e-books to the public, launching an e-book lending model that worked much more successfully for public libraries.[6] The number of library e-book distributors and lending models continued to increase over the next few years. In 2010, a Public Library Funding and Technology Access Study[7] found that 66% of public libraries in the U.S. were offering e-books,[8] and a large movement in the library industry began seriously examining the issues related to lending e-books, acknowledging a tipping point of broad e-book usage.[9] As of 2009[update], new marketing models for e-books were being developed and dedicated reading hardware was produced. E-books (as opposed to ebook readers) have yet to achieve global distribution. In the United States, as of September 2009, the Amazon Kindle model and Sony's PRS-500 were the dominant e-reading devices.[10] By March 2010, some reported that the Barnes & Noble Nook may be selling more units than the Kindle.[11] On January 27, 2010 Apple Inc. launched a multi-function device called the iPad[12] and announced agreements with five of the six largest publishers that would allow Apple to distribute e-books.[13] However, many publishers and authors have not endorsed the concept of electronic publishing, citing issues with demand, piracy and proprietary devices.[14] In July 2010, online bookseller Amazon.com reported sales of ebooks for its proprietary Kindle outnumbered sales of hardcover books for the first time ever during the second quarter of 2010, saying it sold 140 e-books for every 100 hardcover books, including hardcovers for which there was no digital edition.[15] By January 2011, ebook sales at Amazon had surpassed its paperback sales.[16] In the overall U.S. market, paperback book sales are still much larger than either hardcover or e-book; the American Publishing Association estimated e-books represented 8.5% of sales as of mid-2010.[17] In Canada, the option of ebook publishing took a higher profile when the novel, The Sentamentalists, won the prestigious national Giller Prize. Owing to the small scale of the novel's independent publisher, the book was initially not widely available in printed form, but the ebook edition had no such problems with it becoming the top-selling title for Kobo devices.[18]

  • Drawbacks Ebook formats and file types continue to develop and change through time through advances and developments in technology or the introduction of new proprietary formats. While printed books remain readable for many years, e-books may need to be copied or converted to a new carrier or file type over time. PDF and epub are growing standards, but are not universal. The lack of a single universal standard could significantly affect the longevity of some works and their availability or readability in the future as a result of the format(s) used at the time of production.[26] Not all books are available as e-books. Paper books can be bought and wrapped for a present and a library of books can provide visual appeal, while the digital nature of e-books makes them non-visible or tangible. E-books cannot provide the physical feel of the cover, paper, and binding of the original printed work. An author who publishes a book often puts more into the work than simply the words on the pages. E-books may cause people "to do the grazing and quick reading that screens enable, rather than be by themselves with the author's ideas".[27] They may use the e-books simply for reference purposes rather than reading for pleasure and leisure.[28] Books with large pictures (such as children's books) or diagrams are more inconvenient for viewing and reading. A book will never turn off and would be unusable only if damaged or after many decades. The shelf life of a printed book exceeds that of an e-book reader, as over time the reader's battery will drain and require recharging. Additionally, "As in the case of microfilm, there is no guarantee that [electronic] copies will last. Bits become degraded over time. Documents may get lost in cyberspace...Hardware and software become extinct at a distressing rate." [29] E-book readers are more susceptible to damage from being dropped or hit than a print book. Due to faults in hardware or software, e-book readers may malfunction and data loss can occur. As with any piece of technology, the reader must be protected from the elements (such as extreme cold, heat, water, etc.), while print books are not susceptible to damage from electromagnetic pulses, surges, impacts, or extreme temperatures. The cost of an e-book reader far exceeds that of a single book, and e-books often cost the same as their print versions. Due to the high cost of the initial investment in some form of e-reader, e-books are cost prohibitive to much of the world's population. Furthermore, there is no used e-book market, so consumers will neither be able to recoup some of their costs by selling an unwanted title they have finished, nor will they be able to buy used copies at significant discounts, as they can now easily do with printed books. Because of the high-tech appeal of the e-reader, they are a greater target for theft than an individual print book. Along with the theft of the physical device, any e-books it contains also become stolen. E-books purchased from vendors like Amazon or Barnes & Noble.com are stored "in the cloud" on servers and "digital lockers" and have the benefit of being easily retrieved if an e-reading device is lost. Not all e-booksellers are cloud based; if an e-book is stolen, accidentally lost, or deleted, in the absence of a backup it may have to be repurchased. The screen resolutions of reading devices are currently lower than actual printed materials.[30] Because of proprietary formats or lack of file support, formatted e-books may be unusable on certain readers. Additionally, the reader's interaction with the reader may cause discomfort, for example glare on the screen or difficulty holding the device. Due to digital rights management, customers typically cannot resell or loan their e-books to other readers.[31] However, some Barnes & Noble e-books are lendable for two weeks via their 'LendMe' technology.[32] Additionally, the potential for piracy of e-books may make publishers and authors reluctant to distribute digitally.[33] E-book readers require various toxic substances to produce, are non-biodegradable, and the disposal of their batteries in particular raises environmental concerns. As technologies rapidly change and old devices become obsolete, there will be larger amounts of toxic wastes that are not easily biodegradable like paper. E-books and software can easily track data, times, usage, pages, and details about what one is reading and how often. Similar to this is the growing amount of data available through Google search engines, Facebook, and through data mining. For the first time in history it is now far easier to track and record what specific people might be reading. The notions of privacy, private writing, solitude, and personal reading are changing.
  • Digital rights management Anti-circumvention techniques may be used to restrict what the user may do with an e-book. For instance, it may not be possible to transfer ownership of an e-book to another person, though such a transaction is common with physical books. Some devices can phone home to track readers and reading habits, restrict printing, or arbitrarily modify reading material. This includes restricting the copying and distribution of works in the public domain through the use of "click-wrap" licensing, effectively limiting the rights of the public to distribute, sell or use texts in the public domain freely. Most e-book publishers do not warn their customers about the possible implications of the digital rights management tied to their products. Generally they claim that digital rights management is meant to prevent copying of the e-book. However in many cases it is also possible that digital rights management will result in the complete denial of access by the purchaser to the e-book.[34] With some formats of DRM, the e-book is tied to a specific computer or device. In these cases the DRM will usually let the purchaser move the book a limited number of times after which he cannot use it on any additional devices. If the purchaser upgrades or replaces their devices eventually they may lose access to their purchase. Some forms of digital rights management depend on the existence of online services to authenticate the purchasers. When the company that provides the service goes out of business or decides to stop providing the service, the purchaser will no longer be able to access the e-book. As with digital rights management in other media, e-books are more like rental or leasing than purchase. The restricted book comes with a number of restrictions, and eventually access to the purchase can be removed by a number of different parties involved. These include the publisher of the book, the provider of the DRM scheme, and the publisher of the reader software. These are all things that are significantly different from the realm of experiences anyone has had with a physical copy of the book.
  • Production Some e-books are produced simultaneously with the production of a printed format, as described in electronic publishing, though in many instances they may not be put on sale until later. Often, e-books are produced from pre-existing hard-copy books, generally by document scanning, sometimes with the use of robotic book scanners, having the technology to quickly scan books without damaging the original print edition. Scanning a book produces a set of image files, which may additionally be converted into text format by an OCR program.[35] Occasionally, as in some e-text projects, a book may be produced by re-entering the text from a keyboard. As a newer development, sometimes only the electronic version of a book is produced by the publisher. It is even possible to release an e-book chapter by chapter as each chapter is written. This is useful in fields such as information technology where topics can change quickly in the months that it takes to write a typical book (See: Realtime Publishers). It is also possible to convert an electronic book to a printed book by print on demand. However these are exceptions as tradition dictates that a book be launched in the print format and later if the author wishes an electronic version is produced. As of 2010, there is no industry-wide e-book bestseller list, but various e-book vendors compile bestseller lists, such as those by Amazon Kindle Bestsellers[36] and Fictionwise.[37] There are two yearly awards for excellence in e-books—the EPIC eBook Award[38] (formerly EPPIE) given by EPIC, and the Dream Realm Award[39] for science fiction, fantasy and horror e-books. Both awards have been given since 2000.
  • e-Readers For more details on e-book readers, see Comparison of e-book readers. e-Readers may be specifically designed for that purpose, or intended for other purposes as well. The term is restricted to hardware devices and used to describe a category type. Specialized devices have the advantage of doing one thing well. Specifically, they tend to have the right screen size, battery lifespan, lighting and weight. A disadvantage of such devices is that they are often expensive when compared to multi-purpose devices such as laptops and PDAs. In 2010, competition sent the price for the most popular electronic reading devices below USD 200.[40] Research released in March 2011 indicated that e-books and e-book readers are actually more popular with the older generation than the younger generation in the UK. The survey carried out by Silver Poll found that around 6% of over 55s owned an e-book reader compared with just 5% of 18-24 year olds. [41] The survey also revealed that the Amazon Kindle is the most popular e-book reader in the UK (47%) followed by the Apple iPad (31%) and the Sony Reader (14%). It has been reported that there is a differing level of dissatisfaction amongst owners of different ebook readers due to poor availability of sought after ebook titles. A survey of the number of contemporary and popular titles available from ebook store, revealed that Amazon.com has the largest collection, over twice as large as Barnes and Noble, Sony Reader Store, Apple iBookstore and OverDrive, the public libraries lending system.

About eBooks - 0 views

  • As noted elsewhere, the Poitin Press is a virtual publishing house in that it sells its books over the Internet both as printed and eBooks. Our reasons for us doing so are explained in "About Us". In this section we would like to briefly explain the current state of eBooks, what your options are, and what are the advantages and disadvantages of each. The intent is to help you make your choice of which is for you.
  • Presently, there are several different formats of eBooks.  They fall into two basic categories: Those that run on a computer such as a workstation or laptop, and those that require a special device, often called an "eBook" but are really a special-purpose computer in their own right.  A third category based on PDAs and similar hand-held devices is also available. 
  • One interesting factoid is that while the popularity of workstations is dropping, they are not being replaced by "Internet appliances" as touted in the last few years, or even PDAs, or the new "Tablets." By far and away, the choice is still the combination of laptops and PDAs, which are generally used in combination by today's cyber road-warriors. The PDA is used during meetings and such and then downloaded into the laptop so that the information can be gathered into spreadsheets, reports, and presentations.  This makes the laptop the hardware of choice for the eBook marketers because the target customer is likely to already have one, and so does not have to buy, support and cart around yet another bit of hardware. For this reason, we have chosen to support only those eBook formats that can run on a laptop. There are three such formats: Palm eBook, Microsoft's Reader, and Adobe's Acrobat eBook Reader.  They are not compatible with each other. They have fundamentally different technology in each and one cannot display the other's format.

  • Overview of How eBooks Work. Basically, all eBooks work the same. You go to an Internet-based bookseller, order a book, download it into your "reader" whatever it might be, and enjoy reading.  The issue is keeping people from then emailing hundreds if not thousands of copies to everybody else. Thus the concept of  Digital Rights Management (DRM) comes to the forefront. The way DRM is accomplished is for the bookseller to download the eBook  to a registered reader only. The procedure is basically as follows in the case of laptop-based readers. You go to the website of the maker of the reader (see examples on How to Order), and download the reader software into your laptop or workstation.   You register the reader. There are various ways of doing this, but the key in all of them is that they take some unique information about your computer and send it back to the registration site. In the case of both Acrobat eBook Reader and Microsoft Reader, they use the volume header ID of your system disk as well as other information such as CPU model. This means that you cannot reformat your system drive should you have a disk problem, let alone replace it, without having problems with your eBooks.    You go to the bookseller's site, order your book, and when it is ready for download, you must download it to the laptop or workstation that has the registered reader in it. The downloaded eBook is then stamped with a code that is used by the reader to decide if you have a legitimate copy of the book or not.  There are many detailed variations in the above between the Adobe Acrobat Reader and the Microsoft Reader. We urge you to go to their respective websites and read about them. Generally, as far as DRM is concerned, both Microsoft and Adobe do a thorough job of preventing the improper copying of eBooks.   The Palm DRM depends on just how much you trust those you give the eBook to -- an interesting DRM concept (see below).

SixthSense - a wearable gestural interface (MIT Media Lab) - 0 views

  •  
    The SixthSense prototype is comprised of a pocket projector, a mirror and a camera. The hardware components are coupled in a pendant like mobile wearable device. Both the projector and the camera are connected to the mobile computing device in the user's pocket. The projector projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces; while the camera recognizes and tracks user's hand gestures and physical objects using computer-vision based techniques.

Augmented Reality - 0 views

  • The basic idea is to immerse a user inside an imaginary, computer-generated "virtual world." Although many different technologies can be used to achieve this effect, they all share a common result: the user is cut off from any view of the real world outside. Much less attention has been paid to the field of Augmented Reality, although its potential is at least as great as that of Virtual Environments. In Augmented Reality, the user can see the real world around him, with computer graphics superimposed or composited with the real world. Instead of replacing the real world, we supplement it. Ideally, it would seem to the user that the real and virtual objects coexisted.

  • Augmented reality is changing the way we view the world -- or at least the way its users see the world. Picture yourself walking or driving down the street. With augmented-reality displays, which will eventually look much like a normal pair of glasses, informative graphics will appear in your field of view, and audio will coincide with whatever you see. These enhancements will be refreshed continually to reflect the movements of your head. Similar devices and applications already exist, particularly on smartphones like the iPhone.
  • Now, researchers and engineers are pulling graphics out of your television screen or computer display and integrating them into real-world environments. This new technology, called augmented reality, blurs the line between what's real and what's computer-generated by enhancing what we see, hear, feel and smell.

Augmented Reality in Education - WikEd - 0 views

  • he 2010 Horizon Report includes examples of augmented reality like the Wii under the category Gesture Based Computing. Gesture recognition enables humans to interact with mechanical devices using simple natural gestures. In the future, the use of a keyboard, a mouse or even a touch pad may become a thing of the past with innovations in gesture based computing. See a video slide show of The New Media Consortium/ Educause report Click Gesture-Based Computing : 2010 NMC Horizon Report iPhone geotags. Geotagging and Geolocation Another important part of augmented reality applications is the use of geotagging and geolocation. A Geotag is a GPS coordinate that associates content such as videos, textual information, audio or any user- generated content to a specific location. When photographers use digital cameras, they have the choice to date stamp the video or photo. A Geotag is similar to that type of tag. AR applications draw on specific tags created by companies but will also depend on content that everyday users add through Geotagging. When we go to Google Earth to view a location, we are now able to find pictures and information added by users through these types of tags. Marker vs Markerless Augmented Reality AR Marker QR Code. AR Marker QR Semacode. Currently, many people associate augmented reality with black and white squares that trigger augmented reality elements. These black and white squares are called markers. Markers are also called QR (Quick Response) codes or Semacodes. A QR code is a two dimentional bar code that allows its content to be decoded at high speed. Markerless technology requires no marker to know the position of the object or person. Smartphone browsers that layer information over live locations are often considered in the markerless category, although they still use embedded "marked" information through geolocation and geotagging. The goal is to have augmented reality work much like this HP commercial Jerry Seinfeld for HP

Never has augmented reality been so fast and easy. A wearable display with a 67-inch screen, as viewed from ten feet, stereo video capture, 6-degrees of freedom head tracking, VGA connectivity for your computer and plug-in software to bring your Autodesk® 3ds Max® characters to life – this bundle has it all.
  • Augmented reality or AR is a mixture of the real-world and virtual computer-generated imagery or information. With the Wrap 920AR, the real world is captured by it’s stereo camera system and displayed in the eyewear on what appears to your eyes as a 67-inch display as seen from 10-feet (3m). This image, which can be displayed in standard 2D or 3D, can be augmented with virtually any form of computer-generated data in the form of text, still images or even video. Until now, augmented reality has been limited to bulky stationary displays or portable hand-held systems with limited capabilities. Although these solutions implemented AR technology, it was in an unnatural format with obvious technology barriers. The Wrap 920AR is the first consumer product that empowers users to experience AR in a real-world environment – worn like sunglasses and displaying 3D graphics. Developer Support Vuzix provides an evolving SDK (Software Development Kit) and additional resources designed to aid and assist developers in the implementation of support for Vuzix products in virtual and augmented reality applications.

Handy advances in modern gesture-based user interfaces | Science & Technology | Deutsch... - 0 views

  • After about six months of research and programming for his master's thesis, Georg Hackenberg at the Fraunhofer Institute for Applied Information Technology has managed to create what he and his colleagues are calling a 3-D noncontact gesture-based computer interface. "A special image analysis algorithm filters out the positions of the hands and fingers," Hackenberg said. "This is achieved in real-time through the use of intelligent filtering of the incoming data. The raw data can be viewed as a kind of 3-D mountain landscape, with the peak regions representing the hands or fingers." Hackenberg, who is based at the institute just outside of Bonn, said that the system is a prototype technology demo and is essentially an advanced infrared sensor on a tripod attached to a desktop computer. A 3-D wireframe displayed on the monitor serves as the desktop for the system. When someone is standing in front of the system, the infrared sensor picks up the movements of their hands, interpreting them into commands.

Playing Tag or Digital Games? Why Not Both? | MindShift - 0 views

  • What’s the difference between a computer simulation and a backyard game of tag? Quite honestly, not much – which is exactly why we, as educational media designers, have failed three decades of curious kids (with some notable exceptions). Interactive quizzes and digital flash cards may make content more exciting than their analog counterparts, but that’s a short-sighted approach that fails to get at the root problem, an extrinsic motivation when kids are already intrinsically motivated to learn. The fundamental problem is not that learning isn’t fun, it’s that we’re answering questions that kids aren’t asking (Who?, What?, When?, Where?) instead of giving them tools to experiment, build on, and share their own ideas. The problem is that we’re trying to replace teachers and parents with software rather than giving them complementary tools to help them become facilitators and coaches instead of test administrators.

The Top Ten Technologies: #3 Augmented Reality - 0 views

  • A person who wishes to experience a learning session via augmented reality would don a pair of see-through glasses that also host two tiny video cameras and a pair of earphones. A tiny computer, perhaps worn on the wrist or around the waist, would recognize the geometry and content of the user's immediate environment and overlay that environment with meaningful images and sounds for a specific purpose. From the user’s point of view, he or she would apparently see and hear other people, objects, or events taking place right in front of or around them. These augmented perceptions would appear to be completely real. In technical terms, they would be rendered by the wearable computer with light shading that takes into account both the ambient and directional light sources found in the user's immediate environment. Put simply, the augmented reality system is "projecting" people, objects, environments or other elements onto the environment around you.

How Ebooks Help The Environment - 0 views

  • Ebooks are good for the environment. Ebooks eliminate the need for filling up landfills with old books. We’re still in a period where ebooks are not an acceptable format to most book readers. That means the benefits of giving them away is not confined to the word-of-mouth from the recipients, it can result in a print book purchase by the very person you gave it to! Right now, many commercial ebooks are treated as exact (but not really exact, which is a dilemma when it comes to value perception) replica of the print version. Right down to nonsensical elements like references to page numbers within the digital text. Not every ebook is going to be for you, although if a particular ebook is what you need, it should have a lot of gainful, insightful, original data, perfectly targeted for its niche, impeccably presented, and instantly delivered. Every eBook is carefully crafted, tightly focused, and packed with good information and beneficial tips. Just download your first eBook, and you’ll see how comfortable it is to read right on your computer screen (no scrolling necessary, easy navigation) and plus it is easy to print at home. Potentially thousands of e-books can be stored on your computer or lap-top, creating a digital library of available knowledge. A publisher has numerous choices available to pick up the best format for the e-books to be produced. Although, an average end-user may simply want to read the content, the fact of the matter is that every format has its own pros and cons and the selecting of the format can be beneficial in increasing the comfort level while reading or navigating through the pages of e-books. Ebooks are great to advertise, sell, or self-publish your web site, product, expertise, or service. Ebooks are a better way to share on-depth content online. So start writing and sharing your eBook today.
