Visualizing Comics on the iPad

January 27, 2010

Steve Jobs didn’t specifically talk about comics and other visually-intensive ebooks on the iPad, but it does fix many of the graphics and usability issues that severely limited the comics-reading utility of the monochrome e-readers and bulky tablet PCs that came before.

With its large color screen, slim form factor and long battery life, it may well be the reading device that comics fans have been waiting for.

While we await the iPad’s arrival, I wanted to visualize just how the iPad might work as a comics-reading machine. I fired up Photoshop and plugged in a couple of screens from the Witchblade books on WOWIO. What do you think?

XO-2: A Second-Generation OLPC Laptop/Reader

May 20, 2008

A Second-Generation OLPC Laptop

One Laptop per Child (OLPC) designer Yves Behar highlights some of the interesting concepts behind the second-generation XO machine envisioned for the 2010 timeframe on the TEDBlog.

Despite OLPC’s oft-discussed organizational problems and the usability issues of the current incarnation of the XO, the hardware designs of the current and future machines exhibit undeniably fresh thinking. The future unit’s software-configurable dual screen/touch input opens up a range of possibilities, from a proper display of two-page book spreads to task-specific input buttons configured for specific age groups and languages. Even collaboration and play by two simultaneous users becomes possible.

I’ll post a link to the full TED talk by Behar when it becomes available. Meanwhile, see more photos and additional details on TEDBlog.

Update: Here’s an excerpt from Nicholas Negroponte’s preview of the XO-2 at the OLPC Global Country Workshop:

OLPC XO and the Magic Sunshine Screen

April 18, 2008

XO display in sunlight.

Much has been written about the OLPC XO’s remarkable display, given its specifications:

higher resolution than 95% of the laptop displays on the market today [i.e., 200dpi color, which is theoretically higher than that on the iPhone — gm]; approximately 1/7th the power consumption; 1/3rd the price; sunlight readability; and room-light readability with the backlight off

Whatever other difficulties the OLPC organization may be suffering, the display is seemingly a singular achievement that could result in better handhelds, ebook readers and laptops at significantly lower cost.

But how good is the display, really?

In my earlier first look at the XO, I was quite surprised by the display’s high quality, given the low cost of the machine. With the backlight turned on and the screen displaying full color, I found it to be fairly crisp and bright, far better than the murky displays I’ve seen on some low-end laptops.

In bright daylight where ordinary laptop screens are often barely usable, if at all, the XO performed brilliantly. I loaded a pdf of my current read, Pisstown Chaos, to test the XO display’s mettle with the backlight turned off in reflective monochrome mode. A MacBook Pro in the same environment had me running for shade, since the display was barely legible. The XO text display, on the other hand, was highly readable with good contrast. It was completely suitable for reading in bright daylight (see photo at the top of this post). While the satiny surface of the screen could cause some glare issues (below), slight shifts in position were enough to alleviate the problem.

All in all, the XO display quality and daylight performance were delivered as promised. Since the technology behind the display is slated for commercialization beyond OLPC, we can perhaps look forward to a new generation of capable and lower-cost machines with the XO in their lineage.

XO Laptop as PDF eBook Reader: A First Look

January 7, 2008

OLPC XO LaptopThe XO laptop from the One Laptop Per Child (OLPC) project is a distinctive little machine. It invites children to come and play with its whimsical form: big rounded corners, bright colors, personality-laden rabbit ear (wi-fi) antennas and kid-luggable handle. With tools ranging from musical composition to writing, painting and programming, it’s intended to foster learning-by-doing and collaboration. But along with these active modes, it also is designed to be an effective ebook reader, promising inexpensive or free reading content for developing world areas where print books are often considered too expensive and rare to entrust to children’s hands.

I recently took a first look at the XO in the book-reading realm, viewing several WOWIO non-DRM’d PDFs to get a general sense of its display quality, performance and usability. Along the way, I also compared the little green guy against some of the other ebook-capable devices, including laptops, the Sony Reader and the iPhone.

Happy Surprises on Display

The XO uses a specially-designed twist on the standard LCD technology found in laptops. This variation combines high resolution, very low power consumption (the laptop is designed to run on alternative energy sources, including a human-powered hand crank), full color and low cost. The laptop seamlessly transitions between two display modes — standard backlit color (like a laptop LCD) and unlit monochrome for use in bright ambient light (similar to the E-Ink used in the Amazon Kindle and Sony Reader, but with an even higher pixel density).

XO vs. MacBook Pro: Displays Side by Side

As you can see from the photo above, the XO’s screen actually fares pretty well in comparison with a MacBook Pro and its designer-grade display (a machine which costs about 10x more than the XO). While the XO’s screen can’t match the Mac in brightness, crispness or color fidelity, it still does a very respectable job in rendering the PDF’s text and graphics. Typography is clear and well formed and images display with good detail. I’ve seen much more expensive laptops with far inferior displays. I suspect that the XO might actually outperform the Mac in bright light outdoors, thanks to its special screen — stay tuned for that test in a later post. From what I’ve seen so far, the OLPC team did a great job in hitting its multiple design objectives with this display.

PDF Performance

Given its modest, power-sipping hardware specs and child-like form, I didn’t really expect blazing speed out of this cute little machine. It lived up to those expectations and exceeded them in some ways.

Launch of the various task-oriented apps generally took a bit of patience, with load times taking many long seconds. Once loaded though, performance of apps including the PDF reader were quite acceptable. Scrolling and screen update performance were reasonably peppy, even for a large 310-page document with many embedded photos (like Letters from St. Petersburg, pictured above).

The fully variable (and responsive) zoom and scrolling controls, selectable display orientation and Transformer-like adaptability (from standard laptop configuration to a tablet-like reader) together make a very functional package for reading a PDF ebook. As with the iPhone, the ability to zoom in on PDF pages is particularly useful, since it allows the book text to be enlarged to fill the screen. This is in sharp contrast to the limitations of the Sony Reader, which has a very limited zoom that leaves some books with uncomfortably small text by wasting valuable screen real estate on blank margins.

Interestingly, XO’s reader software actually seems to be more compatible with some PDFs than that in the Sony Reader and the iPhone. For example, the latter devices (as well as other third-party PDF readers on the Mac or Windows) choke on displaying certain embedded images while the XO renders them just fine (just as Adobe Reader does).

XO compatibility vs. iPhone

XO displays an embedded PDF image while iPhone and other non-Adobe apps cannot.

As I mentioned above, PDF paging and navigation are fairly snappy. Several options are available for navigating including physical buttons for scrolling and paging along with on-screen equivalents and a jump-to-page control. In keeping with the multi-purpose nature of the machine, the physical buttons aren’t specifically labeled. As with the rest of the interface and applications, these functions are best determined through learn-by-playing-with-it trial and error, and that’s a mostly straightforward process. Bookmark functionality is notably absent. Oddly, there appears to be no way to control the cursor when the machine is in tablet configuration, so many of the onscreen controls aren’t accessible without unsnapping the screen and fishing around on the trackpad. Perhaps more experimentation will glean a more usable approach to cursor control, but in the meantime, the hardware buttons accomplish the essentials.

Head-Scratching GUI

The XO GUII tried to view the XO’s interface in terms of its intended audience — young children unburdened by the baggage of established OS conventions. Perhaps it’s impossible for me to reach such a state of innocence, but even after many of the required trials and errors, I found that the seemingly simple act of opening a PDF file was still terribly obtuse and required too many steps to accomplish. I hope to find a more direct method, since this complexity is the single biggest bump in using the XO as an ebook reader. Once the file was actually open, the reader software was easy enough to use and seemed to work well.

Closing Bits

I haven’t yet had an opportunity to read full books on the XO. In my initial play, though, it’s clear that a tremendous amount of design and thought went into creating a machine that is physically well adapted for use by children in the developing world. The biggest weaknesses are in OS usability — the all-new paradigm for a simple, task-oriented system needs some rethinking and refinement. As an ebook reader, though, the XO shows enormous potential and I’m looking forward to future developments.

Ars Technica’s Read on the Sony PRS-505

November 15, 2007

Ars Technica takes a detailed look at the latest iteration of Sony’s dedicated ebook reader, the PRS-505.

Their bottom line: “… if the Reader sounds like the sort of gadget you can’t live without and you can live with its quirks, it’s a superbly built device with a screen that will blow you away. It comes highly recommended, but only to those certain they have a use for it.”

This is largely in line with my own continuing experience with the earlier PRS-500 model. I still gawk at the e-ink screen with wonder, though I am at times frustrated by the device’s limitations. For example, during a trip my wife and I took to Las Vegas last weekend, I tried to use the Sony as a reference tool to access an ebook version of the excellent Avant-Guide Las Vegas. Unfortunately, the Reader’s slow paging and navigation made it a poor choice for non-linear, jump-around-and-find-stuff reading. For reading fiction and other works read in a linear fashion, however, I agree with Ars Technica’s assessment — the Sony Reader “…is a beautiful device that excels at what it was designed to do: display e-books.”

Green Titles, Green Books

October 23, 2007

World Meteorological OrganizationBlog Action Day and the awarding of the Nobel Peace Prize are now past, but it remains an apt time to highlight a few key books on environmental issues which are available (for free) at WOWIO.

This year’s awarding of the Peace Prize to Al Gore and the Intergovernmental Panel on Climate Change (IPCC) was met with controversy in some circles. Essential to any reasoned discussion of the merits is an actual reading of the IPCC’s report, Climate Change 2007: The Physical Science Basis — particularly the Summary for Policymakers.

The Battle over Hetch HetchyFor perspective on the larger debate over environmental policy, a look at the early clashes over preservation and resource utilization in America can provide insight on the debates that continue to this day. The Battle over Hetch Hetchy: America’s Most Controversial Dam and the Birth of Modern Environmentalism by Robert W. Righter (Oxford University Press, 2005) looks at the social and political conflict that led to the birth of the modern environmental movement and reframed the national conversation in the terms we see today.

Walden and Walden Pond, A HistoryHenry David Thoreau’s Walden (WOWIO Books, 2007) is the seminal work that gave a voice to the then-unarticulated tension between the yearning for nature’s simplicity and a modern lifestyle increasingly dissociated from the natural world. Walden Pond: A History by W. Barksdale Maynard (Oxford University Press, 2004) tells the story of the pond itself, from its days as a spiritual retreat for Thoreau and Emerson to today’s role as environmental and cultural icon.

In a nice congruity with the spirit of the subject matter, these books are all in downloadable ebook format. Despite the not-insignificant environmental cost of running the web and the life-cycle costs of the devices needed to consume the content, digital books are still an enormous step forward compared to the impacts of printed books — some 20 million trees consumed for books sold in the US alone, plus the power and waste by-products associated with their printing, distribution and disposal.

When considering the issues surrounding the environment, what are the titles that influenced you the most?
