E-books: The flexible future

Interesting news from the DemoFall conference held this week in San Diego:

Plastic Logic--a company founded to commercialize electronics built on flexible plastic substrates--demonstrated a prototype e-book reader (not yet named) and announced that it plans to ship this product in the first half of next year. You can read the press release for yourself.

This particular gizmo is very attractive. It uses a large, flexible electronic paper display based on technology from E Ink (the same company that makes the displays for Amazon.com's Kindle and Sony's Reader), but the device overall is remarkably thin and light.

And the whole thing is somewhat flexible, so it won't break if it gets slightly bent in a backpack or briefcase. Flexible doesn't mean invulnerable, but it's a lot better than the brittle glass displays of existing e-book readers.

Check out this video from DEMOfall, in which Plastic Logic CEO Richard Archuleta demonstrates the prototype. I see some minor problems in the prototype's display--some dead lines and odd drawing glitches--but nothing that should interfere with the scheduled launch.

More importantly, even as a prototype, the display's contrast ratio seems to be better than that of the Kindle or Reader, mostly by virtue of the white being whiter--I'd have to make a direct comparison to be sure, though. I also see all of the critical features I want in an e-book reader: good display resolution… Read more

Samsung's showcase in San Fran

Samsung Electronics, an arm of the giant Korean company (second only to General Electric in annual revenue among conglomerates), held a press event in San Francisco last week to show off its products for the coming holiday season.

I'd been looking for an excuse to go up to the city, so off I went-- taking Caltrain rather than driving. Conveniently, the Samsung event was just a few blocks from the train station in San Francisco.

Okay, okay, I'll get an iPhone 3G!

My very first meaningful blog post here (after an introduction), from June 23, 2007, was titled "Why I'm not getting an iPhone".

Let me review my reasons at the time:

The original iPhone couldn't really do any more for me than my Palm Treo 650. The iPhone couldn't be used to connect my laptop to the Internet. No voice-memo support. No 3G networking. Not enough storage capacity. No native apps from third-party developers. No high-res screen.

Okay, what's changed?

Well, the iPhone 3G still… Read more

The Gizmo Report: NVIDIA's GeForce GTX 280 GPU-- gaming

Graphics performance improves rapidly. We can be confident that each new generation of graphics chips will be faster than the previous one, and that AMD and NVIDIA will regularly surpass each other with new product launches. I've been watching this process professionally since 1996, when I began covering graphics technology for Microprocessor Report.

As of today, NVIDIA is on top. The new GeForce GTX 280 is the fastest graphics chip you can get. See the first part of this review for details of the chip itself.

If you can get one, anyway. NVIDIA says boards based on the GeForce GTX 280 and its companion GeForce GTX 260 will be available "in quantity" tomorrow (June 17), but if previous launches are any indication, those quantities won't be enough to satisfy everyone.

And you may not be able to afford one-- a GTX 280 board with 1GB of RAM will likely be priced around $649, while GTX 260 boards with 896MB will go for about $399. (The GTX 280 / 1GB board I tested was made by NVIDIA, so it isn't necessarily representative of commercial products.)

But avid gamers won't be discouraged by these prices. Both AMD and NVIDIA like to point out that an expensive graphics card is a much better investment than a high-end CPU or motherboard if you care about gaming.

The standard of comparison for gaming performance is the number of frames per second that can be rendered for a given combination of screen resolution and quality features... or, conversely, what resolution and features can be used without reducing the frame rate below a playable level.

So in my own testing, I used frame rate as a metric for games that could run acceptably with maximum quality at the maximum resolution of my monitor (1,600 x 1,200 pixels), and quality for other games.

I did my testing with four games:… Read more

Ray tracing for PCs-- a bad idea whose time has come

Dean Takahashi sent me an e-mail pointing to a piece he wrote on VentureBeat describing statements Wednesday by Intel's Chief Technical Officer Justin Rattner targeted at NVIDIA. CNET's own Brooke Crothers covered the same story and provides additional background here.

The technology at issue relates to 3D graphics for PCs. All current PC graphics chips use what's called polygon-order rendering. All of the polygons that make up the objects to be displayed are processed one at a time. The graphics chip figures out where each polygon should appear on the screen and how much of it will be visible or obstructed by other polygons.

Ray tracing achieves similar results by working through each pixel on the screen, firing off a "ray" (like a backward ray of light) that bounces off the polygons until it reaches a light source in the scene. Ray tracing produces natural lighting effects but takes a lot more work.

(That's the short version, anyway. For more details, you could dig up a copy of my 1997 book Beyond Conventional 3D. Alas, the book is long since out of print.)

Ray tracing is easily implemented in software on a general-purpose CPU, and indeed, most of the computer graphics you see in movies and TV commercials are generated this way, using rooms full of PCs or blade-server systems.

Naturally, Intel loves ray tracing, and there are people at Intel working to… Read more

Good OLPC info from Portelligent and EE Times

I just saw an interesting piece over on the EE Times website (here) written by David Carey, president of Portelligent, an analyst firm well-known for doing teardowns of popular electronic products.

Here are some of the key points I learned from the article:

According to Portelligent, the LCD is pretty similar to previous transflective LCDs (that is, LCDs that can work from transmitted backlight or reflected ambient light) except for the arrangement of the color subpixels. I've seen nothing particularly remarkable about mine. It offers poor off-axis image quality, as I described in my first look (here), and doesn'… Read more

One new laptop per child

Last week, the One Laptop Per Child (OLPC) organization announced its new XO-2 laptop design, which will likely replace the XO-1 design I've written about before on this blog. There are images of the XO-2 on the OLPC wiki and a video clip from the announcement on Joanna Stern's blog for Laptop magazine.

The new design uses two touch-screen LCDs flanking a central hinge. This approach allows the unit to be used as a book with facing pages (shown here), as a conventional laptop using a virtual keyboard on the lower display, or as a single system shared … Read more

The Gizmo Airline Report: Virgin America

In a way, this story is left over from CES 2008, where I attended a blogger party hosted by the Parnassus Group and sponsored by, among other companies, Virgin America, the US domestic airline counterpart to Virgin Atlantic.

The party was a lot of fun, and all the sponsors did extensive giveaways. I got a flight suit from Intel and Zero G, a private company that offers "weightless" (parabolic trajectory) flights. Alas, I didn't win a Zero G flight, but I did win a free flight on Virgin America. In fact, I think pretty much everyone at … Read more

The Gizmo Report: DirecTV's HR21-700 digital video recorder

In my previous blog posts titled "Disappointed with DirecTV" (part 1, part 2) I described the problems I've had getting my DirecTV equipment upgraded for compatibility with the company's new MPEG-4 satellite broadcasts.

Today, I'll be reviewing the centerpiece of this upgrade: DirecTV's HR21-700 digital video recorder (DVR).

Since there's a great summary of the features of this product in this PDF from dbstalk.com, I won't try to rehash all the details. But I do want to describe my experiences using this gizmo, and compare it directly to my older HR10-250 … Read more
