Life Imitates Art #983745345367: The Wallscreen

One of the fictional technologies we imaged for In the Shadow of Ares is the “wallscreen”, a wallpaper-like display of practically unlimited extent which interacts with the characters’ mobile agents and other computing systems. In the scene where this technology is introduced, Amber’s mother is playing an ambience video loop of a tropical beach, which her father observes is probably too realistic for healthy morale. In other scenes, smaller data windows are displayed as needed over whatever is currently used as the background.

So, imagine my surprise this afternoon when I walked past the Microsoft store at the local mall and saw a wallscreen of sorts along all three interior walls of the place, with a tropical beach video wrapped around the whole thing in correct perspective, and with small application windows floating over the video here and there?

I didn’t react quickly enough to get a photograph of it before it switched to headshots of some unkempt programmer on a plain orange and white background, but it was very impressive and almost what we had in mind. One big difference was that the screen was only about three feet high, and at eye-level on the wall, rather than being floor-to-ceiling. It was also segmented (obviously made up of a number of individual display panels about 3′ x 6′, each of which had a tiny bit of vignetting) rather than being visually seamless.

But those are really just quibbles with what is still an emerging technology. This is 2012, and we’re already seeing technology that Carl and I posited for 2051. That’s pretty cool.

Nook vs. Kindle

I bought a Kindle back in September as a means of test-driving the e-book version of In the Shadow of Ares, mainly because I hadn’t thought much beyond Amazon when we decided to go the electronic route. I was aware that Barnes & Noble and Borders each had their own e-readers, but Kindle seemed to be the one with the broadest reach and biggest potential market.

We ended up publishing on Barnes & Noble as well as Amazon, but even so, I hadn’t even looked at a Kindle up-close until yesterday. Turns out the Nook Color is a much more impressive platform overall than the 3G Kindle:

  • The touchscreen is much easier to navigate with (especially when highlighting text or selecting a word to look up in the dictionary) than the Kindle’s “mouse box” buttons;
  • Nook, like Kindle, has built-in audio capability for playing MP3s while you read, but the player on Nook is actually a proper function of the device, and not a grafted-on “experimental” feature like it is with the Kindle — a feature which, in four months, I have never gotten to work;
  • Nook also has a built-in photo gallery function, which the Kindle (perhaps understandably in a grayscale device) lacks.

In short, the Nook is a little more like a tablet device than a no-frills e-reader.

On the other hand:

  • Despite only being a tiny bit larger, the Nook was noticeably heavier (perhaps 25-30% heavier) than the Kindle, with the Kindle already at the upper limit of a comfortably-holdable combination of mass and shape;
  • Being a backlit color display akin to those on laptops, the Nook was actually a little harder on the eyes than the Kindle with its “e-ink” display that reads more like the page of a printed book;
  • Though I’m not a big fan of Kindle’s keypad, it’s still far and away preferable to tapping virtual keys on a touch screen.

You might expect that differences like this would drive Amazon to bring a color version of the Kindle, with color e-ink, to market in the near future. Mmm…maybe not:

[Bezos] noted that developing color electronic ink remains a challenge, and while he’s seen things “in the laboratory,” the prototypes are simply “not ready for prime-time production.” He also stated that these lust-worthy, mythical displays were “a long way out,” but that the Kindle would remain focused as a dedicated e-reader moving forward.

And yet, as the links at the Engadget post illustrate, there are in fact color e-ink options out there which may be further along that Bezos suggests.

With the introduction of the iPad last year, though, there may be market pressure to rapidly evolve e-readers beyond simple, dedicated e-book devices by including features like the photo galleries and MP3 player functions the Nook already offers and better, full-featured web browsers to take additional advantage of the built-in wireless internet capabilities (wi-fi and 3G). At some point, then, there may be no real distinction between e-readers and tablet computers besides the owner’s primary habit of use.

Christmas Comes Early, Part I

Part of the reason that posting on MarsBlog has been so lackluster over the past year is that my other project, People’s Press Collective, has been claiming nearly all of my time outside of work. Since I live about forty minutes from downtown Denver, and end up down there for events 2-3 nights a week, it’s been awfully hard to find the time (or motivation when time is available) to blog from my trusty deskbound desktop PC at home.

For that and other reasons, I finally invested in a new HP dm3 laptop yesterday. Or maybe it’s a netbook. I’m not really clear on the distinction, and this one seems to be in a gray zone in between, having a dual-core 64-bit processor and faster bus than an obvious netbook and a slightly larger size, but similarly missing the optical drive of a laptop and a typical laptop’s voracious appetite for battery power. Oh, and it has a slick magnesium case, which makes it look much more hardy than the toy-like netbooks (or medical-equipment-like white Apples, for that matter).

So, with any luck, this should make posting a lot easier, and thus somewhat more frequent.

While I’ve had limited time thus far to play with it (that will come in the airport this week), I have tried out some video from the HD camcorder I picked up last month, and it is truly amazing. The desktop didn’t have enough memory to view native .MT2 files without a lot of choppiness  (and since it was RDRAM, was not cost-effective to expand), but the little laptop was all set up and ready to go, with all the right codecs already installed for Media Player. If you haven’t played around with HD video, it’s incredible how much sharper and more “real” it is than what you may be used to from YouTube or online television watching. I still may need to get a new desktop at some point to process video, but for viewing it, I don’t think I could ask for much better.

One Good Use for ISS

Whatever else good eventually comes out of the ISS, demonstrating VASIMR — and then using it to routinely reboost the station — might just be its best sci/tech achievement.

Two Tales of Technological Evolution

Tale #1: A Visit to Borders

I visited Borders over the weekend to buy a gift certificate.  The first thing I noticed when I entered the store (having not been to this particular location in perhaps six months) was the vast expanse of empty racks in the middle of the place where CDs used to be displayed.  According to the counter clerk, they were in the process of phasing out most of their CD products — all but new releases — due to the rising popularity of iTunes and other internet-based digital music sources.  “Nobody is buying CDs anymore,” she explained.

Apparently, nobody is buying books at Borders anymore, either.  Something about the book racks also struck me as odd while I was standing in line, and as I was leaving I figured out what it was: the racks had been cut back to half their length. That is, the racks perpendicular to the walls used to be made up of two oak shelving units, but the units on the end had been removed.  Now, they may plan to simply reshuffle their existing book inventory into the space vacated by CDs, but this particular change didn’t look recent – and why would they remove a good portion of the existing inventory from the floor, rather than waiting until the new area had been prepared? 

Given the company’s financial situation, it may be that I was witnessing one small step in the slow demise of the Borders chain:

Borders (BGP) has struggled for several years as the No.2 operator of book store behind Barnes & Noble. When Border’s released its last set of earnings it said it would cut the number of Waldenbooks stores from about 300 to 50 or 60. With Border’s losses, that won’t be enough. The pressure from online book operations led by Amazon (AMZN) and new e-book readers is overwhelming Borders. In the fourth quarter of last year, sales at Border’s branded stores dropped 15.3%. For the full year 2008, Borders lost $157 million on revenue of $2.8 billion. Borders recently extended its $42.5 million senior secured term loan with Pershing Square Capital Management, moving the due date to April 1, 2010. That may be the day that Borders goes away. Border’s shares trade at $1.47, down from a 52-week high of $8.02.

Tale #2: A Visit to the Dentist

Two years ago, I was glad to finally have an excuse to get rid of my last unsightly amalgam filling. Unfortunately, there was some sort of material flaw in the porcelain crown that replaced it, and today I had it replaced gratis.

Only, they didn’t replace it with quite the same thing.  Or in quite the same way.

Rather than the two-visit process I had to go through the last time, with those gag-inducing trays filled with molding putty and seemingly-endless custom fitting of the crown made from the resulting molds, I was in and out in about three hours, of which maybe ten minutes involved fitting and polishing.  Best part: no molds.

The new process involved inserting a small scanning device into my mouth before and after the old crown was removed, to create 3D images of the perfectly-fitting existing crown and the cleared-out bonding surface along with the surrounding molars.  Immediately after the second scan, a 3D image of the tooth as-it-was appeared on the screen next to my chair, the dentist made a few adjustments to add some material at certain adjustment points and then fired it off  to a milling machine in the next room — just as if she were printing a document.

About fifteen minutes later, she returned with the new but uncured crown to make a few adjustments to the fit. After about five minutes of grinding and test-fitting, it was into the curing oven for about 40 minutes. Then it was bonded in, and after another five minutes of fitting, it was done and I headed back to work.

That’s a pretty neat bit of medical technology, I think.

This is the same dentist with whom I first experienced digital X-rays a number of years ago, and who (with improved resolution on the X-ray interface) determined at my last exam that I have extra roots on all of my teeth, and not just the molars…something the new technology is showing to be surprisingly common.  Even better – she’s bringing in a 3D digital X-ray system soon, which should provide images at even higher resolution.

While I figured out the bricks-and-mortar bookstores’ days were numbered the first time I ordered something from Amazon back in 1996, the rapid evolution of medical technology is pretty surprising.
