How 3D is Nintendo's "Glasses-Free" Game System?

While at E3 in LA this week, I got to spend some more time playing around with the Nintendo 3DS, the upcoming "glasses-free" 3D version of the popular handheld game system.  Nintendo was showing a few limited applications of the device, including the camera feature, two playable games, and some video demos.   


The 3DS looks like the current DS, with two screens – a touch screen on the bottom half of the device, and the 3D screen on top.  One of Nintendo’s challenges will be marketing this device to the general public, since you can’t really appreciate the glasses-free visuals unless you’re eyeballing it live.  This is why, at the press conference, Nintendo quickly dispersed dozens of models into the audience to let attendees check it out first-hand.  During my extended time with the 3DS later, I tried to put myself in the mind of a kid picking it up for the first time – and heard a resounding “awesome!” echo in my brain.  But my grown-up brain had a few quibbles.

Though Nintendo isn’t revealing technical specs yet, the 3D image is rendered on the top screen of the 3DS without the need for the Real-D or Dolby glasses used at homes and theaters.  The 3D image isn’t as in-your-face as one you might find in a theater, but the depth and precision is striking.   Two camera lenses on the back of the device are used when you snap 3D photos, and the effect is mesmerizing (even when I just snapped my outstretched hand). A thumbpad on the left side of the 3DS lets you shift the image to change perspective. 

Impressed by the still images, I dove into the gameplay.  Nintendo showed two  flying games, which feature  a long depth of field.  Zooming around the sky while firing off torpedoes into the distance looked amazing.  The moments when other ships drifted behind mine were wow-worthy. At several points in the games, however, I found my eyes slipping momentarily out of focus – sort of like the feeling I used to have reading those Magic Eye 3D books several years ago.  The Nintendo rep showing me the device explained that “everyone’s eyes are different" (really?), which is why the 3DS includes a slider on the right side of the device allows you to toggle between a 3D and a 2D version of the images.  I supposed the occasional toggling is a small price to play for not having to wear glasses (let alone find them hidden or broken in your sofa cushions). 

Overall, the 3DS is extremely impressive, and surely will be a must-have for grown up game geeks and schoolyard players.  But…it’s just a start.   I’m surprised though that Nintendo didn’t demo games designed more specifically with 3D in mind – rather than 3D versions of familiar franchises.  The Nintendo Wii launched with specially designed titles (like Wii Tennis) that genuinely redefined what videogames can be.  It’s  disappointing that Nintendo didn’t make the same effort when debuting the 3DS.  I’m sure visionaries like Nintendo designer Shigeru Miyamoto and others are dreaming up all new kinds of game experiences that will exploit 3D for its fullest potential.  But for now we’ll have to wait to see if and when they deliver. 


Hands-On With the Hottest New Games

Day Two of the Electronic Entertainment Expo here in Los Angeles, and that means exclusive hands/eyes-on time with the groundbreaking new technologies at the show.

First up, Kinect - Microsoft's motion-sensing camera that promises "controller-free" gaming.  Yesterday, I got to hear Microsoft's PR spiel on Kinect at the opening press conference.  But you can't really get a feel for these new interfaces until you try them out for yourself.   So what's the verdict?  The first few of the half dozen demos I tried out today left me feeling a little bit...meh. 

Kinect Adventures, a sort of extreme outdoor sports obstacle course with rafting and roller-coastering, aims to get players jumping, smacking, ducking, and leaning for points.  But a noticeable lag time between my movements and my avatar's on-screen gave the action a gimmicky feel (something, although, that will probably go lost on the target audience of families and kids).  Sadly, Kinectimals - the virtual tiger pet game - failed to impress hands-on for the same reason.  It gets high points for cuteness, but the most interactive moments - like reaching out to "pet" the cat - felt canned, especially when the animated representation of your fingers on screen wiggle out of cue.  Your Shape:  Fitness Evolved fairs much better, delivering a convincingly precise exercise training experience.  For example, the yoga routines measure the (fairly) exact angles of your squats as you stretch, scoring/correcting you on-the-fly.  Look for this to be big with the Wii Fit home fitness crowd.  The best of the Kinect bunch is definitely Dance Central, a boogie-along-with-the-avatars game that's giddy enough to distract players from any inaccuracies. 

Over at Sony, the much-hyped 3D games were also hit and miss.  More than once, it took some adjusting to get the 3D viewing to snap into focus - and moving around while gaming didn't help.  Killzone 3 in 3D, however, was suitably awesome once it clicked in, proving that fast action videogames could be a huge sell in getting consumers to adopt 3D televisions in the years to come.  While Sony's motion-sensing controller, called Move, feels more responsive than the wireless remote for the Nintendo Wii, it also feels like a bit of a me-too afterthought.  A gladiator game delivers the most pow, as you use two Move controllers to wield your shield and hammer.  No games come close to the aha moment delivered when Nintendo first demoed Wii Tennis here at E3 a few years ago. 

In fact, some of the best games at E3 have nothing to do with 3D or motion-gaming.  Little Big Planet 2, the sequel to the wildly creative Playstation 3 game, adds even more dynamic tools for do-it-yourself players (who can now design their own strategy and action mini-games too).  Rock Band 3, the upcoming music game from the Cambridge-based developer Harmonix (whom I profiled for Spectrum magazine), adds a real MIDI keyboard and multiple vocalists for tracks.  During a behind-closed-doors preview, I got to try out maybe the coolest peripheral ever - the Fender Mustang Pro, a real MIDI guitar controller with 150 buttons.  Players will also be able to plug in an actual electric Stratocaster guitar, since the game can now parse which strings you press. Yes, this is the school of rock for the Xbox generation.  And who says videogames don't teach you anything of value?

Early Videogame Buzz at E3

The first (official) day of E3 videogame convention started today, and already there are clear standouts:3D and motion-gaming, as I anticipated. Here’s my initial take: 


Formerly known as Project Natal, Microsoft’s controller-free, voice-command, motion-sensing cam captured much of the buzz after the big press conference yesterday.Is it cool?Yeah – though not entirely for the reasons you expect. Hardcore gamers have been (loudly) grumbling about whether a wave-your-hands-to-move interface will have any relevance for them. Maybe it won’t. I’d still rather play shooters like Halo Reach with the precision of an old-fashioned controller. But hardcore gamers aren’t the sell here. Instead, look for casual gamers to flock to this device. And there are three games here that are reason alone to buy the Xbox 360 add-on. First, Kinectimals. This kid’s virtual pet game is in the vein of Nintendogs. The demo shows a girl playing with a cuddly tiger who jumps when she jumps, purrs when she tickles it, and whimpers when she hides off camera – a must-have for girls under 12. The next Kinect hit, Your Shape: Fitness Evolved.This is clearly Microsoft’s Wii Fit killer for cardio and yoga enthusiasts. The game measures you instantly down to your waist size and arm length, tailoring workouts accord to your progress. But the biggest smash – Dance Central, a dance game from Harmonix, creators of Guitar and Rock Band. Dance games like Dance Dance Revolution have a long history of success, particularly in Japan, and Dance Central has all the makings of a global phenomenon. Instead of dancing on pads, you move freely in the game, mimicking the moves of dancers on screen. Score! But my personal favorite Kinect innovation – making my TV viewing remote control increasingly obsolete. In addition to playing games, Kinect lets you choose, view, and manage your videos and films without looking for the clicker. That means all the streaming Netflix and Zune content to the Xbox 360 can be navigated just by flicking your hand or voicing commands. And with ESPN striking an (awesome) deal to bring 3500 on-demand live sport events to the Xbox 360, it means no more rifling for the remote under your couch cushions.

Nintendo 3DS

Yes, it looks like real 3D. I got an early look at the new Nintendo 3DS handheld game unit, the 3DS, and the glasses-free 3D actually works. It’s not quite as in-your-face as, say, watching Avatar, but it definitely pops out at you. Nintendo is touting the beefed-up graphics processor and the two screens of the unit, which enable them to pull off this spectacle-free spectacle. I’m impressed.

Sony Playstation 3D

Because Sony has end-to-end 3D technology, from the game systems to the 3D TVs, the company rightly put its muscle behind this innovation. The demo of this first person action game, Killzone 3, looked incredible – from the waves splashing up against the arctic bergs, to the blood dripping down the contours of your goggles. It almost made me upset that I didn’t buy my 3D TV yet after all. Of course, a lot of people will make noises about how few consumers have 3D yet, but all in due time. Killzone 3 proves that some games – particularly first person shooters – will look waaaaaay better in 3D, since this genre of games has always been aping 3D since its inception. Doom 4 in 3D please.


How Much Water Did It Take To Make Your Cellular Phone?

IEEE Spectrum’s June special report on the water-energy nexus reminds us of how little we know about how much clean water is required to enjoy the comforts of the modern age. Take for instance the electronics we use every day. Just how thirsty is the chip making industry? Extrapolating from recent reports that a new ultrapure water system that GE is designing and building for a Global Foundries semiconductor fab under construction in upstate New York will need to filter millions of liters of water a day, the answer is: very thirsty.

Why? Chip making processes require each wafer to be rinsed more than 30 times. And while the reports made no mention of how much of the facility's wastewater will be recycled, Intel boasts of having received U.S. Environmental Protection Agency awards for reclaiming 25 percent of its wastewater.

Major Chip Makers Expand Production in the West

A couple of major chip makers seem to be bucking the trend that has seen most of the world’s manufacturing firms scramble to set up shop in places where there are leagues of technically skilled people willing to accept a fraction of the prevailing wages in the United States and Western Europe. Globalfoundries, which was already in the process of building a chip fabrication facility in upstate New York, recently announced that it will tack on an additional 27 800 square meters of clean room space. The move, which will allow the fab to turn out 60 000 22-nanometer wafers per month when it is completed in 2012, will mean dozens of new jobs in the area. The company also announced an expansion of its Dresden, Germany, facility where it will eventually make 28 nm wafers. The output there is slated to reach 80 000 units a month.

Meanwhile, Samsung is readying a new production line at its Austin, Texas, semiconductor manufacturing facility that will create 500 new jobs. The addition, which will be the site of 45-nm LSI logic chip wafer production, is expected to come on line in 2011.

These moves come after Intel’s 2009 announcement that it will spend US $7 billion to upgrade its Oregon, Arizona, and New Mexico factories so they can do 32-nm production. Intel says the investment will create or save about 7000 U.S. jobs.


The Videogame Circus Begins

Last night in Los Angeles, Microsoft herded journalists into a big room, dressed them in weird ponchos, and set loose a troupe of Cirque du Soleil dancers overhead.  

Oh yeah, and it all had something to do with videogames.

The occasion was the kick-off of the annual Electronic Entertainment Expo - the bachannalian convention better known as E3.  Microsoft wasted no time hyping The Motion Capture Camera Formerly Known as Project Natal, now christened Kinect.  If you've been reading this blog, then you know that Kinect isn't new - I was one of the journalists who got a hands-on preview of it at last year's E3.   But now it's going wide - expected to hit the Xbox 360 in November.  There was little in the way of games shown last night, but I'll be at Microsoft's press conference today to hear/see more.

Despite the fact that no new videogame consoles are hitting this year, the convention promises to be heavy on hardware hype.  The Kinect camera will be getting much of the buzz, along with Nintendo's new 3D handheld system, the 3DS and, in third place, Sony's after-the-fact motion sensing Move controllers.  Yes, this means a host of new kinds of game experiences on the horizon - but the horizon may be further off than it seems.  A true golden age in gaming - like the one first coined in the 80s - really has nothing to do with technology.  It's about iconic and addictive games that don't necessarily look or feel that impressive at all (see Pong, C64, etc.). 

The last "revolution" in gameplay came with the Nintendo Wii, and some of the most unlikely and ubiquitous titles for that game were not even a faint dream at launch (Wii Fit, for example).  I suspect it'll be several months before we really see games that deliver on the HUGE hype behind Kinect and company.  

Cheap, wireless, automatic backyard sprinkler control

Maybe it’s just because as the editors of IEEE Spectrum have lately been paying a lot of attention to the problem of water conservation, and the coming clash between water and energy, but right now any easy, inexpensive way to cut back on water usage seems like a good idea to me.

And Digital Sun, a startup company based in San Jose, Calif., purports to have such an idea (I have yet to try it for myself). They presented their product, at Launch: Silicon Valley, an annual conference sponsored by the Silicon Valley Association of Startup Entrepreneurs, held Tuesday, June 8, in Mountain View, Calif.

Digital Sun has developed a system that includes sensor that goes into a hole you cut in the dirt with a wireless receiver that you attach to your existing sprinkler control box. The sensor uses a proprietary wireless communications protocol over a very low power 2.4 GHz signal, sent through the dirt, to override the sprinkler timer if it’s due to start watering cycle already damp ground. Digital Sun CEO Dale Hitt explained the technology to me, in the video below.

Right now, the basic package—one sensor, the receiver, and a tool that cuts a hole in the ground for the sensor—retails for $200. The company attended the Launch conference in hopes of attracting enough venture investment to move their manufacturing offshore, which would enable them to cut their price below $100 and get into Home Depot and other low-cost retailers.

I think they’re on the right track. In fact, I might suggest their product to a few neighbors, whose sprinklers seem set to “create swamp” rather than “water lawn.” Just a thought.

Competition for E-Ink?

The e-reader market took the company E-Ink and its low-power, easy-on-the-eyes digital paper technology mainstream. But no one says E-Ink is perfect; the displays, to date, don’t do flexibility or full color well. And they aren’t cheap enough to move into budget-conscious applications, like the long-dreamed of grocery store shelf tags that could be updated remotely to display new prices.

E-Ink and its brethren continue to advance down their technology development paths. But a startup company based in Saratoga, Calif., says they’re heading in the wrong direction.

The folks at Zikon have figured out a way to make electronic ink out of nanoparticles that don’t need to be packaged in microcapsules to work. Encapsulation, they say, is one of the big reasons today’s electronic ink-based displays are expensive to produce. And Zikon’s unencapsulated particles are so tiny that instead needing a liquid medium in which to float, they can move around in a porous material, kind of like, well, paper.

That means that E-ink can create a high contrast display by using a white background. And that the manufacturing process is similar to printing, a cheap and well-established method.

Zikon says this new form of electronic display may have applications beyond shelf labeling and flexible reading materials, like color-changing fake fingernails. Really. Zikon’s CEO Mateusz Bryning tells me about the technology—and the fingernail application, in the video below, recorded at Launch: Silicon Valley, an annual conference sponsored by the Silicon Valley Association of Startup Entrepreneurs, held Tuesday, June 8, in Mountain View, Calif. Zikon was one of about two dozen companies selected from 400 applications to present its ideas to the venture capital community at the conference.

Bursts of Low-intensity Ultrasound Make Neurons Fire.

Neuroscientists are well accustomed to making neurons fire artificially by shocking them and doping them. Indeed it's the backbone of most neurological therapies. Now, it seems, we can do it with just sound.

Bioengineers at Arizona State University published an article in Neuron today (it's free online) in which they demonstrate the ability to stimulate neuronal action potentials (electrical impulses) by applying bursts of low-intensity ultrasound to the mouse brain. Other people have shown that this is possible to do in brain tissue, but the Arizona lab claims to be the first to make it work through the skull in a live animal.

If such a technique is to become therapeutically viable it will have fierce competition from another stimulation strategy that excites neurons through the skull with either direct current or electromagnetic induction (called tDCS and rTMS respectively). These two approaches have spawned a veritable deluge of research, raising hopes of alleviating migraine pain, depression, and attention deficit disorder, to name just a few. Despite a lot of encouraging results, rTMS and tDCS have pretty terrible spatial resolution and this is precisely where ultrasonic stimulation may be able to compete and contribute.

In the experiments published today, the researchers looked at spatial resolution in two different ways. First they stimulated areas of the brain that control movement and found that they could isolate specific muscles. Point pulses of ultrasound at one part of the motor cortex and the paw twitches, move it slightly and the tail jerks. This alone is more precision than has been shown with electrical stimulation. (There's a link to a movie for those who can stomach research on restrained mice).

But the group went further and analyzed the biochemistry of the brains to see exactly what parts of the tissue had been stimulated. Their results suggest that ultrasound can be used at a resolution that is about 5 times better than rTMS. They also estimate that they could successfully use 0.5 MHz of ultrasound to stimulate brain regions that are 1 millimeter wide and less.

However, it's not as clean as all that. The sound waves seem to reflect in some instances and can stimulate the tissue unpredictably.

As of yet, there is no solid hypothesis to explain how the ultrasonic waves cause neurons to fire. The most convincing theory is that it produces enough mechanical stress on ion channels to open them. Normally these channels remain gated until the electrical potential across the neuron's membrane changes enough to fling them suddenly open and initiate the cascade effect we call an action potential.

Whatever the mechanism, the side effects on the cell seem to be minimal. Basic tests for cellular death showed no increases after applying the ultrasound.
