Windows 7: Inside Multitouch

 

Friendly Computers have seen touch screens before, so what makes the ones supported by Windows 7 so special? Below is the inside scoop.

Touch screen technology may seem shiny and new but any analyst will tell you that it has been around for decades: ATMs, grocery store self-check kiosks, even museum exhibits. But what makes Windows 7 so exciting is that no computer operating system ever incorporated native support for multitouch before. The new breed of multitouch laptops and desktops with touch screens don't need extra downloads or plugins-- multitouch just works.

Multitouch's Predecessors

To be fair, Windows 7 is not the first operating system to support some form of touch computing. Vista offered single-touch capabilities in tablet mode, and pen input is quite common as well. But as much as Microsoft would love to paint multitouch as a natural progression in its operating systems, its Apple that was the real democratizer of multiple-input touch screens. Introducing now familiar gestures like pinching, tapping, and flicking, the iPhone and the iPod Touch, made multitouch second nature to many users. Apple followed up its mobile devices with gesture-based touchpads on its MacBook and MacBook Pro models in late 2008. Though it was a bit tough to get used to the integrated mouse button and touchpad, the ability to use gestures based on up to four fingers opened up new possibilities.

A few Windows-based "multitouch" systems have come out as well—namely the HP TouchSmart TX2 and Dell Latitude XT line of laptops, as well as the HP TouchSmart desktop PCs. These systems used built-in hardware and software solutions to accommodate two-finger touch (though they still couldn't support three- and four-finger gestures). But it wasn't until early glimpses at Windows 7 this year that we saw Microsoft itself respond to the multitouch trend.

How Multitouch Works

A few months before those MacBooks hit the scene, Microsoft announced its plans for multitouch at the All Things Digital conference in California. Unlike any of its predecessors, Windows 7 natively supports multitouch functionality in touch screens and is built to accommodate up to 10 points of contact. On the Engineering Windows 7 blog, the developers highlight all the ways the OS was tweaked to optimize it for touch. It's everything from making keys on the on-screen keyboard glow when your finger is covering the letter to improving high dpi support to make small links and buttons easier to access with touch.

Though the software is similar across platforms, the PCs we've tested use different hardware solutions. The multitouch laptops we've seen so far, like the Lenovo ThinkPad X200 Tablet and Fujitsu LifeBook T5010 use dual-active digitizers, meaning they have one technology for the stylus and another, called capacitive, is activated for multitouch using your fingers. Non-tablets like the Lenovo ThinkPad T400s use a capacitive touch screen only, and many more will follow this implementation (Toshiba and Acer have already announced capacitive touch panels on their mainstream laptops).

In capacitive screens, a small current of electricity runs across the surface, with circuits at the corners. Touching the screen interrupts that current. Capacitive technology only works on smaller screens, so desktops like the HP TouchSmart 600-1055 PC and Gateway One ZX6810-01 employ optical solutions. Optical sensors are set up around the screen creating a grid. The screen reacts when your finger, pen, stylus, or any other implement break one of the beams; you don't actually have to physically touch the surface to get a response.

All of the PC manufacturers that have put out multitouch systems so far have included Windows 7's Touch Pack, a software suite that incorporates applications that work with the Windows 7 kernel to use a multitude of different gestures. For instance, Microsoft Surface Collage lets you access and manipulate all your photos to create different designs on the screen. You can drag and drop images with one motion, resize or rotate them with two fingers, and scroll through the images available on the bottom pane using the flicking motion. Other games and applications like BlackBoard and Microsoft Surface Lagoon act like tutorials for multitouch, creating objectives that force you to perfect various gestures in order to win the games.

What's Next for Multitouch

Although the Windows 7 Touch Pack certainly has that gee whiz factor, the real question regards implementations for multitouch in the future. Will it change the user experience? And can we harness that potential to take it beyond a neat trick for games and fun apps? Clearly the onus right now is on software makers to come up with revolutionary ways to integrate multitouch and expand its possibilities. Some PC manufacturers have included programs built around multitouch, like Gateway's TouchPortal and HP's TouchSmart interface. While HP's includes extra functionality like Hulu desktop and HP games, these still don't bring much more to the table than a new way to interact with Microsoft's existing touch-based programs.

Whether its niche markets like education, health care, and engineering finding new uses for multitouch, or multitouch making its way onto new platforms like netbooks, there's no question that this interface can change the way we look at computing. The Engineering Windows 7 blog sums its effect up well. In it, Steven Sinofsky, the president of the Windows division wrote, "One of my favorite experiences recently was watching folks at a computer retailer experience one of the currently available all-in-one touch desktops and then moving to another all-in-one and continuing to interact with the screen—except the PC was not interacting back. The notion that you can touch a screen seems to be becoming second nature."

Magic Mouse: Oh my God—it's full of capacitive sensors!

 

Friendly Computers thought you would enjoy an inside view of the new Mac Magic Mouse and Screen.

 

Magic Mouse: Oh my God—it's full of capacitive sensors!

iFixit

You thought iFixit was going to gut the new unibody white MacBook and call it a day? Oh no—it has vivisected Apple's new Magic Mouse to see just how the "magic" happens. The gang also went ahead and disassembled the 27" iMac that came with it, too.

The first thing that iFixit discovered is that Apple really does not want you to take the Magic Mouse apart. The whole thing is held together with some really tough glue instead of screws, or clips, or anything that might make it easier to take apart and put back together. Once apart, though, iFixit verified that the entire top surface is literally covered in capacitive touch sensors—138 in all—just as Apple promised. This is what allows the multitouch gestures to be so accurate and specific over such a small surface—though it would be nice if Apple enabled pinch-to-zoom and two-finger rotate.

Though the mouse has an aluminum base, the total aluminum content weighs just 10 grams. "That's compared to 37 grams of plastic and 47 grams of batteries," according to iFixit. "Nearly half the mouse's weight comes from the two AA batteries."

The diminutive circuit and electronic components do contribute a few grams to the overall light weight of the Magic Mouse. Part of what makes the circuit so small is a Broadcom BCM2042A4KFBGH, part of the BCM2042 family of chips that integrate keyboard and mouse controller functions with an HID profile and full Bluetooth communications stack. Broadcom brags that the chip allows wireless input devices to "approach the price points of legacy-wired mice and keyboards," but this is Apple here—paying a slight premium for a "better" mouse is par for the course. Besides, what is the standard price for a wired multitouch mouse? (Answer: there isn't one!)

Of course, after discovering all the magic Apple could stuff into a $69 mouse, though, you can hardly blame iFixit for "taking apart the iMac that came with our Magic Mouse." The new 27" iMac (the lower-end Core 2 Duo version) isn't radically different that the 24" iMac model that preceded it. However, iFixit did turn up a few interesting details.

One nice addition is that Apple has doubled the amount of RAM slots; when stuffed with 4GB SO-DIMMs, you can have a total of 16GB of RAM. The new model also eliminates the 4mm aluminum bezel around the display glass cover—it goes all the way to the top and side edges, giving it a slightly cleaner appearance. The DisplayPort connection isn't wired up to allow the display to be powered separately when using the promised external source display functionality, though—the whole machine will have to be powered on for it to work.

A couple other notable discoveries: the power supply is 310W, the largest on any iMac; the SuperDrive is 12.5mm height, so it could be swapped for a Blu-ray drive if Apple ever gets over that bag of hurt; because the new back is all aluminum, the plastic Apple logo now serves as the only way for WiFi signals to get in and out of the iMac; and cooling the new machine requires two large heat sinks and three large, low-noise fans.

Technology Fails: 8 Extreme Electronic Disasters

 

Friendly Computers would like to inform you about the eight extreme electronic disasters that seems to effect each and everyone of us.

 

Let's face it: Technology seems made to stop working. Screens crack, circuits short, and power supplies abruptly conk out. It's all part of the complex and confounding ecosystem of electronics.

The worst, though, is when something really is built to break--and in the most extreme way. I'm talking fiery explosions, flying components, and acid-leaking compartments, all courtesy of bugs built right into ill-fated devices.

Sound far-fetched? Hey, we've seen some crazy stuff happen over the years. Some of it is astonishing; some of it is merely annoying. But all of it is extreme--and entirely too real.

We start with some good old-fashioned spontaneous combustion.

Combustible Computers

Laptop fire filmed at Los Angeles International AirportNothing screams "tech disaster" like a laptop on fire. Due to the intricacies of modern-day electronics, it takes only a minor manufacturing error to send your system up in flames--and not the kind generated by the jerks of online forums, either.

The most extreme example of fire-related fallout may be the massive series of recalls brought about by bad Sony batteries in 2006. Small shards of nickel made their way into the batteries' cells during production, causing numerous systems to overheat and sometimes catch fire. The recalls affected laptops sold by Dell, Hitachi, IBM, Lenovo, Toshiba, and even Apple.

By the end, a staggering 9.6 million laptop owners had been burned (figuratively speaking) by the failure, and Sony had spent nearly $430 million to replace all the defective units.

Lest you think I'm just blowing smoke up your ash, let me assure you that this danger was far from hypothetical. (Watch PC Pitstop simulate a laptop battery explosion where the temperatures soared to 1000 degrees.) A Sony-battery-powered laptop famously exploded and caught fire at the Los Angeles International Airport in 2007, and a traveler managed to catch the entire incident on tape.

Be warned: You will hear a few expletives shouted during some of the more dramatic moments. With a blast like that, I'd say they were warranted.

Fire risks have led to countless other laptop battery recalls over the years. Scientists are now working on developing a new material that could better protect the lithium ion technology and keep such short-circuiting from occurring.

Exploding iPhones

Apple's all about glitz and bang for its product launch events. Lately, however, the company has been making headlines for a different kind of spark. Reports surfaced in late July suggesting that numerous iPods and iPhones had erupted in flames and scalded their owners.

Soon after, word broke that the European Union had launched an inquiry into exploding iPods overseas. Apple reportedly claimed that some sort of improper handling led to the explosions, calling them "isolated incidents." A full investigation is currently under way.

The recent rash of complaints isn't the first time Apple's iPods and iPhones have come under fire. In March, an Ohio mother sued Apple over allegations that her 15-year-old son's iPod Touch had malfunctioned. The device, she said, exploded in the teenager's pants.

Speaking of explosions, did you hear about those new porn-star apps people are downloading?

Acid Rock

Guitar Hero controllerThe avatar for Kurt Cobain may be making Guitar Hero headlines right now, but one year ago a far more corrosive controversy was connected to the product. Rage Wireless Guitars, a series of controllers sold for use with the game, were found to have circuit-board defects that could cause battery acid to leak outside the devices.

If you're not sure how severe of a problem that could be, just think about this: Over what area of the body do most people hold a guitar? Yeah...not the best place for a chemical burn. It actually happened to at least one person, too, according to reports filed with the manufacturer and published by the U.S. Consumer Product Safety Commission.

That's one disaster I'd suspect even the great Jimi Hendrix, famously fond of both acid and fiery guitar solos, wouldn't be willing to risk.

Red Ring of Death

Xbox 360 red ring of deathIf there were an award for the most extreme-sounding technology flaw, the red ring of death would win, hands-down. Microsoft's Xbox 360 became known for it due to a widespread hardware failure that reared its ugly head in 2007. Its signature sign: three red lights blinking at you, like a disco flashback gone horribly awry.

The lights were more than a mere nuisance: They were frequently an indication of a complete hardware failure that had rendered the system useless. The issue was severe enough to earn the Xbox 360 the branding of "least reliable gaming console in recent history" from at least one publication.

Microsoft ended up spending a reported $1 billion to extend warranties as a result of the red-tinted menace, citing an "unacceptable number of repairs" as the catalyst for its decision. The company also agreed to reimburse customers who had spent their own cash trying to get their consoles fixed.

Recently, a second red-ring-like error has cropped up on some Xbox 360 systems, causing users to see a fatal error with the code "E74." Though the dreaded red lights themselves don't flash, the console is again rendered useless. Microsoft announced in April that it would offer a similar extended warranty and repair reimbursement program for anyone affected by the issue.

Melting Multimedia

Durabrand DVD playerWe all want home theater systems that make us feel like we're inside the movies--but when your DVD player actually reproduces on-screen fire inside your home, things have probably gone too far.

Wal-Mart recalled 4.2 million Durabrand DVD players this fall after discovering that the devices could overheat and set an entertainment center aflame. The company received more than a dozen reports of overheated players, at least seven of which ended with some kind of property damage to the owner's home.

Other multimedia devices recalled due to reported fires or fire risks include DVD players by Toshiba, digital cameras by Hewlett-Packard, and speaker systems by Philips Magnavox.

Retail Viruses

PC virusesWould you like a virus with that purchase? In an age when keeping up with the latest security threats can feel like a full-time job, knowing that a virus could come preloaded on brand-new technology is a real kick in the pants. Unfortunately, it's also an all too common occurrence.

In some cases an entire computer system could be the culprit. Last fall Asus announced that it had accidentally shipped a line of Eee Box PCs with preloaded viruses. A malicious file on one of the systems' hard drives would not only infect local data but also copy itself to other drives and external storage devices connected to the computer.

Viruses have been found on new digital photo frames, USB flash drives, factory-sealed hard drives--and yes, even some iPods. (Those models, it probably goes without saying, were not the "funnest ever.")

Disappearing Data

You don't need a built-in virus to leave you with a manufacturer-caused data disaster--you can also experience one of the always-popular instances of crappy-hard-drive-itis.

Plenty of people came down with the disease earlier this year when Seagate revealed that its Barracuda 7200.11 hard drives had a firmware bug that was causing widespread failures. According to user reports, the drives would die while booting up, leaving no way to access any of the data inside.

Once Seagate isolated the bug, the company offered free data-recovery services to try to make up for the mess-up. Gauging from various online discussions, though, its customers' goodwill is likely one thing the company can't recover anytime soon.

Dangerous Rides

A SegwayAs if Segway riders didn't already look goofy enough, a couple of apparent glitches started sending them flying through the air a few years back. The two-wheeled transporter, as the late Rodney Dangerfield might say, just can't get no respect.

The trouble started in 2003, when Segway had to recall about 6000 of its devices. In that case, the company found that riders could suddenly fall off when the vehicles' batteries ran low. Then, in 2006, a second recall targeted 23,500 more Segways; that time, the devices were found to be "unexpectedly apply[ing] reverse torque" (translation: "causing people to eat pavement").

Thankfully for Segway users, those problems are in the past. Now mall cops are back to relying on their own instincts--and, of course, the fact that they ride around on silly-looking stick machines--to look like total twits.

HP's New Touch Screen Laptop and All-In-Ones Debut

 

Friendly Computers  discovered the NEW touch screen HP Laptop. We thought you might be interested in today’s technology is now rising up to.

 

HP is taking touch to the people, with new touch screen laptop and desktop models, all featuring Windows 7 and some shipping on Oct. 22, when the new operating system is formally introduced.

The new multi-touch models include a number of applications that take advantage of the interface, including Hulu, Netflix, Pandora, Recipe Box, a webcam "photo booth" application, and the HP Music Store.

  • HP TouchSmart tx2 -- A laptop, starting at $799, with a 12.1-inch screen that rotates 180-degrees for use as a tablet. Besides touch commands, users can write or draw on the screen with an electronic pen. Available Oct. 22.
  • HP TouchSmart 300 and 600 -- Are the third-generation of HP's touch-enabled desktops. The 300 has a 20-inch screen and the 600 (shown) has a 23-inch display. The 300 starts at $899 and will begin deliveries on Nov. 1, with the 600 due Oct. 22 and priced starting at $1,049. Read our review of the HP TouchSmart 600.
  • HP TouchSmart 9100 -- An all-in-one desktop, starting at $1,299, which includes a 23-inch touch screen. It can be used as standard touch screen PC or tasked as a map or events kiosk in an office, hotel, or other location. Deliveries begin in December.
  • HP LD42200tm -- A digital signage device with a 42-inch touch screen. Available in December for $2,799.

Besides touch screens, HP also introduced several business desktop and laptop computers as well as new value-oriented Compaq-branded desktops and a laptop.

The Compaq Presario CQ61z (where do they get these model numbers?) costs only $399 and features a 15.6-inch screen, after $100 instant rebate. The Compaq 500B business desktop sells for $359, while the new Compaq Presario 4010f desktop sells for $309.

My take: The laptop looks very interesting and I will consider purchasing one during my next upgrade cycle. I am not wild about reaching out to touch a desktop, although HP is pushing these models for entertainment and kitchen use, where touch makes some sense.

In the kitchen, the touch screen is meant to be used with recipes and other applications that can work entirely by touch when keyboard use isn't appropriate. Verbal directions are also provided.

The new Compaq's are a welcome addition to lowest-priced laptops and desktops. The laptop competes with netbooks on price and will win some of those battles.
