Then there are the neither-fish-nor-fowl keyboards, such as the one that doubles as a cover on the Microsoft surface. Ramstein isn't happy with that solution, either. "Have you ever tried the keyboard?" he asked his audience. "Beautiful technology, but I don't feel anything when I press the buttons."The solution, Ramstein said, is an exceptionally thin keyboard that still manages to provide feedback to the fingers that touch it. And – suprise – that's what Strategic Polymers has developed and which he showed to his audience: the Awake haptic keyboard.The Awake is a 1.5 millimeter–thick Bluetooth keyboard, with each key being an individual EMP unit capable of providing haptic feedback when touched. Being a first-generation prototype, the Awake doesn't take advantage of the EMP units' ability to deform – to rise up and push back when touched. Instead, each key merely provides vibration as feedback when pressed.To Ramstein, though, even mere vibration is a vast improvement over, say, the Microsoft Surface keyboard, which just lies there pretty but inert. "Lovely, but I don't feel anything," he said of Redmond's inability to thrill his fingertips.

The EMP units that Strategic Polymers has created for the Awake keyboard and other prototypes are versatile li'l items. Not only can they provide vibration as feedback, but they can also deform by two to three millimeters and provide 30 to 50 grams of blocking force before being depressed, mimicking a physical keyboard. Each unit is around 100 microns thick and weighs less than a tenth of a gram.Each EMP unit can also produce sound – and not just a buzz or click, but music as well. Ramstein demoed a tiny EMP key that, when touched, played a guitar riff. Not exactly thundering bass, as you may imagine, but impressive sound quality to your Reg reporter's ears.In addition to the Awake keyboard, Ramstein demoed another prototype, the Backtouch smartphone. Less ambitious than the Awake, the Backtouch had just two of the EMP units on – where else? – its back. According to Ramstein, though, the addition of a second haptic unit to your smartphone can provide a host of benefits.

We say "second" because your smartphone alread has one haptic unit – that resonant or spinning actuator that vibrates your phone when you want to silence its ring. To Ramstein, a slow, bulky, spinning actuator is like an out-of-balance washing machine – a crude device. "When I spend four, six-hundred dollars for a smartphone, I wasn't something more than washing machine in it."When you hold the Backtouch with your fingers on the two EMP units, Ramstein demonstrated, the device can vibrate to provide turn-right, turn-left navigational clues, can be tapped in preset patterns to launch apps without having to look at the screen, or perform other tricks that clever devs might come up with.And Ramstein says his company is ready to start talking with developers and OEMs. "There are clearly opportunities for innovation and new functionality," he said. "We're just telling the world that, hey, the technology is here. Who wants to use it? Who wants to be first to market? Who has the guts to say, 'Let's bring haptics to the next level'?"

Dell’s Wyse subsidiary - the thin-client computing pioneer the PC giant acquired in April 2012 - will today show off ‘Project Ophelia’ at the Consumer Electronics Show (CES) in Las Vegas/ Ophelia is a tiny Android machine that plugs into a monitor or TV to provide “instant” access to its owner’s cloud content, the web and apps running on remote systems.Internet connectivity comes courtesy of on-board Wi-Fi, peripheral linkage through Bluetooth. The doohickey also has a USB port.Ophelia lacks a battery - power comes through its MHL connector, a Micro USB-style jack that also feeds out video signals. MHL supports 1080p video and HDCP content protection. Many TVs and monitors have MHL, and there are plenty of MHL-HDMI adaptors out there too. It’s a technology widely used in HTC, LG and Samsung phones.This being a Wyse device, the gadget is ready to run as a thin-client to tap into applications hosted on servers and desktops running Citrix, Microsoft or VMware.

Dell’s notion is that office drones on the road and folk away from home will want to access their files remotely but don’t necessarily have access to carry a laptop or a tablet around, or need to make use of a large display. It’s pitching Ophelia as a handy-to-stow alternative ready to be hooked up to a big screen, although the user will still need to find a Bluetooth mouse at the very least to be able to operate the gadget.“Project Ophelia transforms ordinary displays into a window to entertainment, communications and a person’s own personal cloud,” puffs the company. “Mobile devices have small screens, tablets and PCs aren’t always convenient to haul around, and all these devices require batteries that can run down.”Ophelia - the go-to-market name is TBD - will be out sometime before July, Dell said. Or you can get something similar from a dozen or so Chinese suppliers for 40 quid via eBay. Nvidia has plugged a critical flaw in its graphics card software that allowed hackers to gain "super-user" access to vulnerable PCs over a network.

The Nvidia GeForce display driver update, version 310.90, also features a number of other bug fixes and performance upgrades."The (cliquez ici pour suivre le lien)">vulnerability allows a remote attacker with a valid domain account to gain super-user access to any desktop or laptop running the vulnerable service," HD Moore, the developer of Metasploit and chief security officer at Rapid7, told SecurityWeek."This flaw also allows an attacker (or rogue user) with a low-privileged account to gain super-access to their own system, but the real risk to enterprises is the remote vector," he added.The critical privilege elevation flaw was discovered by UK security researcher Peter Winter-Smith.The driver update can be downloaded here. The accompanying summary of the update mentions a "security update for the Nvidia Display Driver service (nvvsvc.exe)" in one sentence but concentrates on claimed performance improvements for gamers, particularly fans of Call of Duty: Black Ops 2 and Assassin's Creed III.

Yes, hardware wasn't quite as profitable as software or services, but this was years ahead of the recession, before the advent of the iPhone and iPad; sales of PCs were ticking along and the imperial success of the netbook was yet to come.And while IBM didn't sell Lenovo a lemon at the dawn of the noughties, eight years later, China's PC maker finds itself in a challenging situation.Worldwide sales of PCs are falling but Lenovo's sales seem to be falling more slowly than those of its rivals - to the point where, depending on whether you believe the numbers rattled off by Gartner or IDC, Lenovo is now the world's number one or number two seller of PCs. Its closest competitor on the PC sales front is Hewlett-Packard, which took the second spot in Gartner's list and first place in IDC's.At the top end of the computer and devices market there's high-priced competition from Apple, thanks to the iPad. At the other end is everybody else, each firm aiming its gear at the mass market and competing ruthlessly on price.The mass market is the traditional playground of PC makers; they have long argued that Macs are for computer snobs, who are keen lighten their bulging wallets by paying the Apple tax.

However, current market forces are eating low-end players alive - making the top end a lot more attractive.In the world of mass-market PCs, which Lenovo and pals have called home for so long, sales aren't just falling, the value of what's being sold is too - and profits and margins are being squeezed to their limits. Just last month Gartner had to re-forecast predicted IT spending in 2013 taking $40bn off its initial forecast, because more low-priced devices are entering the market and being bought.The prime culprit is Google's Android, an operating system that comes minus the licensing tag - a fact that means PC- and device-makers get a cost advantage in manufacturing that they can pass on to the consumer.In some ways this helps, as margins are squeezed, but Android is also the cuckoo in the nest, which is eating PC-makers from the inside out on price.Lenovo's answer is to re-organise into two business units to sharpen focus on the high and low end; it is currently re-organising into The Lenovo Business Group and the Think Business Group.

Lenovo chairman and chief executive Yang Yuanqing calls this a "defence + attack double fist strategy” that will see Lenovo “maintaining gains and continue to achieve new breakthroughs".The Lenovo Business Group will offer "mainstream consumer and commercial desktop computers, laptop and [a] tablet computer business" and "global expansion" for the Lenovo's smartphone and other connected devices like Smart TVs, which are also starting to run Android.But it's already an aggressive market - this is the market Gartner reckons is being driven down on price, thanks to Android.But the Think Business Group is in with a chance to grab a bit of that high-end loot. TBG is home to IBM's best recognised PC brand: the Think Pad.The problem for Lenovo is the same problem that has afflicted every company that has launched a product aimed at the iPad market. It's the problem that has already hit Research in Motion, Motorola and HP - all of which believed it was sufficient simply to launch their own tablets and hope that the dollars would follow. But the dollars didn't follow and each company was left embarrassed. The problem is: you can't just turn up and expect people will be dumb enough to forget Apple.Over on phones it has been a different story, as Samsung has learned... The South Korean company has buried the iPhone with the Galaxy. This is the model Lenovo must follow. Samsung, like Apple before it, succeeded because it delivered compelling and polished products that changed the market while being reliable and dependable.

The question is whether a PC maker like Lenovo, like any OEM over in Silicon Valley, has the creative mind and the flexible design and manufacturing processes to break out of the PC assembly line business. No redrawing of the corporate reporting lines will provide these. Product Round-up Monitors don’t age very well; growing, as they do, dimmer and yellower as time passes. Premium panel technologies are now also considerably cheaper than they once were, so if you haven’t updated your display in a while, the chances are it’s now more than a little bit rubbish.I’ve taken a look at ten of the best affordable monitors available with an eye to the on-line prices you can expect to find, as there are definitely some bargains to be had. Each monitor in this selection has rather different strengths and features but all offer a full HD 1920 by 1080 resolution and measure up at roughly 24 inches. Some offer super-fast response for games and others, supreme picture quality while some are simply stylish. It’s effectively your computer’s face, so why not make it better-looking?
