Multi-touch display can 'see' objects too

Thu, 18 Oct 2007 16:02:20 GMT

Microsoft labs in the UK has developed a POC LCD screen with multi-touch, infrared and low resolution scanning capabilities. In an article for NewScientist.com, Tom Simonite writes:

A computer screen that also acts as a two-handed touch interface and a crude infrared camera has been developed by researchers at Microsoft's labs in the UK.

Users can operate the display with both hands, in a similar manner to the display in the film Minority Report. But this screen can also recognise particular hand gestures as well as objects placed within a centimetre of its surface.

"It can sense much more than fingers, and is essentially a low resolution scanner and camera," says lead researcher Shahram Izadi. The screen can even communicate wirelessly with other devices nearby using the same infrared technology it uses to see.

The technology – dubbed ThinSight – was developed by adding an extra layer of electronics behind a normal laptop screen. This adds a couple of centimetres to the overall thickness, but completely transforms its abilities (see a video, top right).

The screen "sees" by using a grid of paired infrared sensors and transmitters that sit just behind the backlight of the laptop's LCD panel. The sensors can form crude images when infrared light bounces off an object (see images, right). This could allow the screen to identify hand gestures or to see objects, and let them interact with onscreen images.

Sharp LCD screen doubles as a scanner

Mon, 15 Oct 2007 01:23:58 GMT

A recent article posted on Newlaunches.com reports that Sharp created a nice Proof of Concept LCD screen which could doubble as a scanner or as a method of capturing multi-touch input.

"It's all of 3.5-inches but this LCD Screen from Sharp features an integrated optical scanner that could be used to scan business cards, but also be used as a method for multi-touch input. The prototype was seen at the Ceatec exhibition. Possible uses include the ability to recognize fingers or other objects and as biometric lock on your phone. And since each pixel has a scanner it may as well be a multi-touch screen."

500GB DVD Sized Discs on the horizon

Sun, 08 Jul 2007 15:27:08 GMT

In a recent article for ars technica by Todd Haselton, Todd writes that a group of scientists working with the Institute of Optics and Optical Technologies at the University of Berlin have come up with a way to store up to 500GB of data onto a DVD sized disc. Todd Writes:

"The Project aims to implement a microholographic recording techniques which record data to nanostructures in the recording process. By combining multilayer storage and holographic multiplexing, "microholography" allows data to be stored in three dimensions. The technology works by replacing the two-dimensional pit-land structures currently found on CDs and DVDs with microgratings, which are "holographically induced" using two laser beams. In other words, instead of recording to a series of bumps and pits like standard CDs, the new technology creates three-dimensional holographic grids that can be used for reading and writing data throughout the physical structure of the disc.

In order to store data in multi-layer form, the beam is "focused to different depths inside the photopolymer layer," which means that the beam can actually be raised and lowered to write to different altitudes of the three-dimensional holograohic grid.

As you might expect, the project is bullish on its prospects. The discs are predicted to be inexpensive to produce, which the project hopes will translate into manufacturer interest. Of course, there's no word on what the recording devices would cost, and that's a major part of the equation.

Blu-ray discs currently store 50GB of data on a dual-layer disc, whereas HD-DVD can store 30GB on its dual-layer offering. Both formats have greater storage potential thanks to the possibility of adding additional layers. By 2010, we expect to see 100GB and 60GB Blu-ray and HD DVD discs (respectively) available for recording use on PCs.

Microholographic discs (MHD) are transparent and are the same physical size as CDs and DVDs, but the discs being created by the Microholas Project effectively have ten layers with five different wavelengths. The "prototype" discs are recordable and sport a 50Mb/s data rate, but the group expects an "Advanced Device" with 1TB of storage and data transfer speeds in excess of 200Mb/s by 2010."

How Big Will the Apple iPhone Be?

Thu, 07 Jun 2007 14:35:59 GMT

In an article for Business Week, Peter Burrows writes, "Few stocks trade on emotion the way Apple Inc. does. Its rip-roaring initial public offering in 1980 created the template for modern tech mania, while making Steve Jobs a gazillionaire. When the company fell on hard times in the mid-1990s, no amount of good news could pierce the cloud of doom hanging over investors. Now, with the launch of the hugely hyped iPhone in a few weeks, momentum investors are driving Apple (AAPL) shares to unexplored territory. The stock has doubled in the past year, to 122. Apple's market cap recently topped $100 billion for the first time.

Hard as it is to believe, all the excitement surrounding Jobs and his new toy may actually understate the impact of this device on Apple's fortunes. Beyond the hysteria surrounding its June 29 launch, the iPhone has the potential for adding a totally new, $10 billion-a-year business within just a few years. If Apple can expand so-called smartphones from a luxury carried by corporate road warriors into an everyday tool for the masses—combining the functions of a BlackBerry and an iPod—Apple could soon see a new growth tear."

Apple Inc.'s highly anticipated iPhone will be available June 29, 2007. The combination cell phone, media player and wireless Web-surfing device will retail for $499 and $599, depending on configuration. It will be offered exclusively by AT&T Inc.'s wireless division, formerly known as Cingular.

Microsoft Surface (a.k.a. Milan) and Similiar Touch Sensitive Applications

Fri, 01 Jun 2007 19:27:59 GMT

This week several news outlets carried articles about Microsoft Surface, a new touch sensitivie tabletop product with compelling enterprise, retail and consumer applications (see Popular Mechanics; MSNBC; FileFront; Engadget; Ars Technica; Computerworld; The Tech Report; USA Today; The Seattle PI; Telegraph; and much, much, more).

Similiar products have been developed or are being researched but have not received anywhere as much press - so for the sake of comparison and to help provide a bigger picture as to what is possible, here are a handful of links and resources to check out:

Peronsally, I'd love to see something like this integrated with an existing home theater system. Imagine an always on server networked with terminal emulations for both PCs and embeded extenders which could be installed behind bathroom mirrors, kitchen countertop surfaces, refriderators, etc..

HTPC News: DVR viewers push ad ratings - up?

Fri, 01 Jun 2007 18:30:18 GMT

In a recent article appearing in USA Today by Laura Petrecca and Theresa Howard, the latest Nielsen report data suggests that DVR recorded content is pushing commercial ad ratings up and not down. According to the article, many DVR owners do not fast forward through ads resulting in a 32% increase in ad viewership numbers within the first three days of originally airing.

Honestly, I'm one of the individuals that will not sit through the commercials. I get up and talk to the kids, take the garbage to the corner, empty the dishwasher, etc... so whether I'm in the living room watching LOST as it airs or zipping through the commercials on a DVR - at least with the DVR I'm in the same room watching the commercials as they fly by on the screen.

My wife, children and boarders on the other hand watch different shows than I do and are far less likely to fast forward through the ads. Since each of us is able to record more than one show at a time, record content that we would normally not make the time to watch and compound all of our television viewing into a single sitting our hosehold is now watching more television than ever, so even though one or two of us are fast-forwarding through the adds I can totally see how our overall exposure to commercial content would go up despite having a fast forward button.

Review: Thermaltake's Mozart Media Lab VC4000SNS

Sat, 26 May 2007 00:39:24 GMT

In an effort to make the HTPC experience more family friendly I decided that it was time to replace our HTPC's case and include it with our existing stack of home theater equipment. I wanted a case that wouldn’t glow and whistle in the dark detracting from the home theater experience and wanted to go with something that would match our existing 17" home theater components, could run 24x7 without having to worry about overheating, and could be operated by a single remote control - all this for aging HTPC system built from spare parts that I didn’t feel comfortable spending more than $100 on...

After much searching, I stumbled accross the Thermaltake Mozart Media Lab VC4000SNS at Fry's for about $129.99 (now only $99.99).

The case ships with three front side 5 1/2" drive bays with a door designed to hide all but a single optical drive. The black aluminum face plate for the optical drive is attached using a double-sided sticker which I wasn’t too excited about - although it looks far better than some of the other optical drive face plates that I've seen. The door itself is fairly heavy which is nice, but it’s on what feels like a very flimsy hinge and clasp mechanism which would have been much better executed with a magnetic clasp and or a sideways opening drawer.

This particular case does not ship with the optional VFD and Media Lab feature (for that you want to look at the VC4001SNS), so no scrolling digital text in the front of your case or remote control. If you’re like me, you don’t want any of that anyway because scrolling text detracts from the home theater experience and IR remote controls are just awful to use anyway (poor range, difficult to use behind a glass enclosures, etc). Many TV tuner cards ship with their own optional RF remotes anyway (I’m running two ATI TV Wonder 550's and an ATI HDTV Wonder card all of which ship with their own RF remotes). One thing I should mention for anyone attempting to use an RF remote is that it’s better to hang your remote antennas OUTSIDE of the case as the aluminum in the case shields too much of the signal.

The dual rear 60mm exhaust fans are somewhat loud but very much needed - DONT put this case into your Home Entertainment Center without first cutting holes to accommodate either the fans, or the entire unit. Because of the form factor of the fans, I would imagine that it would be difficult to find replacement fans for this case that are any quieter than it ships with - but if you know of any please feel free to send me a quick e-mail. In our implementation the HTPC case was too deep and I had to cut a 17" wide hole into the back for the entertainment center in order to accommodate the case.

There are two vents at the top of the case, although only one will allow you to attach a fan anywhere near it. Depending upon the amount of hardware that your running you may or may not wish to install a blowhole fan there, for my purposes the blowhole fan was overkill and I'm getting ready to remove it to cut down on the amount of noise that emits from the case.

Speaking of noise, the fans that ship with the case are noisy. With that said, the noise output of any case is always proportional to the amount of money you invest in your fans. For HTPC purposes, I would recommend sinking a good $50 on specialty fans to reduce the amount of noise pollution that your going to subject your friends and family to.

PROS:
- Excellent Price / Performance for an HTPC case at $99.99
- Beautiful 17" wide brushed aluminum case
- No flashing lights to distract you from your digital content

CONS:
- Fatter than it needs to be - for a slimmer form factor without sacrificing width check out the VC7000SNS and 70001SNS series.
- Deeper than it needs to be
- Heavy aluminum door on a flimsy hinge and clasp system that feels like its going to break off at any moment
- Cheesy but effective black aluminum stick on faceplate
- Noisy stock fans are functional but not ideal for a home theater environment

Review: Antec's Sonata III

Fri, 25 May 2007 18:46:11 GMT

This week I made an executive decision to replace the case under my desk with the Antec Sonata III (retail $129.99 at Fry's). I had seen the Sonata II as well, but opted to go with the Sonata III at a higher price point preferring the more conservative looking front console, high gloss piano black finish and higher wattage power supply.

The case comes with room for up to nine drives (3 x 5 1/2" drives, 2 x 3 1/2" drives, and four hard drives). The front facing 5 1/2" and 3 1/2" drives are accessable from the front thanks to a screwless pinch-clip system which is somewhat tacky but thanfully hidden by a hinged door. The four drive trays are a very nice touch because they come with little rubber feet to reduce the amount of noise that emits from your hard drives as they vibrate against the sides of your case. Four holes have been drilled out adjacent to the 4 hard drive bays to place an optional 120mm mounted fan to blow air over at least two, perhaps 2 and a half of up to four drives. Personally, I've lost a LOT of hard drives to heat damage, so while I like the idea of giving your customer a clean tray system that they can use to blow air over their hard dives my personal preference is to go with a smaller dedicated fan and heat sync for each drive and with the Antec Sonata III you just out of luck if you want to mount dedicated fans to your hard drives. You wont have as much space aftewards, but if your in a pinch and you NEED to use dedicated hard drive fans you can get the same noise and vibration reducing affect that the stock rubber feet give you by rigging up a rubber band array.

Out of the box, the Sonata III ships with an EarthWatts EA 500 500 Watt power supply, two front side USB ports, an eSATA port, and headphone and microphone jacks. It also comes with a washable air filter in the front of the case, however it appears as though this filter was thrown in as an afterthought as I cant see it as offering you much in the way of air filtering. I was also somewhat saddened to see that they did away with the firewire port that ships with the Sonata II case in favor of adding a next generation eSATA port that I cant use yet, but this isnt too big of a deal for me because I use firewire so infrequently that I might as well run a cable off the back of the PC when its time to upload video from my camcorder.

The case is advertised by Antec to be "whisper quiet", however there isn’t anything special about this case outside of the fact that you can step down the power 120mm stock fan that it ships with to reduce the amount of noise it makes. One thing big difference between the Sonata II and III cases that made me a bit sad was that Antec either did away with the air duct between the two models, or that the model that I purchased did not ship with the same air duct that the Sonata II on the showroom floor had. Airducts are always a nice touch in "silent" cases because they serve two purposes - they bring in air from outside of the case to cool the CPU with which ends up being about 10-20 degrees cooler than the air inside of the case. It also serves to muffel the sound of the CPU fan. I'm following up with Antec's customer service department now to see if theres anyway that I can purchase one of their air duct mufflers for the Sonata III as an added option but if they do offer one they have made it difficult for the consumer to determine which model on their web site was designed to be used with the Sonata III (no pictures on their web site).

Antec was kind enough to place a lockable latch door on the side and front of the case - however because Antec decided to place the power and reset buttons behind the door as well its somewhat of a nusance for the casual home user that just wants to turn the PC on and work. The lockable front and side doors would come in pretty handy if your looking to secure the PC from passers walking by however which would would have made the case ideal for anyone using the case to run public demo if it werent for a cheap plastic hinge which is easy to imagine breaking off after a year or two of regular usage attempting to gain access to the PC's on/off button and or drives.

In conclusion, the case has a lot of nice little features and value added extras that make it an excellent product and a more than fair price BUT there's nothing special about the case that makes it perform any better than any other standard case in terms of its ability to perform quielty and or cool devices effeciently.

PROS:
- Clean interior design
- Clean and conservative exterior look and finish
- Lots of space for devices
- Lockable doors
- Price performance
- Nice presentation of front side ports (USB, eSATA, Audio)

CONS:
- The way the case is designed, you have to decide whether you will use a 120mm fan to cool 2 1/2 of your hard drives at a time or using no cooling at all. In order to get four hard drives into my with their respective hard drive coolers I had to insert 2 under the 120mm fan and two at a 90 degree angle free floating on their sides.
- Lockable doors hide power button and reset switch
- Cheaply made plastic front door with hinges which are easily broken or snapped off
- No noticible difference in sound performance for a case that advertises that its a quetest in class model
- No air duct / muffler like the one that ships with the Sonata II
- Another case that cut the holy living daylights out of my hands while attempting to screw things in

HD News: Westinghouse shows off the Quad 2160p (3840 x 2160 pixels) HDTV

Wed, 10 Jan 2007 15:31:25 GMT

From TomsHardware.com

The 52" TV runs a super high-resolution of 2160p (3840 x 2160 pixels). In absolute numbers, the device is running a stunning 8.3 megapixels - four times more than 1080p TVs (1920x1080p) and more than twice the resolution of Dell's, HP's and Apple's 30" desktop LCDs. So, what do you get from this resolution, especially if HD DVD and Blu-ray are running only 1080p anyway?

According to Westinghouse, the TV does not really target the consumer market, but high-end industrial applications. What we saw was a demo of an oil company viewing a digital version of a mining site. And even at this very specialized application, the difference to the best 1080p we saw at CES appeared to be marginal, at least to our eyes. However, of course you do see a much clearer picture when compared to some lower-priced 1080p TVs. Westinghouse said that it has begun taking orders for the 2160p. However, the TV will not come to the consumer market anytime soon. Company officials decline dto comment on pricing, but the highest resolution on the market combined with limited availability are a good indication for one pricey TV. | more...

High-Definition Video Could Choke Internet

Mon, 15 May 2006 15:11:36 GMT

Will today's infrastructure support tommorrow's High-Definition Video? Peter Svensson, a Technology Writer for the Associated Press writes:

Most home Internet use is in brief bursts — an e-mail here, a Web page there. If people start watching streaming video like they watch TV — for hours at a time — that puts a strain on the Internet that it wasn't designed for, ISPs say, and beefing up the Internet's capacity to prevent that will be expensive.
To offset that cost, ISPs want to start charging content providers to ensure delivery of large video files, for example.
Internet activists and consumer groups are vehemently against those plans, saying they amount to tilting the Internet's level playing field, one of the things that encourages innovation. They want legislation to guarantee a "neutral" Internet, but prospects appear slim.
At the heart of the debate is a key question: How much would it really cost the Internet carriers to provide a couple of hours of prime-time TV over their networks every day?
The carriers are playing their cards fairly close to their chest, but there are ways to get close to an answer.
One data point: As a rough estimate, an always-on, 1 megabit-per-second tap into the Internet backbone in downtown Atlanta, bought wholesale, costs an ISP $10 to $20 a month, according to the research firm TeleGeography Inc. An ISP's business is carrying data from that tap to the customer.
One megabit per second doesn't sound like that much, but ISPs spread that bandwidth out over their subscribers. Analysts estimate that ISPs sell around 30 times more bandwidth to their end users than they can connect simultaneously to the Internet (the figure probably varies widely from provider to provider).

Warner Bros. to Sell Movies Over BitTorrent

Tue, 09 May 2006 16:51:19 GMT

Found this one on Slashdot this morning, martinmarv writes:

The BBC is reporting that Warner Bros. is to sell movies over BitTorrent. Disappointingly, the pricing is set to be about the same as the DVD, even though the download will only become available at the same time as the DVD release, and can only play on one machine. In distributing films via download, Warner will join the ranks of MovieLink and CinemaNow. Perhaps they should wait to see how their $1.50 experiment works out first?." From the article: "Other Hollywood studios are now likely to launch similar services. They believe movie fans will prefer to pay a reasonable price for a legal downloaded movie rather than risk illegally swapping a computer file that could contain viruses or be a poor quality copy of a film.

One of our families favorite DVD's is a copy of the 1980's version of Flash Gordon, the film is 26 years old but the kids adore it. As a consumer, I really dont care what format my video comes in as long as the quality is good and I have the ability to play it now, five years from now, and in the case above 26 years from now.
