davidy writes "I have photographed some pages of a book for reading on my PDA. This is much faster than scanning and I don't have to carry the heavy books. However, the photographed books are not as nice: curved, skewed, and shadowed, as opposed to the much flatter, cleaner scanned books. I have searched for software that can flatten the pages for better reading on the PDA. So far I have come across Unpaper and Scan Tailor. Unpaper doesn't seem to have a windows GUI, and Scan Tailor doesn't unskew well. I remember reading about Google's technique of converting books to e-books with a camera and a laser overlay. Is there any home user software that can do a similar job without the need for a laser overlay or other sophisticated (and patented) technology?"

TechCrunch has an article about a startup called iMo, which aims to enable control of any PC game using an iPhone or iPod Touch. The idea is to reduce the need for gaming peripherals while you're on the move, and make motion-control available to more players. Quoting: "The system also features onscreen controls for the iPhone and iPod Touch, as not every PC game will benefit from using things like the accelerometer, obviously. This all works via both Bluetooth and WiFi connections between your device and your computer. The plan is to offer iMo in the App Store for $0.99; the first version should be available new in the App Store. And long-term, the company hopes to make it available on other mobile platforms as well, including Android. And ultimately, they'd love to include support for gaming consoles as well, like the aforementioned Wii, the PS3, and the Xbox 360."

andylim writes "Recombu.com has pitted the iPod Nano's video capabilities against an iPhone 3GS, a Nokia 5530 XpressMusic and Flip Mino HD. This simple test shows how the camera deals with motion, colour and audio. The iPod Nano's camera seems to offer a basic yet decent video experience and some might say delivers a higher picture quality than the iPhone 3GS's camera. What's interesting is how well it deals with close-ups."

Danny writes to tell us that Obscura Digital has launched their largest multitouch wall yet. 18 feet of multitouch surface is divided to allow six simultaneous users, each with their own targeted audio. The massive wall can handle 100 hi-res images and videos together in real-time. Relatedly, Atmel recently announced the release of their "maXTouch" technology, which delivers a capacitive touchscreen that boasts a refresh rate and signal-to-noise ratio that's 66% better than their nearest competitor. Hopefully this means massive multitouch surfaces will be coming into my home sooner rather than later.

Hugh Pickens writes "With the perspective of forty-plus years since my graduation, I would say the single most useful course I took in high school was a business class in touch-typing that gave me a head start for writing and with computers that I have benefited from my entire life. So it was with particular interest that I read Gordon Rayner's essay in the Telegraph proposing that schools add a mandatory course in touch typing to the cornerstones of education: reading, writing and arithmetic. 'Regardless of the career a child takes up when they leave school, a high percentage of them will use a keyboard in their daily work, and all of them are likely to use a keyboard in their leisure time,' writes Rayner. 'Touch-typing would help every child throughout their lives — so why are our schools so blind to this?'"

djk1024 writes "I've just filed for a patent on a new approach to motion capture that is simple, cheap, easy, accurate, and portable. It's RF-based, accurate to 1 mm, and simple enough that a sophisticated hobbyist could build one in a couple weekends from plans and standard electronics. So now what? I quit my job and have been working on this full-time for the past couple of years; now I'm out of money so can't continue development on my own. I'm also not an electrical or RF guy so I can't carry out my own independent development on the electronics. I'm quite frustrated at this point. I've been in the software development field for over 30 years and have gone through a large number of startups, but always just as the head techie, and always as part of a team. This doing it alone sucks. I would love some advice on how best to go forward."

Hugh Pickens writes "Scientific American reports that a new device called 'BrainPort' aims to restore the experience of vision for the blind and visually impaired by relying on the nerves on the tongue's surface to send light signals to the brain. BrainPort collects visual data through a small digital video camera and converts the signal into electrical pulses sent to the tongue via a 'lollipop' that sits directly on the tongue, where densely packed nerves receive the incoming electrical signals. White pixels yield a strong electrical pulse and the electrodes spatially correlate with the pixels, so that if the camera detects light fixtures in the middle of a dark hallway, electrical stimulations will occur along the center of the tongue. Within 15 minutes of using the device, blind people can begin interpreting spatial information. 'At first, I was amazed at what the device could do,' says research director William Seiple. 'One guy started to cry when he saw his first letter.'" There is some indication that the signals from the tongue are processed by the visual cortex. The company developing the BrainPort will submit it to the FDA for approval later this month, and it could be on sale (for around $10,000) by the end of the year.

Slatterz writes "Logitech has introduced new mice that use two lasers rather than one to work on a variety of previously unusable surfaces. The first laser picks out imperfections in the surface of a tabletop while the second laser focuses on microscopic imperfections highlighted and uses those to direct the cursor. The technique, dubbed dark field microscopy, allows mice to be used on almost any surface, including glass (as long as it is more than 4mm thick)."

ericatcw writes "Apple Inc. may still be coy about whether it plans to launch a touch-screen tablet computer this year, but Windows PC makers are forging right ahead. In the past three weeks, five leading PC makers have announced or been reported to confirm plans to release touch-screen PCs in time for the multi-touch-enabled Windows 7, reports Computerworld. Many appear to be using technology from New Zealand optical touch vendor, NextWindow, which already supplies HP's market-leading TouchSmart line, and Dell's Studio One. NextWindow's CEO says the company is working with partners on 8-10 products set for launch within two months, in time for Windows 7's October 22nd release."

An anonymous reader writes "Scientists at HP have developed a technique to detect creases in photographs using standard, unmodified flatbed scanners. Once correctly scanned into a computer, software can determine where the photograph's defect is, and artificially correct it to remove any trace of a crease or fold. The result is a spotless JPEG scan from a creased photo, with absolutely no modified hardware and no technical know-how required on the part of the user." They're using multiple light sources to do this, in a way that reminds me of last year's description of 3D image creation using an ordinary digital camera.

kaychoro writes to mention that at least one privately held bank is planning on removing a little bit more legwork for the consumer by allowing the electronic submission of paper checks via a new iPhone app. The app would allow users to take a picture of the front and back of the check and submit that to the depository. "Customers will not have to mail the check to the bank later; the deposit will be handled entirely electronically, and the bank suggests voiding the check and filing or discarding it. But to reduce the potential for fraud, only customers who are eligible for credit and have some type of insurance through USAA will be permitted to use the deposit feature. Mr. Peacock said that about 60 percent of the bank's customers qualify."

Krystalo writes to tell us that Microsoft hardware has an interesting demo of a pressure-sensitive keyboard they have designed. While there are no currently announced plans to turn this into a shipping product, there are many cool uses that one could imagine a device like this providing. "The device will be put to use in the first annual Student Innovation Contest in Victoria, Canada, where contestants will be supplied with a keyboard prototype and challenged with developing new interactions for it. Contestants will demo their creations and attendees will vote for their favorite at the conference on October 5. $2,000 prizes will be given to the authors of programs deemed as the most useful, the best implementation, and the most innovative."

Harry writes "For every blockbuster of the mouse world (such as Microsoft and Logitech's big sellers) there have been countless mice that flopped, or never made it to market. Mice shaped like pyramids; mice shaped like Mickey; mice that doubled as numeric keypads or phones. Even one that sat on your steering wheel. I've rounded up some evocative patent drawings on twenty notable examples."

An anonymous reader writes "Tech Review has a roundup of some cool, experimental new interfaces being shown at SIGGRAPH 2009, underway in New Orleans this week. They include an amazing 'touchable holograph' display, developed by a team in Japan, which uses an ultrasound device to simulate the sense of touch as the user grasps objects shown in 3D. The other ideas on display are Augmented Reality for Ordinary Toys, Hyper-Realistic Virtual Reality, 3D Teleconferencing and Scratchable Input Devices. If this is the future of computers, sign me up." The conference has also seen the release of OpenGL 3.2 by the Khronos Group.

Anonymouse writes with this excerpt from SemiAccurate: "Apple keyboards are vulnerable to a hack that puts keyloggers and malware directly into the device's firmware. This could be a serious problem, and now that the presentation and code (PDF) is out there, the bad guys will surely be exploiting it. The vulnerability was discovered by K. Chen, and he gave a talk on it at Black Hat this year (PDF). The concept is simple: a modern Apple keyboard has about 8K of flash memory, and 256 bytes of working RAM. For the intelligent, this is more than enough space to have a field day. ... The new firmware can do anything you want it to. Chen demonstrated code which, when you put in a password and hit return, starts playing back the last five characters typed in, LIFO. It is a rudimentary keylogger; a proof of concept more than anything else. Since there is about 1K of flash free in the keyboard itself, you can log quite a few keystrokes totally transparently."

eldavojohn writes "MIT Researchers have unveiled a new potential replacement for barcodes. Using an LED covered with a tiny mask and a lens, these new bokodes can be processed by a standard mobile phone camera and can encode thousands of times more information than your average barcode. New applications are being dreamed up by the team. Dr. Mohan of MIT said, 'Let's say you're standing in a library with 20 shelves in front of you and thousands of books. You could take a picture and you'd immediately know where the book you're looking for is.'"

theodp writes "Back in 1942, Chicago mail-order house Spiegel's looked to handwriting analysis to identify inconsistent, unreliable, poorly adjusted people. Ah, those were the days. TIME reports we are witnessing the death of handwriting, noting that Gen Y struggles with cursive and the group following them has even less of a need for good penmanship. And while the knee-jerk explanation is that computers are to blame for our increasingly illegible scrawl, literacy prof Steve Graham explains that kids haven't learned to write neatly because no one has forced them to. 'Writing is just not part of the national agenda anymore,' he says. So much for 100 Years of Handwriting Success!"

An opinion piece on Gamasutra discusses how, in spite of the fancy new motion control systems that have come to console gaming, the PC's keyboard and mouse setup is still unreplaceable for many titles and genres. Quoting: "With over 100 keys to choose from (back of the box quotation right there), the possibilities are near endless, if you start to think of shift and control functions altering the purpose of keys. It means that, when the developers start to make their game, they don't have to worry about the limitations of the interface, knowing that, if all else fails, they can always assign the compass to K, even if that's a bit of a stretch to all but the pianists. The keyboard is the friend of ambition, and ArmA 2 is the testament to that, in all its surrealist, broken glory. ... It's the same reason RTS games have found a home on the PC for so long, able to use the skills people accumulate moving around windows and clicking on icons to command troops and manipulate their battle lines. Developers taking advantage of what we already know to teach us something we don't is what gaming is all about."

CNETNate writes "The world's first 3D webcam not only takes anaglyphic images, but will let you have a stereoscopic 3D video chat over the Internet. It's the work of a unique camera called 'Minoru,' which has been tested and documented in a feature today. Be warned though: anaglyphic photography was clearly not invented to create comfortably-viewable videos."

LosManos writes "Which is the best programming mouse? Mandatory musts are wireless, and that it doesn't clog up like old mechanical mice. Present personal preferences are for: lots of buttons, since if I have moved my hand away from the keyboard I can at least do something more than move the pointer; sturdy feeling; not too light, so it doesn't move around by me accidentally looking at it."
