Sony Launches SDK For SmartEyeglass

Sony has rolled out an SDK (software development kit) for its SmartEyeglass head-mounted display, another step toward challenging Google Glass.

The glasses can connect to Android smartphones via Bluetooth and project green monochrome text or basic graphics across a field within the lenses.

Sony said it will begin sales of the eyewear to developers by March 31, the end of its fiscal year. They will be sold in Japan, the U.S. and some European countries.

The Developer Preview SDK includes an emulator, tutorials, sample code and design guidelines to make the most of the device’s hardware and sensors including an accelerometer, gyroscope and brightness sensor.

The glasses, which weigh 77 grams, are more than 85 percent transparent and include a camera that can shoot 3-megapixel images and VGA video.

Sony has emphasized that the glasses project images to a user’s natural line of sight, which differs from the Google Glass display set in a corner.

“Sony’s competitive edge lies in our achievement of a thin lens with high transparency thanks to our unique holographic light guide plate technology, which enables us to provide a bright field of vision,” a Sony spokeswoman wrote in an email.

“Furthermore, the screen size is large, and images and text are displayed from the front for both eyes (not only one eye) to facilitate easier viewing and prevent eye fatigue.”

The price for the glasses as well as availability of a consumer version are still to be decided, she added.

Bulky prototype versions of the glasses were shown at the IFA and CES electronics shows earlier this year.

Potential applications include displaying cooking instructions for chefs, running time for joggers and messages from friends.

Augmented reality-style functions are also possible, such as displaying information when a user looks at a certain bottle of wine, facial recognition or navigation information in an unfamiliar city.

Toshiba Develops Mobile Sensor

Toshiba has created a new image sensor for mobile phones and tablets that promises better image resolution for run-of-the-mill smartphones when it goes into mass production.

The T4KA7 is a 1/2.4-inch, 20-megapixel backside illuminated sensor with a 1.12 micrometer pixel size, which provides for a smaller sensor size overall.

The sensor allows for a lower module height of under 6 millimeters compared to the current 20-megapixel, 1.2-micrometer sensors, the company said.

“T4KA7 is the first 1.12-micrometer, 20-megapixel sensor on the market with a high frame rate of 22 fps at full resolution,” a Toshiba spokeswoman wrote in an email.

The frame rate is 1.8 times the speed of Toshiba’s previous 20-megapixel sensor, the T4K46.

When zooming digitally, the sensor provides crisper images compared to 13- and 16-megapixel sensors, which are resolutions widely adopted in recent smartphones, she added.

Announced earlier this year, Samsung’s camera-phone hybrid Galaxy K zoomhas a 20.7-megapixel image sensor that is supposed to perform well when taking photos in low-light settings.

Without a specific measurement for comparison, it’s hard to say whether the T4KA7 would do any better in low-light shooting situations than other sensors, the Toshiba spokeswoman said.

“We think we are providing top-class sensors in terms of pixel performance,” she added.

Toshiba is producing samples of its new sensors now, with mass production of up to half a million units per month to begin in November.

Higher-end smartphones already featuring 20-megapixel cameras include the Sony Xperia Z1, the Nokia Lumia 930 and 1520.

Announced last month, the Nokia Lumia 1020 sports a camera designed for photographers — it has a sensor with 41-megapixel resolution.

Can Plastic Replace Silicon?

Can plastic materials morph into computers? A research breakthrough recently published brings such a possibility closer to reality.

Researchers are looking at the possibility of making low-power, flexible and inexpensive computers out of plastic materials. Plastic is not normally a good conductive material. However, researchers said this week that they have solved a problem related to reading data.

The research, which involved converting electricity from magnetic film to optics so data could be read through plastic material, was conducted by researchers at the University of Iowa and New York University. A paper on the research was published in this week’s Nature Communications journal.

More research is needed before plastic computers become practical, acknowledged Michael Flatte, professor of physics and astronomy at the University of Iowa. Problems related to writing and processing data need to be solved before plastic computers can be commercially viable.

Plastic computers, however, could conceivably be used in smartphones, sensors, wearable products, small electronics or solar cells, Flatte said.

The computers would have basic processing, data gathering and transmission capabilities but won’t replace silicon used in the fastest computers today. However, the plastic material could be cheaper to produce as it wouldn’t require silicon fab plants, and possibly could supplement faster silicon components in mobile devices or sensors.

“The initial types of inexpensive computers envisioned are things like RFID, but with much more computing power and information storage, or distributed sensors,” Flatte said. One such implementation might be a large agricultural field with independent temperature sensors made from these devices, distributed at hundreds of places around the field, he said.

The research breakthrough this week is an important step in giving plastic computers the sensor-like ability to store data, locally process the information and report data back to a central computer.

Mobile phones, which demand more computing power than sensors, will require more advances because communication requires microwave emissions usually produced by higher-speed transistors than have been made with plastic.

It’s difficult for plastic to compete in the electronics area because silicon is such an effective technology, Flatte acknowledged. But there are applications where the flexibility of plastic could be advantageous, he said, raising the possibility of plastic computers being information processors in refrigerators or other common home electronics.

“This won’t be faster or smaller, but it will be cheaper and lower power, we hope,” Flatte said.

What Do Smaller Controllers Mean?

If you want a wearable Internet of Things, the electronics have to be as tiny and as energy efficient as possible. That’s why a new microcontroller by Freescale Semiconductor is noteworthy.

The company has produced the Kinetis KLO3 MCU, a 32-bit ARM system that is 15% smaller than its previous iteration but with a 10% power improvement.

Internet of Things is a buzzword for the trend toward network-connected sensors incorporated into devices that in the past were standalone appliances. These devices use sensors to capture things like temperatures in thermostats, pressure, accelerometers, gyroscopes and other types of MEMS sensors. A microcontroller unit gives intelligence and limited computational capability to these devices, but is not a general purpose processor. One of the roles of the microcontroller is to connect the data with more sophisticated computational power.

The Kinetis KLO3 runs a lightweight embedded operating system to connect the data to other devices, such as an app that uses a more general purpose processor.

Kathleen Jachimiak, product launch manager at Freescale, said the new microcontroller will “enable further miniaturization” in connected devices. This MCU is capable of having up to 32 KB of flash memory and 2 KB of RAM.

Consumers want devices that are light, small and smart. They also want to be able to store their information and send it to an application that’s either on a phone or a PC, Jachimiak said.

This microcontroller, at 1.6 x 2.0 mm, is smaller than the dimple on a golf ball, and uses a relatively new process in its manufacturing, called wafer level chip scale packaging. The process involves building the integrated package while the die is still part of a wafer. It’s a more efficient process and produces the smallest possible package, for a given die size.

Apple Hacked

A group of German hackers claimed to have successfully breached the iPhone fingerprint scanner on Sunday, just two days after Apple Inc debuted the technology that it promises will better protect devices from criminals and snoopers seeking access.

If the claim is verified, it will be embarrassing for Apple which is betting on the scanner to set its smartphone apart from new models of Samsung Electronics Co Ltd and others running the Android operating system of Google Inc.

Two prominent iPhone security experts told Reuters that they believed the German group, known as the Chaos Computing Club, or CCC, had succeeded in defeating Apple’s Touch ID, though they had not personally replicated the work.

One of them, Charlie Miller, co-author of the iOS Hacker’s Handbook, described the work as “a complete break” of Touch ID security. “It certainly opens up a new possibility for attackers.”

Apple representatives did not respond to requests for comment.

CCC, one the world’s largest and most respected hacking groups, posted a video on its website that appeared to show somebody accessing an iPhone 5S with a fabricated print. The site described how members of its biometrics team had cracked the new fingerprint reader, one of the few major high-tech features added to the latest version of the iPhone.

The group said they targeted Touch ID to knock down reports about its “marvels,” which suggested it would be difficult to crack.

“Fingerprints should not be used to secure anything. You leave them everywhere, and it is far too easy to make fake fingers out of lifted prints,” a hacker named Starbug was quoted as saying on the CCC’s site.

The group said it defeated Touch ID by photographing the fingerprint of an iPhone’s user, then printing it on to a transparent sheet, which it used to create a mold for a “fake finger.”

CCC said similar processes have been used to crack “the vast majority” of fingerprint sensors on the market.

“I think it’s legit,” said Dino Dai Zovi,” another co-author of the iOS Hacker’s Handbook. “The CCC doesn’t fool around or over-hype, especially when they are trying to make a political point.”

Touch ID, which was only introduced on the top-of-the-line iPhone 5S, lets users unlock their devices or make purchases on iTunes by simply pressing their finger on the home button. It uses a sapphire crystal sensor embedded in the button.

Data used for verification is encrypted and stored in a secure enclave of the phone’s A7 processor chip.

Two security experts who sponsored an impromptu competition offering cash and other prizes to the first hackers who cracked the iPhone said they had reviewed the information posted on the CCC website, but wanted more documentation.

“We are simply awaiting a full video documentation and walk through of the process that they have claimed,” said mobile security researcher Nick DePetrillo, who started the contest with another security expert, Robert Graham. “When they deliver that video we will review it.”

The two of them each put up $100 toward a prize for the contest winner, then set up a website inviting others to contribute. While the booty now includes more than $13,000 in cash, it was not clear that the CCC would receive the full payout, even if DePetrillo and Graham declared them winners.

Toshiba To Offer A 20-megapixel Image Chip

Toshiba is gearing up for to offer a 20-megapixel image sensor for digital cameras that it says will be the highest resolution of its kind.

The Tokyo-based firm said the new chips will be able to support capturing 30 frames per second at full resolution. They will also be able to shoot video at 60 frames per second at 1080P or 100 frames at 720P.

Toshiba said it will begin shipping samples of the new CMOS chips in January, with mass production to begin in August of 300,000 units monthly. Toshiba is best known in components for its NAND flash memory, which it develops with partner SanDisk, but is also a major manufacturer of LSI and other semiconductors.

Digital point-and-shoot cameras are steadily falling in price, squeezed between brutal competition among manufacturers and the increasing threat of smartphones and mobile devices. While the number of pixels a camera can capture is not always a direct measure of the overall quality of its images, it is a key selling point to consumers.

The image resolution of top-end smartphones now often meets or exceed that of digital cameras. The Nokia 808 PureView launched earlier this year has a 41-megapixel image sensor.

The Japanese manufacturer said it has increased the amount of information pixels in the new chip can store compared to its previous generation of CMOS, producing better overall images. It has also reduces the size of pixels – the new 20-megapixel version has individual pixels that measure 1.2 micrometers, down from 1.34 micrometers in its 16-megapixel product.
