SoftBank Mobile testing smart movie posters

03 Sep 2008

Wall-E --

Japan's first field test of "smart posters" using Near Field Communication (NFC) -- a short-range high-frequency wireless communication technology that lets users view digital content simply by holding their compatible cellphones near the posters -- is being conducted at a Chiba-area shopping mall, it was announced on September 2.

Major phone operator SoftBank Mobile, along with NTT Data, Hitachi and Dutch smart chip maker Gemalto, are testing the technology with WALL-E and Tinker Bell movie posters embedded with NFC tags.

Throughout October, selected test participants will be able to receive and view digital content such as movie stills and trailers simply by holding their NFC-compatible phones (containing NFC-USIM cards) next to the smart posters. Along with the digital content, users also receive an access code that, when transferred to a compatible Hitachi HDTV at home, allows them to view a WALL-E trailer in high definition (via Hitachi's content distribution service).

The tests, which are designed to help the companies evaluate the effectiveness and potential of NFC smart posters as a promotional medium, could be a sign of things to come in the field of poster advertising. Should NFC smart posters become cheap and easy to produce, they have the potential to replace the ubiquitous QR (2D) code that commonly appears in Japanese advertising posters. NFC is seen as more convenient than QR code because the user does not have to scan a code and visit a separate website to view the data. Instead, digital content can be accessed directly with a simple swipe of the phone.

Yen portraits fool age-verification cameras

08 Jul 2008

Hideyo Noguchi & Yukichi Fukuzawa --

Do these fellows look old enough to smoke? Yes indeed, say Japan's cigarette vending machines that use face-recognition technology to determine the age of the purchaser.

Just two weeks after a major sports paper reported that magazine photos could be used to fool vending machine age-verification cameras, an even more surprising flaw has come to light. The portraits of Hideyo Noguchi and Yukichi Fukuzawa printed on the 1,000-yen and 10,000-yen bills can be used to trick the high-tech machines, according to a new report on the Sankei Shimbun website.

On July 1 -- the day that Japan's cigarette vending machine age-verification system was rolled out nationwide -- Sankei reporters in Tokyo went out in search of machines equipped with age-verification cameras. They found that these machines treated them as adults and allowed them to purchase cigarettes when they showed the portrait of Yukichi Fukuzawa (the renaissance man and Keio University founder who appears on the 10,000-yen note) to the vending machine's camera-embedded mirror. The machines also reportedly sold cigarettes to the portrait of Hideyo Noguchi (the notable bacteriologist who discoveredcontributed to the understanding of syphilis), which appears on the 1,000-yen note.

Once the machines approved the sale, the reporters then used the same money to pay for the purchase, making this all-in-one technique even more convenient than the recently discovered magazine photo trick.

Ironically, news of this latest discovery comes just days after the Finance Ministry officially approved the use of face-recognition technology to determine the age of vending machine users.

Sankei contacted the Finance Ministry's Tobacco and Salt Industries Office about the flaw they found. A surprised official responded by saying, "This is the first we've heard of it. It's a big problem if it's true."

The official said he would immediately notify Fujitaka, the vending machine manufacturer who developed the age-verification camera system. Fujitaka is reportedly in the process of upgrading its face-recognition technology so that it can more effectively distinguish photographs from real people.

Of Japan's more than 500,000 cigarette vending machines, around 4,800 (less than 1%) are equipped with age-verification cameras. The rest are outfitted with readers that check Taspo age-verification cards, which are available to anyone of legal age who applies (though they have yet to become widespread). The vending machines that use age-verification cameras allow people to purchase cigarettes without a Taspo card, as long as they look older than 20 years of age.

Magazine photos fool age-verification cameras

Face-recognition cigarette vending machine --

With the full-scale rollout of Japan's cigarette vending machine age-verification system just around the corner, a Sankei Sports news reporter has confirmed the existence of a minor flaw: magazine photos can be used to fool the age-verification cameras on some machines.

When the reporter went to check out the new age-verifying machines after they were introduced in the Osaka area in June, he soon discovered that the machines equipped with face-recognition cameras would let him buy cigarettes when he held up a 15-centimeter (6-in) wide magazine photo of a man who looked to be in his 50s.

The reporter also went to Kobe, where different face recognition hardware is being used. There, he bought cigarettes using an 8-centimeter (3-in) wide magazine photo of a female celebrity in her 30s. He also reportedly tried to use a 3-centimeter (1-in) wide photo, but the machines rejected it.

Taspo card -- As part of the age-verification system, most of Japan's 570,000 cigarette vending machines are being outfitted with RFID readers that check the purchaser's Taspo age-verification card. Smokers without a Taspo card can now either buy their cigarettes in person over the counter or use one of 4,000 special machines equipped with face-recognition systems (these machines do not require Taspo cards). More face-recognition machines are on the way, according to vending machine manufacturer Fujitaka, who developed the face-recognition hardware.

The face-recognition machines rely on cameras that scan the purchaser's face for wrinkles, sagging skin and other signs of age. Facial characteristics are compared with a database of more than 100,000 people, and if the purchaser is thought to be well over 20 years old (the legal age), the sale is approved. If the purchaser looks too young, they are asked to prove their age by inserting a driver's license. According to Fujitaka, the machines are 90% accurate.

Fujitaka admits that people may, on occasion, be able to fool the age-verification cameras with photographs -- but only for the time being. The company is now working on a more advanced system that will make sure each face belongs to a real human, but they are unable to say when these new machines will be put into place.

Kage Roi idea acceleration system

26 Jun 2008

Kage Roi -- IT company Kayac has teamed up with researchers from Keio University to develop a high-tech brainstorming room that listens to its inhabitants and feeds them a barrage of related data and images in order to boost creativity and fuel the imagination.

The system -- called "Kage Roi" -- relies on a speech-recognition capable computer that monitors the brainstorming session via microphone, identifies keywords, and automatically crawls the web in search of related information and images. A ceiling-mounted projector then casts the retrieved data and imagery onto dark, human-shaped shadows on the table during the course of the meeting. The brainstormers can free-associate on the projected data, use it as a tool for discussion, or rely on it for helpful cues if ideas are running short.

Kage Roi also features an ambient, multi-colored LED lighting system designed to stimulate creativity by altering the mood of the room. The "half-day course" setting, for example, simulates the rising and setting of the sun over the course of a 2-hour brainstorming session, helping to create a gradual mood shift as the meeting progresses.

Kayac developed Kage Roi in cooperation with the Keio University Inakage Lab (imgl), whose research focuses on next-generation digital communication and entertainment. The system was installed in a meeting room at Kayac headquarters last month, and the company plans to begin field-testing it soon.

Kayac hopes to develop a practical version of the system in the near future, and they are considering marketing it to companies in the content creation industry.

Robot teddy bear car navigation system

04 Jun 2008

Robot teddy bear car navigation system -- On June 3, engineers at iXs Research Corporation unveiled a robotic teddy bear designed to work as a talking car navigation system. The prototype robot stands 30 centimeters (1 ft) tall and has 6 joints in its arms and neck, which it uses to make gestures while providing spoken directions.

The robot bear is also equipped with functions to improve auto safety, such as an alcohol detection sensor embedded in its neck. If it smells booze, the robot confronts the driver, saying, "You haven't been drinking, have you?" Other sensors detect reckless driving, so if the driver suddenly accelerates or slams on the brakes, the robot says, "Watch out!"

As a bonus feature, the robot bear provides information about nearby landmarks when you stroke its head.

The company hopes to make the robot commercially available next year. "We want to make it more compact," says CEO Fuminori Yamasaki, "and we'd like to offer a variety of shapes, including other characters and a plain mechanical version."

Fujitsu has patented the idea of merging car navigation systems with dolls, but it has granted iXs Research Corporation permission to use the patent through a Kawasaki-area project encouraging major corporations to share intellectual property rights with small-to-medium-sized companies.

NTT Firmo transmits data through skin

24 Apr 2008

RedTacton human area network -- NTT has begun selling a device that transmits data across the surface of the human body and lets users communicate with electronic devices simply by touching them, the company announced on April 23.

The new product, called "Firmo," consists of a card-sized transmitter carried in the user's pocket. The card converts stored data into a weak AC electric field that extends across the body, and when the user touches a device or object embedded with a compatible receiver, the electric field is converted back into a data signal that can be read by the device. For now, Firmo transfers data at 230kbps, but NTT is reportedly working on a low-cost 10Mbps version that can handle audio/video data transfers.

Firmo is based on NTT's RedTacton human area network (HAN) technology, which is designed to allow convenient human-machine data exchange through natural physical contact -- even through clothing, gloves and shoes.

NTT initially hopes this human area network technology will appeal to organizations looking to boost convenience and security in the office. Obvious applications include secure entrances and keyless cabinets that recognize employees when they touch the door handle (thus bypassing the need for card-swipers and keys), or secure printers that operate only when you touch them.

For now, a set of 5 card transmitters and 1 receiver goes for around 800,000 yen ($8,000), but NTT expects the price to come down when mass production begins.

Japan’s cyborg research enters the skull

17 Apr 2008

Mind-controlled robot arm -- Researchers at Osaka University are stepping up efforts to develop robotic body parts controlled by thought, by placing electrode sheets directly on the surface of the brain. Led by Osaka University Medical School neurosurgery professor Toshiki Yoshimine, the research marks Japan's first foray into invasive (i.e. requiring open-skull surgery) brain-machine interface research on human test subjects. The aim of the research is to develop real-time mind-controlled robotic limbs for the disabled, according to an announcement made at an April 16 symposium in Aichi prefecture.

Although brain waves can be measured from outside the scalp, a stronger, more accurate signal can be obtained by placing sensors directly on the brain -- but that requires open-skull surgery, making it more difficult to recruit volunteer test subjects.

The researchers, who have filed a license application with the Osaka University Hospital ethics board, are working to enlist willing subjects already scheduled to have brain electrodes implanted for the purpose of monitoring epilepsy or other conditions. The procedure, which does not involve puncturing the cortex, places an electrode sheet at the central sulcus, a fold across the center of the brain near the primary motor cortex (which is responsible for planning and executing movements).

To date, the researchers have worked with four test subjects to record brain wave activity generated as they move their arms, elbows and fingers. Working with Advanced Telecommunications Research Institute International (ATR), the researchers have developed a method for analyzing the brain waves to determine the subject's intended activity to an accuracy of greater than 80%. The next step is to use the data to control robot arms developed by the University of Tokyo's Department of Precision Engineering.

ApriPoko robot learns to work the remote

25 Mar 2008

ApriPoco --

Researchers at Toshiba have developed a talking robot that functions as a voice-operated universal remote control for multiple home appliances. The 2.3 kilogram (5 lb), 21 x 27 centimeter (8 x 11 in) prototype robot, named ApriPoko, learns how to operate various remote controls by watching and asking questions. ApriPoko sits in the living room and waits for you to use a remote control. When its sensors detect infrared rays emitted by a remote, the robot speaks up: "What did you just do?" it asks. Tell ApriPoko what you did ("I turned on the stereo" or "I changed to channel 321," for example), and it commits the details to memory. Then, next time you want to turn on the stereo or change the channel, simply tell ApriPoko and it transmits the appropriate IR signal directly to the device. The prototype robot is still in the development and testing phase, but Toshiba hopes to have a viable product soon.

Cyber Goggles: High-tech memory aid

04 Mar 2008

Smart goggles --

Researchers at the University of Tokyo have developed a smart video goggle system that records everything the wearer looks at, recognizes and assigns names to objects that appear in the video, and creates an easily searchable database of the recorded footage. Designed to function as a high-tech memory aid, these "Cyber Goggles" promise to make the act of losing your keys a thing of the past, according to head researcher professor Tatsuya Harada.

Cyber Goggles are equipped with a compact camera that feeds video to a computer worn on the user's back. The computer records the footage and relies on ultrahigh-speed image recognition processing software to analyze, name and file the objects that appear in the video. Later, when the user types in a keyword to search for a particular item, the corresponding video plays on a tiny LCD screen attached to the right-side lens, helping the user remember the location of the item in question.

In a demonstration at the University of Tokyo last week, 60 everyday items -- including a potted begonia, CD, hammer and cellphone -- were programmed into the Cyber Goggle memory. As the demonstrator walked around the room viewing and recording the various objects, the names of the items appeared on the goggle screen. The demonstrator was then able to do a search for the various items and retrieve the corresponding video.

In addition to functioning as a memory aid for the elderly, Cyber Goggles have a number of other potential uses, says professor Harada. For example, the image recognition processing technology can be used to sift through enormous amounts of video in search of specific images. It might also help in the development of robots with human-like abilities, he says.
