Intelligent road system to boost traffic safety

17 Aug 2006

Driving Safety Support System

Japan's National Police Agency is moving forward with plans to introduce a road safety system that alerts drivers to potential hazards through audio and visual notifications on in-vehicle navigation systems. With testing scheduled to begin in Tokyo this year, the system is expected to be rolled out in 2008 after the test results are verified.

The system, developed by the Universal Traffic Management Society of Japan (UTMS), is known as the Driving Safety Support System (DSSS). The system relies on networks of two-way communication devices called infrared beacons installed at a height of 5.5 meters above roadways, particularly in accident-prone areas. These infrared beacons detect the presence of vehicles and pedestrians in hard-to-see locations and communicate this information to drivers through their in-vehicle navigation systems.

As many as 20 different subsystems, each designed to prevent a specific type of accident (rear-end collisions, head-on collisions, right-turn collisions, etc.), are being studied. Of these subsystems, 5 are expected to be rolled out in 2008 and are being tested in Tokyo -- including one that alerts drivers to the presence of pedestrians when turning left through intersections, one for highways that provides information about merging traffic, and one that provides information about traffic snarl-ups to prevent rear-end collisions.

DSSS is similar to the Vehicle Information and Communication System (VICS), an existing system that also relies on infrared beacons to communicate traffic information to in-vehicle navigation systems, but only about 10% of all vehicles in Tokyo make use of this system. Future studies will focus on developing ways to popularize this type of system.

The tests in Tokyo are designed to provide a detailed investigation of the effectiveness and impact on the safety of ordinary drivers. When experimental testing of the 5 systems was carried out in Toyota City in Aichi prefecture from 2002 to 2004, more than 80% of users thought they were effective.

Video: Tokyo nuclear attack

06 Aug 2006

This short video of Tokyo under nuclear attack was pieced together using footage from a 1984 NHK documentary about nuclear war, which featured a high-tech (at the time) simulation showing the impact an 8-megaton bomb explosion would have on the city. The soundtrack is Sun Ra's "Nuclear War" (1982) as performed by Yo La Tengo (2002). Peace.

JR passengers to generate electricity at train stations

01 Aug 2006

Ticket gate electric generatorThe East Japan Railway Company (JR-East), as part of research aimed at developing more environmentally friendly train stations, is testing an experimental system that produces electricity as people pass through ticket gates. JR claims that this sort of human-powered electricity generation system may provide a portion of the electricity consumed at train stations in the future.

The ticket gate electricity generation system relies on a series of piezo elements embedded in the floor under the ticket gates, which generate electricity from the pressure and vibration they receive as people step on them. When combined with high-efficiency storage systems, the ticket gate generators can serve as a clean source of supplementary power for the train stations. Busy train stations (and those with large numbers of passengers willing to bounce heavily through the gates) will be able to accumulate a relatively large amount of electricity.

JR-East, who worked with Keio University to develop the system, claims that in addition to being put to use as an independent power supply that does not require hardwiring, the system can also be used as a way of measuring the traffic flow through ticket gates.

The system is being tested at the JR-East head office in Shibuya, where it is installed at the entrance to the reception area on the 4th floor. As visitors pass through the gate, a lamp lights up, signifying that electricity has been produced. Testing of the system will continue until August 11.

Ghost scroll collection at Zenshoan temple

01 Aug 2006

Ghost scroll at Zensho-an templeEvery August, Zenshoan temple in Tokyo opens the doors to its Yurei-ga Gallery, a private collection of Edo-period ghost scrolls. The 50 silk paintings, most of which date back 150 to 200 years, depict a variety of apparitions from the forlorn to the ghastly.

The scrolls were collected by Sanyu-tei Encho, a famous storyteller (rakugo artist) during the Edo era who studied at Zenshoan. Encho is said to have collected the scrolls as a source of inspiration for the ghostly tales he loved to tell in summer.

Telling ghost stories has long been a popular summer pastime in Japan, and many people believe that chilling tales have the power to take the edge off the dreadful heat. Stories of shadowy souls also make a nice, macabre complement to all the August rituals (bon festivals, memorial ceremonies, grave cleaning, etc.) performed to welcome the spirits of departed ancestors as they return en masse to the earthly world.

The ghost scrolls are on display from August 1 to 31, from 10 AM to 5 PM. Zenshoan temple is located a five-minute walk from Sendagi station (in Taito ward) on the Chiyoda subway line. The entrance fee is 300 yen.

If you can't make it to the temple, check out an online version of the gallery at the link below.

Giant video screen constructed at Tokyo-area horse track

25 Jul 2006

World's largest display

Mitsubishi Electric has completed construction of the world's largest high-definition video screen at a horse track in Tokyo. The screen employs Mitsubishi's Aurora Vision LED technology and measures 11.2 meters (37 feet) x 66.4 meters (218 feet), giving it a surface area of 744 square meters (8,000+ square feet), or the equivalent of 3 tennis courts. Mitsubishi manufactured the screen for the Japan Racing Association (JRA) at its Nagasaki factory in the town of Togitsu, Nagasaki prefecture. The screen was divided into 35 pieces for delivery to the Tokyo Racecourse in Fuchu, Tokyo.

The bright, high-definition display is 3 times larger than what was previously installed at the horse track, and the screen's three sections allow the audience to take in the action at other tracks. Total cost is reported to be 3.2 billion yen (US$28 million).

Face to face with high-tech medical devices

13 Jul 2006

The International Modern Hospital Show 2006 is being held from July 12 to 14 in Tokyo (Tokyo Big Sight), where nearly 400 companies have gathered to showcase the latest in healthcare-related technology. The theme of the show is "Reliable Health, Medical Treatment, and Care -- Aiming for High Quality Service," a theme whose success evidently depends on high technology. Below are photos (via Impress Watch) and explanations of a few of the devices appearing at the show. Despite appearances, these fellows are here to help.

The first photo shows a patient simulator developed by IMI Corporation and Paramount Bed Co., Ltd., a system consisting of a monitor connected to a sensor-laden mannequin whose physiology changes realistically according to the treatment it receives. Great for training future medical professionals. Great for your haunted house, too.

The next photo shows a transnasal endoscope developed by FUJIFILM Medical Co., Ltd. and Fujinon Toshiba ES Systems Co., Ltd. Surveys show that 90% of patients who have experienced endoscopy think it is more comfortable to enter through the nose (as opposed to through the mouth or anus). I hope the expression on this guy's face is no indication of his comfort level.

The next photo shows Muu Socia 3.0 (left), a cute cyclopean teardrop-shaped "communication support" robot developed by ATR and Systec Akazawa. The robot is designed to serve as a social mediator that livens up the communication between care giver and care recipient. Muu Socia has voice recognition, voice synthesis, speech processing and face recognition capabilities. And it starts bouncing around when something obstructs its view (watch the 5-second video (WMV)).

Pictured on the right is a home appliance control robot developed by RayTron Co., Ltd. Voice recognition capabilities allow patients to operate their home appliances by remote control. It looks sort of like an owl.

Rainy season brings glow-in-the-dark mushrooms

24 May 2006

Glowing mushroomsWith the arrival of Japan's rainy season, a mysterious type of green, glow-in-the-dark mushroom begins to sprout in Wakayama prefecture. The Mycena lux-coeli mushrooms, known locally as shii no tomobishi-dake (literally, "chinquapin glow mushrooms"), sprout from fallen chinquapin trees. As they grow, a chemical reaction involving luciferin (a light-emitting pigment contained within the mushrooms) occurs, causing them to glow a ghostly green.

The luminescent mushrooms were long believed to be indigenous solely to Tokyo's Hachijojima Island after they were discovered there in the early 1950s. In 1995, however, mycologists found the fungus growing wild in coastal areas of the southern Kii peninsula, as well as in Kyushu and other areas.

The mushrooms thrive in humid environments, popping up during Japan's rainy season, which typically lasts from the end of May to July. The caps can grow to as large as 2 cm (about 1 inch) in diameter, but because the mushrooms are prone to dehydration, they only have a few days to live once the rain stops.

Chatty shows face at local anime fair

25 Mar 2006

ChattyChatty, a talking mannequin with a human face, is on display at the Tokyo International Anime Fair 2006 (at Tokyo Big Sight through March 26).

Developed by Ishikawa Optics & Art Corporation, Chatty has a face that is brought to life by means of a video projector inside its head. A video image of an actual human face (or the face of a computer-generated character, if you prefer) is projected onto the inner surface of the mannequin's face, which serves as a three-dimensional video screen. Audio synced with Chatty's video lip movements gives the face an astonishingly realistic look.

Chatty's presence at the anime fair brings Ishikawa one step closer toward realizing its dream, which is to see the technology behind Chatty's face be put to use in speech-capable historical figures for museum exhibits, theme park guides, or human-faced androids.

Akihabara maids want your blood

24 Mar 2006

Akiba maid gives hand massage to blood donorAs the number of willing blood donors in Japan continues to decline, the Japanese Red Cross is stepping up efforts to reverse the trend by offering a unique range of services at blood donation sites.

These services include hand massages by Akihabara "maids," hair/scalp health checks, and palm readings. The Japanese Red Cross has organized the services in part to increase the number of repeat donors, considered critical in combating the declining number of blood donors resulting from the aging of the population.

At the Akiba Blood Donation Room near JR Akihabara station, a young woman wearing a white apron over a dark green one-piece dress greets a donor as he enters. "Welcome back, my lord," she says. After the man is finished with his blood draw, she gives him a 10-minute hand massage. The maid, who is an employee at a local foot care salon, was enlisted by the Red Cross in its attempt to capitalize on the local "maid cafe" boom. The Akiba Blood Donation Room is offering this service until the end of March.

A spokesman for the Akiba Blood Donation Room says there were initial concerns about whether the service went too far. But in an attempt to boost the number of weekday donors -- whose numbers are less than half those of their weekend counterparts -- they decided to go ahead and offer the special service to the first 10 people on Mondays, Wednesdays and Thursdays.

Some donors are surprised to encounter a young woman dressed as a maid. But one donor, after giving blood, remarked, "It?s very 'Akiba.' It's fun.?

Several years ago, the Shinjuku station (east exit) blood donation site began offering manicures and hair care advice provided by specialists from the Japan Hair Science Association. Now, those services are firmly established. After the Yurakucho blood donation site began offering tarot card and palm readings last year, many repeat donors began scheduling their visits to coincide with days that fortune-telling services were offered.

Fun aside, the Japanese Red Cross sees the declining number of blood donors as a serious problem. In 1993, 7.2 million people gave blood in Japan, compared to 5.6 million in 2003. Donors under 30 years of age, who made up 47% of the total in 1993, fell to 35% of the total in 2003.

Over the next five years, the Red Cross hopes to increase the number of repeat donors (who give more than once a year) from the current number of 930,000 to 1.2 million. They will begin offering other services to people who register for membership on the "repeater" homepage, such as free health consultations from doctors and health counselors at each blood center.

The demand for blood fluctuates with the occurrence of major disasters and accidents. By boosting the number of weekday donors and repeaters, the Red Cross hopes to secure a stable supply of safe blood.
