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.

NTT Communications (NTT Com) has announced plans to begin testing its latest aroma-emitting digital sign technology, called “Kaoru Digital Signage,” in Tokyo. The tests, which will take place outside the Kirin City Beer Hall in the underground Yaesu Shopping Mall (JR Tokyo station) from October 21 to the end of December, will involve internet-controlled signs that display electronic imagery of beer while emitting aromas such as lemon and orange. The researchers aim to study the sign’s effectiveness in drawing passersby into the restaurant.

Billed as the world’s first advertising sign system capable of emitting multiple aromas while displaying electronic images, the signs combine NTT’s Spot Media digital signage service (currently used in marketing and customer service applications at banks, hospitals, public offices and retail stores) with its Kaori Tsushin online fragrance communication service. Kaori Tsushin, which gives users web-based control over aroma-emitting devices, is already in use at retail stores and cafes, where it is reportedly helping to improve on-site customer satisfaction.

NTT’s new sign system consists of a 30 x 50 x 15 centimeter (12 x 20 x 6 inch) aroma diffuser, a 19-inch display and an NTT Spot Media content receiver, which are used to deliver aroma and display images of beer (and live shots from inside the restaurant) based on instructions received via a web connection. In the tests, the sign’s smell will change according to the time of day, dispersing appetizing orange and lemon aromas at lunchtime, and releasing a more relaxing “woody” aroma at night.

The aroma diffuser contains three 450-milliliter bottles of aroma oil. When the “recipe” — which determines the type and strength of smell — is received via the web, the device releases a vapor created by blasting the oil with a series of ultrasonic waves. With the ability to deliver fragrances across a 500 square meter (5,400 square feet) area, the new aroma diffuser is a great deal more powerful than NTT’s Aromageur, which was developed for personal use in spaces the size of a small bedroom.

The scheduled testing follows a spate of aroma-related experiments conducted by NTT earlier this year. On Valentine’s Day, NTT researchers conducted an experiment with vanilla fragrance in an office lobby. When vanilla fragrance was periodically released near free chocolate (labeled with a “Please Take One” sign) placed on a reception counter, the researchers found that passersby were nearly twice as likely to take a chocolate. In other experiments conducted at Tokyo-area bookstores from May to September, relaxing orange and lavender aromas were found to boost monthly sales by nearly 5%.

On June 20, NTT Docomo and am/pm Japan announced plans to begin equipping convenience stores with cellphone recycling bins, making it easier for people to recycle their unwanted handsets.

Since 1998, Japan’s wireless providers have been recycling unwanted phones in their own stores for customers who switch models or cancel their contracts. In recent years, however, more and more customers are waiting to recycle their old handsets, as phones have grown more sophisticated and hold greater amounts of important data that users need to access after switching models. Most users eventually decide to dispose of their phones, though, so NTT is hoping they will make use of these recycling bins, which will initially be set up at eight convenience stores in central Tokyo.

The recycling bins, which are designed to prevent people from stealing the cellphones inside, are open to unwanted handsets of all makes and models.

In 2005, NTT harvested 37,993 kg (42 tons) of copper and 145 kg (320 pounds) of gold from old phones.

Researchers at NTT Comware have just made virtual reality a little more real. On June 20, the company unveiled a 3D display system that reproduces the physical feel of three-dimensional video by means of an actuator glove worn on the hand, allowing viewers to literally reach out and touch the person or object on the screen.

The so-called “Tangible-3D” prototype system is built around an improved version of NTT’s 3D display — originally developed in 2005 — which displays 3D images without requiring special glasses. The system relies on a pair of cameras that capture and process data about the position, shape and size of objects as they are filmed. As the two video images are combined into a 3D image that is displayed on the screen at the receiving end, the data is relayed to the glove, whose array of actuators translate it into a tactile impression the user can feel. The glove operates in real-time along with the 3D video, so the user can “feel” the on-screen image as it moves.

For now, the Tangible-3D system only works in one direction, but NTT Comware is developing a two-way system that allows tactile impressions to be transmitted back and forth between multiple users. The company is also working to improve the 3D screen, which only appears three-dimensional from a particular viewing angle.

While the possibilities for this technology are endless, NTT Comware suggests it could be put to use in museum exhibits that would allow visitors to handle items on display that are ordinarily off-limits. The company also says this technology could be put to use in classrooms, where it would allow students to touch objects located very far away.

NTT Comware will exhibit the Tangible-3D system at the Industrial Virtual Reality Expo being held at Tokyo Big Sight from June 27 to 29.

NTT-Neomeit, an NTT subisidiary, has unveiled plans for a convenient and inexpensive service that allows users to remotely control home devices from their cellphones. Scheduled for launch in September, the “U-Consento” service is designed to be compatible with a wide range of existing home appliances, so users do not need to purchase new devices or perform extensive home rewiring.

To control devices, users access a web page via cellphone and select the desired operations. The commands are then sent via the web to a wireless router in the home, which relays signals to an infrared transmitter and remote control power switches. The infrared transmitter, which operates like a universal remote, relays those signals to remote controllable devices such as home A/V equipment. Easy-to-install remote control switches connected to power outlets allow users to turn on and off the power to lamps and other devices not pre-equipped with remote control.

In addition to being able to control the room temperature, blast the stereo and program the video recorder — all while outside the home — users can also check the current operating status of each device and view records of how each device has been used. According to NTT-Neomeit, this ability to monitor device usage provides a convenient way for users to keep tabs on the activity of their elderly parents from afar.

NTT-Neomeit plans to rent the home remote control system starting at around 500 yen ($4) per month, and service will initially be limited to NTT broadband subscribers in western Japan. Pilot testing will be conducted in the Kansai area from May to August.

The NTT Group has unveiled technology that analyzes the interest level of TV viewers and web surfers by monitoring their eye movement, pupil size and blinking.

Improving on conventional eye-tracking systems that provide an understanding of where viewers cast their gaze, this new computer-operated system features cameras that monitor and analyze unconscious physiological reactions to interesting viewing material — namely, enlarged pupils and changes in the rate of blinking.

The technology, which became commercially available on March 14, was developed by NTT Learning Systems (NTTLS) and the Visual Interactive Sensitivity Research Institute (VIS), both of which are involved in visual content creation. NTTLS says the technology can be used in conjunction with driver safety training videos, and negotiations with a major automaker are now underway.

NTTLS claims the system appeals to a wide range of potential users, including those involved in TV commercial advertising and web content creation. Television audience ratings alone do not provide producers a clear picture of the level of interest in commercials, and web traffic stats do not show which parts of a web page visitors find interesting. With this system, however, producers can get a more accurate understanding of what the audience is looking at and how interesting they find it.

Judging from the large size (and presumably high cost) of the device that sits between the viewer and the monitor, though, the system is clearly designed for use in the laboratory. But it’s just a matter of time before this is standard computer monitor/TV screen equipment and producers keep one eye on the real-time audience pupil data while they develop and deliver content.

NTT is developing a device that provides advance warning of earthquakes seconds before they strike by relying on data from a nationwide system of seismometers put in place by the Japan Meteorological Agency. The sensors detect an earthquake’s primary waves (”P-waves”), which travel more quickly and are much weaker than the lower-velocity secondary waves (”S-waves”) that cause the major damage associated with earthquakes.

When the sensors detect P-waves, data about the timing and strength of the coming S-waves is instantly delivered to the earthquake alarms via NTT’s fiber optic network, notifying the users in their homes before the S-waves strike. The time difference between the arrival of P-waves and S-waves depends on the distance from the epicenter, so locations farther from the epicenter can receive warnings much more in advance than those near the epicenter. Unfortunately, people located directly above the epicenter, where the earthquake is at its strongest, are unlikely to receive any advance warning at all.

The TV commercial for the device (as well as the extended web version, now on YouTube) shows a mildly touching dramatization of the device at work.

The commercial focuses on a female college student who is majoring in home economics and living at home with her parents. When home alone, the girl spends most of her free time in the kitchen honing her cooking skills by preparing dishes like goya kinoko champuru, an Okinawan stir-fry made with bitter gourd, mushroom and eggs. The kitchen is equipped with an NTT earthquake alarm.

The first time the earthquake alarm sounds, the girl goes into a mild panic, squandering her 20-second warning by wondering where to set the dish she is holding. She finally crawls under the dining table and all is well.

The next time an earthquake comes, she is prepared. The alarm sounds and the mechanical voice informs her that a magnitude 3 earthquake will strike in 20 seconds. As the countdown begins, she calmly turns off the stove, opens the patio doors, and crawls under the table. The voice instructs her to protect herself from physical harm until the shaking stops, advising her not to run outside in a panic. The voice then instructs her to make sure the gas is turned off and evacuate to a safe place once the quake has passed. Finally, the voice instructs her to pay attention to the information provided by the mass media and the local authorities, again reminding her to remain calm.

Later, the girl’s mother calls to check on her. Having cooked a great deal of food, the girl tells her mother to come home hungry. Later they will feast.

Luckily for all, the earthquake was only a magnitude 3 affair, unlike the monster that struck Kobe back in 1995.

I have fortunately never seen the need to duck and cover during an earthquake and I don’t know how well I would fit under my dining table, but nonetheless it would be nice to have a 20-second warning before the Big One hits.

NTT Docomo’s new FOMA N701i ECO, the world’s first cellphone to incorporate parts made from plant-based plastic, is scheduled for release this spring.

In June 2005, NTT and NEC worked together to develop prototypes, which were used at the Aichi World Expo. The plant-based plastic is formed from polyactide, which is derived from corn. Kenaf (a fibrous plant) fiber is used as a reinforcing agent, improving heat resistance and strength. About 75% of the phone’s surface area will use the plant-based plastic, reducing carbon dioxide emissions during manufacturing by 50%.

NTT will target environmentally conscious females with the cellphones, which will be pink. The price is expected to be about the same as the N701i. NTT will devote 1% of the purchasers’ monthly telephone bills toward environmental conservation activities, such as its Docomo Forest campaign.
