U-Tsu-Shi-O-Mi Virtual Humanoid --

U-Tsu-Shi-O-Mi is an interactive "mixed reality" humanoid robot that appears as a computer-animated character when viewed through a special head-mounted display. A virtual 3D avatar that moves in sync with the robot's actions is mapped onto the machine's green cloth skin (the skin functions as a green screen), and the sensor-equipped head-mounted display tracks the angle and position of the viewer's head and constantly adjusts the angle at which the avatar is displayed. The result is an interactive virtual 3D character with a physical body that the viewer can literally reach out and touch.

U-Tsu-Shi-O-Mi Virtual Humanoid --

Researcher Michihiko Shoji, formerly of NTT DoCoMo, helped create U-Tsu-Shi-O-Mi as a tool for enhancing virtual reality simulations. He is now employed at the Yokohama National University Venture Business Laboratory, where he continues to work on improving the virtual humanoid. The system, which currently requires a lot of bulky and expensive equipment to run, will likely see its first real-world applications in arcade-style video games. However, Shoji also sees a potential market for personal virtual humanoids, and is looking at ways to reduce the size and cost to make it suitable for general household use.

Here is a video of U-Tsu-Shi-O-Mi.

The virtual humanoid will be on display at ASIAGRAPH 2007 in Akihabara (Tokyo) from October 12 to 14.

Brain-computer interface for Second Life

12 Oct 2007

Brain-computer interface controls Second Life avatar --

While recent developments in brain-computer interface (BCI) technology have given humans the power to mentally control computers, nobody has used the technology in conjunction with the Second Life online virtual world -- until now.

A research team led by professor Jun'ichi Ushiba of the Keio University Biomedical Engineering Laboratory has developed a BCI system that lets the user walk an avatar through the streets of Second Life while relying solely on the power of thought. To control the avatar on screen, the user simply thinks about moving various body parts -- the avatar walks forward when the user thinks about moving his/her own feet, and it turns right and left when the user imagines moving his/her right and left arms.

The system consists of a headpiece equipped with electrodes that monitor activity in three areas of the motor cortex (the region of the brain involved in controlling the movement of the arms and legs). An EEG machine reads and graphs the data and relays it to the BCI, where a brain wave analysis algorithm interprets the user's imagined movements. A keyboard emulator then converts this data into a signal and relays it to Second Life, causing the on-screen avatar to move. In this way, the user can exercise real-time control over the avatar in the 3D virtual world without moving a muscle.

Future plans are to improve the BCI so that users can make Second Life avatars perform more complex movements and gestures. The researchers hope the mind-controlled avatar, which was created through a joint medical engineering project involving Keio's Department of Rehabilitation Medicine and the Tsukigase Rehabilitation Center, will one day help people with serious physical impairments communicate and do business in Second Life.

Ideal for short trips around town, the PIXY is designed to transport individuals along sidewalks and into buildings. The PIXY fits inside the SSC for longer trips, and a shared control system allows the driver to operate the SSC from inside the PIXY. The PIXY can also be coupled with a sports car unit called the SSF and a boat unit called the SSJ.

WAO-1: Face massage robot

10 Oct 2007

WAO-1 face massage robot -- On October 9, professors Atsuo Takanishi of Waseda University and Akitoshi Katsumata of Asahi University unveiled an oral rehabilitation robot, called "WAO-1" (Waseda Asahi Oral Rehabilitation Robot 1), which is designed to help treat mouth, jaw and facial disorders by performing therapeutic face massages. In November, the developers will begin clinical testing of a prototype robot -- built by dental X-ray equipment manufacturer Asahi Roentgen -- on patients in Yokohama.

Equipped with two 50-cm (20-inch) arms that protrude from a chair-sized aluminum box, WAO-1 performs massages by pressing the patient's face from both sides. Each arm's position and angle can be precisely controlled, as can the direction of the pressure applied to the face. WAO-1 also relies on a complex system of software and fuses to ensure the pressure does not exceed a certain level, and it is equipped with a "torque limiter function" that allows the arms to bend back should the robot begin to exert too much force. Much of WAO-1's control technology, which can also be found in humanoid robots, is the product of Takanishi's well-known work on robots that walk and express emotions.

While the parts for the prototype cost about 8 million yen ($70,000), Takanishi says the robot is cost-effective because it can be used to massage other body parts and perform other tasks like hold a patient's mouth open during treatment.

Facial massage, which is known to combat dry mouth because it stimulates salivation, is used in the treatment of various mouth and jaw disorders. An estimated 10 million people in Japan are believed to suffer from oral conditions such as dry mouth and temporomandibular joint disorder -- a condition that makes it painful to open the mouth, which is sometimes caused by stress or age. WAO-1's creators, who are confident they can develop a commercial version soon, hope the robot can take advantage of the lack of skilled practitioners in this high-growth area.

Ig Nobel Prize: Vanilla flavoring from cow dung

05 Oct 2007

Vanillin -- Mayu Yamamoto, a former researcher at the International Medical Center of Japan, has won this year's Ig Nobel Chemistry Prize for developing a method for extracting vanillin -- an ingredient in vanilla fragrance and flavoring -- from cow dung.

According to an AFP report, Yamamoto, who attended the award ceremony at Harvard University on October 4, said, "At first I thought it was a joke, but I came to the award ceremony hoping my research would become more widely known." Yamamoto says that widespread adoption of her method could help the environment because companies would make greater use of cow dung, which arguably contributes to global warming.

As a bonus prize, Toscanini's Ice Cream in Cambridge, Massachusetts has invented a new flavor -- Yum-A-Moto Vanilla Twist -- to honor Yamamoto, and is offering a free public tasting to its customers on October 5.

The annual Ig Nobel Prizes are meant to honor scientific achievements that "first make people laugh, and then make them think," according to the founders at science humor magazine Annals of Improbable Research.

Yamamoto is 12th Japanese person to receive an Ig Nobel Prize since the awards were established in 1991. Previous award-winning achievements from Japan include the invention of karaoke, which received the Peace Prize, and the Tamagotchi, which received the Economics Prize.

Teleglass T4N wearable monitor --

Optical device maker Scalar has added a limited-edition model to its line of video glasses. The Teleglass T4-N wearable monitor, which weighs 30 grams and features titanium frames by eyeglass designer Kazuo Kawasaki, was developed in cooperation with long-established manufacturer Masunaga Optical.

Teleglass T4-N connects to any NTSC-capable video player (including iPods) and delivers images directly to the eye via a pair of tiny monitors tucked away behind the lenses. The 640 x 480 screen resolution at close proximity simulates the effect of watching a 45-inch screen from 2 meters (6 feet) away, and each monitor can be focused and adjusted for an optimal picture that reduces eye strain. Audio is delivered through a pair of frame-mounted earphones.

With all the components hidden behind the lenses and crammed into the nosepiece, the lightweight Teleglass T4-N wearable monitor looks like a pair of stylish sunglasses. The monitors do not completely obstruct the view, allowing users to safely and comfortably enjoy audio-video entertainment during the course of everyday activities.

For now, 500 sets are available through the Scalar website, where they sell for 134,400 yen ($1,150) each.

Clannad canned bread in Akiba vending machine

04 Oct 2007

Canned bishojo bread -- A vending machine at Tokyo's Akihabara station is now offering a limited run of canned bishoujo bread in celebration of the new Clannad TV anime series that begins October 4.

Clannad, which was first released as an interactive love adventure game (visual novel) for the PC in April 2004, follows the adventures of a high school delinquent as he develops relationships with some of his female classmates.

The 350-yen ($3) canned Clannad treats -- available in chocolate, strawberry, green tea, butter, raisin, blueberry, and milk -- are manufactured and distributed by Pan Akimoto, who originally developed canned bread as an emergency food in the aftermath of the 1995 Kobe earthquake. In Akihabara, where cuisine like canned oden enjoys widespread popularity, the future of canned bishoujo bread looks bright.

A vending machine on platform 6 (for Sobu line trains bound for Chiba) will be dispensing the canned bread until the end of October.

DIY wooden keyboard kit

04 Oct 2007

Ki-Board DIY Kit --

Hacoa, a brand known for its high-quality, hand-made wooden keyboards and peripherals, will soon begin offering a do-it-yourself type keyboard kit that allows the purchaser to cut the keys from a plank of wood and assemble the pieces.

Yamaguchi Kougei, the wood products and lacquerware dealer based in Fukui prefecture that created the Hacoa brand, typically crafts each keyboard by hand in a labor-intensive process that allows them to complete one keyboard per day. The slow production process makes it difficult for the company to fill large orders and prompts them to charge around 50,000 yen ($435) per keyboard. However, Hacoa's new "Ki-Board DIY Kit" (ki, which sounds like "key," means "tree" or "wood" in Japanese) aims to lighten the company's labor load -- and boost production and lower prices -- by letting the purchaser do some of the cutting and assembling at home.

The kits, which come in maple or walnut, include a USB keyboard base, a wooden plank with the beginnings of keys carved into it (the letters have already been hand-carved into each key), connectors for attaching the finished keys to the keyboard base, a saw, sandpaper and other tools.

Marubeni Infotec plans to market and sell the kits through their monoDO website, which is scheduled to go online October 18. The kits will be priced at around 34,800 yen ($300) each.
