World’s First Demonstration Experiment on Using Brainwaves to Chat and Stroll Through Second Life

Keio University applied the technology “to operate the computer using brain images released last year and succeeds in enabling a disabled person suffering muscle disorder to stroll through “Second Life®, to walk towards the avatar of a student and to have a conversation with the student using the “voice chat” function.

On 7th June 2008, Keio University succeeded in the World’s First Demonstration Experiment with the Help of a Disabled Person To Use Brainwave to Chat and Stroll Through the Virtual World

The research group led by Assistant Prof. Junichi Ushiba of the Faculty of Science and Technology of Keio University applied the technology “to operate the computer using brain images (*1)” released last year and succeeds in enabling a disabled person suffering muscle disorder (41 year old male) to stroll through “Second Life® (*2)”, a three-dimentional virtual world on the Internet, to walk towards the avatar of a student logged in at Keio University located 16km from the subject’s home, and to have a conversation with the student using the “voice chat” function.

This demonstration experiment opens a new possibility for motion-impaired people in serious conditions to communicate with others and to engage in business. This experiment is a marriage of leading-edge technologies in brain science and the Internet, and is the world’s first successful example to meet with people and have conversation in the virtual world.

This research is an achievement of the Biomedical Research Project (*3) at Keio University, a collaboration project of the Faculty of Science and Technology, Tsukigase Rehabilitation Center and the Department of Rehabilitation Medicine of the School of Medicine. This experiment was demonstrated at the 17th Keio University Faculty of Science and Technology Open Lecture on 7th June 2008.

At the demonstration, a student in a remote location (Yagami Campus) will move an avatar using brainwaves, and this (live video footage and the moving avatar) will be shown within Second Life®. Live video footage of the lecture (held at Hiyoshi Campus) will also be shown within Second Life®. The lecture itself will be streaming, where the real world and virtual world will be mixed.

2. About the developed technology
The system uses electrodes as small as 1cm in diameter that are attached to the scalp. A computer detects brainwaves from the sensory-motor cortex when the subject slightly moves fingers of his/her right and left hand, and moves the avatar accordingly. The computer also detects the subject’s will to move forward, and makes the avatar move forward. The system released last year used a desktop computer, but the new system uses a portable electroencephalograph commercially available, and made it possible to bring the system to the subject’s home. The subject walks toward the avatar controlled by a student, and talks to it. Moving images of this demonstration experiment can be seen at the following website:
3. Development in the Future
Detection of brainwaves will become more accurate, which will lead to smoother control of avatars. The technology will be used to develop communication tools and business tools to support the lives of people with serious movement disorders.

(*2) “Second Life®”, a 3-D Virtual Community Service
Second Life® is a 3-D virtual community, created and operated by U.S.-based company Linden Lab, with a growing population from more than 100 countries around the globe. Residents of Second Life® can create their own homes, vehicles, nightclubs, stores, landscapes, clothes and games. They control avatars, which are characters to replace themselves, to stroll through the virtual world and teleport. Chatting with other residents and commercial activities are also possible. Linden dollars, the virtual currency used in Second Life® can be changed to real US dollars.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
