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

12.06.2008
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: http://www.bme.bio.keio.ac.jp/01news/
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.

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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
