Using Brainwaves To Chat And Stroll Through Second Life
The system uses tiny electrodes that attach to the scalp, which allow the user to move a character in any direction, as well as 'will' the avatar forward. It detects minute movements in the nerves in the hands to detect which direction they want to move.
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 released last year and succeeds in enabling a disabled person suffering muscle disorder (41 year old male) to stroll through “Second Life®*”, 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.
