Oct. 12, 2007 — Japanese researchers say they have found a way to let people stroll through the virtual world of Second Life using their own imagination, in a development that could help paralysis patients.
Previous studies have shown people can move computer cursors through brain waves, but the Japanese team says it is the first to apply the technology to an Internet virtual world.
The technology "would enable people suffering paralysis to communicate with others or do business through chatting and shopping in a virtual world," said Junichi Ushiba, associate professor at Keio University's rehabilitation centre.
Second Life is an increasingly popular virtual world in which people — and animals — are represented by animated avatars and can do everything from social activities to shopping.
Ushiba said Second Life could motivate patients with severe paralysis, who are often too depressed to undergo rehabilitation.

"If they can see with their own eyes their characters moving around, it could reinvigorate their brain activity and restore some functions," he said.
Under the technology, a person wearing head gear embedded with electrodes, which analyse brain waves in the cerebral motor cortex, would be able to move a Second Life character forward by thinking he or she is walking.
