Zuska is the kick-ass alter-ego of Suzanne E Franks. When not dispensing Zuska's wisdom, Suzanne can often be found gardening, reading, or having one of her thrice-weekly migraines.
By way of the Chronicle News Blog...researchers are using a brain-computer interface to allow physically-impaired people move an avatar around in Second Life.
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.
There is a video on the Chronicle News Blog post.
