Scientists Show Thought-Controlled Computer at Cebit

G.tec of Austria demonstrated a brain-computer interface (BCI) at the Cebit
trade show that allows the user to control a computer - albeit in a limited
capacity - by measuring the electrical voltage fluctuations in the user's
brain via a cap studded with electrodes. The electrodes rest on the scalp and
are linked via cables to a "biosignal amplifier," which sends the signals
from the brain to a computer. The BCI uses software that must be
painstakingly trained to interpret the brain signals so that they can be
translated into the proper actions. Functions the g.tec BCI can perform
include writing letters, operating prosthetic limbs, and steering a
wheelchair. Such technology could become very useful for people who are
movement- or speech-impaired. "Ultimately you could have wireless contacts
embedded in the brain, and communicate with others just by thinking," said
g.tec CEO Christoph Guger. He explained that BCI research is currently a
focus of 300 laboratories.
