Researchers Look to Turn Brain Power into Tweets
From: PC World - 04/22/2009

System would allow those who can't communicate to do so using Twitter.

Some might say using your brain to Tweet would ruin Twitter, but University
of Wisconsin-Madison and Wadsworth Center (Albany, NY) researchers have good
cause for working in this area: They're looking to help improve
communications for people whose brains work but are without use of other
parts of their bodies typically used to communicate (those with ALS, spinal
cord injuries, etc.) 

The system translates brain activity into changes on a computer screen that
create Tweets.

Researchers Use Brain Interface to Post to Twitter
From: ACM TechNews - 04/24/2009

University of Wisconsin-Madison biomedical engineering doctoral student Adam
Wilson recently posted a status update on Twitter using only his thoughts.
The message, "using EEG to send tweet," demonstrated a way for locked-in
patients, those with no movement capabilities, to use brain-computer
interfaces to communicate. Wilson is a part of a research effort to develop
communications systems for people who cannot move but have normal brain
function. "We started thinking that moving a cursor on a screen is a good
scientific exercise," says UW-Madison professor Justin Williams, Wilson's
advisor. "But when we talk to people who have locked-in syndrome or a
spinal-cord injury, their No. 1 concern is communication." The new
communication interface is based on brain activity related to changes in an
object on a screen. The interface displays a keyboard on a computer screen,
with each of the letters flashing individually. If a patient is focusing on a
single letter and nothing is happening, there is no change in brain activity,
but once that letter flashes, the brain recognizes that something is
different and there is a momentary change in brain activity. Wilson says it
is a slow process at first but that users improve as they use the interface,
reaching up to eight characters per minute. The brain-based Twitter
communication system represents one of the first uses of brain-computer
interface techniques and Internet technologies, says Wadsworth Center
research scientist Gerwin Schalk, who contributed to the project.
