Biomedical engineering doctoral student Adam Wilson has successfully tested a "brain wave monitor" to the Twitter publishing interface, allowing him to compose a message merely by thinking and publish it to the arguably too-popular microblogging service.
Technically, what Wilson did was come up with an interface combining an Electroencephalogram, or brain wave monitor, with an on screen keyboard for selecting letters. The system lights up each key on the keyboard but is able to notice a difference in brain activity when the desired letter for input is lit. Wilson compares it to clicking through multiple letters when texting on a mobile phone. More at; http://www.readwriteweb.com/archives/twitter_thoughts.php
