Twitter Telepathy: Researchers Turn Thoughts Into Tweets

[Reposted from sgLEAD]

From Wired, 20 Apr 09 (the article explains why Twitter works better than trying to get patients to email):
Early on the afternoon of April 1, Adam Wilson posted a message to Twitter. But instead of using his hands to type, the University of Wisconsin biomedical engineer used his brain. "USING EEG TO SEND TWEET," he thought.

... The researchers built upon the BCI2000, a software tool pioneered by Williams and Wadsworth Center neural injury specialist Gerwin Schalk. The software translates thought-induced changes in a scalp's electrical fields to control an on-screen cursor.

Williams described e-mail as a a relatively difficult and inefficient task for someone on a brain-computer interface.

"It's difficult enough to be able to spell words, much less find an address book and select names. The overhead involved in these applications is just too much," he said. "Twitter is very serendipitous. It handles all the things that we've been struggling to make easy for a patient to do. It puts messages where people can find them. Let the world know how you're doing, what you're thinking, and they'll find you. And that's perfect for these patients and their families."

Something that Singapore polytechnics or universities might want to try prototyping?


  1. This is the first time I heard about BCI2000. Thanks.

    Is the BCI2000 now available to the market?

  3. I've no idea, Heidi. The best source is the BCI2000 website
