Twittering For Those Who Can’t Talk Or Type

If you can think it, you can post it — on Twitter, that is.

A new device developed by researchers at the University of Wisconsin-Madison allows users to tell a computer what to do simply by concentrating on a letter or action on the screen.

The device relies on a brain monitoring cap. The person wearing the cap focuses on the letter they want to display and the device uses brain monitoring to tell the computer which letters to “type.”

So far researchers are using the technology to post messages on Twitter, a network that allows users to publish messages of up to 140 characters at a time.

Researchers say the device has huge potential for people with normal brain function whose disabilities limit what their bodies can do.
