In a fascinating nexus of accessibility and social media right here in the state of Wisconsin, a researcher posted a message on Twitter using a brain-computer interface system — basically by thought.

Adam Wilson, a student at the University of Wisconsin-Madison researching biomedical engineering, posted the message “using EEG to send tweet” by using technology in which the letters of the alphabet flashed individually on a screen, and the computer was able to gauge brain activity, selecting the desired letter when brain responds to it flashing.

Such technology has a long road to go before being mainstream, but its successful test on an Internet application opens up tremendous potential in enabling those whose bodies are inoperable to communicate and interact online.
