People who have severe movement disorders like Amyotrophic Lateral Sclerosis (ALS) or Locked in Syndrome, is a condition where a patient is awake and aware of its surrounding but unable to communicate or perform any action due to paralysis of almost every voluntary muscles in the body (with the exception of eye movements and blinking). Imagine patients having a fully functional brain trapped within a non-functioning body. The brain of the patient would be fully conscious and aware of its surroundings, it could think and process stimuli, but unable to translate thought into action. This is caused by a gradual degeneration of the nerve cells in the central nervous system that controls voluntary muscle movement.

Therefore the author suggest a non invasive Electroencephalogram (EEG) based Brain Computer Interface (BCI) that could provide a new control channel to individuals with severe motor impairments, A application that would enable individuals to communicate with the outside world. The non-invasive method of BCI suggested by the author is considered a safe procedure as it requires no brain surgery and causes no harm to the patient under any circumstance.

Here, we see a subject trying to send an Tweet through brain activity. This is a low cost solution as it makes use of a commercial EEG acquisition, Thus the time taken to send an Tweet is less compared with other similar projects.

@AlexRoxUrSox Well i guess ur wrong .. The launching part of it is automated too. You might see that theres some fast typing of the path of the program, this path is hardcoded. so when the user launches the program the path gets printed automatically. That is where u see the fast typing. at certain points u might also see the mouse moving, and might have felt suspicious over the application. Here's better video that demonstrates this /watch?v=4qNUSuNgRk4

@AlexRoxUrSox What do u mean by keyboard inputs ? Do you say that i am using my hands to select words ? If so its a 'NO'

@rick0cn No, this is not the p300 brainwave. It's hard to stimulate a p300 brain wave with a single sensor EEG acquisition.

that looks awesome! I am also working on BCI, so is it P300 you are using?
