Send an Email Through Brain Activity

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 Email through brain activity using a T9 suggestive text approach (reduce stress). This is a low cost solution as it makes use of a commercial EEG acquisition, Thus the time taken to send an Email is less compared with making use of the P300 approach.
