Please Blink Your Password: Converting Morse Code Eye Activity to Text using EEG

In Electroencephalograph (EEG) readings, eye blinks are considered an obstacle to brain-oriented analysis. Blinking causes a distinct disturbance in the time series, allowing one to track when eyes open and close. Many programs aim to filter out these blinks from EEG data by recognizing and erasing them. The potential of blink readings, however, can be utilized instead of eliminated: these readings can be used as a safer version of LED eye-blink reading. In this research, EEG is used to convert eye blinks in Morse code into text for possible application in alternative computer interfaces and as a factor of authentication.
