Is it possible to classify the character without knowing the row-column information?
p300 signal is generated when human are looking at flashing light. From the EEG signal correctly detection of p300 is important. After detection of p300 our job is to find what time this p300 signal generated and at that time instant which row or column flashed. From this row-column combination we can get the original character.
Now if I don't have the row-column information. Is this possible to detect the character from EEG signal?
