The P300 speller allows users to spell letters just by thoughts. Its interface consists of letters arranged in a matrix, and the user’s desired letter is determined by recognizing the P300, elicited by flashing the row or the column containing the letter. Flashes are repeated to improve the accuracy in exchange for the speed. This paper proposes reliability-based ARQ (RB-ARQ) and its selective repeat variant, RB-SR-ARQ. RB-ARQ employs the maximum posterior probability as a stopping criterion for the stimulus presentation. RB-SR-ARQ selects stimuli to be flashed based on their posterior probabilities. Consequently, the accuracy can be improved compared with the standard averaging with a small loss of the speed.
