Changes in the time segment length after a performed classification in case no distinct classification can be made and the actual time allows for the extension to the next predefined value. After each classification (gray bars of 8, 10 20, and 160 blocks), additional time for gaze shifting was included (black) in which the classifier output was rejected for 9 blocks.
