title: Two communication lines in a 3 × 3 matrix speller.
abstract: In a matrix speller both eye fixation and attention are reflected in the event-related potentials to highlighting of characters. We consider the question of whether this can be used to open up two parallel channels by dissociating the attended character from the fixated one. Complementary classifiers for both characters are established and their relationship is investigated.
