Tangermann, M. Publication year 2012 Abstract Giving direct feedback on a mental state is common practice in motor imagery based brain-computer interfaces (BCI), but has not been reported for those based on eventrelated potentials (ERP). Potentially, such feedback could allow the user to adjust his strategy during a running trial to obtain the required response. In order to test the usefulness of such feedback, spatially congruent vibrotactile feedback was given during an online auditory BCI experiment. Users received either no feedback, short feedback pulses or continuous feedback. Results showed that feedback had a deteriorating effect, both on classification performance and behavioral scores (target stimulus counting). Furthermore, most subjects preferred the no feedback condition over those with feedback. Under these conditions, the use of direct feedback in ERP based BCIs can thus not be recommended.
