  • Scope
    • This study provides a comprehensive test of the head–related impulse response (HRIR) to an auditory spatial speller brain–computer interface (BCI) paradigm, including a comparison with a conventional virtual headphone–based spatial auditory modality. Five BCI–naive users participated in an experiment based on five Japanese vowels. The auditory evoked potentials obtained produced encouragingly good and stable P300–responses in online BCI experiments. Our case study indicates that the auditory HRIR spatial sound paradigm reproduced with headphones could be a viable alternative to established multi–loudspeaker surround sound BCI–speller applications.
