The paper presents results from a project aiming to create horizontally distributed surround sound sources and virtual sound images as auditory BCI (aBCI) stimuli. The purpose is to create evoked brain wave response patterns depending on attended or ignored sound directions. The authors propose to use a modified version of the Vector Based Amplitude Panning (VBAP) approach to achieve the goal. The so created spatial sound stimulus system for the novel oddball aBCI paradigm allows them to create a multi-command experimental environment with very encouraging results reported in this paper. They also present results showing that a modulation of the sound image depth changes also the subject responses.
