Abstract: An auditory attention tracking system may modify external sounds in a manner that enables the system to detect, from EEG readings taken while a user listens to the modified sounds, which sound the user is paying attention to. Multiple microphones may record external sounds, and the sounds may be separated. A computer may modify one or more of the sounds, then remix the sounds, and then cause speakers to audibly output the modified, remixed sound. EEG measurements may be taken while the user listens to this modified sound. A computer may detect patterns in the EEG readings and may, based on the patterns, predict which external sound the user is paying attention to. The system may further modify the external sounds, to make the sound of interest more perceptually prominent. Or, based on the detected sound of interest, the system may modify a human-computer interaction.
