Abstract
The system and methods described herein determine a subject's indication of attention to a first and a second sensory stimuli. The system determines a sensory evoked response of the subject by calculating the statistical relationship between the subject's neural response to the stimuli and a signal feature of the first and the second sensory stimuli. A magnitude value of the sensory evoked response is extracted to determine whether the subject attended-to or ignored the sensory stimuli. The system will select the stimuli that elicited the greater indication of attention, and then trigger further processing by a computer. Such processing can include selecting future content for improving safety warnings, educational materials, or advertisements or further processing can include controlling and navigating a brain computer user interface.
