Abstract
A Brain-Computer Interface (BCI) is the interface which enables users who cannot move their own body freely due to amyotrophic lateral sclerosis to manipulate machines at their own intention. The BCI system has been developed in particular area, such as inputting characters or moving a wheelchair. In contrast, the system combined BCI with Augmented Reality (AR) links markers to real objects and enables users to solve tasks directly in real life, so the system is assumed to be used in many situations. In this study, we added auditory stimuli into the AR-BCI system, and we developed a multimodal AR-BCI system and evaluated efficacy of simultaneous visual and auditory stimuli. In detail, subjects were given only visual, only auditory or visual and auditory stimuli, and we measured P300 for attended and unattended stimuli.
