| Outline of Final Research Achievements |
Patients with amyotrophic lateral sclerosis (ALS) that progress to the total locked-in state (TLS) cannot use alternative devices for communication, which depend on motor functions. These devices are often used in occupational therapy for patient support, but are not applicable in such cases. We have engaged in basic studies for the development of BCI that use P300 ERP elicited by auditory stimulus, because users do not require particular trainings for eliciting P300, and eliciting P300 does not depend on visual function. The results of the present study suggested that bone conductive sounds were useful for BCI. There are some advantages of using bone conductive sound. For example, the bone conductive headphones do not need to cover the external auditory canals, which would allow the user to listen to conversations with other people while wearing these headphones. In addition, it is sufficient to use a bone conductive transducer at only one location for excitation.
