The portable cushion with our software provides sound and vibration to the back, enhancing the feedback experience. Can be incorporated into standard EEG protocols, providing an additional feedback modality. Also useful with any game or soft-ware that produces sounds. Sensitive, accurate vibrotactile feed-back provides pleasant and immediate rewards for any desired EEG program. Experience a pat on the back when those theta or beta waves reach their desired levels. Or, sit back and let the Interactor Cushion™ feed your alpha waves directly into your body. Can be used for laptop, hand or arm feedback as well as auditory feedback as an extra duty speaker that really gets the low sounds across.* Works on Windows 95,98, ME, XP & 2000.
