Consideration of physiological effect of robot assisted activity on dementia elderly by electroencephalogram (EEG): Estimation of positive effect of RAA by neuroactivity diagram

Electroencephalogram (EEG) measurement on dementia elderly in nursing home was carried out in order to estimate positive effect of robot assisted activity (RAA). AIBO (ERS-7, SONY ERC) was used as robotic pet for RAA session. Neuroactivity diagram was derived from EEG data by using `Dimension´ (BFL; Brain Function Lab.). It was found that improvement of neuroactivity was observed after 15 min. RAA, especially RAA by using remote controlled robot. We also investigate neuroactivity change by RAA for normal young subjects, and Data showed that RAA was not so effective for young person.
