A fundamental study on the adaptive assistive technology based on brain-inspired systems from the viewpoint of wearable devices and social interactions

We focused on a spontaneous perception-action cycle in the human daily activity, as a clue to design a wearable device that cooperatively assists the activity by showing information on demand. As a fundamental study on such adaptive assistive technology, motivations to external objects, human counterparts and social communications were analyzed through eye tracking experiments that we designed from an inspiration from the Horticultural Therapy. The result revealed a significant difference between cases with artificial objects and natural scenes, which may help to know the human brain activity on visual attention and emotional bias. In addition, we built a BCI-based EEG stimulus presentation system and analyzed a possible application for EEG-EOG data segregation.
