Research Summary

Mihoko Otake

AI nurturing or complementing intelligence of human are becoming much more important than ever before. Cognitive Behavioral Assistive Technology (CB-AT) Team puts emphasis on developing CB-AT which promotes cognitive reserve for prevention of cognitive decline and dementia of older adults which damage the intelligence of human necessary for social life. We develop conversational assistive AI based on Coimagination method, implement the AI to cognitive behavioral assistive systems, and evaluate the effects on human cognition and mind. Coimagination method is an image-based conversational assistive technology designed for utilizing cognitive functions which decline at mild cognitive impairment.
