Reflection Support System Based on an Attention Behavior Model for Cooking Cognitive Rehabilitation

We have conducted ADL cognitive cooking rehabilitations for dementia patients and higher brain dysfunction people to promote their self-reliance. This paper focuses on attention behavior during cooking rehabilitation. We propose a cooking attention behavior model integrating an attention flow extracted from a cooking task model in a top-down manner with a saliency map configured from an early human vision model in a bottom-up manner. Moreover, we systematize the proposed model as five attention behavior indexes that are derived from the recognition outputs of cooking state and propose a reflection support system based on their indexes. Finally we verify the validity and reliability of the proposed system through evaluation experiments.
