Caregiver's Gaze and Field of View Presumption Method During Bath Care in the Elderly Facility

Reduced mental fatigue and ease of mind on caregivers are crucial in order to deliver safe bath care assistance in the elderly facility. In this paper, we present an experiment quantifying the eye gaze and field of view of the caregiver while performing bath care assistance. First, we used optical motion analyzing apparatus, head mounted gaze measuring apparatus, motion sensor (applied to 5 points: wrist, waist, neck, head and ankle in sequence) and compared data. Subjects imitated the motions of bathing assistance in a laboratory. Second, we clarified the validity of data by studying simultaneously recorded multiple people’s data taken under role play settings (caregiver role and care receiver role) in an actual bathroom setting. The findings of the study are highly relevant in outlining a safe and secure bathing assistance related to reducing the mental burden on caregivers as well as giving them “ease of mind” while performing bath care.
