This doctoral research aims to enhance the Quality of Life (QoL) of People with Dementia (PwD) by developing a personalized musical robot to provide support through music and reminiscence activities. Our research is dedicated to creating and facilitating meaningful activities, while reducing agitation and improving PwD’s mood. Key studies include the development of a music recommender system based on episodic memories, robotic assistance in daily activities through schedule-related music, and collaborative storytelling involving the PwD and their informal caregivers. These interventions are intended to support emotional regulation and communication. This PhD is part of the QoLEAD project, which integrates multidisciplinary research to bridge the gap between AI and warm care in dementia.
