  People with dementia often forget to eat and drink, leading to dehydration, malnutrition and decreased wellbeing in general. Our prototype engages in discourses to remind PwD to have lunch and drink water, using the Nao robot platform. The discourse aims to reming the PwD without causing any anxiety or embarrassment which a traditional "alarm" system could cause, and keep them company throughout these activities.
--RQ1: "Does the robot cause PwD to eat more regularly?"
--RQ2: "Does the PwD experience less negative emotions, such as agitation, sadness, embarrassment, after the interaction with the 'intelligent' robot?"
--RQ3: "Does the robot remind the PwD of their hunger?"
--RQ4: "Does the music make the eating more enjoyable for the PwD?"

  The prototype is evaluated with an in-person experiment with multiple participants. In the experiment, the participants will be asked to pretend to be PwD and act accordingly with/without the prototype.
