3 3  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.

5 -RQ1: "Does the robot cause PwD to eat more regularly?"
6 -RQ2: "Does the PwD experience less negative emotions, such as agitation, sadness, embarrassment, after the interaction with the 'intelligent' robot?"
7 -RQ3: "Does the robot remind the PwD of their hunger?"
8 -RQ4: "Does the music make the eating more enjoyable for the PwD?"

213 +In improving the eating, the advanced robot does perform better. While the margin is slight, it would seem that both robots could cause the patients to eat more regularly, if triggered by timers or other suitable systems. It also seems that the advanced robot is better in the reminding, by a slight margin. However, the long term effects of reminding should be researched more to conclude whether the usage of the demonstrated robot platform or similar would cause the patients to eat more regularly.
