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.

15 -As there are practical difficulties with conducting the experiment with actual people with dementia due to both time constraints and COVID, our participants' group will consist of peers from other groups and friends, who will act as if they are older people with dementia. We plan to gather around 20 people for our experiments.

19 -We will be using a within-subject design. In the experiment all of the participants will interact with both versions of the robot, with half of the participants interacting with the version 1 first and then version 2, and the other half in reverse order, to counter-balance the carryover effects. Snacks will be made available for the participants, in case they're prompted and they're hungry. The participants will be unaware of the possibility of eating snacks, to prevent disturbing the interaction with the robot. Otherwise the subjects could be primed for eating, which would bias the results and hide the effect of the robotic interaction.
19 +We'll be using the within-subject design. All of the participants will interact with both versions of the robot, 10 of them with version 1 first and then version 2 and the rest the reverse, to counter-balance the carryover effects. We also plan on having some snacks around, available for the participants to eat in case they're prompted and they're hungry. We do not plan on telling them about it beforehand, since we do not want to create that association in their minds before interacting with the robot.

23 -The participant will have to interact with the robot, which is programmed to engage in a lunch discourse. Two versions will be implemented: the first version will ask basic questions about mealtime, mostly acting as a reminder for the PwD to have lunch (alarm clock). The second will be our original implementation of it with the more sophisticated discourse and music.

27 -We plan on measuring the effectiveness of the discourse, both physically and emotionally. Our quantitative measure is whether the person ate the lunch they were supposed to have eaten, and the qualitative measure is the emotions that the PwD experienced before, during, and after the interaction. The qualitative measures will be recorded with a simple questionnaire. Depending on the time of the experiments, we assume that people might also not be hungry enough to be prompted to have something to eat, which might disturb the results. We do plan however to measure whether the robot will remind someone of their hunger and have them eat.

The questionnaire will be a combination of questions regarding the emotional state of the participants, their interaction with the robot, and the music included in the interaction. Food will be made available to see and measure how much people will eat.

60 -Setup:
61 -The test subject has finished both parts of the experiment. Before leaving the test conductor(s) sit down with them and ask the following questions in a discussion about the experiment. Discussion can flow freely, but the following topics should be discussed.
62 -
63 -Topics:
64 -- Emotions before / during / after the interaction with the robot
65 - - Agitation due to the robot suggesting eating
66 - - Effect of music on the general feeling of the situation
67 - - Feeling of company during eating
68 -- Effectiveness of eating/drinking suggestions
69 -
70 -Guiding questions:
71 -- Did you eat or drink anything?
72 -- Were you feeling hungry/thirsty beforehand?
73 - - Did the discourse change this?
74 -- How likely would you have eaten/drank without the robot suggesting it?
75 - - Scale 1-5
76 -
77 -- What did the interaction with the robot feel like?
78 - - With the more intelligent version?
79 - - With the less intelligent version?
80 -- What did you feel like when the robot suggested you should eat/drink?
