Veikko Saikkonen 9.1 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.
Bart Vastenhouw 1.1 4
Sofia Kostakonti 3.1 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?"
Sofia Kostakonti 6.1 7 RQ3: "Does the robot remind the PwD of their hunger?"

Veikko Saikkonen 9.1 11 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.

Veikko Saikkonen 9.1 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.

Sofia Kostakonti 2.1 17 == Experimental design ==
Bart Vastenhouw 1.1 18
Veikko Saikkonen 9.1 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.

Veikko Saikkonen 9.1 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.

Sofia Kostakonti 2.1 25 == Measures ==
Bart Vastenhouw 1.1 26
Veikko Saikkonen 9.1 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.

Sofia Kostakonti 2.1 29 == Procedure ==
Bart Vastenhouw 1.1 30
Sofia Kostakonti 4.1 31 * Welcome Participants and explain what they are going to be doing.
32 * Have them sign the permission form.
33 * Participants complete a questionnaire(A) regarding their emotional state (control).
34 * Have version A of interaction with the robot.
35 * Complete questionnaire(extended version).
36 * Have a short interview during downtime (prepared questions).
37 * Have version B of interaction with the robot.
38 * Complete questionnaire(extended version).
39 * Have a short interview during downtime (prepared questions).

Bart Vastenhouw 1.1 42
Veikko Saikkonen 9.1 43 For the experiments, we'll be using the NAO robot platform, as well as a laptop for the participants to complete the questionnaires on. 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.

Aleksanteri Hämäläinen 11.1 45 == Practicalities ==
Bart Vastenhouw 1.1 46
Aleksanteri Hämäläinen 11.1 47 Beforehand:
48 * Do a practice round by ourselves
49 ** Film this
50 * Contact other groups and decide on a time slot
51 ** Might be better to reserve in 10 min slots, so that people don't have to wait so much
52 ** If possible, this could be done in parallel with another groups testing
53 * Reserve lab
54 * Buy snacks
55
56 During:
57 1. Give starting questionnare to fill while people are waiting for the previous participant
58 2. Guide the participant to the testing spot
59 3. Inform the participant where the snacks are
60 4. Run the first version
61 5. Give the mid-questionnare
62 6. Run the other test
63 7. Change the participant in the room, and give the previous participant the end questionnare outside the testing area, to speed up the process
64
65
66 Other practicalities during:
67 * We will use the "Wizard of Oz" method for recognizing agreement and disagreement, to make sure that the whole process does not depend on voice recegnition being good enough
68 ** Someone will press eg. "y" and "n" on the keyboard according to the participants answers
69 * We will change the order in which the smart and basic versions are for each participant
70 ** this way if someone doesn't show up, we don't get skewed amounts
71
72 After:
73 * Analyze results

89 Setup:
90 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.
91
92 Topics:
93 - Emotions before / during / after the interaction with the robot
94 - Agitation due to the robot suggesting eating
95 - Effect of music on the general feeling of the situation
96 - Feeling of company during eating
97 - Effectiveness of eating/drinking suggestions
98
99 Guiding questions:
100 - Did you eat or drink anything?
101 - Were you feeling hungry/thirsty beforehand?
102 - Did the discourse change this?
103 - How likely would you have eaten/drank without the robot suggesting it?
104 - Scale 1-5
105
106 - What did the interaction with the robot feel like?
107 - With the more intelligent version?
108 - With the less intelligent version?
109 - What did you feel like when the robot suggested you should eat/drink?
